Frequently Asked Questions

What gold options are available?
Our earrings 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 earrings made with solid gold?
Yes. All Riyanika earrings 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 earrings 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 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.
Do the earrings come as a pair?
Yes. All earrings are sold as a matched pair unless the listing states otherwise.
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.
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.
