These completely handmade sea glass and sea pottery coasters feature both authentic sea glass and authentic sea pottery in very colorful mosaic designs. It's fascinating to contemplate the origins of all of these pieces in households long ago, and their decades-long journeys to the New England beaches on which they were found!

Each coaster features close to 20 shards of both sea pottery and sea glass. Sea glass colors include the rare shades of amethyst, cobalt blue, cornflower blue, seafoam green, aqua, amber, lime green, teal green, and olive green, in addition to the common colors of brown and kelly green. Pottery shards include both crockery and porcelain pieces.

Since these coasters are handmade and feature sea glass and sea pottery of varying thicknesses, they are not uniformly flat as manufactured coasters are. However, as the photos demonstrate, they do support both wine glasses and tumblers adequately.

All sea glass used in these coasters is authentic, surf tumbled and beachcombed from the shores of New England.

Disclaimer and guarantee: Perfectly flawless sea glass is extremely rare. I use only my best shards of authentic, unaltered sea glass for my jewelry items, but I make no guarantee of complete flawlessness unless specifically stated as such. I do, however, guarantee complete satisfaction. If, for any reason, you are dissatisfied with your purchase within two weeks of receipt of the items, I will repair or replace your items (if possible), or issue you a full refund, whichever you choose.

If at all possible, I ship on the next day after receiving your payment, provided I am not on vacation at the time of your purchase.

Shipping is $6 to the US. Please inquire for all other destinations.
