Blue Sapphire (Neelam) is gemstone for Saturn. Saturn is the most effective planet among all planets in solar system, and it is considered most important as per astrology for its fast effect in extreme bad time of saade-saati (Saturn period). The gemstone is best for people of Capricorn zodiac sign (Makar Rashi) and Aquarius (Kumbha Rashi). Apart from that, anyone who wants to reduce the negative effects of saade-saati can wear blue Sapphire (Neelam). The sapphire’s deep blue, sparkling hue has been cherished since ancient times. Today, the gem is second in popularity only to the diamond. While you’ll find sapphires in a plethora of shades, the most popular and well-known is the navy blue sapphire. But in any hue, because of sapphires’ sturdy structure and versatile color, they’re found in gorgeous, valuable pieces around the world.
