Buyer intelligence
Color is the main first-pass factor, but commercial varieties behave very differently. Paraíba-type/cuprian, rubellite, indicolite, chrome and multicolor stones require variety-specific comparisons.
Care
Generally wearable; protect from hard impact and thermal shock. Treatment status can affect care.
BARADAK uses summarized gemological information and links to technical sources; commercial ranges do not replace a laboratory report or formal appraisal.
