These are exceptional Gold Rutilated Quartz pendants measuring 7 x 8 x 27-29mm. Gold Rutilated Quartz is actually gold to reddish quartz stones rutilated with gold wisps, almost like needles. No two of these pendants are alike, but I can assure you they are all equally beautiful. The silver bail has an opening measuring 3.5mm. The silver bail has had a touch of rhodium added to it to prevent rapid tarnishing. We photographed this pendant with some of our leather cord from Leather Cord USA.
