The "Martina Collection" is so unique from a design stance. The glass is actually shaped as a bulb and the bottom glass holder is designed like the bottom of a vintage screw type bulb.The wiring has a "vintage" element since it is twisted the way Thomas Edison first introduced the bulb. The metal work is black while the glass holder is brass. This is the island model shown but there are many matching units available such as a circular chandelier, flush mount, wall sconce and more.
