👉Diamonds are the hardest known natural material, ranking 10 on the Mohs scale of hardness, which measures a material’s ability to resist scratching. 👉Moissanite, a lab-created gemstone, is slightly softer but still very hard at 9.25 on the Mohs scale, making it a durable alternative to diamonds. 👉Cubic zirconia, while visually similar to diamond, is significantly softer, with a Mohs hardness of 8-8.5, making it more prone to scratching over time. . . . #gemstonestudy #gemstonescience #gemsto
