Poland (Amber Gallery Export-Import, Amber Line) and Lithuania (Amber Trip Lithuania) presented this material at the International Jewellery Tokyo (IJT) show in January 2008.It also appeared at the Tucson gem shows in February 2008, where it was sold by amber dealers and distributors under names such as "natural green Caribbean amber" or "very rare Baltic amber" (Pedersen, 2008).This material, which has a peridot-like bright greenish yellow to green color, displays a distinctive deeper green component than previously seen in amber, even in the rare green material from Mexico.Author AA visited Treasure Green Amber Ltd. in June 2007 and was provided with information on the material by general manager Hung Chi and sales manager Steven Wai.They stated that their "green amber" is obtained from natural amber-allegedly of Brazilian, Baltic, or other origin-that has been treated by a two-stage procedure involving long time intervals under controlled heat, pressure, and atmosphere, in an autoclave developed in Germany for heat treatment.
