Natural London Blue Topaz Necklace in Sterling Silver

Where a length option is offered it is listed above. As a guide, on most people:

16" sits at the base of the throat — a choker length.
18" falls just below the collarbone, and is the length most people choose.
20" sits lower on the chest and layers well over an 18".

Buying a gift and cannot ask? 18" is the safe choice — and if it is not right, exchange it within 14 days.

Every piece here is either 925 sterling silver finished with rhodium, or 14K gold vermeil — real 14K gold over a solid sterling silver core, at the 2.5-micron minimum the US standard requires. No brass, no base metal, in either case. The metal is listed in the selector above, and our Precious Metal Guide explains how each one wears.

Each necklace uses a secure spring-ring or lobster clasp, listed in the description. The chain is solid sterling or vermeil to match the pendant — not a plated filler chain — so it carries the pendant without stretching.

If a clasp or chain ever fails through a manufacturing fault, it is covered by our lifetime warranty.

Warm water, a drop of mild soap and a soft cloth; dry it thoroughly before it goes away. Put it on last — after perfume, lotion and hairspray — and take it off before swimming, showering or exercising.

Store it flat, dry and separately from harder stones. Skip abrasive polishes and silver dips; they are made for untreated metal and will damage a finish. Our Jewelry Care Guide has the full routine.

Yes. Every stone we set is a real gemstone, hand-picked for its colour and clarity and responsibly sourced. You can see exactly which stone you are choosing in the selector above.

Some of our designs use lab-grown stones or moissanite — just as beautiful, harder wearing, and kinder on the budget. Whenever that is the case we say so right in the product description, so you always know exactly what you are getting.
