They are prong set in high basket settings in sterling silver, with filigreen designs on the side (see pictures). Box clasp with a safety catch. Marked 925 for sterling, what looks like the intials "JC" for the maker and Thailand for the country of origin.
It's in great preworn condition. Free gift box included upon request. This is a real one-of-a-kind piece and the pictures do not show the sparkly nature of the stones, which have an amazing cut. I've taken photos in various lights, but none do these justice.
