Tanzanite vs Sapphire. Color happens to be the primary factor when it comes to choosing a gemstone. This is because the color will always win over other parameters as long as the gem will be durable enough for its purpose. One of the well-known gemstone colors that are in demand is the blue sapphires gemstones. However, this article will be looking at two rare gemstones, which are Tanzanite vs sapphire. Additionally, we’ll be looking at how two stones are very different from each other. Tanzanite Tanzanite happens to be a type of zoisite, or better still, the name given to the blue-violet version of zoisite. Note that Zoisite is not extremely rare, but the blue version of Zoisite is. The blue-violet color of Tanzanite can be traced from the amounts of vanadium. Vanadium is a gem that was brought into popularity by Tiffany & Co. However, the name tanzanite was derived from the only country (Tanzania) where the blue-purple version of the gem was found. Sapphire Sapphire happens to be a type of corundum that’s mostly known for its cornflower blue version. This gem can come in any color such as pink, teal, yellow, white, orange, or black. Note that it is the blue version that has become most famous. Though red is the only color you won’t find for sapphire gems, those are always classified as rubies. Tanzanite vs Sapphire Tanzanite with Genuine Diamond Pendant | Source: Amazon Tanzanite happens to be rarer than sapphire, but it is more affordable when compared. This is because tanzanite is a softer gem that can easily scratch than sapphire, and it is new to the jewelry market. However, tanzanite is also eye-clean, and sapphire gem seems to be at least slightly included even after heat treatment. In body color, tanzanite has slightly more violet, and because the range is very wide, it is always confused with a sapphire except you have one of each to compare. Tanzanite vs Sapphire Price For those who don’t know, tanzanite is one of the rarest gems on earth and happens to be one of the most undervalued when compared to its rarity. Due to its scarcity, it is supposed to be a gem to be sold at a high premium price. But with its price per carat ranging between US$300 and US$600, tanzanite is selling for far less than diamonds. On the other hand, the market price for Sapphires can cost anywhere from $1,000 to $11,000 per carat. However, you'll be able to find good-quality stones at $450 - $1,200 per carat.

Though, it doesn’t come in red, which is sometimes called ruby. Note that high-quality blue sapphire comes in a rich, deep blue color. But tanzanite colors are mainly blue and purple. Though the color of top-quality tanzanite gemstones can equal that of sapphires this makes it difficult to tell difference. The tanzanite happens to be a pleochroic gem, which means that it can display different colors whenever it is viewed from different angles, blue, and violet. But the vivid intense blue is the best and most valuable tanzanite color. Tanzanite vs Sapphire Value As you have read, tanzanite is rarer than sapphire. But the blue sapphire is more popular and in high demand. Also, sapphire is considerably more expensive than the tanzanite gem. The blue sapphire is most times considered a good investment gem, and this is because the prices of colored gemstones increase due to demand. But note that there are synthetic versions of blue sapphire on the market, which are very affordable, but not valued. When it comes to value, tanzanite found on the market is natural. This is because the gemstone has not yet been synthesized successfully. This makes tanzanite a better option if you want the sapphire look but at an affordable price tag. Tanzanite vs Sapphire Engagement Rings When it comes to making an engagement ring with Tanzanite, at 6-6.5/10 on the Mohs Hardness Scale, it's a bad idea. However, if you’re looking for a Tanzanite engagement ring, then search for the Violet Spinel. It is much harder than Tanzanite and would last longer. But sapphire, due to its toughness, can be used for engagement rings. This is because sapphires are great gems for everyday use and that’s why jewelry makers go for it. Another thing is that sapphires cannot easily break when struck.
