How are Lab-Grown Gemstones Made?
The mineral composition of a lab-grown gemstone is made with a process similar to what nature does beneath the earth over millions of years. However, it is done in a lab in a fraction of the time and for a fraction of the cost of mining. The process for each type of gemstone starts with a slice of crystal that is cultivated for up to a year in conditions that mimic the earth's natural process. The result is a gemstone that grows much faster than it would naturally but turns out exactly the same.
Why Choose Lab-Grown Gemstone Jewelry?
The average person would be extremely hard-pressed to tell the difference between a natural and lab-grown gemstone. It takes a trained eye combined with high magnification and other instruments, and often, there is still not discernable difference. A lab-grown gemstone appears to be high quality at a price that’s significantly lower than its natural counterpart.
