Sterling Silver, faceted brown diamond slices, natural surface Astrophyllite.  1-1/2" long from the post.  PLEASE LOOK AT THE VIDEO FOR MORE DETAIL!  These earrings are just earthy and wonderful! The diamonds at the top sparkle, as do the astophyllite. Astrophyllite is a rare, hydrous potassium iron titanium silicate mineral, typically found in brown to golden-yellow hues. Its name comes from the Greek words "astron" (star) and "phyllon" (leaf), referring to its characteristic starburst crystal patterns and micaceous cleavage.  They dangle from textured tops that are made by fusing tiny bits of sterling, then hammering and rolling.  EXCHANGES ONLY PLEASE.
