It is always better to use a glamour charm that can hide in plain sight. Thus, you don't use a hand-crafted one-of-a-kind Wiccan artifact, you just enchant a mass-produced trinket. That way undercover Artemis can always claim attachment to that keepsake - maybe it's her only link to her dear-departed dad, who got it for her in Europe. Or something.
