How to maintain the Orpheum Crystal Vivid Natural Tourmaline Bracelet? Mine doesn't seem to light up now? Is there any better way?

Maintenance methods are very important. First of all, do not put tourmaline jewelry and other jewelry in the same jewelry box to avoid friction with each other and cause wear. Because the tourmaline gemstone has a slightly higher Mohs hardness than other gemstones, it will scratch and wear other jewelry with low hardness, such as jade. Diamond jewelry is corundum, which is harder than tourmaline and will wear out tourmaline, so it is best to store tourmaline jewelry separately. You can try degaussing it now, it should be almost done.
