Swarovski ring size guide
Swarovski uses its own whole-number ring labels, which are not the same as EU circumference sizes. The official chart maps Swarovski 55 to a 17.2 mm inner diameter and US 6¾ (about US 7 on a half-size chart).
How Swarovski sizing works
Use Swarovski’s official chart for its brand labels: Swarovski 52 is US 5¾, 55 is US 6¾ and 58 is US 8. Confirm with the brand guide because these labels must not be read as EU circumference values.
