Major retailers rarely stock natural green diamond engagement rings, and when they do, prices start at $10,000–$40,000+ due to the extreme rarity of green diamonds in nature. Mohana delivers IGI/GIA-certified lab grown green diamonds at a fraction of that, handcrafted to your specifications, starting at $2,350 (2 ct, 10K) – $4,970 (5 ct, platinum).

Fancy green diamonds are among the rarest colored diamonds on earth — naturally green diamonds owe their color to millions of years of natural radiation exposure deep in the earth, and only a tiny fraction of mined diamonds show true green saturation. Mined fancy greens routinely sell for hundreds of thousands of dollars per carat. Lab grown technology makes the romance of a true green diamond accessible without the geologic wait or the financial barrier.
Mohana's green lab grown diamonds are chemically, optically, and physically identical to mined green diamonds — graded by the same IGI and GIA laboratories using the same scales. The color is part of the diamond's atomic structure (induced via irradiation color centers), not a surface treatment, and will not fade.
Green diamonds pair most beautifully with yellow gold settings, where the warm gold complements the green saturation — a pairing rooted in the centuries-old tradition of emerald-and-gold jewelry. For a cooler, more modern look, choose white gold or platinum. Explore the full green diamond collection.
Yes. Lab grown green diamonds are 100% real diamonds — same crystal structure, same hardness (10 on the Mohs scale), same optical brilliance as mined green diamonds. Every Mohana green diamond is certified by IGI or GIA.
The shank (the band around your finger) measures 3.0mm wide. At 3.0mm the band is well-proportioned across all 2–5 ct center stone options — slim enough to wear daily while still supporting the solitaire design at the largest size. The shank width is consistent across all metal options.
Pricing varies by carat size and metal: 2 ct from $2,350 · 3 ct from $3,300 · 4 ct from $3,750 · 5 ct from $4,570 (10K solid gold; 14K, 18K, and platinum cost more). A natural mined fancy vivid green diamond of comparable size would cost $30,000 to $200,000+.
No. The color in a lab grown green diamond is part of the diamond's atomic structure (irradiation-induced color centers, just like in nature), not a treatment. It will not fade over a lifetime of wear.
Yes — complimentary resizing within the first year. Full eternity bands are the exception due to their continuous diamond setting.
A classic solitaire features a single center diamond on a plain band — timeless, and it lets the diamond speak entirely for itself.
