Natural Diamond Engagement Ring

A natural diamond engagement ring carries the weight of tradition. The stone is a billion years old. It was mined, cut and graded before we set it in 18K solid gold in our workshop. If provenance, rarity and long-term value matter to you, this is the collection.

Settings

A solitaire setting is the cleanest way to showcase a natural diamond. One stone, a simple band, nothing else. A halo frames the centre stone with smaller diamonds and makes it look larger. A three stone ring is symbolic and timeless. A side stone design flanks the centre with complementary diamonds along the band.

Shapes

Round brilliant is the classic and the most forgiving on finger shape. Oval elongates the finger. Emerald and Asscher cuts have a cleaner, vintage feel. Pear, marquise and cushion each carry their own signature. Browse by round, oval, emerald, or pear.

Frequently Asked Questions

What carat size should I get for a natural diamond engagement ring?

The US average is 1 ct. At Riyanika, most customers buy between 0.75 ct and 1.5 ct when choosing natural. Anything above 2 ct is a statement piece.

How much does a natural diamond engagement ring cost?

Our natural diamond engagement rings start at around $2,500 for a 0.50 ct solitaire and rise to $30,000+ for a 3 ct halo. Price scales sharply above 1 ct because large, high-clarity natural stones are genuinely rare.

Are your natural diamonds conflict-free?

Yes. Every stone is Kimberley Process certified and sourced through audited suppliers with full chain-of-custody documentation back to the mine.

What's the difference between the 4Cs. Cut, colour, clarity, carat?

Cut is how well the diamond is faceted (affects sparkle). Colour is how white it is (D-F is the top tier). Clarity is how clean it is internally (VS1-VS2 is the sweet spot). Carat is weight. Cut matters most for visual impact.

Do natural diamond engagement rings come with insurance?

We provide a formal appraisal with every ring over $1,000 for your insurance provider. We do not sell the insurance itself , Jewellers Mutual in the US and T H March in the UK are both reliable.

How long will a natural diamond engagement ring last?

A lifetime, with basic care. Diamond is the hardest natural material on earth. The 18K gold setting will need a prong check every 2-3 years, which we do free of charge.
