Analysis of Beauty and Rarity of Mozambique Ruby


From today’s perspective, it would be impossible to overstate the significance of African rubies in the gemstone trade.

Colors, Appearance and Size of Winza Ruby

These rubies are limited and hail from Winza, a remote village in southeastern Dodoma, Tanzania. Gems of good color (deep, rich red) and size are available.

This is an unbelievable gem. Despite the shortage and the uncertainty of supply, Winza Ruby is getting a lot of notification for several reasons, chief among them, exceptional transparency. The only Ruby with similar transparency was the Vietnamese material discovered in the 90’s and that material was more pink than red.
