Round vs oval at 1 carat
| Shape | Median price | Listings (n) |
|---|---|---|
| Round | $350 | 26,340 |
| Oval | $400 | 16,976 |
Shape rows apply the same 30-listing-per-retailer minimum within each shape, so together they can pool slightly fewer listings than the all-shapes headline when a retailer clears the minimum overall but not in one shape.
Monthly price history
| Month | Pooled median | Listings (n) | Retailers |
|---|---|---|---|
| April 2026 | $645 | 54,651 | 6 |
| May 2026 | $680 | 69,480 | 6 |
| June 2026 | $249 | 45,404 | 6 |
| July 2026 | $360 | 43,326 | 6 |
Each month pools only retailers with at least 30 qualifying listings that month (the same rule as the headline figures above), so the July 2026 row matches this page's headline.
Coverage note. June 2026 was a partial collection cycle for Ritani; June rows pool fewer Ritani listings than adjacent months.
Composition caveat. Monthly medians reflect the mix of stones listed each month as well as pricing: inventory shifts (which retailers listed what) move these numbers alongside true price changes. Month-to-month moves here are directional context, not a price series.
Stat definition. Figures on this page pool all qualifying listings in the stated carat range: all colors, clarities, and cut grades, from retailers with at least 30 qualifying listings. The monthly Index benchmark is a different, tighter statistic (E VS1 round Excellent-cut IGI). The two are not comparable and should not be quoted against each other.
Loose stones only. Every figure on this page is for a loose lab grown diamond as listed, before any ring setting. No blended ring-total pricing appears on this page; setting costs vary by retailer and are never merged into these comparisons.
How current are these prices?
Every price on this page was captured from public retailer listings on July 23, 2026 (July 2026 collection cycle) and is accurate as of that date only. Retailers reprice and delist stones continuously, so any listing shown here may have sold, been delisted, or changed price since capture.
