A tanzanite, like diamonds and other gemstones, has its weight measured in carats. One carat is equal to 200mg, or a fifth of a gram. Carat weight is a universal unit of measurement, and the higher the carat weight, the more valuable the tanzanite. Larger tanzanite weighing more than 5 carats is extremely rare, making it very sought-after and valuable.
The carat weight of a tanzanite indicates the gemstone’s weight or mass, but not its size. The dimensions of a tanzanite (length, width and height) are measured in millimeters and are recorded on the certificate.
Tanzanite comes in various shades of blue and violet, from very pale lavender and medium blue (seen mostly in small stones), to intense deep blue and violet (seen mostly in larger tanzanite). The more vibrant and intense the colour of the tanzanite, the more rare it is, and the higher its value will be. Tanzanite is graded violet dominant to blue dominant, meaning it is more blue or more purple/violet in colour.
