Every ring in this store is one of a kind and was made at one size — and inlay can't be resized — so the size on the listing is the size of the exact ring in the photographs, and getting your measurement right before you order is the whole game. This page is how to do that, and what happens if it goes wrong anyway.
How to get your size
The reliable way: get measured. Any piercing studio or jeweler can size a finger in a couple of minutes, and it costs nothing but the trip. Tell them two things: the finger the ring is for, and the width of the band you're considering — because width changes the answer, below.
The honest warnings about shortcuts:
- A size taken from a thin ring you already own is a starting guess, not a measurement. Bands of different widths sit differently on the same finger.
- Paper strips, string, and printed charts measure the tool as much as the finger. If you use one, treat the result as approximate and confirm it against a real sizer before ordering a ring that can't be resized.
- Fingers change size over a day — warmer and later usually means slightly larger. If you're between readings, get measured at the time of day you'd normally wear the ring.
Why width matters
A wide band contacts more of the finger, so it wears tighter than a narrow band at the same marked size. The store's current piece is 8 mm wide — wide enough that the difference is real. If your known size comes from a narrow band, expect a wide band to feel snug at that same number, and be measured with a wide band in mind rather than assuming your usual size transfers. This is the single most common way a one-of-a-kind ring order goes wrong, and it is entirely preventable in two minutes at a studio.

Why there is no resize to fall back on
An inlay band is a full circle of set sections — stone, coral, and opal fitted and bonded into a metal core, then shaped and polished flush. There is no plain section to cut, and the inlay materials cannot stretch or compress to a new circumference. It is not a service the store declines to offer; the construction doesn't allow it. The full reasoning is its own journal post: “Why a one-of-a-kind inlay ring can't be resized.” The materials reference states it the same way: Materials & Inlay.
What happens if the size is wrong
First, the route this store prefers: if you're not sure of your size, get measured before you order. The ring isn't going anywhere until it sells, and it can't be resized — so there is no reason to guess, and every reason to walk into a studio first.
If a wrong size is ordered anyway, you're not stuck with it. Contact the store, and the ring can be exchanged for another available piece of equal or greater value (you pay any difference) — or, when a comparable piece can be made, remade at shared cost, at the store's discretion. What the store cannot do is resize the ring itself: the construction doesn't allow it, which is exactly why the exchange and the shared-cost remake exist. The refund policy states the same terms: refund policy.
Questions buyers ask about sizing
How do I know my ring size?
Get measured at a studio or jeweler — two minutes, and it's the only method this page fully trusts. Tell them the finger and the band width. A size from a thin ring you own is a guess; paper and string are approximations.
Does band width change my size?
It changes how a size fits. A wide band — the current piece is 8 mm — wears snugger than a narrow band at the same number. Be measured with width in mind.
Can the ring be resized if it's close?
No. Not close, not a half size, not by a little — full-band inlay has no plain section to work on. The journal post explains why in full: “Why a one-of-a-kind inlay ring can't be resized.”
What if I order the wrong size?
Contact the store. The ring can be exchanged for another available piece of equal or greater value (you pay any difference), or — when a comparable piece can be made — remade at shared cost, at the store's discretion. It can't be resized; the exchange and the shared-cost remake are what's offered instead.
