As of August 2026, a complete 2 carat lab-grown diamond engagement ring at Beylora runs $1,800 to $3,900, depending on the design and the metal. Across the wider market, the loose stone alone at the top grades costs more than people expect: about $1,850 for a 2 carat round lab-grown diamond graded D color and VVS2 clarity, and about $2,600 for the same grade as an oval, before any setting.
What actually moves the price
Four things: carat weight, the color and clarity grade of the stone, the metal, and the setting work. Carat moves it most. The grade moves it more than most shoppers realize, which is where pricing gets murky.
The step-down trick to watch for
As of August 2026, a 2 carat round lab-grown diamond graded D color and VVS2 clarity runs about $1,850 loose, while the same size at the common grade of F to G color and VS2 clarity runs about $1,330. At 3 carats the gap widens: about $4,560 for D and VVS2 against $2,320 for the common grade. Most sellers quote you the common grade so the number looks small, and let you climb from there. When you compare two rings, compare the grades in writing, not just the carats.
Why a complete ring can cost less than a loose stone
A brand buys its stones at wholesale, so a complete ring, stone and setting together, can cost less than the same stone bought loose at retail. That is not a trick. It is the difference between buying parts at retail and buying the finished thing from the maker. Every Beylora center stone is a lab-grown diamond graded D color and VVS2 clarity or better, and the complete ring starts at $1,800 at 2 carats and $2,500 at 3 carats.
Before you pay, get three things in writing
The certificate number for the exact stone, so you can look it up yourself. The color, clarity, polish, and symmetry grades. And every fee: return fees, rush fees, resize costs. A seller with good numbers will happily write them down. Before you compare, know what a complete-ring price includes.
