Viewing the warm colour red is said to increase the pulse and respiration. The colour is associated with love, desire and passion. It is said to represent masculinity if worn by a male, as well as demonstrating command, nobility and lordship. When worn by a female it has an alluring and seductive nature, and historically was said to show pride and obstinacy. Associated with the planet Mars and Tuesdays, in antiquity the colour was used to cover those who had bravely died in battle. It was often worn in battle to strike fear directly into the hearts of the opposing army.
For those wanting a red gemstone, there is surprisingly little choice. The best known and historically most sought after is the Ruby. Although it is often the most expensive of red gemstones, Rubies are normally heavily included. If you are after a very transparent red gemstone then there are currently some beautifully clear Spinels on the market.
