Why Sizing Matters More for Meteorite Rings
Most gold or platinum rings can be resized by any jeweler — the metal is heated, stretched or compressed, and refinished. This is not possible with meteorite rings. The meteorite inlay is cut to fit a specific ring channel. Changing the ring size would require removing the inlay, altering the metal, and re-cutting new meteorite to fit the new dimensions — essentially making a new ring.
This means you need to get your size right before you order. There is no quick fix after the fact.
The Tools You Need
Do not estimate your size based on a ring you already own — ring diameters vary by manufacturer and the measurement may be off. Use a proper ring sizer: a set of graduated metal rings, typically in quarter-size increments from size 4 to 14, that you physically try on your finger.
A custom ring sizer from Jewelry by Johan ($10) is designed specifically for this purpose and provides the most accurate pre-order measurement. Given that you are investing in a ring you will wear for decades, this $10 step is not optional — it is the smartest part of the buying process.
When to Measure
Finger size changes throughout the day and across seasons. Measure under these conditions for the most accurate reading:
Measure at the end of the day. Fingers are typically at their largest in the evening, after you have been active. A ring sized to your morning finger may be tight by afternoon.
Measure when your hands are warm. Cold causes fingers to contract; warmth causes them to expand. Size to your typical active temperature, not first thing in the morning in winter.
Do not measure immediately after exercise if your exercise significantly increases hand swelling — wait 30 minutes.
Consider the season. If you are ordering in winter for a summer wedding, your fingers will likely be larger in summer. Err toward the larger estimate.
Width Affects Fit
A narrower ring sits differently on the finger than a wider ring. A 4mm band slides over the knuckle easily and settles into the finger groove comfortably. An 8mm or 10mm band has to accommodate more of the knuckle width, which means it fits more snugly at the knuckle and may feel tighter than the same numbered size in a narrower width.
The rule of thumb: If you are ordering a ring 8mm or wider, consider sizing up by a quarter or half size from your standard size. The ring should slide over your knuckle with moderate effort — not slide freely, but not require force either.
When in doubt, size up slightly rather than down. A ring that is slightly loose is an inconvenience; a ring that is too tight to wear is unwearable.
Measuring a Finger That Needs an Unusual Size
If your knuckle is significantly wider than your finger base (this is common), you face a tension: the ring needs to be large enough to go over the knuckle but small enough not to spin freely once seated.
For this situation, there are a few options. First, size to the knuckle and accept some spinning — a comfort-fit (rounded interior) ring will minimize this. Second, discuss the situation with your jeweler — some designs incorporate sizing beads or tension features on the interior that reduce spinning while allowing the ring to clear the knuckle.
International Size Conversions
Jewelry by Johan uses the US standard ring sizing scale. If you have a European, UK, or Japanese ring size, conversion charts are readily available — but verify your converted size with a physical sizer before ordering, since conversion charts can vary by manufacturer.
What Happens If the Size Is Wrong
If your ring arrives and the fit is noticeably wrong — not "slightly different from what I expected" but genuinely unwearable — contact Jewelry by Johan immediately. In cases where the ring size does not match the ordered specification, the workshop will address it. In cases where the customer's measurement was the source of the discrepancy, a remake fee applies.
This is another reason the custom ring sizer ($10) is worth every cent. It is the documentation that the size was accurately measured before the ring was made.
One precise measurement prevents a lifetime of wearing an uncomfortable ring. Take the time.
