About Blue Lab Grown Diamonds
Blue diamonds are among the most coveted natural gems in history. The 45.52-carat Hope Diamond (Smithsonian, ~$200–250M estimated value), the 14.62-carat Oppenheimer Blue (sold for $57.5M, then the most expensive diamond per carat ever auctioned), and the Wittelsbach-Graff Blue are among the most legendary. Natural fancy blue diamonds typically sell for hundreds of thousands per carat. Lab grown technology now makes blue diamonds accessible without that premium.
Mohana's blue lab grown diamonds are chemically, optically, and physically identical to mined blue diamonds — graded by the same IGI and GIA laboratories. The blue color comes from trace boron in the carbon lattice (the same mechanism as in natural blue diamonds, including the Hope), is part of the diamond's atomic structure, and will never fade.
Blue diamonds pair beautifully with white gold and platinum (cool-on-cool, lets the blue read at maximum saturation) or with yellow gold for a striking warm/cool contrast. 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 trapezoid lab grown diamonds — 2.00 ct total weight (1.0 ct each). For exact stone count on your specific configuration, our craft team can confirm before production — contact customer support.
What is the band width of this ring?
The band (around your finger) measures 2.5mm wide. At 2.5mm the band balances the visual weight of a 5-carat center in the three stone setting — slim enough to wear daily, substantial enough to hold the design securely. The band width is consistent across all metal options.
How much does a 5 carat blue lab grown diamond engagement ring cost?
The Mohana Solstice starts at $5950.00 in 10K solid gold. A comparable natural fancy blue 5-carat diamond would cost $1M to $5M+ — if available at all.
Will the blue color fade over time?
No. The blue color in a lab grown blue diamond comes from trace boron in the carbon lattice — part of the diamond's atomic structure, not a treatment. It will not fade.
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. The trapezoid (tapered-baguette) shape of the Solstice's side stones gives the design a sleek, architectural profile.
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.
