The Sagittarius coin is a double-sided 16.9 mm pendant in solid 925 sterling silver. The front carries the Sagittarius figure in relief, the name in polished capitals and the ♐ glyph set in lab-grown diamonds. Turn it over and you find the constellation of Sagittarius as it sits in the sky, its stars flush-set in lab-grown CVD diamonds. One star is different: Kaus Australis, the brightest, holds the Sagittarius birthstone: one natural tanzanite.
