Tanzanite carat weight
Like diamonds and other valuable gemstones, tanzanite is graded by weight. A tanzanite’s carat weight is usually a big determining factor for consumers buying tanzanite in South Africa, and other parts of the world, as it has a direct impact on the price. A carat is a unit of measurement equal to 0.2grams (200 milligrams), and refers to the weight of a tanzanite and other gemstones. Large tanzanite is rarely found in nature, so they are more valuable than smaller tanzanite.
Carat weight is a universal, standard measurement of weight that remains the same throughout the world. This means that regardless of where you purchase your tanzanite jewellery creation, the gemstone’s carat weight remains the same, and legible, all over the world.
Carat weight refers to the gemstone’s entire weight, which includes its depth. Two seemingly identical tanzanite gemstones can have different carat weights if they vary in depth. Similarly, carat weight is often mistaken for size. Two tanzanite stones with the same carat weight could be different sizes, face up.
Size depends on each stone’s proportions, and the size of the underside of the stone. A tanzanite gem shallow in depth might, face up, appear larger than a tanzanite of the same carat weight, that has a smaller size face up, and a deeper depth. Although carat weight is a big determining factor when it comes to price, it is not the only one. Two tanzanite gemstones with the same carat weight could significantly vary in price if their colour, clarity and cut grading differs.
