Compare
A natural diamond necklace is the piece of jewellery most likely to be passed down. It sits close to the neck, it gets worn for the biggest moments, and it holds its value better than almost anything else you can put around your collarbone.
Solitaire pendants
The natural diamond pendant necklace is the most classic piece in the category. 1 ct is the most popular, 0.50 ct is the subtle everyday choice, and 2 ct starts to become an occasion piece.
Tennis necklaces
A natural diamond tennis necklace is the single most dramatic piece in our collection , 10 to 25 total carat weight of matched diamonds around the neck. It is the anniversary-milestone piece, the generational heirloom, the piece that becomes the centrepiece of a jewellery box.
Stations and layering
Station necklaces space a small number of natural diamonds along a fine chain for a more subtle effect. Layering chains work alongside a pendant and a watch for a modern, lived-in look.
Provenance
Every natural diamond on the collection is Kimberley Process certified and GIA-graded. The supply chain is auditable back to the mine. We include the certificate with every piece.
Bespoke
The necklace category is where bespoke requests most often come in. Customers want a specific centre stone in a specific pendant design. Start your bespoke natural diamond necklace.
Frequently Asked Questions
What size natural diamond pendant should I buy?
1 ct is our most popular size. Visible, elegant, not ostentatious. 0.50 ct is a good subtle everyday piece. 2 ct starts to become a statement piece. For a wedding gift, 1-1.5 ct is the sweet spot.
How much does a natural diamond tennis necklace cost?
Our natural diamond tennis necklaces start at around $15,000 for 10 tcw and rise to $80,000+ for 25 tcw. This is the highest-value category we sell. Typically milestone anniversary or 50th-birthday purchases.
Are natural diamond necklaces a good investment?
A GIA-certified natural diamond over 1 ct generally holds 40-60% of retail on the secondary market, better than most fine jewellery categories. Rare coloured diamonds have historically appreciated.
What chain length should I choose?
18 inches is the default. Sits just below the collarbone. 16 inches is choker-like. 20-22 inches drops lower and layers well with shorter chains.
How do I clean a natural diamond necklace?
Warm water, mild soap, soft toothbrush around the pendant and clasp. Bring it in annually for professional cleaning. Free for life on all Riyanika pieces.
Can I upgrade my natural diamond pendant later?
Yes. Our lifetime upgrade programme lets you trade in any Riyanika piece and put 100% of its purchase price toward a more expensive one.
