Tanzanite is a genuine newcomer to the colored gemstone rings offered at Slate & Tell, so before we discuss this beautiful collection, let’s dive deep into what this vibrant blue gemstone has to offer.
About the Tanzanite Gemstone
Tanzanite has a lustrous fire and brilliance with colors ranging from blue hues to red violets. Our genuine Tanzanite gemstone is found only in one very small part of the world, making it rarer to find than a Diamond. The name Tanzanite originates from where it was discovered back in the 1960s in Tanzania, a small country in Africa.
With so much history behind this beautiful blue and violet gem, many designers, royals like Kate Middleton, and everyday jewelry customers have an eye for it due to its higher value. Tanzanite is a good investment stone, as the natural supply will soon end, thus increasing its rarity and making it even more valuable than other gemstones. It is now being brought back to life with beautifully created Slate & Tell designs made just for you.
