Triangle Gold Necklace with Diamonds

This necklace was created as a birthday gift. The giftee's first initial is L, and so the design on the back was a stylisation of three overlapping L's.
 
The pendant slides along the chain and is designed to be worn showing either the front with the diamonds or the back with the overlapping L's design. These were designed at an angle so that when the model was 3D printed and cast into gold, the pattern of the 3D printed layers became a feature.
