Frequently Asked Questions

How are diamonds priced?

Diamonds are priced by diamond dealers based on the market for similar diamonds of the same shape, color, clarity, and other key characteristics. Most jewelry professionals discuss diamond prices in terms of price per carat and then calculate the diamonds final price by multiplying price-per-carat by carat weight to solve the diamond’s final price.

How much does a diamond cost?

Diamond prices vary significantly based on the diamond’s shape, color, clarity, carat weight, fluorescence, polish, symmetry, and other important factors. For example, an expensive 1 carat D color IF clarity diamond can cost over $20,000 while a 1 carat K color SI2 clarity diamond currently costs closer to $2,500. Most shocking though is that many people would have a hard time telling the difference between these two diamonds, especially when they are set in an engagement ring setting or diamond stud earrings.

How much are diamonds worth?

Diamonds are more valuable than just about any other naturally occurring mineral based on weight, particularly jewelry quality diamonds like those in the colorless, near colorless, and faint colored diamond color grade ranges. A gram of gold is currently worth less than $100, while 1 gram of diamond would equate to a 5 carat stone which could be priced at over $400,000.

While they are expensive, diamonds are not considered a good investment since most jewelers and websites will only offer about 50% of the original price for a diamond on the resale market. Recycled diamonds are becoming more popular and offer a great, sustainable alternative to lab grown diamonds.

How much do lab grown diamonds cost?

In general, lab grown diamonds cost about 67% less than natural diamonds. This price relationship changes over time along with changing consumer sentiments over natural and lab grown diamonds but generally speaking lab grown diamonds have always been far less expensive than natural diamonds despite being chemically identical and physically indifferentiable.

Some consumers unfairly ask the difference in price between real diamonds and fake diamonds, but it is generally understood now that due to their physical composition lab grown diamonds are very much “real diamonds” despite being manufactured in a lab.

What is diamond price per carat?

Diamond price per carat is the pricing methodology that jewelers and diamond dealers use to discuss diamond prices in the same way that real estate agents talk about home prices in terms of “price per square foot”. To calculate a diamond’s price per carat, simply divide the total price by the number of carats. For example, if a 2 carat diamond costs $20,000 then the price per carat for that diamond is $10,000 per carat.
