Thes earrings weigh about 4g each and are about 20mm in diameter. They are not hallmarked. They are formed by inserting different sizes of tubing within eachother and soldered in place. A section about 10mm wide is then split to give the earrings you see – that’s why they look like a mirror image! Not in my shop but available for £50 +p&p. Please contact me if you are interested. They will come with hook wire fittings as you can see elsewhere in my shop, but they could be changed.
