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. If you do not have an option to send your ruby to a laboratory for testing, you may try to identify its origin by following these tips.
Since synthetic rubies are created in labs in a controlled process, they have higher clarity than most natural rubies. This does not mean that all flawless rubies are necessarily artificial, but if a stone of a high clarity grade is natural, it will be very expensive and hard to find.
So if a high-clarity ruby is significantly cheaper than an identical natural stone, then most likely, you are dealing with a lab-created ruby. Another sign that ruby is lab-grown is its size. Large natural rubies are rare and very pricy as a result. For example, a 2-carat ruby is harder to find in nature than to create synthetically. So if a ruby is quite large and still affordable, it is likely to be artificial. Considering the above, the low price is proof that the stone might be synthetic.
If a ruby has an intense red colour, high clarity, large size and relatively low cost, it is most likely not natural.

Although synthetic and natural rubies are virtually identical, there are some very subtle differences that can be detected with the appropriate equipment. Structural cues: Gemologists can tell whether a ruby is synthetic by looking at its structure under a microscope.
Lab-created rubies may also have microscopic gas bubbles inside, which were formed during the manufacturing process. More: Click here to see natural ruby jewelry. Chemical differences: The process for creating a synthetic ruby leaves certain chemical traces in the stone, which are not present in natural gems.
For example, tiny amounts of lead can indicate that a ruby was artificially created. Gemstone creation processes are continuously improved, and lab-created stones are becoming almost perfectly identical to their natural analogues. Perfect clarity: Lab-grown rubies are created in a controlled process that minimizes internal flaws. As a result, synthetic stones have higher clarity than most natural ones. This is not to say that a flawless ruby is necessarily artificial, but if such a stone is natural, it will be very expensive.
If a high-clarity ruby is substantially cheaper than a comparable natural ruby, then it is likely that you are dealing with a synthetic stone. See what natural rubies look like here and here. They're not gem imitations; lab-created gemstones are the real deal. They are grown in a laboratory but are identical chemically, physically and optically to natural gems. The mineral composition of lab-created stones is created through a process similar to what nature does beneath the earth over millions of years, but in a lab at a fraction of the time, and for a fraction of the cost of mining.
The average person would be hard-pressed to tell the difference between a natural and lab-created stone. It takes a trained eye, high magnification and other instruments. The main distinction is natural gems typically have inclusions from the crystallization process — gases and other minerals mixing during the molten stage of stone creation. Because lab-created stones rely on a steady, controlled process of applying minerals, heat and pressure, they usually have fewer inclusions.
So you get high-quality lab-created stones, and their prices are significantly lower than their natural gemstone counterparts. In addition to getting a rare, top-quality fine gemstone look for less, many consumers are attracted to lab-created stones for other reasons. Environmentally speaking, lab-created stones do not tax natural resources the way the process for natural gems does — no mines are dug, the labs use a fraction of the utilities and resources necessary for a mining operation and leave behind less pollutants.
