This is my first post on websleuths but I wanted to offer a couple of observations.. the class ring is a sapphire which coincides with a birth month of September.. so we'll assume PB's mother was born in September 1956/57.. analysis suggests PB was primarily white with at least one AA parent or grandparent.. I'm thinking mom is white & dad is black? About the jewelry... the unicorn ring looks to be part of a 'slave bracelet' concept popular in the early 90s.. you can just make out the (broken) loop part at the top of the horse where the chain linked it to the bracelet.. I was nine in 89 & her jewelry reminds me of what I might have liked to wear.. my gut tells me she's a teenager, 14 to 16 yrs old, 17 at the oldest.. & the class ring has been sized twice right? Jostens is a main manufacturer of class rings & they offer a lifetime warranty.. has anyone thought to check the ring sales for spring 1974 (usually class rings are bought in junior year) for one that matches the description of PB's. It may not tell us who she is but maybe if we know who the ring belongs to??? Just some ideas I was playing around with.
