One Carat Vow — Sterling Silver 1ct Lab-Grown Diamond Ring

A full carat. Not a fraction of one, dressed up as a carat.

A single one-carat lab-grown diamond, held in a solid sterling silver solitaire — the size people actually mean when they say “a proper ring”.

This is the ring that answers the question before it is asked. One carat is the number every couple hears and remembers, and it is the number most jewellers quietly avoid delivering at a price you can actually pay.

Why it holds its value

The single most important thing about this ring is what it is not: it is not a cluster pretending to be a carat, and it is not a fraction hidden behind photography. It is one stone, one carat. An asset you can hold in one hand.

The details

• Metal — Hallmarked S925 sterling silver
• Stone — Lab-grown diamond, 1.00 ct centre
• Setting — Solitaire
• Certification — Individually numbered; supplied with a certificate of authenticity

What "an investment in love" means here

You are not buying a moment. You are buying the earliest asset of a life you are building together — real silver, real stones, and a number that stays hers. She will wear it when you are both old, and it will still be worth what you paid for it.
