Photo engraving uses a diamond tipped bit to impact on the blank surface of the jewellery in very fine detail. Your photo is converted into a dot matrix image which is then engraved onto the pendant producing a high definition replica of your original photo. By creating a contrast between light and dark areas of a photo a three-dimensional holographic effect is achieved. When the light falls on the photo jewellery from different angles it gives your photo a magical glint. There is no printng involved in producing these pendants and they have no colour other than the reflective metal.
