18K Solid Gold Marquise Diamond Prong Chain Necklace

At Riyanika Jewels, we take pride in offering high-quality fine jewelry crafted in 18K Solid Gold, adorned with both Natural and Lab-Grown Diamonds. To ensure complete transparency and peace of mind, every piece of jewelry is accompanied by trusted certifications that verify its authenticity and quality.

Gold Certification

All our jewelry is crafted in 18K Solid Gold and comes with the official BIS Hallmark, a government-recognized certification that guarantees the purity and authenticity of gold. This ensures that every piece you own is not only elegant but also genuine in its gold quality.

Lab-Grown Solitaire Jewelry

Our lab-grown diamond jewelry is certified by the International Gemological Institute (IGI). Each certificate verifies the diamond’s authenticity, along with detailed grading of cut, clarity, color, and carat weight—ensuring you receive a diamond of the highest standard.

Gemstone Jewelry

Every gemstone piece is accompanied by a detailed Gemologist Report, offering an in-depth analysis of the stone’s unique characteristics. Additionally, gemstone jewelry is certified by YGA (Your Gemologist Association) for added assurance of authenticity and quality.

Optional Certification: Customers may also request certification from globally recognized institutions such as IGI or GIA. Please note that this service requires an additional fee and may take 30–40 days for processing.

At Riyanika Jewels, every piece is crafted with love in 18K Solid Gold, adorned with Natural and Lab-Grown Diamonds. To keep your jewelry looking as radiant as the day you received it, follow these simple care tips:

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 18K Solid Gold Natural and Lab-Grown Diamond Jewelry will remain stunning for years to come.
