Frequently Asked Questions

What gold options are available?
Our necklaces are available in 14K and 18K solid gold in yellow, white, or rose gold. 18K is our signature; 14K offers the same designs at a more accessible price.
Are these necklaces made with solid gold?
Yes. All Riyanika necklaces are made with solid 14K or 18K gold — never plated, 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.
Will my necklace come with a diamond certificate?
Yes. Natural diamonds are certified by GIA; lab-grown diamonds are certified by IGI. Certificates are included with your order.
Can I choose the chain length?
Yes. Our necklaces are available in multiple lengths — typically 16", 18", 20", and 22". Select your preferred length when placing your order.
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.
Can I see a design preview before production begins?
Yes. For customized or bespoke pieces we provide a CAD preview before production starts, so you can approve the design first.
