Inner diameter: approximately 16 cm Dumortierite in quartz Approximately 16mm - 16.5mm Matrix Aquamarine Approximately 27.5mm Please note that there may be some slight variations. ⚠ There are images where the blue appears dark. The actual color is closer to images 11, 12, and 13. The color is darker than item ① currently on sale, but the grade is lower due to fewer inclusions. The supplier called it "Blue Sagenitic," but I was concerned, so I had it appraised. Appraisal complete. Please check images 15 and 16. Colored material is used. There are small holes in the quartz, and the colored material is packed and sealed in them. The colored material is colored, and if a large amount is used, it will be identified as dyed, but in this case, it is considered natural quartz because the amount used is small (trace). Please check image 14. (This is not in the beads used in this bracelet) It is almost not present, but it is rarely seen. Other colors and inclusions are natural. Spherulitic Spherical I think it's cute and rare with pale blue dumortierite in granular form. I used a large matrix (mother rock) aquamarine for the top part. Milky and gentle light blue with orange-toned mother rock. As it is a natural stone, there are cracks, inclusions, natural dents, black spots, color unevenness, fine scratches, etc. Natural stone Natural stone bracelet Dumortierite in quartz Spherulitic Dumortierite in quartz Rare stone Power stone
