These gorgeous old European cut diamonds date back to around 1900 and are set in 14k rose gold eight-prong basket settings. They total a carat weight of about .60, each weighing about .30 carat. They are near colorless H and I grades and VS and SI2 clarity grades. While their basket settings are original, the posts were added later and come with butterfly backings. They may be changed to threaded screw-on backings for extra security if desired. Each measures about 4 millimeters in diameter, for scale.
