925 sterling silver ring

This ring has the Silpada mark plus 925 and the letters TH. The letters mean Thailand. I have tried to research this ring and none are for sale on the web. Either it is rare or the owners do not part with it. It is prior to 2013 when Silpada went out of business. The ring is size 8 and in excellent condition. Ring has a large square cut cubic zirconia.
