Phillip Gavreil Sterling Silver and 18kt Yellow Gold Popcorn Pendant Necklace on 18 inch long Adjustable Chain with bezel set 10mm round Garnet. Garnet is the birthstone for January and the stone that celebrates the 2nd anniversary of marriage. The name "garnet" comes from the Latin word "Garanatus", meaning "seedlike", in reference to a pomegranate. This reference makes sense as small garnets look like the bright red seeds you find inside in a pomegranate.
