Rough pieces of Whitby Jet. Beach collected along the Yorkshire coast, tested and guaranteed to be real Jet and not sea coal. The fossils are compressed wood from the Jurassic period. Perfect for carving or polishing for jewellery or simply for healing purposes (good for protection). I have a large collection of pieces from less than one gram to around 39g. The drop down menu will allow you to select up to 10g but your basket will allow you to change it up to 39g. I will send a chunk closest to your selected weight (always exact or over weight). If you need seperate pieces up to your weight then please email your requirement. Also email if you want details of the weight needed for your project or dimension minimums.
