Pink diamonds are among the rarest gems on Earth. The legendary Argyle mine in Western Australia — source of over 90% of the world's natural pinks — closed in 2020, sending natural fancy-pink prices to historic highs. A natural fancy vivid pink of this size would command an extraordinary premium. Lab grown technology now makes the magic of a true fancy-color diamond accessible.

Mohana's pink lab grown diamonds are chemically, optically, and physically identical to mined pink diamonds — graded by the same IGI and GIA laboratories. The color arises from lattice strain (the same mechanism as natural pinks), is locked into the crystal structure, and will never fade.

What does "ready to ship" mean?

This is a finished, in-stock ring (Design No. R25131) — 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 pink lab grown diamonds real diamonds?

Yes. Lab grown pink diamonds are 100% real diamonds — same crystal structure, same hardness (10 on the Mohs scale), same optical brilliance as mined pink diamonds. This center stone is a Fancy Vivid Pink, VVS2 clarity, IGI certified.

What is a half-moon side stone?

A half-moon (or demi-lune) is a diamond cut with one straight edge and one curved edge, like a half-circle. The straight edge sits against the center stone so the side diamonds hug the oval closely, framing it without distraction.

What is a three-stone setting?

The oval pink center is flanked by two half-moon white diamonds — 1.50 carat of side stones in total. The three-stone design is a classic symbol of a couple's past, present, and future.

What metal is this ring?

14K White Gold. This is a single, fixed-metal piece — there is no metal, color, or stone selection. The only choice you make is your ring size.

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?

$3,960 — one price for any size. No tiered or per-metal pricing.

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 until it ships?

Your ring is resized and dispatched within 5 business days of your order, then ships free worldwide with full insurance.
