Yes, there are.
To many people, Sapphires are blue. However, Sapphires (Corundum) come in a whole myriad of colors! You can find them in pink, orange, purple/violet, green, black, parti-colors etc. There are even color-change varieties! (Red corundum is called Ruby)
In its purest form, Sapphire (Aluminium Oxide) is colorless and is called "White" Sapphire. Colored varieties are the result of impurities. For e.g. Blues are colored by iron & tianium, Pinks by chromium, Yellows & Greens by iron and so on.
Although a gemstone in its own right, white Sapphires are often seen as an economical alternative to Diamonds. They have a hardness of 9 on the Moh's scale and are therefore very durable. The refractive index is 1.76-1.77, which is lower than Diamond (2.41) but higher than Quartz (1.54). (This means it has a lower brilliance potential than Diamond, but makes an attractive stone compared to Quartz.)
Me - I love gemstones and I'm a gemologist.
