After all, diamonds are expensive, so today I would like to introduce a gemstone that can be used instead. Below are excerpts from my collection. (1) White sapphire Although not as bright as diamond, it is quite hard with a Mohs hardness of 9, so it is often used in rings. (2) Goshenite It is a beryl gemstone, same as emerald. Although it is very beautiful, it is soft with a Mohs hardness of 6, so it may be difficult to make it into a ring. (3) Colorless Topaz With a Mohs hardness of 8, it is the second hardest stone after corundum (sapphire and ruby). It's pretty pretty, so I think it could be used as a ring as well. (4) Zirconia A natural stone is called zircon. Because it is a plain stone, it is not often used for jewelry. However, cubic zirconia, a synthetic stone made by refining zirconium, the main component of this stone, is often used as a diamond substitute because its brilliance resembles the characteristics of diamond. Mohs hardness is 8 to 8.5. 💎 by Secret Jewelry Collection
