This large size sterling silver ring and earring set was made by Minas (Minas Spiridis), Greek jeweler since the 1970's. His work is characterized by fluid, streamlined designs. Minas died in April, 2020 at the age of 82.
The diagonal stripe design is sterling and what I believe to be a gold wash. The ring is 1 3/16 inches in length and 13/16" in width. It is size 6 1/2 and can easily be sized up or down. Condition is excellent. Price is $435.
The earrings are 1 1/4" long and 7/8" wide. Clip backs can be converted to posts. One of the earrings has two minor dents on the front and top. Price is $350.
Ring and earrings can be purchased separately or for $735. for the set.
