Diamond Price Guide: How Diamonds Are Priced

How are diamonds priced?

Diamonds are priced according to the 4 C’s. Diamond carat weight and diamond color tend to have the most impact on the price. However, many factors contribute to the final price of any particular stone.

Here are 7 factors of diamond prices, starting with the 4 C’s:

Carat Weight:
Carat is the weight or size of the diamond. It is the simplest and only truly objective pricing factor.
Diamond Color:
Diamonds are found in many colors. Subtle differences have a big impact on price.
Diamond Clarity:
Clarity refers to the absence of imperfections or inclusions. Diamonds with perfect clarity are very rare.
Diamond Cut:
Diamond cut creates the sparkle and brilliance. A good cut can make a lower quality stone more valuable.
Diamond Shape:
Rarity and demands of shapes such as hearts, ovals, radiants.
Diamond Grading:
Most diamonds sold online have grading reports or “certs” from independent labs. This grading can impact the diamond price.
Market Factors:
Supply and demand affect diamond prices as it does every product and service. Diamond prices can fluctuate greatly.

Carat Weight:

Diamond prices have been historically priced on a per carat bases. It is still common in brick and mortars and business-to-business transactions. For example: a 0.75-carat (also know as a 75 pointer) priced at $4000 per carat, would cost $3000 ($4000 x 0.75= $3000). As more consumers are using the Internet to educate themselves about diamonds and make purchases, diamond prices are starting to reflect the total diamond price for simplicity and clarity.

Diamond Color:

Most diamonds have hints of color, and subtle color differences have a big impact on diamond prices. Diamonds are actually found in many colors, but the majority of diamonds available will have tints of yellow or brown. Colorless diamonds are very rare, as they contain little to no impurities and are essentially chemically pure. Some prefer higher clarity diamonds and are prepared to sacrifice color for “purity,” while others deem high color paramount, and will hold it above the other 4Cs.

Diamond Clarity:

Clarity refers to the existence of internal and external imperfections that characterize an individual diamond. It may also be referred to as “purity” or “quality” in the diamond trade. Diamonds with perfect clarity are very rare, as most diamonds will have microscopic inclusions or blemishes. There are many factors that determine a diamond’s clarity.

Diamond Cut:

Out of the 4Cs, diamond cut has the biggest impact on sparkle, brilliance and fire. The vast majority of diamonds for sale are not of great cut quality. Well-cut diamonds sparkles and looks more beautiful than a diamond with a worse cut. Diamond Cut can trump the other 4Cs by turning a diamond pebble into a sparkling gem.

Diamond Shape:

Fancy shapes are not you traditional Round diamond choices but are as beautiful and rare. Fancy cuts are not easy to judge by number and are unique to the individuals that choose them. Due to demands not as high as rounds, they are difficult to compare prices on.

Diamond Grading:

Almost all diamonds sold online and better quality, larger stones sold in the stores come with a grading report, or ‘cert’. Diamonds are typically graded by one of three prominent gem labs: GIA, AGS or EGL. These labs may grade the same diamond differently, which could create a significant disparity in pricing or valuation. When comparing prices between suppliers be sure they have used the same grading laboratory.
