This oval is eye clean and with fine crystal which is unusual for cuprian tourmaline from Mozambique. Its lavender color is lightly toned, but still a nice pastel that is well saturated. It weighs 5.13 carats.
The rough for the lightly toned lavender was cut from a large dark purplish red nodule that had been heated to lighten it. It would have probably gone completely light blue if the heating continued. The blue is from a low level of copper. Lavender, that is as well saturated as this stone has, is very rare in tourmaline and may even require copper as a chromophore with the reddish shades from manganese. This bright and eye clean oval weighs 5.13 carats. I purchased the rough for this oval before copper was discovered in gem quality tourmaline from Mozambique.
