What Moves the Price
Carat weight moves it most. Price scales with stone size faster than with any other choice, which is why the same design can span several multiples of its starting price across the carat range.
Metal is second. Sterling silver and 14k gold sit at the accessible end, 18k gold above them, platinum at the top. The metal changes the mounting price, not the stone.
Setting style is third. A plain solitaire mounts one stone; halos and pavé bands add melee diamonds and labour. At equal carat, expect a halo or three-stone design to start roughly $100–$200 above a solitaire, which the table above reflects.
Shape matters least at the same weight. Fancy shapes can carry slightly different per-carat pricing, but the effect is small next to carat, metal and setting.
For market context rather than our prices: per-carat, lab-grown diamonds sold for 72.8% less than natural diamonds in 2025, up from 26.6% in 2019, per the lab-grown vs natural report by BriteCo, a jewelry insurer that underwrites both stone types.

How These Numbers Are Measured
This index is generated from the complete Beyond Carat catalogue, not a sample: for each category we take the lowest configured price among all its designs at their default carat weight, on the date shown at the top. It is re-measured monthly. Figures are floors, not averages — a typical purchase in each category lands above its floor once carat and metal choices are made. Where this page and a product page disagree, the product page is right.
Price Questions, Answered
Measured across the full catalogue as of August 2026: engagement rings start at $749 at default carat weight (935 designs), with solitaires from $749, side-stone rings from $749, halos from $849 and three-stone rings from $949. Anniversary rings start at $331 and eternity bands at $179. The configurator reprices live as you change carat, metal and options, so the product page always shows the exact figure for your build.
Growing gem-grade diamond in a reactor costs far less than mining it, and that gap has widened every year: per-carat, lab-grown sold for 72.8% less than natural in 2025, up from 26.6% in 2019, per a report by the jewelry insurer BriteCo. The stones themselves are chemically and optically diamond — the discount reflects production economics, not quality.
Carat weight, by a wide margin — price scales with stone size faster than with anything else. Metal is second: silver and 14k gold sit below 18k, and platinum sits above it. Setting style is third: a plain solitaire costs less than a halo or pavé band at the same stone size. Shape moves price the least at the same carat weight.
Beyond Carat studs start at $269 at default carat weight. Of the 829 stud designs in the catalogue, 229 are under $500 and 603 are under $1,000 as configured at their default carat, so most of the range sits in everyday-gift territory. Hoops start at $279 and fashion earrings at $329.
They are measured floors, not promises. Each figure is the lowest configured price in that category at its default carat weight on the date shown at the top of this page, re-measured monthly against the live catalogue. The price on a product page always wins over anything printed here.
