Smoky Quartz Chips - 200g bag

Smoky quartz, a captivating variant of the mineral quartz, possesses a range of physical properties that contribute to its allure and uniqueness. Here are some of its key physical characteristics:

Colour: The most distinguishing feature of smoky quartz is its smoky brown to grey colour, which can vary from pale and translucent to deep and opaque. This colour is a result of natural irradiation and the presence of trace elements within the crystal lattice.

Transparency: Smoky quartz can exhibit varying degrees of transparency, ranging from transparent to translucent. The presence of impurities and inclusions can influence its clarity.

Lustre: Smoky quartz typically displays a vitreous (glassy) lustre when polished, contributing to its gem-like appearance.

Hardness: On the Mohs scale of mineral hardness, smoky quartz has a rating of 7 out of 10. This makes it relatively durable and resistant to scratches, suitable for various jewellery and decorative applications.

Crystal System: Smoky quartz belongs to the trigonal crystal system. Its crystals are often prismatic and hexagonal in shape, with well-defined terminations.

Cleavage: Smoky quartz has no distinct cleavage, meaning it doesn’t break along specific planes like some minerals. Instead, it exhibits a conchoidal fracture, producing curved and smooth surfaces when broken.

Density: The density of smoky quartz varies, but it typically falls within a range of 2.65 to 2.91 grams per cubic centimetre.

Optical Properties: Smoky quartz is a birefringent mineral, meaning that it can split light into two different rays as it passes through the crystal. This property contributes to its interesting optical effects.

Fluorescence: Some smoky quartz specimens may exhibit fluorescence under ultraviolet (UV) light, emitting a glow in various colours.

Each bag has approximately 200 grams (net) of crystal chips.
