A wedge shaped area on the left side of the ring was inlaid with lapis to look like a lake. The sky area was inlaid with sleeping beauty type turquoise. The sun is a yellow sapphire. The sapphire is not set with a gold tube, instead it was inserted from the back and is held in place with a bezel of turquoise, so  to speak, at the top. A piece of gold tubing was inserted into the back of the turquoise to hold the yellow sapphire in place and to allow it to be cleaned from the back.
