Can anyone suggest a good place to find and buy an appropriate gemstone for a person ? My close family is undergoing lots of hardships and bad luck. Don’t know what to do. Hopefully a lucky gem or birth stone might help. Please guide on where to buy one and how to find out which one to buy. I was looking online ... sugilite seems like a nice one. Where to buy ? And how do I know there won’t be any problems if I present it to the family ? Is there anything that can go wrong ? Any precautions to keep in mind. ? Please help.
