This combination of polished onyx and copper coloured pearls is quite stunning.
I have used elongated 'twisted' onyx beads, each one measuring approximately 15 mm by 6 mm, and irregular copper-coloured pearls to separate them. The pearls are around 6 mm x 4 mm, but they do vary in size as well as shape.
The necklace is around 45.5 cms / 18 inches in length.
I have finished it with a bronze coloured toggle clasp, which makes it easy to put on and take off.
