Frequently Asked Questions

Can this ring be made in my size?
Yes. We make every ring to order in your preferred size, including sizes not listed on our website. Use our size guide or message us on WhatsApp if you're unsure.
What gold options are available?
Our rings are available in 14K and 18K solid gold in yellow, white, or rose gold. 18K is our signature tier; 14K offers the same designs at a more accessible price.
Is this ring made with solid gold?
Yes. All Riyanika rings are made with solid 14K or 18K gold. We do not use gold-plated, gold-filled, or vermeil.
Can I choose natural or lab-grown diamonds?
Yes. Both options are available. Natural diamonds are GIA certified; lab-grown diamonds are IGI certified. Both are chemically and optically identical — the difference is origin and price.
Can the diamond size or shape be customized?
Yes. We can adjust the carat weight and diamond shape to suit your preference. Share your requirements with us on WhatsApp before placing your order.
Is engraving available?
Yes. We offer complimentary engraving on most rings. Provide your preferred text or initials when placing your order.
Will my ring come with a diamond certificate?
Yes. Natural diamonds are certified by the Gemological Institute of America (GIA); lab-grown diamonds are certified by the International Gemological Institute (IGI). Both certificates are included with your order.
Can I see a design preview before production begins?
Yes. For customized or bespoke pieces we provide a CAD (computer-aided design) preview before production starts, so you can approve the design first.
How long does delivery take?
We offer worldwide free shipping. Orders are usually dispatched within 15–22 business days. Shipping time varies by location but generally ranges from 5–7 business days.
