A client came to me for a replacement wedding band made of koa (a native Hawaiian hardwood) for his wife. To ensure that the ring would be strong enough to stand up to daily wear, I first made a white gold ring with an inverted T-shaped cross section that serves as both a strong skeleton and decorative stripe down the center of the band. I cut matching sections of wood from reclaimed koa floorboards and cemented them into the corners of the gold frame, and then filed into shape. The two halves were mitered from the same piece of koa so although it's difficult to see at this size, the grain of the wood is continuous along both sides of the ring.
