Rare Vintage Navajo Sterling Silver Stamped Pill Box w Turquoise Cabochon

Vintage Navajo hand stamped pill/trinket box with a turquoise cabochon in the center. Sterling silver (unmarked as most vintage Navajo sterling items are), maker's mark "A" inside box. Est 1930s-1950s as this is when this style was being made. Rare to find in Canada! Polished/cleaned but can still clean further to make look newer, I wanted to stop and err on the side of caution with a vintage, almost antique item! Turquoise has turned green due to oxidization over time. Measures approx 1.6 inches length, 1.1 inches wide, and 0.4 inches tall. Cat friendly, nonsmoking home.
