Precious blue and light blue sapphires

  • (Cornflower Blue) cornflower blue – crystals of a “cornflower blue” tone are distinguished by their “silkyness” and the effect of a weak internal glow. These properties are associated with the presence of rutile inclusions that reflect light rays. The reference point is the blue color of the cornflower flower, but for sapphires it is a whole range of colors from bright blue to bright blue, but not dark. It is important to note that for the Russian market, cornflower blue velvet blue stones are more suitable than royal blue ones. The reason for this is a large number of cloudy days, as a result, “royal blue” sapphires in our band can look dark and lose their charm, unlike Asia, where they look very expensive and aristocratic.
  • (Peacock blue) the color of the bright blue of a peacock’s neck or the feathers on its tail – this bright blue color is found in sapphires from Sri Lanka, another name for this spectacular color is “electric blue”. Not all laboratories around the world classify this color as a separate category, but on the market it has long been entrenched between cornflower blue and royal blue. This color looks very bright in any type and brightness of lighting.
  • (Royal Blue) Royal blue is the most expensive variety of blue sapphires. Royal blue is a range of shades of rich, deep blue, but not black. The boundaries of this color range vary among laboratories around the world; for example, at GIT (Gemological Institute of Thailand), the set of samples of Royal blue sapphires also includes dark blue shades. As we have already written above, in Russia such samples of sapphires look dark, so you need to buy sapphires only after seeing the stone in person. Sapphires of this color category are usually used in their collections by jewelry houses of the Graff level.

Refinement of blue and cyan sapphires

Most of the crystals (90%) go through refining, which improves their quality characteristics. Basic methods for refining blue sapphires:

  • Heat treatment is the most common method of refining. The technology is based on long-term heating of raw materials in an oven at a temperature of 900-1800 degrees. After heating, a change in color to a more saturated one is observed. In addition, you can lighten sapphires of dark shades, change the color, and thereby increase the price. The effectiveness of the method is based on the melting of thin needle-shaped rutile inclusions, which sometimes cause inappropriate color tones. Also, crystalline mineral inclusions in the stone melt under the influence of high temperature and also become less noticeable, improving purity. Of course, refined sapphires differ in price from untouched natural stones.
  • Titanium diffusion is the high-temperature heating of already faceted sapphires with the addition of titanium oxide. Due to its lower atomic mass, titanium penetrates into the surface layers of the stone, coloring it in a more saturated blue or blue color. It is easier to diagnose this refining than heat treatment; by placing the diffusion sapphire with the surface facing down on a white sheet of paper, you can observe an increase in the concentration of color along the edges of the faces.
  • Filling cracks with cobalt blue glass – under the influence of high temperature and pressure, the glass penetrates cracks, “healing” them and improving the clarity of fractured stones.

There are samples that were subjected to all three methods of refining at once. Their cost is very low and does not exceed $20-40 per carat.

It is also important to remember that there are artificial sapphires on the market that are grown in specialized production facilities. Synthetic sapphires often have excellent quality characteristics. However, they have a very low cost and are supplied to the jewelry market in large quantities. Gemological laboratories test sapphires and issue documents indicating the true origin of the stones.

What affects the cost of blue sapphires?

The “4Cs” principle of diamond pricing (Color, Clarity, Weight and Cut) is only partially applicable to the pricing of blue sapphires. The cost of blue sapphires is affected by:

