Topaz looks a lot like yellow sapphire, although it is not as rare or valuable. Yellow topaz is also much more intense than the lightly colored yellow sapphire. If you want the look alone, buying a topaz and diamond ring is a no-brainer. There are even enough varieties of it if you ever wanted to switch colors. Yellow Sapphire vs. Topaz
