    Diamond Price Guidelines: How Diamonds Are Priced

    Diamond prices are impacted by the usual dynamics of supply and demand. Simply put, availability and rarity will drive prices higher.

    Quality factors will also dramatically impact the price of a particular diamond. These factors are often referred to as “The 4 C’s:” carat, cut, clarity and color. Learn more about The 4 C’s here.

    Diamond prices start to increase exponentially as you go up in carat weight and hit the "magic" carat weights such as .5 carat, 0.75 carat and 1 carat.

    Shape, which is different than cut, is another pricing factor. For example, round shaped diamonds typically cost more. Read our tutorial about diamond shapes here.

    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.

    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.
