Technique: Fabrication Method
rod/stock Note: Looks like high carat gold. Hammered from rectangular stock with squared blunt ends. Ends seem cut, slightly beveled. One retains vestige of bend-to-break on inside surface (with any sharp edges smoothed) [more fully polished]; divet pock marks on other end (not fully polished). Slight seams along thin sides. Inside of ring, unidirectional diagonal (lower right to upper left) sanding marks. Longer striations parallel to sides (2 or 3 deeper gouges) on inner surface. Inside of ring has alot of areas of casting flaws. Possibly shear fracture flaw and area of surface loss (delaminated) on outer surface.
Treatment: Conservation Performed
Surface cleaned/degreased with acetone on cotton swab
