Synthetic rubies (also known as created, cultured, or lab-grown rubies) are created through an artificial process that usually involves high temperature and pressure. From a chemical standpoint, lab-created rubies are no different from natural ones and are considered real rubies.
How can you tell if a ruby is lab created?
Structural patterns in lab-grown rubies are characteristically curved indicating their artificial origin. Created rubies may also have gas bubbles inside, which form during the manufacturing process. The process of growing synthetic gems leaves certain traces in the stone that can help to identify lab-created rubies.
How much are man made rubies worth?
Laboratory grown synthetic ruby
The average weight is 1.96ct., priced at $30/ct. Gems this size would be perfect for a ring, earrings, or would make a delicate necklace. Price shown is per gemstone.
Are lab created rubies valuable?
Almost all rubies that are created in a lab are strengthened with dye. … They are identical in their chemical composition, but lab-created rubies are less expensive than natural ones and unlike natural rubies, they are not flawed.
Can you make rubies at home?
Creating synthetic gemstones requires very high heat. One of the most inexpensive processes for synthesizing rubies is the flame fusion method. First developed by August Verneuil, this method begins with a powder mixture that is heated until it has melted. This material is then made to solidify as a crystal.

Why are Burmese rubies so expensive?
One of the main reasons that Burmese rubies are so valuable is because of their very specific, extremely saturated colour, caused by a high chromium content in the ground from which they are extracted.
Does lab created mean fake?
Stones created in a lab are chemically, physically and optically identical to those mined underground — but they have fewer flaws, a lighter carbon footprint and cost less, too. … They’re not gem imitations; lab-created gemstones are the real deal.
How are lab created rubies made?
Elements. Lab created rubies are made by combining a specific recipe of minerals, in order to produce a fiery red variety of lab grown crystals. … The color is the result of combining aluminum oxide (which, by itself, is colorless) with chrome, creating a mineral known a corundum, or ruby.
How can you tell if a gemstone is synthetic?
Synthetic gemstones are more likely to be rich and vivid in color, and are virtually inclusion or blemish-free when you look at them. Almost always, natural gemstones will have some type of inclusion or color differentiation.
Do rubies crack easily?
Rubies are extremely hard and rank almost at the top of the toughness scale. They’re intensely resistant to scratches and cleavage and are near-impossible to break. Even if the ruby is cracked, it can still withstand further damage. Although, a bad enough crack can eventually break the stone.
What is Ruby made of?
Ruby, gemstone composed of transparent red corundum (q.v.), a mineral form of aluminum oxide, Al2O3. Its colour varies from deep cochineal to pale rose red, in some cases with a tinge of purple; the most valued is a pigeon-blood red.
How do you make fake rubies?
Synthetic ruby is often made by simply melting aluminum oxide that contains a trace of chromium. The resulting crystal has the same internal atomic structure as natural ruby as well as the same optical properties, hardness, and chemical composition.
