Are Crystals Better Than Diamonds. When they were first discovered 120 years ago these beautiful clear or sometimes green or yellow stones were mistaken for diamonds. Thermal conductivity is higher for diamonds than many other crystals.
Similarly diamonds are good conductors of heat whereas crystals are poor conductors of heat. Cubic zirconia has a much lower refractive index than a diamond so it captures light differently and shines less. This means that Moissanite is noticeably much sparklier and displays more prismatic fire than a diamond which is noticeable even to an untrained observer.
Every stone has pros and cons but a diamond is almost always the preferred gem for an engagement ring.
Pair with a diamond halo for added sparkle. Crystals are a non-renewable resource. Natural hexagonal quartz crystals differ greatly from natural octagonal isometric diamond crystals. This means that Moissanite is noticeably much sparklier and displays more prismatic fire than a diamond which is noticeable even to an untrained observer.
