The 《Diamond Grading Report》 covers unmounted colorless to near-colorless natural loose diamonds and colored diamonds. The 《Jadeite Jade Report》 distinguishes jadeite A, B, C and other imitations. The 《Gemstone Report》is for a loose gem stone, and the gem identification report only issues reports for natural gems (and provides identification of origin, possible man-made places and hot places). The 《Jewelry Report》 contains other types of gem products, suitable for inlaid jewelry, rings, necklaces, bracelets, earrings, brooches... etc. It can identify synthetic materials and imitation gems. The laboratory does not issue reports on rough stones (unprocessed mineral rough stones), and reserves the right not to issue written documents for certain items.
