Moissanite and diamonds are both stunning gemstones, but they differ in their composition and origin. Moissanite is a synthetic gemstone, while diamonds are naturally occurring. This difference often leads to significant price variations. Understanding these distinctions is crucial for making informed decisions when choosing a gemstone. One key difference lies in their hardness. Diamonds are renowned for their exceptional hardness, ranking at 10 on the Mohs scale. Moissanite, while incredibly durable, boasts a hardness of 9.25 on the Mohs scale. This difference in hardness translates to different levels of resistance to scratching and abrasion. Beyond hardness, the brilliance and fire of moissanite and diamonds also differ. Diamonds are known for their exceptional brilliance and fire, which is a result of their unique crystal structure. Moissanite, while possessing a remarkable brilliance, often exhibits a slightly different fire, which can be a matter of personal preference. Ultimately, the choice between moissanite and diamond depends on individual preferences and budget.
