I made a wonderful wand that I gave to a friend of my ex. It had a double-tip of a quartz obelisk and an obsidian obelisk, with an amber pommel. We found it to be a powerful tool.
I think that for those who find the use of wands to be good tools, and for those attune to the powers of crystals and natural resources, they can be serious additions to a ritual.
Quartz tips or pommels can help direct and clear your energies and intent as you direct them through the wand.
