How Mohana Compares
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 $3749.00.

About Green Lab Grown Diamonds
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.
Frequently Asked Questions
Are green lab grown diamonds real diamonds?
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.
How many side stones does this ring have?
Two tapered baguette lab grown (6×3×2mm each), 0.75 carat total lab grown diamonds. For exact stone count on your specific configuration, our craft team can confirm before production — contact customer support.
What is the shank width of this ring?
The shank (the band around your finger) measures 3.0mm wide. At 3.0mm the band balances the visual weight of a 3.75-carat center in the three stone setting — slim enough to wear daily, substantial enough to hold the design securely. The shank width is consistent across all metal options.
How much does a 3.75 carat green lab grown diamond engagement ring cost?
The Mohana starts at $3749.00 in 10K solid gold and scales up with 14K, 18K, and platinum. A natural mined green diamond of comparable size and saturation would cost $200,000 to $2M+.
Will the green color fade over time?
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.
Can this ring be resized?
Yes — complimentary resizing within the first year. Full eternity bands are the exception due to their continuous diamond setting.
What is a three stone setting?
A three-stone setting flanks the center diamond with two complementary side stones — often symbolizing past, present, and future.
What's included with my ring?
The IGI® or GIA® grading report, a signed Mohana certificate of authenticity, free worldwide insured shipping, a lifetime craftsmanship warranty, a 30-day return window, and complimentary resizing within the first year.
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.
Can I customize this ring?
Yes — contact our team through customer support to request a custom variation in a different carat, shape, or metal combination.
