About Blue Lab Grown Diamonds
Fancy blue diamonds are among the rarest colored diamonds on earth — the Hope Diamond, the Cullinan Blue, and the Oppenheimer Blue have all set auction records at $30M–$50M+ apiece. Natural blue diamonds owe their color to trace boron in the crystal lattice, and only a tiny fraction of mined diamonds show true blue saturation. Lab grown technology makes the romance of a true blue diamond accessible without the financial or ethical burden.
Mohana's blue lab grown diamonds are chemically, optically, and physically identical to mined blue diamonds — graded by the same IGI and GIA laboratories using the same scales. The boron-tinted color is part of the diamond's atomic structure, not a surface treatment, and will not fade.
Blue diamonds pair most beautifully with white gold or platinum settings, which amplify the cool blue tone. For warm contrast, choose yellow gold. Explore the full blue diamond collection.
Frequently Asked Questions
Are blue lab grown diamonds real diamonds?
Yes. Lab grown blue diamonds are 100% real diamonds — same crystal structure, same hardness (10 on the Mohs scale), same optical brilliance as mined blue diamonds. Every Mohana blue diamond is certified by IGI or GIA.
How many side stones does this ring have?
Two complementary side stones (often trapezoid, pear, or trillion — ~0.5–1.8 ct each, varies by design). 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 blue lab grown diamond engagement ring cost?
The Mohana starts at $3699.00 in 10K solid gold and scales up with 14K, 18K, and platinum. A natural mined blue diamond of comparable size and saturation would cost $300,000 to $3M+.
Will the blue color fade over time?
No. The boron-tinted color in a lab grown blue diamond is part of the diamond's atomic structure, 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.
