About 8 years ago I took two classes with Lola Brooks at the Craft Student's League (now closed, sadly) in NYC. She is one of the few who is incredibly creative and talented yet is personable and intelligent enough to be able to teach others. Her students adore her and she is one of my heroes. She's also a rock star in the art jewelry world.
This piece is called Rose Cut Neckpiece and it's made from stainless steel, 18k gold, and rose-cut smoky quartz gemstones. You can buy it here: http://tinyurl.com/3922lo
