Gemstone Hardness - How durable is your gemstone?

5/7/2019· Gemstone hardness is one of the primary factors when making this comprehensive determination of wearability. For example, gemstones such as opal (Mohs 5.5 - 6.5), moonstone (Mohs 6 - 6.5) and pearl (2.5 - 4.5), are considered to have poor wearbility and should, therefore, be worn in earrings and pendants. If you have your heart set on wearing a
