who can wea blue saphire Anyone who has body parts to put them on. Really, I see a lot of questions about who is able to wear what. I feel like I’m missing out on a vital answer because there are no rules for gemstones unless you are in a group or cult or religious sect that forbids a certain stone. Now I know there are zodiac or ‘ologies’ of all kinds who say otherwise. But I sincerely am to unconcerned about what stones are suppose to be on someone or do to someone. I wear them all (if I can afford them) I today’s market that is not hard to do. Gemstones are so prolific they are used in basic metals to high end. So I would say where jewelry is concerned there is no wrongs but when you are searching it for astrological purpus i would say A person with capricorn and aquarius ascendants can wear blue sapphire as its gemstone of their ascendant lord. But condition is that saturn should not be placed in bad houses. Next for people for whom saturn is exalted they too can wear blue sapphire. For people in whose chart saturn forms vipreet raj yog they too can wear. Before wearing get the horoscope analyzed thoroughly as its very quick result giving stone. If it suits you then you will enjoy every moment of life but if it does not suit you it will create unnecessary fights out of no where. And such fights can be really dangerous. I tried wearing this many times and every time i had a clash with people in authority. Though each time i won but it just made me nervous. Few times i had to even call police. So finally removed it. I thought stone quality was not good so i changed it 2 times and everytime result was not as desired. It can be worn when sun is harassing us a lot. But first stone should be tested for few days by keeping under pillow and sleeping for few days. If you don't have bad dreams then wear it.
