When it comes to choosing the perfect stone for your engagement ring or fine jewelry, sparkle is often the deciding factor. Both Moissanite and Lab-Grown Diamonds offer stunning brilliance—but they shine in slightly different ways. While lab-grown diamonds are chemically identical to natural diamonds and offer a classic sparkle, moissanite is known for its fiery, rainbow-like flash that captures attention instantly. In this blog, we’ll explore the differences in brilliance, how each gemstone reflects light, and which one might be right for you based on your style, budget, and sparkle preferences.
