How to Measure?

Take a piece of string or a soft measuring tape and drape it around your neck at the length you'd like the necklace to sit. Mark the spot, then measure it against a ruler in inches.

What if I'm between lengths?

Go with the longer length for a more relaxed drape, or the shorter one for a snug fit. Our 16" and 18" lengths are the most versatile and suit most necklines.

Never Take It Off

Shower, swim, sweat. Our 18K gold plating is vacuum-bonded to surgical-grade steel, so it won't lift, fade, or react to water.

Gold that stays gold

10x stronger gold plating with PVD coating means no fading and no green marks. Built for years of daily wear, and backed by our 2-year warranty.

MADE FOR YOU

Every piece is made to order with the name, initials, or birthstones you choose. Nothing sits on a shelf waiting. It's made when you order it, for you.

The Olivia Quality Promise

Every Olivia piece is built to be worn on repeat — not saved for "someday." Our 18K gold plating is 10x thicker than the industry standard, layered over surgical grade stainless steel with PVD coating. No copper. No brass. No lead. Just gold that stays gold.

That's why every piece is waterproof, tarnish-free, and safe for sensitive skin. Shower in it. Sleep in it. Never take it off. And if anything ever goes wrong, our 2-year warranty has you covered.
