How are diamonds priced ?

Diamond Colour is one of the 4c’s used to calculated diamond value

Polished diamond prices are derived from a variety of factors, including supply and demand, the quality and characteristics of the individual diamond, and market conditions.

The prices of polished diamonds are primarily determined by the 4Cs: carat weight, colour, clarity, and cut. These factors are assessed by gemologists and other experts who evaluate the diamond’s physical properties, such as its size, colour, clarity, and overall quality of cut.

Other factors that may influence the price of polished diamonds include the type of diamond, such as whether it is a natural or lab-grown diamond, the country of origin, and the overall market conditions for diamonds. Additionally, the reputation and credibility of the seller or the dealer can also affect the price of the polished diamond.

Overall, polished diamond prices are determined by a complex combination of factors, and can fluctuate over time based on changes in supply and demand, market conditions, and other economic and industry factors.
There is no single diamond price list that accurately reflects the prices of all diamonds. This is because the price of a diamond depends on a number of factors, including its size, shape, colour, clarity, and other characteristics.

That being said, there are various industry-standard diamond price lists that are commonly used as references by professionals in the diamond trade. These lists are typically based on a standardized grading system and provide price ranges for diamonds of different sizes, shapes, and quality grades.

The most commonly used diamond price list is the Rapaport Diamond Report, which provides a benchmark price for diamonds based on their 4Cs grading (carat weight, colour, clarity, and cut). However, it is important to note that the Rapaport price list only reflects the wholesale price of diamonds and may not necessarily reflect the retail price that consumers will pay.

Other diamond price lists include the International Diamond Exchange Price List, the Idex Diamond Price Report, and the Polished Prices Diamond Index, among others. These price lists may differ in their methodologies and grading systems, and the prices they list may vary slightly from one another.

Ultimately, when buying or selling a diamond, it is important to work with a reputable and knowledgeable diamond professional who can help you evaluate the diamond’s characteristics and provide you with an accurate price estimate based on current market conditions.

Rough Demand Stable at $450M De Beers Sight

De Beers reported steady demand for rough diamonds at its December sight as sales showed an increase over the equivalent period last year.

The miner sold $450 million worth of rough in its final sales cycle of the year, including last week’s sight in Gaborone and its auctions, it reported Tuesday.

Provisional proceeds rose 6.6% compared with actual sales for the same period last year, though they slipped 3.4% from November sales.

Synthetic Diamond Fraudulently Inscribed To Match Natural Diamond Report

Improvements in diamond growth technology and methods have led to a noticeable increase in colorless synthetic gem diamonds in recent years. Concerns in the diamond industry focus on laboratory-grown diamonds not being properly disclosed or even being sold as natural stones. Through careful examination and analysis, gemological laboratories can separate natural from synthetic diamonds. Occasionally, however, fraud is involved in attempting to conceal a gem’s identity. The Carlsbad laboratory witnessed such an attempt.
On this occasion, a round brilliant cut (figure 1, left) was submitted for an updated diamond grading report. Its girdle was inscribed with an actual GIA report number issued in 2015 (figure 1, right). The older report was for a natural, untreated diamond and contained the following grading information: 1.74 ct, round brilliant cut, D color, Excellent cut grade, and VVS₁ clarity. Upon grading, the new submission was described as a 1.76 ct round brilliant cut with F color, Excellent cut grade, and VS₁ clarity. Moreover, our screening processes determined that the newly submitted sample needed additional testing to determine its origin. This examination revealed it to be an HPHT-grown synthetic diamond. Synthetic cuboctahedral growth structure and phosphorescence were clearly visible in DiamondView imaging (figure 2).

Figure 2. DiamondView imaging showed the synthetic growth structure and blue phosphorescence typical of HPHT-grown synthetic diamonds.

Aside from the observed discrepancies in weight (1.74 vs. 1.76 ct), color (D vs. F), and clarity (VVS₁ vs. VS₁), FTIR spectra clearly showed that these were not the same diamond. The natural diamond from the original report was type Ia with aggregated nitrogen impurities, while the new one was type IIb with boron impurities (figure 3). Careful examination of the report number inscribed on the synthetic diamond revealed a font different from the one used by GIA, proving that it was not an authentic inscription.

Figure 3. FTIR absorption spectra revealed that the synthetic diamond was type IIb, whereas the fraudulently inscribed report number referred to a natural type Ia diamond. The spectra are offset for clarity.

While most synthetic diamonds that come to the laboratory are properly disclosed, some are submitted out of concern that a stone presented as natural might be synthetic. Rarely do we encounter the type of blatant fraud described here. It is important for the industry and public to exercise caution, because these types of misleading practices do occur. We believe the submitting client noticed inconsistencies with the GIA report information and sent it to the lab for an updated report. If any doubt exists or some aspect of a diamond (such as an inscription) seems odd, the stone should be sent to a gemological laboratory for verification.
