I know that the 2 smaller stones are what is called checkerboard cut, though i do not know what the name of the cut of the main stone is. Also a decently sized stone. I can only tell you that the main stone is 1 7/10" tall by 1/2" across.
The flanking stones echo the slight ovoid shape of the main stone and are 1/4 tall. Band size is 7 american.
The ring is originally mid-century. The band is 1/5" tall at tallest (right adjacent to the stone setting) it is 1/10" thick with the gold that was added about 10 years ago. The ring was originally custom made in the mid-century in galicia spain to hold some stones that were special to the original owner. Marker's and/or other marks.I took the ring to a jeweler to weigh it. It comes in (stones and all) at 8.68 grams. Very good vintage condition band and stone settings are very sound. The images are the majority of the listing description, so take a look at them closely. I just don't have the stamina to create new listings for those.
I haven't initially individually listed items because i don't have enough listing slots to so. Trying to downsize some, though extremely melancholically. I appreciate you taking the time to view my listing.
