Blue Topaz is considered a Upratna (substitute or secondary gemstone) for Blue Sapphire. While topaz is available in various colors, Blue Topaz is specifically recommended for those whose horoscopes indicate a beneficial yet weak Saturn. It can be worn on the middle finger or as a pendant. Additionally, individuals belonging to the Taurus, Gemini, Libra, Capricorn and Aquarius zodiac signs can also wear Blue Topaz.
