Smooth and tactile, and beautifully coloured and striped, these are sold as a matched pair, with the two halves of the bivalves glued together. The purple or violet clam carries the Latin name Nuttallia Obscurata and was first described by Lovell Augustus Reeve, the famous British conchologist, in 1857.
Bivalve shells are so called because they are composed two, usually similar, hinged parts called valves. The earliest bivalve fossils found date to the early Cambrian period, making them more than 500 million years old.
These typically measure from 8cm to 9cm across. Colours and sizes will vary; these are natural shells and the photograph is of a typical example, not the shell you will receive. If you have any particular requests in terms of colour or size, please pop them in the notes - we’ll do our best to find the shell that comes closest to what you want!
All the shells we sell in our shop are real and they are from abundant and sustainable sources. The vast majority of these shells are a by product of the food industry, even the really tiny ones (used to make soups!).
Our suppliers are a socially responsible organisation in the Philippines, paying a fair daily wage, who do not export any current endangered species of any sort. We do not stock items taken solely for decorative purposes such as seahorses, puffer fish, etc.
All the shells are natural; they’ve just been cleaned and, in some cases, polished and occasionally carved or acid-etched. Isn’t nature amazing!
