How are Macrocrystalline- and Cryptocrystalline Quartz Different?
How is Macrocrystalline Quartz different from the Cryptocrystalline Quartz ?
Macrocrystalline Quartz like Amethyst and Rose Quartz are generally transparent-translucent. Clear crystals are so beautiful.
Cryptocrystallines like agates are more often opaque. Agates and Cryptocrystallines can be slightly softer than Macrocrystallines, 6.5 on Moh’s scale rather than a full 7.
Cryptocrystallines have a duller, wax-like luster while Microcrystallines have a shiny, vitreous luster.
Cryptocrystallines have a higher water content as well as other non-quartz ingredients, up to 20% more.
Because the Cryptocrystalline Quartz can include several Non-Quartz minerals, many of these Quartz are considered Rocks.
Macrocrystalline Quartz– like. Amethyst, Citrine, Tigereye, and Smoky Quartz, which are more likely called Gems, Gemstones or “stone due to their Purity, Bling, shine.
Cryptocrystalline Quartz can look like a Coloured Rock or a dirty rock until it is broken, smashed or cut open. Picking one up, the colours get your attention. Check out Agate. Lots of beautiful colours.
