When it comes to choosing the best pick among White Gemstones gemstones, Thomsonite is known to be a popular choice!Physical properties of Thomsonite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Thomsonite Optical Properties are responsible for imparting various physical properties to its structure. Knowledge of these properties is equally important to gem-cutters as well as to consumers. Thomsonite cleavage is nothing but the plane across which the crystal splits during cutting. Thomsonite cleavage is perfect on ; good on ,and specific gravity of Thomsonite is 2.25-2.40.
The physical properties of Thomsonite, in fact, are imparted by the chemical composition of its individual molecule. The reactivity or inertness of the crystal is solely governed by its chemical structure. Chemical composition of Thomsonite is represented by NaCa 2Al 5Si 5O 20 · 6H 2OMichael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
