Mozambique has always been a player in colored stones. Its regular supply of garnets initiated the trade and helped to develop the gemstone mining industry. Sporadic diamond finds and discovery of very nice aquamarine bring the country to higher end markets.
More recently tourmaline in bright green colors and the success of the neon blue Paraiba on the world market gave luster to the country mining reputation.
Last year new ruby findings installed this country in the top players.
Many of these rubies have a quite clean crystal and are of little light tone, more like spinel tones, very similar to Tanzanian material.
In our market we saw a quite big range of qualities on offer, some very nice unheated stones in the 3 cts range but also some lots of heated material of lower quality and even some lead-glass treated stones.
Mozambique ruby is found in the Northern Niassa province very close to Tanzania and Malawi. This proximity also explains the quite big quantity of \"Tanzania\" rubies available in our market.
