0.30 carat total weight is the weight only for the engagement diamond! This carat weight does not include the two diamonds in the wrap! The appraisal value is $1,170 (replacement value) and is for the engagement diamond only, so this ring is worth much more! Like new condition, prongs were just replaced this winter. I think (according to an online sizing chart) this ring & wrap is a size 7, but I may be off a bit. Beautiful ring! Msg. me for me pics of the ring & the certificate that came with the middle diamond. Great deal on this gorgeous ring!
