Yes, black onyx is a genuine gemstone belonging to the chalcedony family, which is a microcrystalline form of quartz. It forms naturally in volcanic and hydrothermal environments.
Clean black onyx with warm water, mild soap, and a soft cloth. Avoid ultrasonic cleaners and harsh chemicals. Store pieces separately to prevent scratching from harder gemstones.
