緬甸曼德勒東北方向90英里的地方，有一個叫做抹谷的地區，無疑是世界最重要的紅寶石產區。
抹谷區長約20英里，海拔4000英尺，出產高品質紅寶石，緬甸因此而舉世聞名。
最上等品質的緬甸紅寶石呈現及濃郁飽和的紅色。
大部分紅寶石出產於河床衝擊层中的結晶灰岩與大理石。
抹谷地區何時開始開採礦石，已經無從可考，但周圍地區已經出土了史前工具。
早期紀錄顯示，緬甸國王於1597年下令保護抹谷礦區，使其免遭當地撣族統治。
開採礦物十分艱苦，直至1780年時，人們不得不使用奴隸來補充當地人手。
一旦開採出貴重罕有的大型寶石，將被自動上交給國王，開採工人則得不到任何獎勵。
新上任的地方官員更對開採出的寶石徵收重稅，令工人的生存狀況愈發艱難。
統治者懷疑開採工人將大型紅寶石擊碎，可能是歷史上大型紅寶石極其稀有的原因之一。
當然，也有可能是現實中，大型寶石的存在機率本就微乎其微。
直至1886年，在政治與經濟的雙重因素影響之下，英國將上緬甸併入英屬印度。
此後幾年間，英國政府將開礦權交給龐德街珠寶商Edwin Streeter，其成立了Burma Ruby Mines Ltd.。英國人將較為先進的開礦方法帶入緬甸，結果卻不盡如人意。
1931年時，開礦結束，抹谷地區被交還於當地工人，他們仍然使用幾百年前流傳下來的古老開礦方法工作。
