FINDER: SIZE
Carat size finder
Carat is weight, not size. This finder translates it into millimeters on the finger, drawn to the same scale as a US quarter so your eyes can calibrate.
On-screen size depends on your display; the quarter is there so the ratio stays honest. Figures come from standard proportion tables and shift slightly with each stone’s exact cut.
Three facts that save money
- Diameter grows with the cube root of weight: doubling the carats adds about 26 percent to the visible size, not 100.
- Elongated shapes (oval, emerald, pear) cover more finger per carat than rounds.
- Prices jump at round-number weights; a 0.90 looks like a 1.00 and skips the premium.
