A useful jump oval open jump ring. A stronger, heavier jump ring in 21 gauge metal (.028 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 silver.
Measurements: 4mm long, 3mm wide. Thickness is 21 Gauge or 0.028 Inch.
