In my opinion, the both of them are equally powerful. There is no such thing where a holy object is more holy than another (If the both of them comes from the same enlightened being). It is up to our Karma whether if we are able to be protected by these holy objects. If you still can't make up your mind hahahahha. I recommend you to pick the crystal because it is more attracting to the eye. When you wear it, you will attract more people to look at it and when they look at it, they will also collect merits. This is just my personal opinion, you can choose whatever you like. I guess you have already bought it since you have already posted this for about 3 years ago.
