Diamond Price Tracker (May 2026)
Independent monthly tracking of natural and lab-grown diamond list prices across the largest online retailers, sampled to a fixed specification basket.
Our team of certified gemologists and jewelry experts provides in-depth analysis to help you make informed purchasing decisions.
We track list prices for a fixed basket of diamond specifications across the largest online jewellery retailers, so you can see at a glance what a comparable stone costs at each. We update the data roughly once a month and keep historical snapshots for trend analysis.
Prices below are the advertised list price in USD at the time of sampling, before any promotional codes. Sampling is manual and reproducible — visit each retailer with the matching specification to verify. Where a retailer had no in-stock match for a basket, the row is left blank rather than substituted.
Read our methodology for how we gather and verify data, and our affiliate disclosure for the commercial relationships behind some of these retailers.

How this data is collected
- We define a fixed specification basket (carat, colour, clarity, cut, shape, origin).
- For each retailer, we search their public inventory for the lowest list price matching the basket, in stock at the time of sampling.
- We record the price, the SKU (or stone ID) where available, and the sample date. Where we use a marketplace median (e.g. Rare Carat) rather than a single SKU, we say so in the notes column.
- If no in-stock match exists, we leave the cell blank rather than substituting a non-matching stone.
- Prior snapshots are retained on this page and in its structured data, so price movement over time stays visible to readers and to search engines.
The Carat Cut earns commissions on some retailer links. Sampling and ranking decisions are independent of those relationships — see our review methodology.
