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.

Are yellow lab grown diamonds real diamonds?

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.

What is the band width of this ring?

The band (around your finger) measures 3.0mm wide. At 3.0mm the band balances the visual weight of a 3-carat center in the solitaire 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 3 carat yellow lab grown diamond engagement ring cost?

The Mohana Lami starts at $3699.00 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+.

Will the yellow color fade over time?

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.

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 solitaire setting?

A classic solitaire features a single center diamond on a plain band — timeless, and it lets the diamond speak entirely for itself.

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.
