Diamonds
Loose lab-grown diamonds
Every stone is lab-grown, independently graded by IGI, and photographed in our studio. Browse by shape and spec, or send us the one you like — we'll design the setting around it.
Coming soon
Our inventory of loose stones launches in 2026. Want first access? Email hello@lychora.com with the words “loose diamond waitlist” and we'll let you know the moment the first stones go live.
What you'll see at launch
- Eight shapes — round, oval, emerald, cushion, pear, radiant, princess, and marquise, with more added over time.
- Full 4C specifications — every stone listed with carat, color, clarity, and cut grade.
- IGI certification — an independent grading report ships with every diamond and is linked from the listing.
- Honest pricing — what the stone actually costs to grow and finish, plus our margin. No invented “compare at” prices.

Frequently asked
Are these the same as mined diamonds?
Chemically and optically, yes — they're carbon, graded by the same labs (IGI or GIA) against the same 4Cs. The difference is origin: ours are grown in a reactor over a few weeks rather than pulled from the ground.
Will you sell stones standalone, or only set?
Both. Stones can be purchased loose with their IGI report and protective packaging. The custom setting consult is a separate service if you'd like us to set the stone for you.
What's the lead time on a custom setting?
From approved sketch to delivered ring, typically five to seven weeks. We send progress updates and a final inspection photo before shipping.
