Natural Fancy Vivid Yellow diamonds — the deepest, most saturated yellow grade — are exceptionally rare and command extraordinary premiums at auction. Lab grown technology now makes that same vivid canary colour attainable.

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.

What does "ready to ship" mean?

This is a finished, in-stock ring (Design No. R25228) — not made to order. After you order, we resize it to your selected finger size and dispatch it within 5 business days, fully insured. That's faster than our standard made-to-order rings, which take 1–2 weeks.

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 Vivid Yellow, VS2 clarity, IGI certified.

What are the side stones?

Two white tapered-trapezoid step-cut diamonds flank the centre, with additional round white diamonds on the band — 1.97 ct in total. The crisp, colourless step cuts frame and intensify the vivid-yellow radiant.

Why are the prongs a different colour from the band?

The band is 14K white gold and the prongs holding the centre are 14K yellow gold. Warm yellow-gold prongs sit against a yellow diamond and deepen its colour, while the white-gold band keeps the side stones bright and neutral — a deliberate two-tone choice.

Can this ring be resized?

Yes — we resize it to your selected size before it ships, included free. If you need a size that isn't shown in the selector, contact us first and we'll confirm what's possible.

How much does this ring cost?
