This ring has a unique look to it. It is my guess that this ring is part of a grand parure because the design on the ring appears to be a single blossom of which there would be several on the matching necklace, bracelet etc. The ring has a bright blue turquoise nugget with black matrix which could be Kingman turquoise and deep red coral nugget. The uneven serrated edging shows that the ring was hand made before the 1970s when machines were used to produce the serrated edges. The motif of the ring is a leaf, berry and flower motif. The ring measures 1 1/2 by 1 1/4 inches. The ring is a size 9 1/4 to 9 1/2. There are no marks on the ring but I have tested it using acid and it is Sterling.
Note; There is some type of blue dye on the silver which I can remove if I am so requested. Use the 'larger' picture mode to get a close up look at the ring.
