Spinel has a "long, storied history." Some of the most famous "rubies" in the world belonging to monarchs, including the Black Prince's Ruby, a centerpiece of the British Imperial State Crown, turned out to be spinel once modern science caught up with it. Why it was impersonating a ruby nobody knows! Perhaps it's because spinel and ruby often grow in the same mine.
You may notice the Black Prince's Ruby has a tiny stone in it. Why? Some Einstein’s bright idea was to cut a hole in this lovely stone to place a feather in it! He should’ve known that fads come and go!!
Spinels (MAI2O4) are minerals, namely octahedral crystals, consisting mostly of magnesium and aluminum. They tend to be more reflective -- glittering more than rubies, its former neighbor. Like sapphires, spinels come in a range of vibrant colors, perhaps the most coveted hues being red and blue. Yet, all the colors are gorgeous!

Fortunately for Savvy Shoppers, the popularity and demand for spinel gemstones hasn't caught up with its beauty, so you can get a big rock for much less than you'd pay for sapphires or rubies.
