Solid natural stone rings have a slightly wider band than classic rings — we recommend choosing one size larger for comfortable wear.

Sizes in the European scale (finger circumference):

• 9 — 49 mm
• 10 — 50 mm
• 11 — 51 mm
• 12 — 52 mm
• 13 — 53 mm
• 14 — 54 mm
• 15 — 55 mm
• 16 — 56 mm

• 20 — 60 mm
• 21 — 61 mm
• 22 — 62 mm
• 23 — 63 mm

How to measure? Wrap a tailor’s tape or string around your finger at the widest point. Read the millimeters — that’s your circumference. Choose one size larger.
