What colors are gemstones?
Nature has been conjuring its magic on the creation of precious stones for more than one millennium, so each mineral is unique and inimitably beautiful in its own way. Finding your exact gem in the sparkling labyrinth of jewelry stores is extremely difficult. To do this, you need to learn a few simple rules. There are only four characteristics that allow you to accurately evaluate and select gems:
Gem color
- Redgemstones: ruby, tourmaline, garnet, coral significantly activate energy potential, inspire, give courage, power, valor. They will further strengthen the determination of a self-confident person and, on the contrary, can weaken the fighting spirit of those who doubt their uniqueness.
- Green gemstones: emerald, peridot, tourmaline, tsavorite – the personification of spiritual harmony, inner peace, prudence. This tone is perfect for truly holistic individuals with a philosophical outlook on life.
- Blue gemstones: sapphire, avamarine, turquoise, topaz – an excellent choice for those who want to develop patience, practicality, intuition, strengthening logical abilities.
- Whitegemstones: diamond, leucosapphire, zirconium, white topaz – a symbol of perfection, purity, refinement of taste, as well as an indicator of high status and openness. Excellent for developing hard work and selflessness.
- Purple gemstones: alexandrite, amethyst, tanzanite, morganite – the color of mystical secrets. He will become an assistant to those who strive to develop qualities such as responsiveness, sensitivity, honesty and focus.
- Cabochon – the oldest and at the same time the simplest type of grinding, which is most often used when working with opaque or translucent crystals. The method “makes” such minerals shine, since the rays acquire the ability to be reflected from the surface of the crystal. Star-shaped gems also look amazing in “cobochon”, delighting the eye with a flashing hexagonal star.
- Circle – another classic of jewelry making, allowing craftsmen to create a huge number of facets and, accordingly, real designer masterpieces. The disadvantage of this type of grinding is the high consumption of material, the loss of which sometimes reaches half of the total mass.
- Pear used for processing mainly medium and large stones, giving them a drop shape. The side bevels here resemble wedges, thereby providing an original play of light. The drop-shaped cut is especially good for gold earrings with stones – they look feminine and elegant.
- Marquis – a kind of tribute to the memory that the jewelers paid to the Marquise de Pompadour, the favorite favorite of Louis XV. The boat-shaped shape with pointed and somewhat oblong tips is somewhat reminiscent of the flirtatious smile of a famous lady. The cut is suitable for working with fragile stones, preserving their integrity.
- Baguette – a find for stepped minerals of rectangular shape. When choosing such jewelry, it is important to pay attention to the quality of processing of the crystals used, since the baguette emphasizes not only the advantages, but also the errors of this cut.
- Oval – a new type of grinding, which can be called a modified version of the “wheel”. This is what is most often used for working with diamonds. The oval looks best in a ring.
- Couchon – a very fashionable quadrangular cut in recent years, which appeared only in the 20th century. It is better to take transparent or translucent stones, large ones from 0.5 carats – they look great in rings or pendants. This is a pad shape that involves the wide edges and convex sides of the stone. The cutter rounds the corners, giving the stone incredible brilliance and shine, while also preserving the weight of the stone.
- Heart
It is believed that this cut is used for stones that have a defect that will be too obvious with a round cut, and in the “heart” the gemstone will open to its full potential, while this type of cut is very complicated, since symmetry is required between the faces of the two halves, plus maintain the proportion in size: on average 0,75 to 1,25, and not allow a deviation in the upper part of less than 32 and more than 36 degrees. But usually the result of these efforts is simply fascinating: yes! Yes! Yes! – the girls shout after receiving a gold ring with a heart-shaped stone as an engagement gift. - INSTRUCTIONS ON HOW TO CHECK THE QUALITY OF JEWELRY

How to determine the purity of stones?
Minerals that come into the hands of craftsmen from natural mines are often covered with cracks and scratches. During processing, rock with a huge number of different inclusions is cut off. Only a relatively small part of the mass remains, suitable for making jewelry.
Initially pure stones without admixtures of other minerals are a real rarity, so they are very expensive. We can say this: the value of a stone directly depends on the number of other fragments it contains. True, such an assessment does not need to be approached linearly. Say, blue topaz, aquamarine or citrine actually have a small amount of inclusions and are highly valued due to their purity. But emeralds and rubies often contain other elements, but this does not prevent them from belonging to the category of the most exclusive and expensive stones. The secret of this feature is quite simple – inclusions are recognized as their piquant unique feature. In short, in the world, as always, everything is relative.
Cutting a colored stone
For colored stones, the geometric proportions of the cut are not as strict as for diamonds. However, even in this case, a professionally selected form plays an extremely important role, since it is able to create a subtle play of shades, hide or advantageously use inclusions, and achieve the desired symmetrical outlines.
In jewelry, a technique called “facet” is also used. Such facets are applied to the surface of the mineral in order to achieve the effect of internal radiance of colored rays under the influence of external light.
Most often, jewelers use the following stone cuts:
Dimensions and weight of stones
The unit of measurement for the mass of gemstones is the carat, which is equal to 200 mg. The higher the carat value, the more expensive the gem is. However, the substantial size of a mineral may not always indicate its great weight. Let’s say, a ruby and a diamond of the same mass will be different sizes, because the first has a denser structure.
Gemstone Sizes: Round Diamond Cut
Large stones are less common than small ones, and therefore cost more, but there is no exact proportional relationship between price and size. For example, a small emerald will force you to pay an order of magnitude higher than a large peridot. At the same time, a ruby weighing 5 carats will cost much more than two similar stones weighing 2,5 carats.

October 1, 2022 Jewelry is an item of personal use, so you should choose it not only by logic, but also by taste. One of the key criteria is color. Fortunately, nature has proven itself to be a talented colorist, and the colors of precious and semi-precious stones are counted in dozens of types. We offer you a layout guide that will help you quickly navigate and find what you need.
The main thing that determines the color of a stone is light
The hue of a mineral is determined by its ability to absorb or reflect rays from the white light spectrum. Such light contains all the colors of the rainbow, and each of them has its own wavelength. Gems that absorb all types of waves appear black. Reflecting 100% of the waves, they are perceived by the human eye as white or colorless.
It is important to know what the color of a stone depends on so as not to overpay for a low-quality product. The value of a nugget, among other things, is determined by its saturation, tone and lightness. The price of two gems of the same type, but of different saturation, may differ by 2 or more times.
At the same time, controlling the perception of color is quite simple – just change the lighting. Fluorescent lamps enhance blue, violet and green hues. Incandescent lamps – red, yellow, orange. This is actively used by unscrupulous sellers who seek to present their product in the literal sense of the word in the best light, in which the stone seems brighter. Special gemological lamps with a wave frequency of 365 nanometers are considered ideal for color assessment.
Gems by color
If you decide to buy a really expensive product, the choice will be limited, but it will still be there. The layout of gems by color is as follows:
colorless – diamonds or polished diamonds;
White pearls;
pink – sapphires, diamonds;
red – rubies, sapphires;
orange – sapphires, rare types of amber, diamonds;
yellow – sapphires, rare types of amber, diamonds;
green – emeralds, sapphires, diamonds;
blue – sapphires;
blue – sapphires, diamonds;
purple – sapphires, diamonds;
black – pearls, diamonds;
pink-green – alexandrite.
In accordance with the law of the Russian Federation, these types of gems are called precious, and in the jewelry classification they are considered stones of the first order.
Semiprecious stones
