The origin of blue sapphire

Although you will find sapphire in different colors, it is the blue sapphire that has become commonly associated with this gem. This September birthstone is one of the most popular gemstones used in jewelry for centuries. In ancient times, it was believed to represent the heavens.  In the Middle Ages, blue sapphire was associated with fidelity and chastity, and was often given as a gift to newlyweds. It is prized for its beauty and rarity, as it is found only in a variety of locations around the world, including Sri Lanka, Madagascar, and Australia. Even today, it is still a desired choice for engagement rings and other fine jewelry.

Tanzanite is a beautiful blue stone that was first discovered in the Mererani Hills of Tanzania in 1967. Since then, it has become one of the most sought-after gemstones on the market. The stone is named after its country of origin, and Tanzania is still the only place in the world where it can be found. As a result, tanzanite is relatively rare. It is typically found in shades of blue, violet, and purple. But it is highly desired for its striking blue color. Today, it is commonly used in pendants, earrings, and engagement rings. Though it is a recent finding in the history of colored gemstones, tanzanite has already been appointed as the December birthstone, and is sure to be cherished for years to come.

What is the color difference between blue sapphire and tanzanite?

Sometimes, tanzanite is mistaken for blue sapphire. If their colors are similar, how can you tell the difference between these two blue beauties? For starters, tanzanite has more violet hues than blue sapphire, which tends to be a purer blue. In addition, the stones will have a different appearance when set in metal. Tanzanite goes best with silver or white gold, making it ideal if you want trendy modern jewelry. Blue sapphire goes best with yellow gold, and would be perfect if you have a taste for vintage-style jewelry.

But your efforts will be rewarded in the end. The next time you’re admiring a piece of jewelry with a blue gemstone, chances are good that it’s a sapphire or a tanzanite. It explains why it came with a pretty price tag.

This means that sapphire is less likely to scratch or chip than tanzanite. In addition, sapphires have a higher melting point than tanzanite and can withstand higher temperatures.

So, if you’re looking for a durable and sparkling gemstone, blue sapphire is the way to go!
