An 8-carat Alexandrite stone weighs around 1.6 gms (1.44 gms) and is known for its color-changing properties. Ranging from beautiful shades of green to deep and fiery red, this gem has a lot to offer to people who have weak Mars in their birth chart. Alexandrite has a similar beauty to emerald during the day, and it transforms into an extravagant ruby in incandescent lighting because of the chatoyancy effect similar to that seen in the Cats eye. The 8 carat alexandrite price ranges from INR 5 lakh to 50 lakh ($6,035.72-$60,355.20) and above based on color transitions, clarity, cut, and origin. As per Vedic astrology, an alexandrite 8 carat ring benefits Virgo, Taurus, Gemini, and Leo zodiacs.
