Fine silver and aventurine in a luscious dome setting. Your custom size available in US 4-10. A simple yet stunning setting. Ring shown in photo is size US 7.25. (White spots on stone are just reflected light , not actually there.) The aventurine stone is 10mm. What does sustainable green silver mean in my jewelry? I start with fine silver which is the purest available -99.9% silver made with reclaimed/recycled metal or from third party certified, ethically mined metal. Our jewelry is 3 time State of California WRAP Award winners for recycled content. Choose jewelry responsibly made- your choice has power. Because my jewelry is made using hand fabrication processes, it has style and detail unacheivable via mass production.
