Dear mohan,
To get more effect of gemstones :
Ist thing is that you should choose apropriate gemstone according to your birth chart and planetary position.
Then check the quality and clarity of the stone u are going to wear.
Make sure for astrological purpose you should always wear 100% natural stone without any heated and treated stone.
and do energisation and cleansing of the stone before wearing.
Wear it in apropriate metal and proper fingure by asking any experience knowledgable asrtrologer.
these are certain things you can follow to get more benefit from the stone u r going to wear.
Thank you
