General Information
All gem quality corundum that is not red is called sapphire such as
blue, orange, yellow, violet, green, white and pink. Unless a colour is
stated, sapphire is assumed to be blue. Some sapphires (colour change
sapphires) will change between blue and violet depending on the light.
There is high quality synthetic sapphire on the market.
Generally, sapphire is quite durable. Still, sapphires are subject to
chipping and fracture is handled roughly.
Reputable dealers will not use the following misleading terms.
However, for your protection, I am listing them here:
"Brazilian sapphire" is really blue topaz
or similar colour tourmaline.
"Lux sapphire", "Lynx sapphire" and "Water
Sapphire" are really Iolite.
