44.2% of the certified diamonds in our index appear at two or more retailers simultaneously. We used James Allen as a worked example to show what shared inventory means for the most searched online diamond store and how cross-retailer matching can surface the same stone at a lower price.
Same Diamond, Different Prices
Nearly half the certified diamonds sold online appear at two or more retailers simultaneously. We fingerprint 11.4 million unique stones across 110+ stores to show you the real price spread on the exact diamond you're considering.
Natural Diamonds Dropped 9% and Lab-Grown Didn't Follow
Natural diamond prices fell 9% this week while lab-grown edged up 1.3%. Lab-grown round supply surged 753%, natural pear prices above 2ct dropped nearly 50%, and cross-retailer spreads on lab-grown pears topped 100%.
Fancy Cut Pricing Reality for Pear, Marquise, Heart, Cushion, and Radiant
Cushion lab-grown diamonds trade at an 83.5% discount to natural. Marquise sit at just 78.3%. Five fancy shapes, five entirely different pricing stories for buyers willing to look past the round brilliant.
Lab-Grown Ovals Just Doubled in Price and Most Buyers Haven't Noticed
Lab-grown oval diamonds in the 1.00 to 1.24 carat range at J to K colour and I clarity have more than doubled in price over thirty days, hitting a median of $2,922. Supply surged 127.8% in the same period. That tension can't last, and buyers who chase this spike are going to regret it.
Natural Diamonds Just Got a Lot Cheaper This Week
Natural diamond prices dropped 6.4% this week while lab-grown ticked up 5.6%. Some categories fell over 40%, comparison shopping saves up to 61% on lab-grown rounds, and a handful of exceptional listings are priced well below market. This week's data favours buyers willing to act.
Natural Falls 6% While Lab-Grown Stages a Rebound
Natural diamonds fell 6.4% this week while lab-grown climbed 5.6%, a combined 12 point divergence across nearly 22 million listings. Natural pears and cushions saw the steepest declines, but supply surges in popular categories could push prices lower still.
Why Lab-Grown Wins Bigger on Emerald and Asscher Step Cuts
Natural step cuts carry the steepest clarity premiums in the diamond market, and lab-grown erases them. Emerald cuts now sit 81.0% below natural per carat; asscher sits at 81.7%. The real savings compound deepest in the clarity grades these cuts actually demand.
Lab-Grown Ovals Just Doubled in Price and You Should Be Suspicious
Lab-grown oval prices in the 1 to 1.25 carat range spiked over 84% in seven days, driven by supply composition shifts rather than genuine demand. The smarter play is stepping up in quality or waiting for the correction.
Natural Diamonds Are Down 6% and Some Categories Just Lost Half Their Value
Natural diamonds fell 6.4% this week, but five categories dropped 40% to 82%. Lab-grown prices bounced in select segments, cross-retailer spreads hit 65% on rounds, and we found five stones sitting well below market.
Oval Is the Shape With the Widest Lab vs Natural Gap
Natural ovals carry a median price of $2,346 per carat. Lab-grown ovals sit at $394. That 83.2% gap makes oval one of the widest lab vs natural spreads across any diamond shape, and it exists in the most popular fancy cut on the market.
Natural Diamonds Dropped 6% This Week and Lab-Grown Didn't Follow
Natural diamonds fell 6.4% across 6,077 categories while lab-grown climbed 5.6%. Supply is flooding in for popular engagement ring sizes, cross-retailer spreads remain wide, and several categories cratered by 40% or more.
