Do you have a special date to celebrate? Perfect presents to commemorate a birthday, wedding anniversary or christening.The pebbles are various sizes (on average about 7cm), in either GREY or WHITE. Each pebble is engraved to order, so allow 7 days for the pebbles to be shipped.Please note this is a natural product, so pebbles will vary in size, colour, shape and texture. We think this is part of their charm as each one is unique, but please be aware that the photograph is an example only and your stone will be different. Shapes can be irregular and there are sometimes marks and fissures that occur naturally in the stone.When placing your order, please let me know the date you'd like in the "Comments to Seller" section when you go to checkout. If you'd like more than one birthstone, please contact me and I'll set up a reserve listing for you.I ship worldwide from the UK. Items are wrapped in tissue and packaged in bubble-lined jiffy envelopes with waterproof labels.
