Size & Shape
Carat is the single biggest driver - doubling weight roughly quadruples the price at the same quality. Shape stacks on top: rounds carry a 10–30% premium over ovals, cushions, emeralds and pears.
Diamond Search Engine: Compare Prices on 500,000+ Diamonds
Every listing is scored 1–5 against today's Fair Market Price, so you can spot a genuine deal at a glance. Filter below to find yours.
How The Diamond Price Score works
Every result is compared to the Fair Market Price for its exact shape, carat, color, clarity and cut, then scored 1–5: 5 (Best Deal / Perfect Deal) is 20%+ below fair, 4 (Great Deal) is 10–20% below, 3 (Good Price) is any amount below fair, 2 (Fair Price) is at or slightly above fair, and 1 (Above Market / Overpriced) is 40%+ above fair. Full methodology: thediamondprice.com/research/methodology.
What you can search and filter
This diamond search engine covers 500,000+ natural and lab-grown diamonds, tracked in real time from our authorized retail partners. Filter by shape (round, oval, asscher, princess, cushion, pear, radiant, marquise, emerald), carat (0.25–15), price, color (D–K), clarity (FL–SI2) and cut (Excellent–Fair) — plus advanced filters for fluorescence, polish, symmetry, table %, depth % and length-to-width ratio. Every result links to that exact stone on the retailer's site, and each is scored against the live Fair Market Price for its specification — something a static price chart can't do.

How pricing works
What Affects Diamond Price?
Every diamond’s value comes down to four big levers - size and shape, colour and clarity, cut and certification, and live market availability. These are the same inputs behind every Fair Market Price on this page.

High impact
Colour & Clarity
D–E and Flawless command real premiums, but to the naked eye F–G and VS1–VS2 usually look identical once mounted. Stepping down one bracket each typically saves 25–45% combined.
Medium impact
Cut & Certification
Cut quality is what makes a diamond actually sparkle - Excellent or Ideal is non-negotiable. A trusted lab report (GIA or AGS) commands a real premium over EGL or IGI grading because the grades are stricter and more consistent.

Live Market Availability
Supply, demand and the depth of current listings move prices day-to-day. When inventory for your spec tightens, prices climb; when it deepens, you have more negotiating room. That’s why every estimate here uses live diamond prices, not stale lists.
Buyer tip - the just-shy carat trick.
Choose a carat weight just under a round number (0.90–0.95 instead of 1.00, or 1.85–1.95
instead of 2.00) to save 10–15% for a stone that looks visually identical face-up.

Diamond Search FAQ
Common questions about searching, comparing and buying diamonds through The Diamond Price.
How many diamonds can I search?
Over 500,000 diamonds, tracked in real time from our authorized retail partners. Every listing shown is real, current inventory - not a sample or an estimate.
What's the difference between Best Overall and Best Deal?
Best Deal is always the single lowest-priced diamond in your current search. Best Overall is the diamond we'd personally choose - the strongest balance of cut, color, clarity and price - which is sometimes a small step up from Best Deal, not always the cheapest option. Both are computed from your current search results, and each shows its own "Why this pick?" reasoning.
Are these real, in-stock diamonds?
Yes. Every result links directly to that exact diamond on the retailer's own site, where you can view its certificate, additional photos and complete the purchase. We don't hold inventory ourselves - the search shows what our authorized retail partners currently have listed.
How often is pricing updated?
Listings reflect live retailer inventory. The Fair Market Price benchmark shown against each result is recalculated in real time as that inventory changes, using the median price of comparable diamonds - not an average - so a single outlier listing can't skew the number.
Can I find a ring setting for a diamond I find here?
Yes - results include a "Complete the Ring" section with real engagement ring settings sized to fit the diamond you're viewing, with a link to browse the full selection.
Do you sell diamonds directly?
No. The Diamond Price is an independent price-comparison and research platform, not a jewelry store. We don't hold inventory, set prices or process payments - clicking a result takes you to the retailer's own site to complete your purchase there.
