She's finally here!
She sure needed a bath when she arrived, literally layers of grime, but when after I cleaned her OMG she was amazing!!!
As it turns out, it's definitely a late OEC diamond in the center just over 7mm (probably a little over 1.25 ct), the two side stones are 4mm round brilliants (about .25 ct), the two diamonds at the top and bottom of the center diamond are about 3mm (about .10 ct) round brilliants, and there are 6 teeny tiny single cuts among the filigree, about 1.5 mm each.
It's a quite delicate ring with the filigree and engraving, but the prongs are well worn and defnitely need to be refurbed. I'm going to hold on to it a while before I send it out so I can enjoy her.
Without further ado...pics!!!
