Sadie L Vassil white gold & amethyst vintage ring

This is a beautiful vintage, Sadie L Vassil, genuine 10K white gold and lavender amethyst ring (tested). I received the ring in late '90s and it's been in storage since 2000. Ring is in excellent condition but I would recommend a proper cleaning and polishing. Ring is a size 7 and weighs 4.4 g. Markings on the ring are 10K and the letters SLV. Feel free to ask any questions. Thanks
