No, actually only onyx and chalcedony are sized to my wrist. I have a few more that are sized somewhat (back when they would allow custom sizing), but now they stick to the standard sizing options and will only do a minimum of 16 cm without a battle, and I need 15 cm. The chalcedony took almost the full year from purchase going back-and-forth to get the size I requested! I requested 15 cm, first it came back at 16, I resubmitted and it came back at 17 (!!), OP resubmitted and it came back at 16, then I finally got a bit more pushy and amazingly the last time it came back as 15 finally. The onyx was from about 5 years back and it was no issue at all to get the correct sizing.
