Faire face Concrete - Rectangular prism pendant necklace

I’m living in a concrete jungle - buildings are in concrete, roads and bridges are in concrete, so, does that mean concrete can only be used for infrastructure? This is a silver necklace with a rectangular prism concrete pendant. We are not using any pigment during the process nor put on coating to finish off. We would like to keep the authentic look of the concrete as well as achieving minimalism. Measurement of the concrete pendant: - 4.5cm x 0.9cm x 0.9cm Length of the chain: - 21 [A little note that you may wanna know] *** This item is a fair faced concrete item. *** Fair faced concrete is a concrete surface that on completion of the forming process, requires no further treatment other than curing. No painting nor patching to cover up any defects. So the technique and perfect control is the key to achieve a piece of quality fair faced concrete. One need to touch and feel it in person in order to enjoy this highest level of craftsmanship. *** no worries if water just splash on it, the beads turn a bit dark, after a while when the beads are dried, you can see the original color. However this means if its tea or coffee go on it then stains lasts. *** Tiny little bubble is expected. For those who have concern on the bubble, then we are afraid concrete may not be your choice *** For those trays solely in grey, since those are handmade and due to the characteristic of concrete, there is possibility that the grey tone may not be even.