  • The color of a sapphire is the most important characteristic; it is the color and its saturation that can dramatically increase the cost of a blue sapphire. Above we have listed and described the most expensive color varieties of blue corundums: Royal blue, Peacock blue and Cornflower blue.
  • Weight – the weight of the stone greatly affects the cost, especially for natural unrefined sapphires. The cost per carat increases stepwise with increasing weight of sapphire in the following weight categories: 1-3 carats / 3-5 carats / 5-7 carats / 8-10 carats and samples over 10 carats. It is important to note that, for example, the price of one carat of blue sapphire from the 1-3 carat category and the 5-7 carat category may differ by two or more times. This rapid increase in cost can be observed every one or two weight categories.
  • Clarity – sapphires often have rutile light needle-like inclusions, giving a “silky” appearance to the stones’ edges. There are gas-liquid and solid mineral inclusions that affect the cost. When evaluating a rare crystal of bright blue color, the purity of the mineral affects the price, but is not the main criterion. Natural high-quality stones and artificial sapphires can have ideal transparency. Therefore, when purchasing pure stones, you need to make sure that you have an expert opinion confirming their natural origin.
  • Cut – The quality of the cut often affects the cost of sapphires. Unlike diamonds, colored stones do not have strict cut parameters, but symmetry, polish and proportion are important in showcasing color. Asian cutting quality is very low and this applies to both cheap and expensive stones. This is explained by the pursuit of a larger mass of stone at the exit, so the samples are often “drawn” – with deep pavilions, which greatly reduces the “face” of the stone, making it visually smaller than stones with the same weight, but with a proportional pavilion. Another sign of a bad cut is a large area, which creates a large window with a dip in color. Often, in order to maximize the color of a sapphire, recutting is required, which involves losing a significant portion of its mass.
  • Refinement – untreated samples of blue sapphires cost on average 1,5-2 times more expensive than refined sapphires of similar color and size. In this case, we are talking only about heat treatment of crystals, since other methods of refining (coloring with titanium diffusion and filling cracks) reduce the cost of sapphire much more.
  • Origin – deposit also affects the cost of blue sapphires. The most expensive sapphires are those from Kashmir (India). But the Kashmir deposit has long been worked out and closed; stones from private collections can occasionally be found on the market. The second place is occupied by sapphires from Burma (Myanmar); high-quality Burmese sapphires over 5 carats are very rare. Burmese origin significantly increases the cost of stones compared to Sri Lankan origin. It is Sri Lanka that ranks third among these famous sapphire-bearing regions. Today, most high-quality blue sapphires come to the market from Sri Lanka. Sapphires from Madagascar are often as beautiful as those from Ceylon, but their cost is slightly lower. Madagascar is a young region compared to the first “branded” three deposits, but experts predict an increase in value in the future for samples from Madagascar. Already, we do not see a significant difference in cost per carat for top-quality stones from Sri Lanka and Madagascar. Despite this, miners from Madagascar continue to bring raw materials to Sri Lanka and pass them off as local Sri Lankan ones, in pursuit of extra profit.
  • Certification – the absence of an expert opinion from a leading gemological laboratory can slightly reduce the cost of blue sapphire, but this also poses the risk that the stone may be heated or have a different origin from the declared one. The world’s most authoritative laboratories that can determine not only the natural origin and refinement, but also the mining region: GRS, GIA, Gubelin Gem Lab, SSEF, AGL, Lotus, AIGS. In Russia, we recommend checking colored stones at the Moscow Gemological Center of Moscow State University and MGL – Moscow Gemological Laboratory.

Cost of blue sapphires

The price of natural sapphires of beautiful blue shades is growing every year, and global demand is also growing. It is impossible to provide price statistics for top large (8-10 and 10+ carats) blue sapphires in the Royal blue, Cornflower blue and Peacock blue color categories. The sale of each such precious sample is a complex bidding process between the buyer and the dealer, often such transactions are closed. The average prices for Ceylon blue unrefined sapphires of the highest jewelry quality in the weight category of 8-10 carats are determined by the world market as follows: $5.000-8.000 per carat. Unique samples from Burma in the same weight category are significantly more expensive – $10.000-18.000 per carat. This quality of sapphires is very rare.

Let’s give a price range for the characteristics of blue sapphires that are more popular in the market – this is an average weight of 3-5 carats with varying levels of jewelry quality, but without taking into account the mining region:

  1. Low (commercial) quality – in this category are sapphires that have been subjected to diffusion or heating. The colors are either light or too dark. There are inclusions. Price range: $50-500/carat.
  2. Good quality – in this group there are blue sapphires with or without heat treatment, but light blue colors; the purity of such stones is usually not impeccable. Price range: $600-1.600/carat.
  3. Very good quality – in this category there are blue sapphires of bright blue colors without refining or only heated ones, but in top shades. The purity of such samples is good, but there may be inclusions barely visible to the eye located on the periphery of the stone. Price range: $1.700-3500/carat.
  4. Excellent quality – only untreated stones of the most expensive color varieties (Royal blue, Cornflower blue and Peacock blue) with a good cut and visually clean. Price range: $3.600-5.000 US dollars per carat.

Optical effects of blue sapphires

  • Color change is an optical effect in which color changes under different lighting conditions. In daylight, the stone has a blue tint, and in artificial light it changes to violet.
  • Asterism – this optical effect is characteristic of cabochon-cut star sapphires. On a smooth surface, a star with six rays is observed, sliding along the surface as the stone rocks. A beautiful star increases the cost of the sample, so there are imitations of this optical effect – the so-called “induced” stars, which are artificially applied to the surface of the stone. A distinctive feature of the imitation is the absence of displacement of the star when the gem is swayed.
  • “Cat’s eye” is the movement of a white light strip along the surface of a cabochon-cut sapphire. The occurrence of these two optical effects is due to the presence of rutile threads throughout the minerals. A certain orientation in a rutile crystal is responsible for the manifestation of asterism or “cat’s eye”.

Minerals that have optical effects cannot be subjected to heat treatment, since rutile melts at high temperatures.

Deposits of blue and blue sapphires

The most beautiful jewelry designs come to the market from:

  • India (Kashmir) – the field is closed
  • Burma (Myanmar)
  • Sri Lanka
  • Madagascar

Sapphires of lower quality and darker color are mined in: Australia, Thailand, Cambodia, Laos, Vietnam, Tanzania, Nigeria.

