The hue of the gemstones is a key factor in determining the efficacy of Vedic astrology. This is due to the fact that color therapy is a science that is said to benefit from jewels. Colors have a psychological impact and have good benefits on the body and mind. When determining which is suitable stone for Kumbha Rashi, Neelam Ratna is the most exceptional choice. It's been believed that a gemstone's hue has an impact on the human body as well. For example, the captivating blue color of blue sapphire is suggestive of the deep blue sky or the ocean. Calm and serenity are symbolized by the color blue.
