Madagascar Blue Star Sapphire 3.30 carats 8.4x6.6x5mm
Sharp star on this little dazzler from Madagascar. Nice deep blue body and high dome as well
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.
