Industry analysts believe highly saturated + transparent untreated rubies from Winza, Morogoro, Tanzania, may become the choice locality for ruby connoisseurs. There are many Winza Tanzanian rubies in the market and I hope they are not sold as Burmese. As always, if in doubt, consult a reputed gem testing laboratory.
