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 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.

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, 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 metals can I choose?
10K, 14K or 18K solid gold in yellow, white or rose, or platinum. The ring shown is 14K white gold.
Can this ring be resized?
Yes — complimentary resizing within the first year.
