Tanzanite Necklace and Diamonds 18K White Gold

Tanzanite is one of the most fascinating and well-known bluish gemstones in today's gem industry and belongs to the Zoisite mineral group. Not until 1967 that this unbelievably rare gemstone was found at the foothills of Mount Kilimanjaro in Tanzania. Stories have been told and passed down about how a bolt of lightning once set these foothills (Mount Kilimanjaro) ablaze.

Masai herders discovered this violetish blue crystal among the ashes of the scorched land in the aftermath. Soon, this rare gemstone was given the name Tanzanite, named after the country of its origin - Tanzania. This gem is only found in a deep and small area on the mountain's foothills (roughly seven km² in size), making natural Tanzanite a thousand times rarer than diamonds. The stone's rarity, combined with its aesthetic appeal, has contributed to its ever-growing trend among both jewellery designers and consumers.

Although countless myths surround the Tanzanite's birthplace, the truth behind its actual discovery remains a mystery. However, geologists believe that tanzanites are rarely present anywhere else on the planet. It is said that the events that led to its formation around 585 million years ago were so rare that it is virtually impossible to repeat them. Tanzanite is now considered the second most valuable blue gem after sapphire.

On the Mohs scale, Tanzanite has a score of 6 to 7. Fine Tanzanite jewellery is becoming more popular among consumers despite its low rating on the hardness scale. Tanzanite needs proper precautions to be followed to avoid careless wear or impact. Tanzanite also has perfect cleavages, which indicates the gemstone's predilection for chipping or breaking if struck hard enough. Tanzanite is also more prone to cracking due to its sensitivity to sudden temperature changes. However, the jewellery setting and proper care from the owner can significantly reduce the risk of harm.

When determining the value of this gem, colour is essential. The most valuable Tanzanites are those with a deep saturated colour. Natural Tanzanites with deep blue colours make the top of the list, accompanied by bluish-purple and violet-blue. The value of a tanzanite decrease as the saturation level of the hue reduces.
