Engraved photo pendants are made with an etching technique which relies on contrast between areas that are impacted by a diamond tipped punch and the relection off the untouched pendant surface. The diamond point is very fine and can impact 720 dots per square inch. The image is visible through the reflection of light off the engraved surface of the photo pendant. This means there is no colour or printing involved in the production of these photo pendants. 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. These pendants are classified as hypo allergenic jewellery; which means they are safe for people with nickel sensitive skin. Available in rhodium plate or 18K goldplate.
