Stunning Loose Green Amethyst Ring Gem 3.30 Carats
Located in Peshawar, PK
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...

Sparkling Natural Ocean Blue 9.63 Carat Zircon from Cambodia
Located in Hua Hin, TH
Natural Ocean Blue Zircon Rare sparkling Blue Zircon is only found at one place in the world at Ratanakiri province in Northeast Cambodia. Blue Zircon in this vivid blue color is very rare indeed. We cherry pick the stones at the mine in Cambodia and only 1% of all Blue Zircon mined have top quality blue color. A miner may find only a handful of these coveted crystals in a year, These Zircons have a color not normally seen in the main market and are extremely rare and out of a pedigree that very few people will ever own or even see. We are specialist in Blue Zircon and have an office in Ratanakiri where we can source all the best stones direct from the miners. Blue zircon is a beautiful and unique gemstone that has been prized for centuries for its striking color and brilliance. In fact, Blue Zircon has a higher refractive index than sapphire and ruby. Along with an impressive fire, it also has a dispersion level nearly as high as the diamond. What the expert says about Ratanakiri Zircon...
