18k Gold Pink Sapphire Ring Size: 7 Weight 4.8g (*green box is just for photo and belongs to a different ring) Purchased from SundayOwl on Etsy Lisa the jeweler who made this piece makes everything herself. From her website: A little about how your ring was made. - - - - - - - - - - - - - - - - - - - - - - - - - - - - Lost wax casting. I begin by creating a wax model of your ring. I then make a mold of it with plaster. After it sets, I place your mold into my kiln for many hours during which the wax is melted out. Next I melt your gold and spin it into the mold using a centrifugal casting machine. It is then quenched in water, there is a mini explosion as the hot flask hits the water and your plaster mold is destroyed. Now for my favorite part, I dig to the bottom of the bucket to find your little gold sculpture. I'm so happy, your ring is ready to be cleaned, textured and finished. This may seem a bit extreme for a simple gold band, but I love the organic softness which is created by wax.
