need someone to render jewellery in 5 different colours

I am looking for someone to render my jewellery in 5 cool tones. The jewellery to be rendered are necklaces and the design should be modern. I am open to suggestions, but ideally would like each piece to be rendered in a modern style. Once complete I need a realistic 3D visual image of the jewellery holding true to the colour specifications. Please note that I need an experienced individual to ensure quality results.
