@xavier_exelle: Two stones I'm personally buying right now: Mozambique ruby and Tanzanian spinel. Mozambique ruby still carries a pricing gap versus Burmese. That gap is the opportunity. On spinel, Tanzanian production is consistent enough to build around, and high jewelry houses are already moving into it, red, pink, and that orange-pink color that rivals padparadscha. Demand is accelerating before the broader market has caught up. I go deeper on both in the latest episode of Gemstone Secrets.
