Examine the color of the stone. Topaz varieties occur most commonly in golden brown to yellow tones but also in orange, red, blue, green and pink. The most popular sapphire variety is the blue sapphire, but it can occur in almost any color (except red, which is classified as a ruby.)
Test the hardness of the stone. There are testing kits that examine the hardness of the stone on the Mohs scale, which is used by gemologists. The scale ranges from 1 (talc) to 10 (diamond). A topaz ranks at an 8 on the Mohs, while sapphire is a 9. The kit will usually come with different specimens or minerals that are used to scratch the gemstone, which will allow you to identify where the gemstone lies on the hardness scale.

Although some gemstones are more identifiable than others, topaz and sapphire share many physical characteristics that make them difficult for the untrained eye to tell apart. Their similarities in color varieties, hardness and luster are comparable, but there are also individual qualities of each stone that distinguish them from one another. With a few observations and tests, it's possible to tell the difference between the two.
