You are Ashtam Mangalik from Moon chart but Mars is debilitated therefore the mangal dosha gets cancelled. But your marital life and marriage will be in turmoil because of other factors. You have 12th lord Saturn and 6th lord Sun in the 7th house. Saturn and Sun are inimical and certainly their conjunction in the 7th house weaken the 7th house. Saturn is the 12th lord which is a malefic house and you should not be strengthening it by wearing the stone. Emerald is fine.
