About Pink Lab Grown Diamonds
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 pink prices to historic highs. A fancy vivid pink of this size in a mined stone would command a seven-figure price. Lab grown technology now makes the magic of a true fancy vivid pink 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 pink hue arises from lattice strain and trace elements (the same mechanism as natural pinks), is locked into the crystal structure, and will never fade.

Frequently Asked Questions
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, VS1 clarity, IGI certified.
What is a three-stone setting?
The marquise pink center is flanked by two shield-cut diamonds — 0.97 carat of side stones in total. The three-stone design is a classic symbol of a couple's past, present, and future, and the crisp white shield sides set off the pink center beautifully.
Why is this ring two-tone?
The center is set in rose gold to warm and enhance the pink diamond's hue, while the band and side-stone settings are white gold for brightness and contrast — a deliberate two-tone pairing that makes both the pink center and the white sides stand out. Two-tone is shown here; your ring is made in the single metal you select — or ask us to recreate the two-tone look.
What metals can I choose?
10K, 14K or 18K solid gold in yellow, white or rose, or platinum. The ring shown is two-tone 14K white gold & 14K rose gold.
Can this ring be resized?
Yes — complimentary resizing within the first year.
How much does this ring cost?
The Margaux starts at $2,250 in 10K solid gold, $2,460 in 14K, and $2,670 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?
Each ring is handcrafted to order in 1–2 weeks, then ships free worldwide with full insurance.
