Why 3ct lab grown

The scale you want, with the feeling you refuse to lose.

A three-carat diamond changes the way your ring is seen. It carries weight, distance, presence. Lab-grown lets that scale feel attainable without sacrificing anything that matters: a beautiful center stone, a clear report, and room to invest in a setting worthy of the stone.

Presence3ct scale

Significant from every angle. The scale that makes an engagement ring unforgettable.

ConfidenceIGI report

Documentation you can hold in your hand — clarity before you commit, reassurance long after.

ValueLab grown

Invest where it matters: size, color, clarity, and a setting that honors the stone.

From loose stone to finished ring

Choose the diamond first. Build the ring around it.

A loose diamond puts you in control. Buy it as the stone alone, reserve it for a proposal, or have it set into a custom ArtGold mounting. Solitaire, hidden halo, pavé, cathedral, or something entirely personal — the center stone leads, and the ring is shaped around its exact proportions.

For a 3ct round diamond, the setting changes everything. Basket height, prong style, band width, side profile — each decision shapes how luxurious the finished ring feels. This is where the ArtGold atelier becomes part of your story.
