The Ocean Scarf

A rare agate that looks like an impressionist painting of rolling ocean waves, but also with more than a suspicion of a breaching whale - see its eye on the right.

That makes it stunningly original, and a real talking point, and it works really well in both the square and oblong shapes

Agate is a colourful variety of quartz, and other quartz varieties include amethyst, opal, onyx, jasper, and Tiger’s Eye.

It was named after the river Achates by Theophrastus, a Greek philosopher and naturalist, but was actually created in volcanic rocks at literally melting temperatures.
