What is this diamond really worth?
Skip the formula and the sales pitch. Tell us the four Cs, or just describe the stone in plain English, and see the real price 100+ retailers are charging for it right now, each scored the same way. We sell nothing and take no commission, so the number you see is the real one.
LucyDiamond analystFreeYou are looking at a G VS1 round, 1.50ct natural. Ask me whether that price is fair and I will find the same stone cheaper across retailers.
A real price, not a formula
Other calculators multiply a few numbers and guess. We show what your exact diamond is actually selling for today, across more than 100 retailers.
See the spread, keep the difference
The same stone often costs 30 to 80% more at one store than another. On a 1 carat that is an average of $1,737 left on the table. Knowing the real range is how you stop overpaying.
Priced by data, not commissions
We do not sell diamonds and we take no retailer commission. The price you see is the real market price, not a number built to close a sale.
