Macy's Tahitian pearl ring with diamond accents

A treasure looking for a new home! Purchased about 12 years ago at Macy's; retail price was approximately $300.00. Sterling silver (see stamp, pictured) cathedral setting for a cultured Tahitian pearl (I believe it is 7- or 8mm) with 6 total diamond accents. I've noted small dents in the pearl itself - the nature of such a soft gemstone. Was not worn much, and has not been worn in 11 years. Comes in original ring box. Please let me know if you have any other questions!
