These earrings were created with the most wonderful 7.5x9mm blue kyanite. I love kyanite that has that gorgeous rust color in it. The earrings also feature artisan made lead-free pewter charms and 8mm faceted black spinel. Other than the pewter charms, these earrings are sterling silver with 20 gauge earwires. Each earring is 2 ⅝” long and weighs 4.28 grams.
