This is a bracelet made of vibrantly colored Larimar (Blue Pectolite) tumbled stones. Unlike the common thin tumbled stones, these have thickness, allowing you to enjoy the color and the turtle shell patterns. As they are tumbled stones, there is some variation in size, but most are around 5-6mm. There are also some deep blue Larimar pieces, which are highly recommended. It has been stored in a case, unused. I am selling it to someone who appreciates natural stones, as I am organizing my collection. Please feel free to comment if you have any questions. Thank you.
