The most striking feature of tanzanite is its multi-faceted color, due to the structure of its crystal formation. As a trichroic gemstone, light enters tanzanite and is divided into three sections of the visible spectrum. Sapphire blue, violet and burgundy are visible from different angles, depending on the lighting conditions. The result is a gemstone that suits a variety of styles, jewelry designs and skin tones.
When mined, tanzanite is often a reddish brown. Through intense heating – up to 400 degrees Celsius – its violet and vivid blue hues are then brought to life. Blue tones are more detectable under fluorescent light, while violet is easily visible under incandescent lights. Larger tanzanite stones are more likely to exhibit richer, more vibrant colors. One bigger gemstone will therefore typically be more valuable than a group of smaller tanzanite stones that are of equal weight.
While there is no standardized grading system for colored gemstones, their value is typically ascertained by their size, color, and clarity. When shopping for a tanzanite gemstone, consider those with very few visible blemishes. Tanzanite gemstones are typically eye-clean, meaning that imperfections are not detectable without magnification. This is true of all tanzanite stones offered by Ritani.
The versatility of tanzanite makes it a stunning choice for pairing with a variety of precious metals and jewelry styles. White metals such as white gold, sterling silver and platinum will highlight its vivid blue tones, while rose and yellow gold will complement any red and burgundy hues.
Every tanzanite offered by Ritani is of the finest quality, hand-selected for its beautiful color. For the best value, we recommend opting for those with medium-light to medium-dark tones, and light to moderate inclusions. These criteria will ensure that your gemstone does not have noticeable blemishes that distract from its stunning hue.
Ritani stands by the quality of each of its gemstones, offering free 30-day returns for all orders. Our certified gemologists are available to help you make the right choice.
To keep your tanzanite gems bright and clean, wash them gently with mild dish soap. Using a soft-bristled toothbrush, clean around the stone and setting to clear away any dust and lint. Avoid strenuous activity when wearing tanzanite jewelry, and request that the gem first be removed if your jewelry is in need of a resize.
