Prasiolite, also known as vermarine, is a variety of quartz that is green in color. [68] The green is caused by iron ions. [67] It is a rare mineral in nature and is typically found with amethyst; most "prasiolite" is not natural – it has been artificially produced by heating of amethyst. Since 1950 [ citation needed], almost all natural prasiolite has come from a small Brazilian mine, but it is also seen in Lower Silesia in Poland. Naturally occurring prasiolite is also found in the Thunder Bay area of Canada. [68] Synthetic and artificial treatments [ edit ] A synthetic quartz crystal grown by the hydrothermal method, about 19cm long and weighing about 127 grams The largest documented single crystal of quartz was found near Itapore, Goiaz, Brazil; it measured approximately 6.1m × 1.5m × 1.5m and weighed 39,916 kilograms.

Simpler cuts of Blue Quartz are great for interior decor. Raw slabs and crystals make for excellent focal pieces in your home or office. They become conversation starters that always attract attention! The same effects are said to apply to Blue Quartz. However, it’s more fine-tuned with the calming side of things. In metaphysical healing and color theory, blue tones represent feelings of calm and tranquility. Hale, D. R. (1948). "The Laboratory Growing of Quartz". Science. 107 (2781): 393–394.

Quartz Inclusions: Fluorite
Calcium Fluoride (CaF2) can be found in any colour but when formed within quartz the blue and purple colours are more common. Growing as a cubic material, fluorite usually forms as cubes or octahedrons with strong colour zoning throughout the crystal. a b c d e f g Shigley, J.E.; Laurs, B.M.; Janse, A.J.A.; Elen, S.; Dirlam, D.M.

Quartz with dense, tiny Rutile inclusions that cause a cat's eye effect. Cat's Eye Quartz is not common, and the chatoyant effect is usually weak. Cat's Eye Quartz is usually grayish in color and translucent.Rutile, a titanium oxide (TiO2) forms in the tetragonal crystal system as prismatic needle-like acicular crystals. One of the most common inclusions in quartz. With colours ranging from yellow to brownish-yellow, which are the more common colours, and deep red to brownish-red, which are less common and therefore more desirable. Rutile stars are very sought after. Kihara, K. (1990). "An X-ray study of the temperature dependence of the quartz structure". European Journal of Mineralogy. 2 (1): 63–77.

Blue Quartz ensures that you can be honest and expressive no matter what kinds of adversity you face.

Tridymite and cristobalite have no gem significance; except that the "snowflakes" sometimes found in obsidian are cristobalite. The International Antiques Yearbook. Studio Vista Limited. 1972. p.78. Apart from Prague and Florence, the main Renaissance centre for crystal cutting was Milan. The healing stone won’t take away all the things that make these zodiac signs unique. Instead, it works with their distinct emotional habits to make things a lot more manageable. Conclusion That makes Blue Quartz an obvious stone for Cancer. Emotions drive this sign and they love hard and are naturally sensitive to any darkness that comes their way. The same goes for Scorpios and Pisces.

Its place in the healing world connects to the core mineral and its color. Blue Quartz can help open up your mind and encourage communication and connection with your ethereal guardians. Even in the most chaotic environments, this stone’s healing properties and energy can create a sense of ease in its holder. It’s an instant auric rejuvenator, replacing feelings of anxiety and worry with a wave of peace.McClure, Tess (17 September 2019). "Dark crystals: the brutal reality behind a booming wellness craze".
