Retailer prices are difficult to compare when one store highlights a sale, another shows a crossed-out list price, and their search results use different quality grades. We compare live inventory instead. Each jeweler gets one benchmark at each carat weight, so Ritani's much larger and often cheaper catalog cannot pull the combined market figure down simply by containing more diamonds.
Current price comparison
These are loose-diamond prices before a ring setting or other jewelry is added. Each figure represents the typical price among up to five of that jeweler's least-expensive qualifying diamonds, rather than one unusually cheap listing.
| Jeweler | 1 carat | 2 carats | 3 carats | Diamonds meeting our rules |
|---|---|---|---|---|
| Brilliant Earth | $510 | $1,340 | $2,350 | 829 |
| Ritani | $228 | $457 | $721 | 1,831 |
| With Clarity | $379 | $868 | $1,317 | 3,307 |
What today's comparison shows
- 1-carat diamonds: Ritani has the lowest current benchmark at $228. The highest benchmark in this comparison is $510 at Brilliant Earth.
- 2-carat diamonds: Ritani has the lowest current benchmark at $457. The highest benchmark in this comparison is $1,340 at Brilliant Earth.
- 3-carat diamonds: Ritani has the lowest current benchmark at $721. The highest benchmark in this comparison is $2,350 at Brilliant Earth.
A lower benchmark does not automatically make a jeweler the better choice. Ring designs, inspection tools, customer support, returns, warranties, and how an individual diamond looks can justify paying more. Use this table to understand the starting price, then compare the complete purchase.
Diamonds included in the comparison
- Round lab-grown diamonds close to one, two, or three carats
- D–H color and VS2–VVS1 clarity
- Strong cut grades
- IGI or GIA grading reports
- Current, in-stock inventory checked within the freshness limit
Why the numbers can differ
Two diamonds with the same headline grades may have different proportions, measurements, fluorescence, growth characteristics, or visible details. Retailers also differ in pricing strategy and service. The table is therefore a consistent shopping benchmark, not a claim that every diamond at one store costs less.
Why we do not average every listing together
Ritani has an unusually large inventory and frequently sets the lowest benchmark in our checks. Averaging every listing from every jeweler would allow that one catalog to dominate the result. Instead, we first calculate one price for each jeweler and then compare the jewelers equally. This keeps the retailer table useful without confusing inventory size with the wider market.
How to use this comparison
Start with the price difference at your preferred carat weight. Then inspect the grading report, measurements, video, return policy, and complete ring price. Our diamond finder can surface current matches, while the market report shows how the combined multi-jeweler benchmark is moving over time.
The two reports answer different questions: this page compares jewelers on the latest common date; the market report follows the seller-balanced price over time.
