This design is a lovely gift to celebrate twins! I create unique designs by hand and carve them into pebbles and stone. Each pebble is carefully selected, then the design is cut by hand, then carved into the pebble. They all vary in size, shape, colour, etc, and measure approx 2.5 4.5 across. There are 2 different finishes, either so the design is carved into the stone or raised out of it. Please advise when ordering which design is preferred, otherwise I will chose one on your behalf. Heres some of my feedback: absolutely fantastic I cant say anymore than that Beautiful stone, exactly as ordered. You are very skilled. Thank you Beautifully crafted keepsake, thank you! Very happy with item fast delivery thank you so much Really happy! Great product, highly recommended seller. Love it a unique valentine gift I make a variety of different designs, from gifts for weddings, to pebbles to treasure for new arrivals, please see my other items. You can view examples of my other items on Facebook findydesigns. I make all my designs by hand and made to order, there is no computer involved. All pebbles and stones are untouched aside from the design. Every pebble and stone is different in colour size, texture and structure. This does mean that when carving the design small imperfections will show but this is all part of the natural look of the pebble. It means the pebble doesnt look manufactured or mass produced and adds to the unique element of the gift. Orders take approximately 5 working days to arrive. If it is an urgent order then please let me know and I will do my best to accommodate. Returns are not possible as this is a personalised item, unless there is a defect with the product itself.
