Outstanding micro faceted teardrops  of "All Natural", the absolute finest, Turkish blue chalcedony, that possess the sought after ghostly glow of blue/lavender, measure  at a sizable 18mm with incredible luster, unlike the treated chalcedony you see today that fade or change color in time.  
 
These beauties are complimented by equally fine, natural purple African amethyst cushions with all solid 14k gold metal components at an overall length of 1.75".
