Round Cut Strong Fluorescence Lab Grown Diamonds

Strong fluorescence can affect some round cut lab grown diamonds by creating a slight milky or oily look, but this effect is not universal. The round brilliant's intense sparkle helps mask mild fluorescence effects more effectively than other shapes. Each strongly fluorescent round should be evaluated individually. Many display perfectly normal brilliance and transparency, while others may show subtle haziness under certain lighting.

Strong fluorescence is neither universally good nor bad for a round cut lab created diamond. It is negative if the stone shows haziness, neutral if transparency is unaffected, and positive if it whitens the face-up color in warmer grades (H through J). The round brilliant's superior light performance gives it the best chance among all shapes of looking normal with strong fluorescence. Individual stone evaluation is the key.

Yes, strong fluorescence can result in lower pricing for a round cut lab grown diamond. If you find a strongly fluorescent round that maintains normal brilliance (no haziness), you get a beautiful diamond at a discount. Combined with the whitening benefit for warmer colors, a clear, non-hazy strongly fluorescent round can represent some of the best value available in the lab diamond market.
