I believe this his is macramé, but it could be some other sort of similar craft. The stone is a gorgeous deep orange red carnelian agate and the adjustable bracelet portion is super soft and silky to the touch so it won't be uncomfortable. Carnelian agate is said to help with creativity especially in your work, and giving you the creative boost you need in the rest of your life too. It's known as an "artist's stone". Unisex. Men or women or anyone else who would be interested in wearing this.
