Anyone looking to invest in a piece of Tanzanite jewelry must have come across terms such as carat weight, grading, and cut among others. These factors are commonly associated with all types of gemstones as they are used to estimate their value, but what do they actually mean when it comes to size? If you are looking to acquire your first Tanzanite jewelry then you must understand the specifics associated with Tanzanite value per carat.
A gem's carat weight is usually among the first factors buyers take into account when selecting a precious stone as it is directly influential on its price. It is a measurement unit used in gemology to represent the weight and is usually abbreviated to cts (carats) or ctw (carat weight) for reference. When a jeweler refers to a gem of one carat, he is actually referring to a stone of 200 milligrams or 0.00705 oz.
Each carat is usually separated into 100 points to ensure a precise measurement. For example, a Tanzanite weighing o.5 carat is referred to as a ‘half-carat’ or a ‘fifty-pointer’ and equals 100 milligrams. The Tanzanite value per carat tends to be higher for larger blue stones as they are now increasingly rare compared to their smaller counterparts.
Now that the meaning has been clarified, let’s look further into what size actually means in terms of carats for our Tanzanite stones. While carat refers to how much a gem weighs, it does not automatically give you much information about the size of your stone.
Size is about the dimensions of the jewel which are dependent on its height, its surface diameter, and the type of cut selected.

We do this by following set guidelines for our gemstones based on the different types of cuts available, namely Heart, Marquise, Octagon, Oval, Pear, Round, and Trilliant, our gemstones usually hold the following carats per dimension.

As large Tanzanites with significant weights are usually hard to come by, carat and size are important factors dictating the value of a Tanzanite. However, they are not the only variables to take into account when estimating and selecting a Tanzanite gemstone. Other elements such as color, clarity, and the rating of the cut will affect the value of the stones.
Gems of intense blue or violet color are usually worth more than pale Tanzanites. Similarly, a stone with excellent clarity or very few noticeable blemishes is considered to have a significantly greater value than those with eye-visible inclusions. By combining all these ingredients, you can ensure that you invest in a Tanzanite gemstone that both fits your expectations and your budget.
