Mineralogical Characteristics of Serpentine jade and Thulite gemminerals from Booyo area, South Korea

The mineralogical and gemological characteristics of the two gem minerals: serpentine jade and thulite from Booyo Mine area of South Korea were determined. The study of those minerals were carried out using polarizing microscope for textural study; color set, hardness pencil set and refractometer for determining physical characteristics; X-ray powder diffraction for analyzing crystal structure; XRF, ICP-MS, IR-ray, UV-ray and DTA/TGA analyses for detailed chemistry.
