From today’s perspective, it would be impossible to overstate the significance of African rubies in the gemstone trade. East African ruby, specifically from Mozambique, Tanzania and Madagascar has recently dominated the market for several reasons that include lack of thermal enhancement, brilliancy, size and color. No other geographical region has successfully competed with Mozambique ruby with regard to quality and size. Rubies have been found in Mozambique since the Portuguese colonial era from 1498-1975, although producing nothing comparable to today’s quality ruby findings.



Ranges of Presence

It should be noted that Mozambique ruby fought a tough battle for acceptance in well-established markets against more traditionally desirable provenances like Burma (Myanmar). It was initially thought that there would result a market-flood of unheated ruby which would compromise the rarity of the rubies. It was soon apparent that this would not be the case. Time revealed that the attributes most wanted in the industry would be a power of beauty, appearance and size, rather than just its provenance.

Characteristics of Mozambique Quality


With the existence of the right chemical composition and fluorescence in a good portion of Mozambique ruby, the stunning vivid-red appearance combined with high-clarity produced the equivalent of the finest Burmese colors. Today, the most sought after Mozambique rubies are of unheated GRS type Pigeon’s Blood color, of large size and fine clarity, and are unparalleled in the world of rubies. GRS confidently predicted that Mozambique ruby will continue to rise andfame as a landmark ruby occurrence within gemstone history

  1. 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.

    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.
