Kaunis Koru Finland Vintage Modernist Sterling Silver & Green Stones Unique Ring. I've never seen the similar design before, it seems it was made in 1970s. Kaunis Koru was active in Helsinki from 1954 to 1989, then merge with Kalevala Koru. Kaunis Koru made jewellery of pure form, often geometric and timeless.
Famous Finnish designers Paula Häivaoja, Björn Weckström, Pekka Piekainen and Mirjam Salminen started their careers there. Top part of the ring is 1.9 cm x 1.9 cm, height is around 1.2 cm. Band's width on sides and bottom is about 6 mm, thickness is about 1.1 mm. Weight is about 12 gr on my kitchen scale!
Inside diameter is 17 mm, because of the ring's thickness and width it will fit comfortably to UK sizes M - M 1/2. The stones look like raw polished Emeralds with a lot of natural inclusions, but I'm not sure these are Emeralds, it maybe any other stones similar in colour or even glass filled stones.The stones' colour on my pictures is pretty much correct. The ring is in very good vintage condition with some signs of use. Central (third) stone is cracked, but because of the ring design and stone structure it's unnoticeable when wearing. The ring will be send by signed-for, tracked and insured service. So the photos are the most important part of description.
