Rare HTF Retired Sterling & CZ Ring

Oxidized 925 oxidized sterling silver (stamped along with maker's mark [ALE]) with bezel set cubic zirconias. Size 9. I believe this to be a piece called their "Ihresgleichen Circle" signet band but am not certain. Some have no CZs and some even have 14K yellow gold. This one, however, is rare and I cannot find any other like it sold recently. Looks like octopus suckers! Preowned/used. Please see photos for additional size, condition, and weight inquiry. I'm open to reasonable offers!
