Gemstone Hardness Reference Set – Mohs Scale Mineral Testing Stones

This Gemstone Hardness Reference Set is a practical tool for gemologists, jewelers, goldsmiths, and gemstone collectors who need to identify and compare gemstone hardness. Similar to a Mohs hardness testing kit, this set includes carefully selected natural minerals that represent different hardness levels used in gemstone identification and testing.

The reference set includes minerals such as Epidote, Crystal (Quartz), Garnet, Precious Opal, Chrysoberyl, and Ruby, allowing users to compare hardness and scratch resistance when examining gemstones or mineral samples.

Each mineral specimen represents a different position on the Mohs hardness scale, making this set useful for educational purposes, gemology training, jewelry workshops, and gemstone evaluation.

This hardness reference kit helps professionals and students better understand mineral hardness, gemstone durability, and scratch resistance, making it an excellent tool for gemstone identification and gemological study.

Note: The epidote and garnet specimens are partially cut off, while the remaining minerals are in excellent condition. For this reason, the set is offered at a reduced price.
