Is it right for to wear an emerald and a ruby? My natal birth chart indicates that I have my mercury (retrograde and combust) in 6th house and sun in 5th house? Also I am told that mars is causing a lot of health and digestion-related problems for me so I should not be wearing a red coral? Please advise. I am confused which gemstone will work for my health, stability and relations in life? My date of birth is 14th september, 1963, time: 9.23 p.m., Mumbai
