Fancy Diamond Jewelry

Fancy coloured diamonds carry a different kind of presence. The colour is the point, not the sparkle. Lab-grown fancies give you the same saturation at a fraction of the natural price; natural fancies carry investment-grade rarity.

Frequently Asked Questions

What is Riyanika's signature material?

18K solid gold set with GIA-certified natural or lab-grown diamonds. Every piece hallmarked. We do not sell plated, gold-filled, or vermeil jewellery at any price point.

Is every diamond certified?

Every centre diamond over 0.30 ct is GIA-certified. Smaller accent stones ship with a Riyanika quality certificate confirming the 4Cs and origin.

What's your returns policy?

30-day returns on all non-bespoke pieces. Bespoke and engraved pieces are final sale because they are made specifically for the buyer. First ring resize within 60 days is free.

Do you offer lifetime service?

Yes. Professional cleaning, prong checks and polishing are free for life at Riyanika on every piece we make.

Can I trade in or upgrade my piece 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.

Do I need insurance?

Above $1,000, yes. Standard home insurance usually does not fully cover jewellery. Every piece over $1,000 ships with a formal appraisal that your insurer will accept. Jewellers Mutual (US) and T H March (UK) are reliable options.
