mong hsu meaning in Chinese

孟休

Only when it had been discovered that the dark core could be turned into deep red by means of heat treatment did rubies from mong hsu begin to find their way on to the jewellery market
但经过高热处理后的红宝石，其原本深黑紫色的核心会消失，只保留具有商业价值的深红色，所以才得从在珠宝市场上脱颖而出。
Originally , it was believed that these rubies would hardly prove suitable for use in jewellery , since untreated mong hsu ruby crystals actually display two colours : a purple to black core and a bright red periphery
的小城镇。原本蒙苏生产的红宝石是不够格当珠宝的，因为其未经处理的原石呈现两种颜色：紫至黑色的核心及鲜红色的边。
