When making a pagan wand is it necessary to use a crystal? I’ve looked everywhere and could not find a answer.
Unless one is a member of a specific tradition which has exacting requirements for how one’s wand should be made, a wand – like most other magical tools, is a personal thing. Yes, they are practical in nature, but in truth you can usually design it however you want to, and include whatever materials you want to (as long as it can still perform it’s intended function) .
Some choose to make a number of different wands, each corresponding to a particular purpose, and others choose to make a single wand that they use for all magical purposes – it’s your choice. In either case though, you would want to use materials that best represent your intended use (whether specific or general), and while using commonly accepted symbols/materials is often a popular choice, as long as you have a reason for including something else (either UPG, lore-based or just because it looks pretty damn spectacular), it’s entirely up to you.
Crystals tend to be used often, because of their inherent properties, not only in terms of correspondences (there is probably a crystal for almost any purpose we could possibly imagine), but also their ability to channel and/or hold magical energy. So if you like crystals… use them, if you don’t, that’s fine too, there are plenty of other items that can serve in their stead. Use whichever ones speak to you.
I know people who have intricately crafted wands, with crystals and carved sigils, and I know people who have store bought toy “fairy-godmother” type wands and people who have ones that are somewhere in between – all use them with pride. In the end is the only real question is… does the wand work for you? As long as the answer is yes, then that’s all that really matters.
