Material & Product Care
AtKomma pieces are crafted in solid gold (9k / 18k) and set with lab-grown diamonds. Designed in Shanghai.
How we select every diamond
Every diamond that enters AtKomma must pass four screening criteria:
- Cut — Excellent or Very Good
- Color — D–G, with no color cast under any light
- Clarity — VS2 and above (eye-clean)
- Daily light — still looks good under ordinary indoor light
We believe a piece worth wearing for a long time should look good in everyday light — not only under a spotlight.
Materials
- Solid gold — not plated fashion metal.
- Lab-grown diamonds — same optical properties as mined stones.
- Finishes and exact karat options vary by piece.
Care
- Remove jewellery before swimming, showering, or applying perfume / lotion.
- Store separately to avoid scratches.
- Clean gently with a soft cloth; professional polish as needed.
