Interweave had 2 good articles today, this one being on types of Australian opals, and it includes information on the sugaring treatment, but apparently the author doesn't know that opalholics isn't a hyphenated word.

Meet the Gemstones: Outback Opals – Boulder, Koroit, and Andamooka Opal
October 26, 2018 | Author: Sharon Elaine Thompson



"With colors that seem to appear magically from the depths of the stone, one of the most fascinating gemstones, without question, has to be opal. Even opal-holics, though, know that opals with a white body color can leave something to be desired, even when the play of color is strong. If the same flashes of color are seen against a dark background, they are much more dramatic.
