Paragon Lake is a jewelry manufacturer that partners with independent jewelers and designers to deliver custom rings, earrings, and pendants to consumers.  They work only with gold, platinum and palladium, and while you can re-use a center stone from an existing piece, they do not allow recycled metal.  Right now the process includes going to a Paragon Lake retail partner, sketching the perfect item with the help of  jeweler and then returning some time later to review and approve the piece.  Aiming to make the process even easier, Paragon Lake is working on online software that will present jewelers with 3D modeling capabilities eliminating sketching and allowing real-time preview.  In July, the company raised $5.8 million in series A funding from Highland Capital Partners and Canaan Partners.
