Gemstone Knowledge of Brazilianite

Brazilianite

Brazilianite

Family: Brazillianite belongs to the Phosphate family of Gemstones.

Country Location: Brazillianite can mostly be found in Minas Gerias, Brazil (hence the gemstone’s name) and New Hampshire, USA (very small deposits have been found here).

Rock Type: Brazillianite can be found in coarse grained igneous rock (known as pegmatites), which are rich in phosphate. This is considered an unusual combination as pegmatites are more known to contain other elements. Feldspar’s and Muscovite are found with Brazillianite.

Hardness: Brazillianite’s hardness measures at 5.5 making it a softer gemstone, preferably used in cocktail jewellery worn infrequently. Brazillianite is considered to be one of the hardest phosphate based minerals, hence why it is the only one considered as a gemstone.

Popular Cuts: Brazillianite can be found using the Cushion and Pendeloque cut, which accentuates colour and brilliance. The most common cut used in the Baguette/Step cut. This not only shows its distinctive colour, but also helps the Brazillianite be more durable. Cutters can make better use out of its fractures and inclusions.

Colour: Brazillianite’s colour ranges from “Chartreuse” yellow, pale yellow to yellow green. This gemstone can also appear as colourless in transmitted light

Lustre: Brazillianite’s lustre is Vitreous

History: Brazillianite is a fairly recent gem, having only been discovered in Brazil in 1944, where it was first thought to be Chrysoberyl.

Folklore: Brazillianite is believed to encourage sociability and the creation of new friendships. It also helps the wearer deal with nerves and bad skin conditions.
