Fancy Yellow Lab Grown Diamonds
Fancy yellow lab grown diamonds are a practical entry point into the fancy color market, combining distinctive color with strong availability and competitive wholesale pricing. Their yellow hue develops during crystal growth as nitrogen becomes incorporated into the diamond structure, making the color part of the stone rather than something added afterward.
Since 2018, OCS Diamond has stocked fancy yellow lab grown diamonds across a broad range of carat weights, shapes, and color intensities, with inventory refreshed every 2 days. As GJEPC and Surat Diamond Bourse members, we focus on documented sourcing, independent certification, and consistent supply for retailers and jewelry manufacturers.
Our selection ranges from Fancy Light Yellow through Fancy Vivid Yellow, giving buyers flexibility across different designs, price points, and volume requirements.
How Yellow Color Forms
During crystal growth, nitrogen atoms present in the growth chamber incorporate into the diamond’s carbon lattice. In HPHT growth, this happens naturally as an inherent part of the process; in CVD growth, nitrogen can be deliberately introduced into the gas mixture to achieve the same result. Either way, no post-growth treatment is needed — the color is part of the crystal from the moment it finishes growing, which is why yellow certificates typically state “as-grown” origin rather than listing a treatment.
What Determines Fancy Yellow Pricing
Fancy yellow lab grown diamond pricing is influenced primarily by color intensity, carat weight, clarity, shape, and overall cut quality. Fancy Vivid Yellow stones generally command a stronger premium than Fancy Light or standard Fancy Yellow because of their deeper and more noticeable color.
Larger stones can also carry higher per-carat pricing, while higher clarity and well-executed cuts can further increase value. For buyers purchasing matched stones or larger quantities, consistency in color intensity, shape, and specifications is particularly important.
Because the category offers a broad range of specifications, retailers can select stones that match both their design requirements and target price points.

Where Fancy Yellow Diamonds Are Most Commonly Used
Yellow sees the widest range of application of any fancy color — solitaire engagement rings, halo settings, and increasingly as melee accents surrounding a white center stone for a warm contrast effect. Its accessible pricing also makes it a common choice for larger statement pieces (2ct+) where blue or pink at the same size would be cost-prohibitive for most retail buyers.
Why Buyers Choose Fancy Yellow

For retailers and jewelry manufacturers, fancy yellow lab grown diamonds offer flexibility across designs, sizes, and price points. The broad selection makes it easier to build yellow-diamond collections, source stones for larger statement pieces, and maintain consistent specifications across multi-stone orders.
Each listed stone includes its certificate and video, while bulk buyers and first-time customers can request a live video walkthrough to review available stones before placing an order.
