The Paraiba capsule collection, part of the main Royal line, includes several types of rings. The capsule is based on Paraiba tourmaline, which is usually used to create High Jewelery jewelry. This variety of tourmaline has an interesting feature: the stone does not cast a shadow when light hits it, but a soft blue halo appears around it. It seems that the tourmaline seems to begin to glow. As jewelers explain, the fact is that the stone is so transparent that light passing through it is amplified several times. In addition, this mineral contains traces of gold, which is also extremely rare.
The first to discover the mysterious blue mineral was Heitor Barbose, who in 1987 stumbled upon it off the banks of the Paraiba River in Brazil. Tourmaline was hidden in earth rocks that are more than 500 million years old. The stone contains a large amount of copper and manganese, which are responsible for its unusual glow.
Jewelers from Tiffany & Co. were among the first to appreciate Paraiba tourmaline, which immediately entered into an exclusive contract for the purchase of all stones weighing over 3 carats.
As MIUZ Diamonds notes, Paraiba tourmaline is also interesting from an investment point of view. Since its discovery, the price of tourmaline has increased by 2000%. First of all, the interest of gemstone fans and, therefore, the price is influenced by rarity. Over the decades since the start of mining, only about 50 kg of stone have been found in total, and the Brazilian deposits have already exhausted themselves. Today, the main suppliers of Paraiba tourmaline are Mozambique and Nigeria, the stones from there are almost identical to those from Brazil.
