Amber & Sterling Silver Ornate size 6 Ring

Designer / Fine Jewelry / Vintage Lori Bonn Amber & Sterling Silver Ornate Approximately size 6 Ring stamped TM 426 325 I thought this ring was Lori Bonn, I remember buying at Nordstrom, Lori Bonn trunk show, but there is no stamp. The quality is as nice like LB so maybe when she first started designing all her pieces may not have been stamped. Approximately 20 years old.
