Before you keep reading

Our largest round solitaire pair currently offered is 2 CT, not 3 CT.

This page is still useful for understanding what a 3 ct total actually looks like (see below) and how its price would sit relative to nearby sizes. But Carat Theory does not yet make a round pair at approximately 3 CT total - the closest pair we actually sell today is the Lumière Stud 2 CT (2.02 CT total, verified). The pieces shown further down this page are drawn from our current solitaire collection, not a 3 CT pair.

What 3 ct looks like on the ear

A 3 ct total is about 1.5 ct per stone (~7.4 mm). It reads as bold, unmistakable sparkle - 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 1.5 ct stone carries its own independent IGI certificate.
