While tanzanite is not as hard as other precious gemstones like emerald or sapphire, the gemstone still offers a decent level of sturdiness that’s enough to withstand the wear and tear of average everyday life. Tanzanite jewelry does require a bit of additional care, but that should not dissuade you from investing in it. Extreme Rarity That Suits Your Eminence Tanzanite is a pretty rare gemstone; in fact, it’s over 1000 times rarer than the hardest substance on earth, diamond. Wearing tanzanite bracelets after being well-informed about the rarity of its centerstone will make you feel nothing short of a queen. Tanzanite is found in only one place on earth, Tanzania, the country where it was discovered. As per a local Tanzanian geologist, the gemstone’s available supply in hand might deplete within a few decades. It’s about time you got yourself a tanzanite jewelry piece.
