About Sapphires

Although blue sapphire is the most popular with designers and the public. Sapphire actually comes in all colors except red. The red ones are called Rubies, many places have sapphire deposits with the most popular ones being Myanmar, Ceylon, Sri Lanka, Madagascar and now Nigeria. Sapphires and rubies are both made of corundum and the color differences come from traces of iron titanium and chromium. A moh’s hardness of 9 makes them some of the most durable gems with only diamonds being harder with the exception of man made moissanite  coming in between with a hardness of 9.5 on the moh’s scale of harness.

Pastel Sapphires

Pastel sapphires are stones with pale colors, in the past they were seldom seen in jewelry as they were thought to be unsuitable due to there pale coloring. But they too now find there way into the industry and make wonderful and beautiful pieces and even entire collections of design concepts. I have used diamond cut pastel sapphires in my designs for many years with my clients responding very positively to the look.

What is corundum made from?

Corundum is comprised of only aluminum and oxygen which when combined make Aluminum Oxide, but it must have a silicone free environment. Natural corundum in its pure state would be colorless, so the colors we find in it are cause by traces of other minerals like iron, titanium, and chromium. Actually colorless or white sapphire is very rare. However it has been used as a diamond substitute in the past and it is making a comeback in recent times as an accent to colored stones.
