About Fancy Yellow Lab Grown Diamonds
Natural Fancy Yellow diamonds of this size are rare and highly collectible, especially in unusual fancy cuts. Lab grown technology now makes that same warm yellow attainable in a large, clean stone.
Mohana's fancy yellow lab grown diamonds are chemically, optically, and physically identical to mined yellow diamonds — graded by the same IGI and GIA laboratories. The yellow comes from nitrogen within the crystal lattice (the same mechanism as natural yellow diamonds), is permanent, and will never fade. This stone is IGI certified — verify its grades directly on the IGI portal.

Frequently Asked Questions
Are fancy yellow lab grown diamonds real diamonds?
Yes. Lab grown yellow diamonds are 100% real diamonds — same crystal structure, same hardness (10 on the Mohs scale), same optical brilliance as mined diamonds. This centre stone is a Fancy Yellow, VVS2 clarity, IGI certified.
What is a heptagonal step cut?
It's a rare, geometric fancy cut — a multi-sided outline with long, parallel step facets (like an emerald cut, but with an unusual angular silhouette). It gives clean, mirror-like flashes rather than sparkle, and makes for a genuinely distinctive stone.
What metals can I choose?
10K, 14K or 18K solid gold in yellow, white or rose, or platinum. The ring shown is 14K yellow gold.
Can this ring be resized?
Yes — complimentary resizing within the first year.
How much does this ring cost?
The Ines starts at $6,450 in 10K solid gold, $6,660 in 14K, and $6,870 in 18K gold or platinum.
What's included with my ring?
The IGI® grading report, a signed Mohana certificate of authenticity, free worldwide insured shipping, a lifetime craftsmanship warranty, and a 30-day return window.
How long does it take to make and ship?
