Antonio Pineda crafted this incredible treasure. The ring is made from 3 rectangular shaped tourmaline, very clear and fine stones. The gold is marked 14kt and also with the Antonio crown. Picture 3 shows a blurry ring but the hallmark is clear on the back inside band that is in focus. The ring is heavy at 14 grams. The large face front measurement of the piece is .75in. x .75in. The ring presently fits approximately a size 5 and is capable of being sized by an accomplished jeweler. The ring has no cracks but does have some tarnish (which shows thru one of the very clear stones) and light scratches that are magnified in the photography. The condition is exceptional and could use a good cleaning from a jeweler. The pix from the back of the ring shows the barrel cuts to the stones. The most interesting thing about this ring is how the three stones are set. They are all different angles to one another and they collect light from one another which is quite mesmerizing. When on the finger it looks stunning and important which it is. Antonio Pineda solid gold pieces are rarely found and this green tourmaline is rare and an exceptional find.
