The camera is a 46 megapixel _SD1 Merrill_ with the 150mm f/2.8 OS macro lens both from _Sigma._ The long focal length allows enough working distance from the lens to the 2" in diameter brooch for lights. The over head light is not a soft box as shown here. It's a diffusion panel with a _Dynalite_ head on a boom above it. By moving the head either higher above the panel for softer light or lower for a harsher quality exactly the right light is created to illuminate the colorful sapphires. The _Chimera_ 48" square diffusion panel to the brooch's right is the large source required to evenly illuminate the spiral windings. Finally a rose colored gel is placed over a _Dynalite_ studio head with a 30º grid. This creates the graduated glow that matches the center sapphire's color.
