- Aventurine Quartz - Aventurine quartz is a variety of quartz that contains small sparkling mineral inclusions, typically of mica or hematite. The inclusions give the stone a shimmering or glittering effect, making it a popular choice for jewellery. It is found in various colours, including green, blue, brown, and red, with green being the most common. The green colour is due to the presence of fuchsite, a type of mica.
In jewellery making, aventurine quartz is often used for beads, pendants, and cabochons. It can be cut into various shapes and sizes and can be polished to a high shine. Aventurine quartz is also popular in tumbled stone form for use in necklaces, bracelets, and other jewellery. - Carat - A carat (abbreviated "ct") is a unit of measurement used to describe the weight of a diamond or other gemstone, and separately is a unit of measurement used to describe the weight of precious metals such as gold,.
For gemstones, one carat is equal to 0.2 grams or 200 milligrams. The weight of a diamond is one of the Four Cs (along with cut, colour, and clarity) that are used to determine a diamond's value.
It is important to note that a diamond's weight does not necessarily correspond to its size. A diamond's cut, which affects how well it reflects light, can make a diamond of a lower weight appear larger than a diamond of a higher weight. Additionally, the carat is not the only factor to determine the value of a diamond, other factors such as clarity, colour and cut are important too.
In the gold industry, the purity of gold is measured in carats (abbreviated "ct"), with 24 karats being pure gold and lower carat numbers indicating a lower purity level. So, for example, 18 carat gold is 18/24 or 75% pure gold, and 12 carat gold is 12/24 or 50% pure gold.
