Custom 18K Gold Lab Grown Diamond Rings

These rings are made to order in 18K gold, which is 75% pure gold. It gives a warm, rich colour and is the traditional choice for engagement and bridal rings in India.

Designs range from slim rings under half a carat to solitaires over 1.5 carats. Each is set with IGI certified lab grown diamonds and made in your size in 15 to 20 days. Compare with our 14K made to order rings.

Why Choose 18K Gold

  • Richer yellow and rose tones than 14K.
  • The classic purity for engagement rings and heirloom pieces.
  • Strong enough to hold prongs securely for everyday wear.
  • BIS hallmarked for guaranteed purity.

Popular Designs to Make in 18K

Solitaires with a single centre stone, halo rings with a frame of small diamonds, half and full eternity bands, and cluster cocktail rings. Every design can be made in yellow, white or rose gold.

Why Lab Grown Diamonds Are the Smarter Choice

Lab grown diamonds are real diamonds. They have the same carbon crystal structure, the same hardness of 10 on the Mohs scale and the same fire and brilliance as mined diamonds. They cost almost 90% less than natural diamonds of the same grade, so your budget buys a bigger, finer stone. For a clean, bright look we recommend VVS1 or VVS2 clarity.

Frequently Asked Questions

Is 18K gold good for daily wear?

Yes. 18K gold is durable enough for daily wear. If you work with your hands a lot, 14K gold is slightly harder.

Can I make an 18K ring with a bigger diamond?

Many designs can take a larger centre stone. WhatsApp us the design and the size you want, and we will confirm.

Can I return a made-to-order ring?

Made-to-order pieces are made for you, so they cannot be returned or exchanged. Please check your size and details before ordering.
