This gorgeous old buckle is by Marius Hammer of Bergen, Norway. Made of 930 silver with a gold vermeil wash, it is finished with vitreous glass (kiln-fired) enamel in a deep, rich shade of eggplant (aubergine) purple. The translucent enamel is applied over a radiating pattern of basse-taille bands. The inner edge of the buckle is accented with a line of opaque white enamel dots.
Measuring 2 5/8" tall by 1 1/2" wide, the curved buckle is in excellent condition. The color is more vibrant than I was able to capture in pictures. The back of the piece is signed "930S" along with the maker's mark of "M" with a hammer. Hammer frequently worked with 930 fineness silver, which has a slightly higher silver content than sterling (which is, by definition, 925 parts per 1000). This buckle dates to the turn of the last century and is in excellent condition. It could also be used as a scarf slide.
