Tideline Treasure is a business built from a lifetime spent on Cornish beaches collecting sea glass.

My name is Penny and my jewellery is handmade on my workbench at home from sea glass, sea pottery and sterling silver.

My ethos is to make unique pieces of jewellery while using as many recycled and recyclable materials as possible. This includes packaging, recycled sterling silver and hand picked sea glass and sea pottery, helping to reduce the amount of man-made rubbish found on our beaches and in our oceans - proof that recycling can be beautiful.


Most of my finds are from beaches around my home town of Looe in Cornwall but I beachcomb wherever I get the chance. I also have sea glass from the Scottish Highlands, where my daughter lived for several years.


I have a Looe Island Collection made from sea glass found on the Island. I donate 20% of all sales from this collection to the Cornwall Wildlife Trust who own and manage the Island


I hope you enjoy browsing my website and please come say hello next time you're on Instagram or Facebook.