To the average person, sapphires evoke images of a shimmering blue gemstone. While this opinion about sapphires is true, there is much more to the gemstone than the usual stereotypes.

Sapphire rings

For example, sapphires are not just beautiful. They are also quite strong. In fact, it is the second hardest gemstone after the super-hard diamond. Moreover, as beautiful and mesmerizing as blue sapphire is, sapphires are not limited to just the color of the sky. They can be any color of the rainbow and even have colorless varieties. Here are ten amazing facts about sapphires that you probably didn’t know at all:

1. Sapphire is one of the four precious stones

The terms “stones” and “gems” are thrown around quite often, but for the most part, almost all gemstones come from some kind of mineral (except for rare exceptions such as pearls). Not every stone is a gemstone, which is used almost interchangeably with the term “precious.” This is because some are considered more valuable than others and only a select few are in the gemstone category. In fact, the distinction between precious and semi-precious stones is no longer used. However, many people differentiate between the two groups. A stone becomes precious once it has been transformed from its rough mineral form into a cut and polished gemstone. The richest gemstones on the planet—diamonds, emeralds, rubies and sapphires—are referred to as precious stones. All other precious stones are called semi-precious. Some are much less valuable than gemstones, while others can be quite expensive.

2. Sapphires and rubies have the same structure

While regarding gemstones, it must be noted that two of these gemstones have the same structure. This means that sapphire and ruby ​​are actually the same type of stone. The only significant difference is that rubies have an exquisite red color. The unique color of the ruby ​​was enough to identify it as a gem, but other than the element that causes the red color, the two stones have the same structure. Only rubies with a strong red color are considered rubies, while lighter stones are known as pink sapphires.

3. Sapphires rank 9th on the Mohs scale

But those who are familiar with the world of gemstones know that one of the aspects is the hardness of the stone. The popularity of a diamond, aside from its one-of-a-kind brilliance, is that it is the hardest substance known to man. It ranks 10th on the Mohs hardness scale, the highest. However, next in scale and still quite impressive is the sapphire, as well as the ruby. This makes both of these gemstones phenomenal options for jewelry as they are durable and can withstand a little knocking.

4. The 4 Cs criteria apply to sapphires, although in very different ways

Many interested in the world of diamonds may be interested to know that the 4Cs are also used to grade colored gemstones. However, it is important to understand that they are used in completely different ways. First, while color, cut, clarity and carat are considered equally when grading colorless diamonds, they are not considered in the same way when grading sapphires. The main reason for this is that the color of the sapphire has absolute priority over everything else. We are not looking at the absence of color, as is the case with colorless diamonds, but at the presence of color. We don’t just look to see what color it is, but what secondary colors are present, how intense the color is, and how dark or light the stone is. In official terms, the color, tone and saturation of a sapphire take precedence over all other aspects, including clarity, carat and cut. Additionally, although high-quality sapphires are preferred, their quality is graded differently than a diamond. A sapphire may have inclusions and may still be considered extremely valuable. It all depends on where the defect is found, how noticeable it is, and whether it can be seen in comparison to the overall color and appearance of the stone.

5. Sapphires come in different colors

Known mainly for their blue variety, sapphires appear in a variety of colors, including pink, orange, yellow, green, purple, colorless and black. These stones make a fabulous alternative to their more expensive colored diamond counterparts, although some types of fancy sapphires can also be quite expensive.

6. Sapphires are made from a mineral called Corundum.

Most precious stones and semi-precious stones are minerals, and sapphires are no exception. They are a type of the mineral corundum, which is also classified as rubies.

7. Color changing sapphires

They differ from the various colored sapphires in that there are several unique types of sapphires that stand out from the rest. One such type is the color-changing sapphire. As its name suggests, this unusual sapphire displays different colors when it is exposed to natural light and artificial light.

8. Star Sapphires

A special type of sapphire is the star sapphire. As a result of imperfections within the stone, sapphire can display an asterism that resembles a star, hence the name. These sapphires are incredibly rare and highly sought after. There are also star rubies.

9. Sources of sapphires

Sapphires are mined in various locations around the world, but mainly come from Cambodia, Colombia, India and Kenya. Other areas include Afghanistan, Australia, Nepal, the United States and Vietnam.

10. Sapphire cut

While the color of a sapphire is its most important feature, the cut is a close second. This is because the way the sapphire is cut directly affects its color. Therefore, the center of the sapphire must be cut in such a way that it reflects light and color. If the center is dead and does not reflect light or color, it is called a window. Sapphires with large windows command much lower prices for this very reason.

Like everything in life, there is always a trade-off, and like everything else, different things attract different types of people. Therefore, unless you are adamant and insist on getting the biggest, best quality sapphire with the best color and are able to afford it, it is advisable to carefully consider what is most important to you. Size? What about the color? What about the form? What about the quality? The larger the stone, the more likely it is to have inclusions. On the other hand, smaller stones are likely to have fewer flaws. So if you want the best, you need to be willing to pay this price.
