Ethiopian Paraiba Tourmaline 0.430ct Loose Stone (CuO: 2.334%, MnO: 0.642%) with GIA & Chemical Analysis Reports

Paraiba tourmaline is captivating for its vivid blue to green hues. Characterized by its unique coloration created by the presence of copper, it was first discovered in the state of Paraíba, Brazil, in the 1980s. Since then, copper-bearing tourmaline has also been produced in Africa, and in recent years, stones from Ethiopia have garnered significant attention.

This is an Ethiopian Paraiba tourmaline sourced in Hong Kong. For this selection, rather than pursuing transparency alone, I chose stones that capture the vivid blue-green color and neon effect typical of Paraiba tourmaline.
While inclusions are visible, stones of a similar color with higher transparency can fetch more than three times the price locally. This stone was selected with a focus on balancing beauty of color and price.
Chemical analysis results show 2.334% CuO (copper oxide) and 0.642% MnO (manganese oxide). This is a loose stone that can be enjoyed not only for its aesthetic beauty but also for the elements that create its color. It comes with a GIA report and the chemical analysis data we obtained.
