TOPAZ November Birthstone. In shades of yellow, brown, honey, green, blue, red, pink and sometimes no color at all, Topaz has a mass appeal. Topaz is often found in an amber gold, yellow, or a blushing pink orange but a pale pink or a sherry red Topaz is very exceptional. The most prized color of Topaz is called Imperial Topaz and features a magnificent orange with pink undertones. Blue, once the most rare color of Topaz, is the most common today due to manâs ability to enhance its color; Topaz with a naturally blue color is very rare. The ancient Egyptians and Romans associated this golden gem with the sun god giving it the power to protect and heal.
