This is a 14mm onyx stone engraved with the Japanese character for "love" (愛). Onyx itself has been popular with people since ancient times, so it is widely available and not particularly rare. However, it is the various engravings on it that make it special. While common engravings include things like dragons and Sanskrit characters, which are considered to have protective properties, those with Japanese characters are considered very valuable due to the difficulty of the process. This one is engraved with the character "love" along with a family crest of a moon, and it shines beautifully. Onyx is known as a powerful stone for warding off evil and bad luck, and it can be expected to have effects such as mental stability, strengthening of will, and support for achieving goals. It protects the wearer from external malice and negative energy, calms inner evil thoughts, cultivates calm judgment and strong will, and is also called the "stone of severing ties" as it cuts off bad relationships and attracts good ones.
