红宝石
:以红色为主,颜色范
围从红褐色到紫色,再从橘红色至粉红色。
Rubies : Primarily red, range
from brownish and purplish shades to orangish and pinkish ones.
蓝宝石:以蓝色为主,颜色范围从深蓝色到紫蓝色,
或带绿色黄色两个色调。
Sapphires :
Primarily blue, range from dark and purplish
shades to greenish and yellowish ones.
但是,拥有纯天然颜色的红/蓝宝石,要比经过加热或是
以其他方法制造出来的宝石更有价值。
But, a natural color of ruby / sapphire will always have a
greater value than a equivalent color obtained by heating or other
processes.
