Mette + Finn Aero Pewter Blue Enamel Ring | Denmark Modernist Designer Statement Jewelry | Vintage Handmade Size 8 This wonderful ring is a stunning statement piece that stands out on your hand. Hand made of brushed pewter, it has a bit of a sheen to it. The abstract geometric form highlights the blue hallow bowl as the centerpiece. Hallmarked on the interior: Mette+Finn Ærø Denmark. Measurements:  Size: 8 Approx 15/16" Diam x 1 1/4" D ~17.9g Condition:  This well loved ring is in good vintage condition although the band shape has bent slightly over the years. Enamel itself has rough edges shown in photos, but I have looked at other pieces by M+FA and believe this is part of the design of the ring. Please see all photos.
