A substantial 4.18 carat copper and manganese bearing tourmaline from Mozambique, certified by GIA with a full origin report.

Internal fracturing and inclusions are visible throughout the body as shown in the photos; buyers should review all images carefully. The GIA treatment field directs to a QR code for details — no explicit clarity enhancement is noted on the face of this report, however internal characteristics are visible to the naked eye.
