Improving the quality of gemstones by treating them is common practice. … The most common treatment is the application of heat. Most rubies at the lower end of the market are heat treated to improve color, remove purple tinge, blue patches, and silk. These heat treatments typically occur around temperatures of 1800 °C (3300 °F).

I'm glad I wasn't the person who first decided to find out what would happen when you stick rubies in a 3300-degree oven.
