The image below is a example of an afternoons collecting from my local beach, yesterday Sunday 25 July. I normally have a helper but he was playing cricket!
You can see that these pieces of Sea Glass are all smaller than a 5 pence piece. This is the perfect size for working into earrings and setting into rings. Some bits are way too small to work with but yesterday, any size was a bonus. The beach was a bit lacking on the sea glass front and I needed another set of eyes.

These examples are all jewellery quality glass which means they are all naturally tumbled in the sea to produce a perfectly smooth item ready to be crafted into a wearable piece of jewellery.

I do not tumble any of the glass I collect, nor do I want to, this is why I am very choosy with the pieces I pick up from the beach. I welcome any donations of sea glass from friends and family, but I am starting to get more and more fussy with the bits I except, due to the space required to keep it all. I can only really work with smooth edged glass, and frosted is preferable (no shiny or sharp bits please) and nothing too small! Note the rare blue bits in the picture.
