Quick answer: what is the typical markup on diamonds?

The average markup on a GIA certified Lumera diamond is less than 9%, which means the end consumer is paying very close to a true wholesale price (the price charged by diamond cutters around the world). This compares favorably to a traditional jeweler, which might mark a diamond up 100% or more.

This means that you won’t ever make money reselling a diamond that you purchased new from a jewelry store. Even if the store buys it back from you at 100% of its new market value, there’s a significant markup placed on the new diamond that you won’t get back. The second factor is how much the diamond is worth.

While the factors above all influence the resale price of an engagement ring, in general you can expect to get 20-45% of the original retail price. If you sell your ring to a jeweler, this number will be affected by their markup. Larger stores will likely have a higher markup than your local independent jeweler.

Markup. A standard markup for retail fashion stores is around 56 percent. For example, a store takes the cost of an item and multiples it by 2.3. Thus, when an item costs the store $25, that number is multiplied by 2.3, to get $57.50. This is the price a store should sell this item at to attain the 56 percent margin.

In other words, if my cost is $100 and I add 30 per cent to it I'm going to end up with a selling price of $130. To calculate a 30 per cent MU you divide the cost by the decimal reciprocal of the markup value--$100/.7 = $142.86 which gives you a margin (or profit) of $42.86.
