July Birthstone- Ruby Crystal Necklace This is the seventh in my Birthstone drop Necklace Series. July - Ruby This necklace has a Swarovski drop on a gold plated chain. I am a believer that less is more. My jewelry is a simplistic form of most of the jewelry that I've seen. I like showing my designs in a small subtle way. The birthstone is a 6 mm Ruby Swarovski drop. The necklace is a 1.3mm silver plated curb chain with a lobster clasp closure. Choose your desired length from the drop down list. This is a section of a poem I found on wikipedia: The glowing ruby shall adorn, Those who in July are born; Then they'll be exempt and free From love's doubts and anxiety. —Gregorian Birthstone Poems
