A good necklace works every day. It sits right at the collarbone, catches light without asking for attention, and wears cleanly under a shirt. That is how we design every Riyanika diamond necklace.

The collection

For everyday, our solitaire pendants and pendant necklaces are the most-worn pieces we make. For occasions and gifts, look at tennis necklaces and station necklaces where diamonds run evenly along the chain. For layering, our layering chains and bar necklaces sit beautifully together.

Lab-grown or natural

Both diamond types come GIA-certified. Lab-grown diamond necklaces give you a larger centre stone for less. Natural diamond necklaces hold their value longer and carry the tradition of a mined stone.

Chain length guide

16 inches sits at the base of the neck (choker). 18 inches is the most common and hits just below the collarbone. This is our default. 20 inches falls to the top of the sternum. 22 inches is a longer, more dramatic drop. Every necklace ships with an adjustable or multi-loop chain unless stated.

18K gold, three colours

Yellow, white and rose 18K solid gold. All hallmarked. The chain and the pendant are made from the same karat gold so there is no colour mismatch over time.

Frequently Asked Questions

What length necklace should I buy?

18 inches is the default for most women. It sits just below the collarbone and works with crew necks, v-necks and open collars. Choose 16 inches for a choker look, 20-22 inches for longer pendants and layering.

Are Riyanika necklaces solid gold or plated?

Every necklace is 18K solid gold, both the chain and the pendant. We do not do plated or vermeil. All pieces are hallmarked.

Can I shower or swim with a diamond necklace?

You can shower with it but we don't recommend swimming. Chlorine weakens gold alloys over time and salt water can dull the diamond setting. Take it off before the pool.

What's the difference between a pendant and a solitaire necklace?

A solitaire has one diamond, usually set in a prong or bezel. A pendant can be any shape. Heart, cross, initial, halo, cluster. Solitaire is more formal; pendants tend to be more personal.

How do I clean a diamond necklace?

Warm water, a drop of mild washing-up liquid, and a soft toothbrush around the setting. Rinse and pat dry with a lint-free cloth. Once a year, send it to us for a professional ultrasonic clean. Free for life.

Do your necklaces come with a gift box?

Yes. Every piece ships in a signature Riyanika box with a ribbon. If you are sending a gift directly, add a gift note at checkout.
