Diamond fluorescence is one of the most misunderstood characteristics in the diamond world. Some shoppers avoid it, others seek it out—but most don't really understand what it is. Let's clear that up. What Is Diamond Fluorescence? Fluorescence is the visible light some diamonds emit when exposed to ultraviolet (UV) rays. About 25-35% of diamonds exhibit some degree of fluorescence, and in almost all cases, the color is blue. Fluorescence Grades None: No visible fluorescence under UV light Faint: Barely detectable...

Moissanite has become a popular diamond alternative—but how does it really compare? Here's an honest, side-by-side look at both stones. What Is Moissanite? Moissanite is a gemstone made of silicon carbide, originally discovered in a meteor crater in 1893 by Dr. Henri Moissan. Today's moissanite is lab-created and designed specifically for jewelry. Key Differences Sparkle & Fire Moissanite actually has MORE fire (rainbow flashes) than diamond. Its refractive index is 2.65-2.69 vs. diamond's 2.42. This creates a "disco ball" effect—beautiful...

Lab-grown diamonds have revolutionized the jewelry industry. But are they right for you? Here's everything you need to know to make an informed decision. The Bottom Line (TL;DR) Lab-grown diamonds are real diamonds—chemically, physically, and optically identical to natural diamonds. The only difference is origin. They cost 50-70% less than natural diamonds of equivalent quality. What Are Lab-Grown Diamonds? Lab-grown diamonds (also called lab-created, synthetic, or cultured diamonds) are created in controlled laboratory environments using advanced technology that replicates the...
