Condition
In good condition. The diamonds are approximately G-H color, VS clarity. The light yellowish green sapphire is soft, moderately saturated, and lightly included, the blue-violet sapphire is bright, moderately saturated and slightly included with some small chips along the facet junctions, the medium-light pinkish orange sapphire is moderately included with a few crystals present near the girdle, the bluish green sapphire is lightly saturated and slightly included, the pink sapphire is a nicely saturated bright hue and moderately included, with a few crystals visible only under magnification. The medium greenish brown stone is eye clean with the exception of abrasions to the facet junctions; a refractive index could not be obtained, preventing its confirmation as a sapphire. The enamel and rock crystal are intact.
