Uncolored Ultimate Grade Kyanite With Appraisal Report The appraisal report uses the pronunciation "kyanite" according to English phonetic notation. The beads are assembled with various sizes, approximately 20mm to 21mm in size. Inner circumference approximately 19 cm ★★Important Information Regarding Kyanite★★ I have observed the changes in the distribution of kyanite for many years. The following is my personal opinion. ① In the early days, wonderful, uncolored, deep blue kyanite was distributed. ② Later, items with brown inclusions, some with quartz, transparent ones, and colored kyanite became available. ③ Under the name "blue-green kyanite," items that were not deep blue, but rather discolored or mixed with fuchsite or quartz, began to circulate. ④ Under the name "transparent kyanite," kyanite-in-quartz, which is actually quartz with kyanite inclusions, became widely available. It's a situation that is difficult for buyers to understand, but having observed these changes, I believe that the early, deep blue, uncolored kyanite is the rarest and most valuable. Some sellers may have different opinions, but it's clear when looking at larimar and charoite. Recently, larimar beads with brown inclusions are sold as "chocolate larimar," and charoite that is not a beautiful purple color due to discoloration is sold as "pink charoite." Mineral resources are finite, so they undergo such changes. This is uncolored kyanite of a grade that is no longer available. It is deep blue and a superb piece with a beautiful sheen. Kyanite has the property of varying hardness depending on the crystal direction, with a Mohs hardness of 7.5 in the longitudinal direction of the columnar crystal and a Mohs hardness of 4 in the transverse direction. Because of this, it is also known as "two-hardness stone." This property makes kyanite a difficult stone to process. For the protection of the beads, uncolored kyanite bracelets are treated with a transparent impregnation process. We look forward to you welcoming this beautiful piece with a wonderful connection.
