The heat used to create them comes from a machine.
What is lab created pink sapphire.
Lab created ruby is essentially red sapphire.
Lab created gemstones are the real deal.
That s why lab grown blue sapphires come in three lovely shades of blue not just one.
The sapphire is made by simulating the earth s heat and high pressure effects on corundum.
This process creates a very hard and durable gem which does not easily scratch or chip.
Lab sapphire is a type of synthetic corundum.
Sapphires can come in a range of colors some being blue yellow and pink with a gray or black variety turning up every once in a while.
A lab created sapphire has all the high quality characteristics of the natural gem and is more flawless with hardly any imperfections.
They re not gem imitations.
In the earlier part of the 18 th century attempts began at reproducing a corundum based gem.
The lab created pink sapphires come under the category of synthetic corundums.
However they are created in a laboratory and grown under carefully controlled conditions simulating the high pressure and heat of the earth to replicate a natural sapphire.
Durability is important because gemstones are susceptible to chipping.
Lab created sapphire corundum is a synthetically produced crystal whose with hardness on the mohs scale that is second to diamond making it extremely durable.
Since their first uses in the industrial market synthetic sapphires have been created in various gem labs as a less expensive and more easily duplicated alternative to naturally formed sapphires.
Lab created sapphires are made using corundum just as the natural gemstone is.

That s why lab created gemstones are available as alternatives.
The more expensive and hard to find natural gems in jewelry such as diamond white and fancy color sapphire blue and other colors emerald ruby and opal are favorite lab created stones.
In 1837 it was discovered that microscopic crystals of aluminum oxide the raw material for corundum could be produced synthetically and in 1877 chemist edmond fremy found a way to form gemstone quality stones using these crystals in a molten aluminum bath.
These lab created gemstones have the same chemical properties of the real stones.
Both rubies and sapphires form from varieties of corundum which is why there are no true red sapphires although shades of pink sapphires exist and are quite rare and valuable.
Crafted in a high tech controlled setting these lab created gemstones perfectly replicate the beauty of those created under the earth s surface and are an exceptional mix of master craftsmanship and science.
Lab created pink sapphires are made by a method called flame fusion they are made in such a way that they look like natural gemstones.
