This is Alchemy's official ring information :
Each ring comes in up to seven different sizes - these sizes are intended as a guide only, and are not strictly an accurate indication of measurement
L = Diameter 16.3mm Circ. 51.24mm US Size 5.75 (small female size)
N = Diameter 17.1mm Circ. 53.72mm US Size 6.75
Q = Diameter 18.3mm Circ. 57.49mm US Size 8
T = Diameter 19.5mm Circ. 61.26mm US Size 9.5
W = Diameter 20.7mm Circ. 65.00mm US Size 11
Y = Diameter 21.5mm Circ. 67.51mm US Size 12 (large male size)
Z - certain styles are a bit bigger again if that option is displayed
How to measure your ring size.
1. Cut a strip of paper no wider than 6mm.
2. Wrap the paper around your finger and mark the paper where it meets.
3. Check that it slips over the joints of the finger without difficulty.
4. Measure the marked length of paper and compare it to the Metric
row in size chart. This should give you a good idea of your ring size.
If your ring falls between sizes, order the smaller one as Alchemy tends to err on the large side.
