Loose Amethyst Color: Light Green Weight: 3.30 Carats Dimension: 8.6x8.5x7.2 Mm Origin: Brazil Certificate: On Customer Demand . Green amethyst, also known as "prasiolite," is a captivating gemstone that belongs to the quartz family. It's cherished for its delicate green hue, which ranges from pale mint to deep olive, and is the result of heat treatment applied to certain varieties of amethyst. This process converts the purple color of amethyst into the enchanting green that prasiolite is known for. The color of green amethyst can be influenced by factors such as the intensity of heat treatment and the original quality of the amethyst. Its serene and calming green shades make it a sought-after gemstone for jewelry, adding a unique touch to rings, earrings, pendants, and bracelets. Green amethyst is known for its transparency and is often cut into various shapes, including emerald cuts, cushions, rounds, and ovals, to showcase its brilliance and color. With a hardness of 7 on the Mohs scale, it's suitable for everyday wear, although some care should be taken to prevent exposure to extreme heat or direct sunlight. While prasiolite is a popular term for green amethyst, some gem experts argue that the name is misleading, as it might imply that it's a separate mineral from amethyst. Nevertheless, the name prasiolite is widely used and recognized within the gemstone and jewelry industry. Metaphysically, green amethyst is associated with healing, balance, and spiritual growth. It's believed to promote emotional stability and connection with nature. Some practitioners of crystal healing value prasiolite for its ability to cleanse and recharge the energy of the wearer. When considering purchasing green amethyst jewelry...
