Greetings, My name is Matthew, and I am the owner of the Chautauqua Jeweler, located in Jamestown New York. I am having a bit of trouble locating a reputable heat Treatment facility that can enhance the color of Aquamarine. If anybody knows a safe and reputable establishment that offers this service, please contact me with information about the location and possible pricing. Thank you all so very much.
unless this is a very costly stone, you could probably do the heat treating yourself. Put the stone in a test tube and heat it with an open flame, watching for a color change. If the stone doesn’t have significant inclusions, it shouldn’t shatter on heating. Most stones are heated after faceting. -royjohn
