Lab-grown diamond color
Which color?

Many colored lab-grown diamonds, including most pink and red ones, get their color from post-growth treatment. For each colored lab-grown diamond we present, we show you who graded it and what its grading report says about treatment, or tell you it has no grading report, before you choose.

We prefer D to F, but you can ask for a warmer tone (G to J). G to J can show a slight warm tint, which is often hard to see.

Metal for the setting

No size yet? That's normal.

  • Borrow a ring. A ring they already wear on that finger (or the same finger on the other hand) tells us most of what we need. Measure its inside diameter in millimeters, or trace the inside circle on paper with a ruler beside it. After we reply, send a photo of it by replying to our email, or by WhatsApp/text 786-750-5714.
  • Get sized at a local jeweler. Any jeweler can measure a finger in a few minutes; tell us the US size they give you.
  • Size after the proposal. It's made in a best-guess size and resized after. Designs with lab-grown diamonds all the way around the band (full eternity) can't be resized; for those we'll ask you to get sized first.
Grading report (optional)
How quickly do you need options?

A number or a range is fine.
