Yellow is the most common fancy color among natural diamonds — but true vivid yellow saturation is exceptionally rare and historically prized. The 128-carat Tiffany Yellow Diamond (mined in South Africa, 1877), the 110-carat Sun-Drop (a Fancy Vivid Yellow that sold for $10.9M in 2011), and the 101-carat Allnatt Diamond are among the most famous fancy yellows ever cut. Lab grown technology makes the warmth of a true fancy yellow diamond accessible without the natural-diamond premium.
Mohana's yellow lab grown diamonds are chemically, optically, and physically identical to mined yellow diamonds — graded by the same IGI and GIA laboratories using the same scales. The yellow color comes from trace nitrogen in the carbon lattice (the same mechanism as in natural yellow diamonds), is part of the diamond's atomic structure, and will not fade.
Yellow diamonds pair beautifully with white gold or platinum settings, where the cool metal makes the yellow saturation pop with maximum contrast. For a warmer, more traditional look, choose yellow gold — a classic pairing that echoes the diamond's hue. Explore the full yellow diamond collection.
Yes. Lab grown yellow diamonds are 100% real diamonds — same crystal structure, same hardness (10 on the Mohs scale), same optical brilliance as mined yellow diamonds. Every Mohana yellow diamond is certified by IGI or GIA.
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.
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.
The Mohana starts at $3800.00 in 10K solid gold and scales up with 14K, 18K, and platinum. A natural mined fancy vivid yellow diamond of comparable size would cost $30,000 to $200,000+.
No. The yellow color in a lab grown yellow diamond comes from trace nitrogen in the carbon lattice — part of the diamond's atomic structure, 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 three-stone setting flanks the center diamond with two complementary side stones — often symbolizing past, present, and future.
