The budget option is a natural certified diamond with the latest acceptable characteristics, which allows you to save money for other projects.
The level of characteristics of this diamond is truly at the lower limit.
With the rarest exception, if you go down even one more level, you can spend money and not get the desired result.

Color – J. The author recommends being careful about stones yellower than H, but if you have a limited budget, J is still possible. Cleanliness – Si1. Although the author has repeatedly encountered stones that are clean to the eye, even with Si2 purity or, in the rarest cases, PI, it is Si1 purity that is borderline. For some, the inclusion is not visible without a magnifying glass, for others it is visible. The author believes that it is his responsibility to find good Si1s when the client’s budget is limited. Choosing a bad Si1 will save you $100-200 but will give you poor visual results. Therefore, access to a large number of diamonds, allowing choice, is very important for both very high and very low budgets. Cut quality – the only thing in which you need to be quite strict, because the proportions, symmetry and polishing are collectively designated as a cut – Cut and the brilliance of the crystal depends. It is advisable not to go below Very Good. In international trade, the unit of 1 carat equal to 0,2 grams is used to determine the weight of a diamond. Weight is not the only, but important criterion for determining the price of the most expensive stones in the world. The cost of a cut diamond depends on the high cost of raw materials. To obtain a round diamond weighing 1 carat, it is necessary to process over 1 million tons of ore. The quality of the stone, market conditions and other factors also matter.

How is the market regulated?

In Russia, price lists are controlled by Gokhran, which is part of the Ministry of Finance. The characteristics of stones are assessed according to TU 117-4.2099-2002. In international diamond transactions, the Rapaport Diamond Report is usually used. The publication has been published weekly for round cut stones and monthly for fancy cut stones since 1978. Prices determine the maximum amount diamond dealers can offer to wholesale buyers. The cost for the end consumer is affected by subsequent markups and discounts.

Price range for 1 carat diamonds in Russia

A cut round diamond of 1 carat is currently valued on the Russian retail market at an average of 400 thousand rubles for stones of medium clarity with a tint, up to 2 million rubles for selected, absolutely colorless minerals. Fancy cut diamonds (“pear”, “princess”, “heart”, “emerald”) are valued in the range from 250 thousand rubles to 1,5 million rubles, respectively.

Expert opinion

How does the cost of a diamond carat differ on the secondary market: All other things being equal, the price of a diamond on the secondary market is on average 20–40% of the cost offered by retail stores. It is important to understand that in retail the numbers are greatly inflated. These include retailer and reseller markups, premiums for brand and frame style, advertising costs and other factors. If you compare offers with similar ones from specialized gemstone sellers, the cost will be approximately 70%. Buying diamonds on the secondary market is profitable in any case; it is only important to make sure of their authenticity and quality.

How is the value of cut diamonds determined?

The price of precious stones is influenced by the following factors:

  • Size. The price for 1 carat of diamond is not the same when it comes to stones of different weight categories. With the transition from one group to another (for example, from 0.9–0.99 to 1.00–1.49 carats), the cost of a conventional unit of weight changes by an average of 20–40%. Therefore, jewelry with dozens or hundreds of small inserts are cheaper than a solitaire with one large mineral.
  • Color. Among traditional stones, other things being equal, those with the least intense shade are most valued. Ideal stones should become invisible when placed in water. The yellower the mineral, the cheaper it is. In the case of fancy yellow, cognac, black, blue and other rare diamonds, on the contrary, the brighter and more saturated ones win in price.
  • Purity. The presence of inclusions, defects or microcracks reduces the market value of stones, even if they are invisible to the naked eye. The GIA system has 6 levels – from FL (absolutely free of inclusions) to VS (very small defects visible under a microscope with 10x magnification) and I (imperfections noticeable without magnification).
  • Cut. The Rapaport Diamond Report price list is available in two versions: for round and fancy diamonds. The former are valued most highly, among the latter the most expensive are “drop” or “pear”, and the cheapest are “emerald” cut stones.

In the international grading system, these parameters are designated as 4C: carat (carat, or weight), color (color), clear (purity), cut (cut).

Specialized Certificates

The presence of a certificate determines how much a diamond can be sold or bought for. Famous brands usually use stones certified by the prestigious American institutes GIA or AGS, international organizations HRD or IGI to make rings and other jewelry. These are expert laboratories that provide the most complete list of evaluation characteristics of the quality of precious stones. With such a certificate, diamonds can participate in professional transactions around the world and receive the highest possible valuation. In some cases, stones with a GIA certificate are twice as expensive as similar stones that have passed laboratory tests at HRD, AGS, and EGL centers.
