Jewelry Design The Ray Brooch by Wonhee Kim The inspiration for the Ray Brooch comes from the ray of sunlight appearing through the clouds on a cloudy day. The luster of the pearls gives an extra soft glow, and the sparkle of the diamonds stands out like a ray of sunlight next to dark metal and black diamonds. The base color of the brooch is dark since it uses black rhodium-plated metal and a black diamond, but mixing with bright gemstones brightens up the entire piece.
