Gemstone recommendation

[finding_a_way]

Dear learned members,

Could you please recommend for me a life stone based on my birth details (for general good luck and prosperity):

Date: 25/04/1984
Time: 23:05
Place: London

Please tell me if it should be of a certain weight and in which hand/finger should it be worn

Thank you.

Any help is greatly appreciated.
