Chunky 4mm bangle with charms Sterling silver 4mm round bangle with sterling silver ring charms. £85.00 A random assortment of sterling and fine silver charms on a heavy 4mm round bangle. I love the weight of this bangle, and the jingley-ness (I'm sure that's a word). Standard internal diameter is 65mm but just get in touch if you'd like a different size. Hallmarked at the Goldsmiths Hall - London Assay Office including my makers mark. This comes in Becky Pearce Designs gift box.
