The beauty of a diamond is best unleashed through its cut. That's why we perfected ours. At Hearts On Fire, we source the most pristine diamonds on earth and cut them for extraordinary sparkle. The result? Rare, beautiful diamonds whose brilliance is matched only by the women who wear them.We hand select only high-quality, transparent, and knot-free natural diamond crystals. Diamonds that meet these rigorous standards are rare. So rare that only 1/10 of 1% of the world’s rough diamond crystals can become a Hearts On Fire diamond. A blend of art and science, the Hearts On Fire cut was designed to let in as much light as possible for an exceptional sparkle that’s impossible to miss. Our proprietary cutting formula highlights a diamond’s physical properties—like the way it reflects and refracts light—and emphasizes its inherent beauty with precise angles that show it off to its most magnificent effect.
