Sizing is the one part of buying jewelry online that makes people hesitate, especially when it is a gift and you cannot exactly ask. Here is exactly how necklace and bracelet sizing works, and why it matters less than you'd think.

Necklace Length Guide
Necklace lengths are usually grouped into a few standard categories. A choker sits high and close to the neck, typically 14 to 16 inches (35 to 40cm). Princess length falls just below the collarbone, the most common everyday length, around 17 to 19 inches (43 to 48cm). Anything longer starts moving into layering territory.
Gemiria necklaces come in three lengths. Small, 14 inches (35cm), sits high on the collarbone in a choker style. Medium, 16 inches (40cm), is the most popular choice and rests naturally just below the collarbone. Large, 18 inches (45cm), sits lower for a relaxed, layered look. If you are unsure, Medium is the safest default, it is what most people choose and what looks right on the widest range of necklines.
Bracelet Size Guide
To measure your wrist, wrap a tape measure or a strip of paper snugly around it, just below the wrist bone. Then keep one thing in mind: our bracelet sizes are the length of the chain alone. Your nameplate sits in the run of the chain and adds its own width, and every bracelet has a 1.6 inch (4cm) extender, so the finished bracelet is comfortably longer than the number suggests.
The Standard 5 inch (13cm) size gives a closer fit that suits most adult wrists. The Large 6.5 inch (16.5cm) size is roomier and more relaxed, for a broader wrist or a looser feel. Between sizes? Write to info@gemiria.com with your wrist measurement and we will tell you which one to take.
The Extender: Why You Don't Need to Get It Exactly Right
An extender is a short length of chain attached near the clasp that lets you adjust how loose or snug a piece sits, without needing your exact measurement to be perfect. Every Gemiria necklace includes a 2 inch (5cm) extender, and every bracelet includes a 1.6 inch (4cm) extender, built in as standard, not sold separately.
That margin is there on purpose. It means a Medium necklace can sit anywhere from its base length to two inches longer depending on how you clip it, and a bracelet can loosen further for a relaxed fit or tighten up for a snugger one. You are choosing a starting point, not locking yourself into one exact number.
Buying as a Gift, Without Knowing Their Size
If you are buying for someone else and cannot ask without giving it away, go with the most popular option. For a necklace, that is Medium, 16 inches (40cm). For a bracelet, it is the Standard 5 inch (13cm) size, which already allows for the nameplate and the extender and suits most adult wrists. Between the standard sizing and the built-in extender, you have more room for error than sizing usually allows.

Frequently Asked Questions
What necklace length should I choose?
16 inches (40cm) is the most popular length and sits just below the collarbone on most people. Go shorter, 14 inches (35cm), for a choker style that sits higher, or longer, 18 inches (45cm), for a lower, more relaxed drape.
How do I know my bracelet size?
Wrap a tape measure or a strip of paper around your wrist just below the wrist bone. Our sizes are the chain alone, and the nameplate and the 1.6 inch (4cm) extender add to it, so the Standard 5 inch (13cm) size suits most adult wrists and the Large 6.5 inch (16.5cm) size is for a broader wrist or a looser feel.
What does a necklace extender do?
An extender is a small length of chain added near the clasp that lets you adjust how the necklace sits, looser or snugger, without needing an exact size. Every Gemiria necklace includes a 2 inch (5cm) extender for this reason.
Do Gemiria bracelets come with an extender too?
Yes. Every bracelet includes a 1.6 inch (4cm) extender, giving you flexibility on both ends of the size range without needing to measure precisely.
I'm buying this as a gift and don't know their size. What should I do?
Go with the most popular option, the 16 inch (40cm) necklace or the Standard 5 inch (13cm) bracelet, and let the built-in extender absorb the rest. It is designed for exactly this situation.
How long does a custom piece take to arrive?
Every piece is made for you in 7 to 10 days, then delivered free within 1 to 2 weeks.
