Paraiba tourmaline is considered one of the "world's three rarest gemstones," and high-quality stones are said to be far more valuable than diamonds of the same size. This new type of tourmaline was first discovered in 1987 at the Batalha mine in Paraiba, Brazil. The mine was depleted and closed within a few years, making it a phantom gemstone. In recent years, mines have been found outside of Brazil, but the quality of Brazilian stones is particularly highly regarded. This item is being sold to organize a collection. It is a very delicate and simple Paraiba tourmaline ring. The main stone is a small Paraiba tourmaline, but it has a good green color and is characteristic of Brazilian stones. It has the unique inclusions of Paraiba and a viscous green color. I think it's a ring that's easy to wear layered or as a first Paraiba. Please note that the color may appear different depending on the light. Also, although not noticeable to the naked eye, there may be unique inclusions, cracks, and scratches due to the natural stone. Basically, there are no noticeable scratches, but I will sell it to someone who understands that it is a used item. No price reduction. Ring only for sale.
