Uncolored Ultimate Grade Kyanite With Appraisal Report The appraisal report uses "Kyanite" according to English pronunciation. The beads are assembled with various sizes, approximately 18.1mm to 18.9mm in size. Inner circumference approximately 17cm ★★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 transparency due to quartz, and colored kyanite appeared. 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, flooded the market. It's a situation that's 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 being sold as "chocolate larimar," and charoite that isn't a beautiful purple color due to discoloration is being sold as "pink charoite." Mineral resources are finite, so they undergo these kinds of 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. To protect the beads, uncolored kyanite bracelets are treated with a transparent impregnation process. We look forward to you welcoming this with a wonderful connection.
