A banded form of quartz covered in unique and distinctive patterns.<\/p>\n\n\n\n A semi-opaque stone that was used extensively by the Egyptians. It is known as ‘the stone of courage’ and is said to have received its name from the female Amazonian warriors who worshiped the moon goddess, Diana. It allegedly got its name after being discovered near the Amazon River.<\/p>\n\n\n\n A translucent, fossilised resin that comes in a range of colours including yellows, reds, whites, blacks and blues. When rubbed, amber produces static electricity. The best quality amber is clear.<\/p>\n\n\n\n One of the most popular gemstones, which has long been considered valuable. Amethysts range in colour from light to dark purple; the deeper purple stones are considered to be the finest.<\/p>\n\n\n\n A transparent light blue or sea-green gemstone. Today, blue aquamarines are more highly valued, but this was not always the case. Large aquamarines are relatively common and the best ones come from Brazil.<\/p>\n\n\n\n A dark green variety of chalcedony that is splattered with reddish-brown spots that resemble blood. The extent of the marking varies depending on the stone. Spots are favoured over larger stripes and markings.<\/p>\n\n\n\n The red, orange, or amber variety of Chalcedony. It is often a solid colour, but banded examples also occur, in which case it is jointly classified as both agate and carnelian. Carnelian once held greater value than it does today.<\/p>\n\n\n\n A family of minerals that is often milky to grey to bluish in colour.<\/p>\n\n\n\n Ranges from a light, minty-green to a deep apple-green and is a green version of chalcedony. The unique, rich colour of chrysoprase derives from its origins, in nickel-rich areas.<\/p>\n\n\n\n A hard stone that ranges in colour from yellow to brown to green. Alexandrite and cat\u2019s eye are both notable types of chrysoberyl.<\/p>\n\n\n\n Citrine (from the French for ‘lemon’) is a rare, yellow type of quartz, a semi-precious stone that ranges in colour from pale yellow to orange to golden brown. The best quality citrine is found in Brazil.<\/p>\n\n\n\n An organic gem, consisting mostly of calcium carbonate, deposited by tiny sea creatures called polyps living in the depths of warm seas in huge colonies. It grows in branches that look like underwater trees. Coral is believed to be one of the oldest forms of gemstone jewellery, with some pieces dating back as far as 23,000 BC.<\/p>\n\n\n\n A precious, lustrous gemstone made of highly compressed carbon. Diamonds are one of the hardest materials known to mankind. Colours of diamonds range from colourless, yellow, orange and brown to almost black. Natural coloured (or \u2018fancy\u2019) diamonds can be extremely rare. The cut, colour, clarity and carat weight of a diamond are the criteria jewellers use to discern a stone\u2019s value.<\/p>\n\n\n\n One of the four ‘precious’ stones. An intense, deep green is the most desirable colour for emeralds. Flaws and cloudiness (‘jardin\u2019) are very common in emeralds, so stones are often oiled and dyed to improve their look. Synthetic emeralds have fewer imperfections and are hard to set apart from natural stones. Emeralds belong to the beryl group of stones, which form as large, six-sided crystals. Emeralds were long thought to have healing powers, especially for eyesight.<\/p>\n\n\n\n Describes a group of several closely related minerals. Garnets come in a variety of colours, including green, however the most common colour is dark red. In descriptions, \u2018garnet\u2019 tends to refer to dark red stones unless otherwise specified.<\/p>\n\n\n\n A semi-precious stone that ranges in colour. Translucent jade is more highly valued than opaque jade. Jade is often cabochon cut. Stones with imperfections are usually carved. Two different minerals are known as jade: jadeite and nephrite. The Chinese have prized jade for thousands of years and regard it as having medicinal properties when worn or ingested as a powder.<\/p>\n\n\n\nAmazonite<\/h2>\n\n\n\n
