This is a custom made Beverly K piece. Ordered it via Pearlman's when my daughter was born. She's now 12. Barely worn it in all this time.
18K white gold with diamonds and blue topaz.
Please save it to give it to your daughter on a significant occasion in her life. She will appreciate the story of how you got it when she was born, and add her own story to its history. Maybe it can be her "something blue" when she is married.
