{"product_id":"12565238","title":"Ethiopian Paraiba Tourmaline Loose Stone 0.715ct (CuO: 1.989%, MnO: 0.555%)","description":"\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003eThis is Ethiopian Paraiba tourmaline, sourced in Hong Kong. For this purchase, I did not focus solely on clarity; instead, I selected stones that embody the vivid blue and neon glow characteristic of Paraiba tourmaline. Ethiopian Paraiba tourmaline has been gaining significant attention since August 2026, when it was officially recognized as a new source by both the GIA (Gemological Institute of America) and the Gübelin Gem Lab.\u003cbr\u003e\u003cbr\u003eA defining characteristic of Ethiopian specimens is their unique chemical composition; some contain copper levels comparable to those from Brazil, and they also tend to have relatively high concentrations of vanadium (V), gallium (Ga), and lead (Pb). The vanadium content, in particular, serves as a crucial indicator for distinguishing these stones from those known to come from Brazil, Nigeria, and Mozambique.\u003cbr\u003eBecause I want you to appreciate not just the gemstone itself but also its chemical makeup, I have included data from an energy-dispersive X-ray fluorescence (ED-XRF) analysis.\u003cbr\u003eWhile only the CuO (copper oxide) and MnO (manganese oxide) values are displayed on the product page, a variety of other elements were examined during the actual analysis.\u003cbr\u003eI hope you will enjoy the unique personality of this stone by comparing the physical Paraiba tourmaline you receive with its analysis data to see what elements it contains.\u003cbr\u003e※ ED-XRF (Energy Dispersive X-ray Fluorescence) is an analytical method that exposes a gemstone to X-rays to determine the types and quantities of elements contained within it.\u003cbr\u003e※ Some elements have been hidden in the analysis data posted on the product page.
