At Riyanika Jewels, every piece is crafted in solid gold — 18K as our signature, with 14K available across our full catalogue for customers who want a more accessible entry price or everyday-wear durability. Every design ships with certifications that verify the authenticity and quality of both the metal and the stones.
Gold Certification
Every Riyanika piece is solid gold, with the official government-recognized certification that guarantees purity and authenticity — 75% pure gold for 18K, 58.5% pure gold for 14K. Same transparency either way.

Every gemstone piece is accompanied by a detailed Gemologist Report, offering an in-depth analysis of the stone's unique characteristics.
At Riyanika Jewels, every piece is crafted in solid gold — 18K as our signature, or 14K for those who prioritize everyday durability — and set with Natural or Lab-Grown Diamonds. The care guidance below is the same whichever karat you choose.
1. Clean Regularly
Gently clean your jewelry using a mild soap and lukewarm water solution. Use a soft brush to remove dirt, rinse thoroughly, and dry with a soft lint-free cloth.
2. Store Safely
Keep your jewelry in a dry place, ideally in a jewelry box or soft pouch. Store pieces separately to prevent scratches and tangling.
3. Avoid Harsh Chemicals
Remove your jewelry before swimming, bathing, or using cleaning products. Chemicals such as chlorine and detergents can damage both gold and diamonds.
4. Handle with Care
Avoid wearing your jewelry during strenuous activities like exercising, gardening, or heavy lifting. This prevents accidental knocks, scratches, or loosening of stones.
5. Inspect Periodically
Check your jewelry regularly for loose stones or worn settings. If you notice any issues, contact us immediately for professional repair and maintenance.
By following these tips, your Riyanika Solid Gold Natural or Lab-Grown Diamond Jewelry will remain stunning for years to come.
