Madagascar Blue Star Sapphire 3.25 carats 9x7.2x4.5mm
Denim blue color, sharp star nice high dome. Seems like yesterday you could find star sapphires like this at any of the major gem shows......not anymore. I just love the color(like a worn denim blue) and the character of the Madagascar stars. .
When I first started collecting star sapphires back in the late 1980's, Madagascar Blue Star Sapphires always intrgued me. I love the variety of denim blue colors, the distinct star effect, and the relative low cost you could find them for. You could typically find them at a gem show in Tucson or Bangkok for $10-20/carat.
Nowdays though even finding them is a task, most you see that look like them are artificially colored or artificially enhanced with a star and finding the untreated ones are near impossible.
