What 1 ct looks like on the ear
A 1 ct total is about 0.5 ct per stone (~5.2 mm). It reads as the classic everyday size - seen, but understated - a confident presence that still wears every day.
What to check before you buy
- Cut first - it is what creates the sparkle.
- 14K gold, never plated for an everyday piece.
- The right backing - it should feel secure and comfortable for the specific piece. Push-back vs screw-back.
- IGI certification. E-F colour, VVS clarity. Each 0.5 ct stone carries its own independent IGI certificate.
