A useful jump oval open jump ring. A stronger, heavier jump ring in 22 gauge metal (.030 Inch). Great to use as a bail for pendants and charms, because the opening is on the long side of the oval, which tends to prevent things slipping out of the ring.
These rings are made of brass then plated with gold.
Measurements: 4mm long, 3mm wide. Thickness is 22 Gauge or 0.30 Inch.
