All of HighChi Energy Jewelry is made of recycled 925 sterling silver, or sterling silver with 18k gold plating, or solid 14 or 18k gold.
If your jewelry tarnishes quickly or becomes very dark, it usually is because you are around a lot of negative electromagnetic energy fields, or other negative energies. In the case of sterling silver we suggest using a good silver polish and a soft cloth to clean it, and if it’s really tarnished it can take a lot of work and elbow grease.
There is also an ionic jewelry cleaner for around $30 on Amazon that works well for silver and gold, but in the case of tarnished sterling silver, there is nothing like elbow grease. You can also take it to your jeweler and they will clean it for you.
