A natural diamond carries the provenance of a mined stone. Billion-year geological history, Kimberley Process traceability, and the resale floor that comes with a genuine natural. Every Riyanika natural diamond ring is built in 18K solid gold and set with a GIA-graded centre stone.

By purpose

Natural diamond engagement rings are the flagship. Wedding bands and eternity bands are the most-bought companion pieces. Anniversary rings and cocktail rings make the best gift upgrades at milestone years.

By setting

Solitaire for the cleanest showcase of a single natural stone. Halo to make a 1 ct look like 1.5 ct. Three stone for symbolism. Prong for maximum light return. Pavé for extra sparkle along the band.

By shape

Round brilliant is the classic and most forgiving. Oval elongates the finger. Emerald has a vintage, architectural feel. Pear, cushion, and marquise each have their own signature.

Responsible sourcing

Every natural diamond is Kimberley Process certified and conflict-free. Our supply chain is independently audited with full chain-of-custody from mine to finger.

Bespoke

Have a specific natural stone or setting in mind? Design your own ring. We source the stone, render the setting, and build the ring from scratch.

Frequently Asked Questions

What is the difference between a natural and lab-grown diamond ring?

The stone itself. Natural diamonds were formed in the earth over billions of years; lab-grown stones were created in a lab in a few weeks. Both are real diamonds. Natural costs more and holds resale value better.

Are Riyanika natural diamond rings conflict-free?

Yes. Every diamond is Kimberley Process certified. Our suppliers are audited annually and we can trace each stone back to its mine of origin.

How much does a 1 ct natural diamond ring cost?

Our 1 ct natural diamond solitaire engagement rings start at around $5,000 and rise to $12,000 depending on the 4Cs (cut, colour, clarity). A halo setting typically adds $500-$1,500.

What cut grade should I look for?

Excellent or Very Good for round brilliants. For fancy shapes (oval, pear, emerald, etc.), GIA doesn't issue a cut grade but we only stock stones we assess as well-proportioned. Cut matters more for sparkle than colour or clarity.

Do natural diamond rings hold their value?

Better than lab-grown, yes. A GIA-certified natural diamond above 1 ct typically retains 40-60% of retail value on the secondary market. Rare coloured natural diamonds have historically appreciated.

Can I upgrade my natural diamond ring later?

Yes. Our lifetime upgrade programme lets you trade in your Riyanika natural diamond ring and put 100% of its original value toward a more expensive piece.
