WHAT ARE LAB GROWN DIAMONDS?
Lab grown diamonds are grown in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust. These lab created diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure. Since they are made of the same material as natural diamonds, they exhibit the same optical and chemical properties.
How are lab-grown diamonds made?
Like earth-mined diamonds, lab created diamonds are made of carbon. While natural diamonds pulled from the earth are created over millions of years under intense heat and pressure, man made diamonds are grown fairly quickly in a lab from a single carbon seed. They using advanced technology—either CVD or High Pressure High Temperature (HPHT)—the carbon seed slowly forms into a crystalline structure.
The CVD Method
CVD stands for chemical vapor deposition.Lab grown diamond seeds are loaded into a CVD reactor. Then, a mix of gasses containing carbon is added at a very low pressure. Microwave energy is used to heat the gases and generate a plasma. When the temperatures climb over several thousand degrees, the gas molecules break apart and carbon atoms bond to the seeds, growing them one layer at a time.
The HPHT Method
HPHT stands for high pressure high temperature.This method mimics the conditions under which diamonds naturally form. Large mechanical presses are used to apply extreme pressure and high temperature to carbon in the presence of a diamond seed. The seeds act as a template for a lattice of carbon to grow layer by layer over the course of a few days.

Lab Grown Diamond FAQS
Most frequent questions and answers
Does the color of colored lab grown diamonds last ?
No. The color of lab grown diamonds is affected by whether impurities are mixed in the production process, or whether defects are created during the deposition process, and the structure is usually very stable at room temperature and does not change over time.
The lab grown diamonds that cannot pass the diamond tester are fake?
No, The third generation of diamond tester, is added to the thermal conductivity test, HPHT cultivation of diamond production requires the participation of metal catalyst, the finished product contains metal ions, with a weak conductivity, the test results will show into non-diamond. Buy lab grown diamonds can not be measured by the ability to pass the diamond tester, it is best to choose diamond with the authoritative certificate, such as IGI or GIA certificate.
How long does it take to customize a lab grown diamond ?
It is about 30-60 days for loose diamond, depend on what cutting, sizes and color you want. All custom lab grown diamonds can be issued with IGI certificates, it will take about 10 days. For lab grown diamond jewelry, it needs about 15-25 days, same as our custom jewelry.
Is lab grown diamond real ?
Yes, lab grown diamond is real diamond, are essentially identical to natural diamonds in terms of chemical, optical and physical properties and crystal structure, also the 4C standard is exactly the same. Jewelers can’t tell the difference, only a professional diamond testing agency can tell the difference
How to maintain a lab grown diamonds ?
1. To keep away from oil, If it is stained with oil, it should be cleaned with a professional jewelry cleaning solution.
2. To avoid bumping.
3. Stay away from radiation, the color of a diamond is likely to change when it has been irradiated.
4. Stay away from UV rays, If the diamond is exposed to strong ultraviolet light after ozone filtering, you can see small pitted spots on the surface of the diamond within a few moments
What are the two rarest lab grown diamond colors?
Fancy red lab grown diamonds and fancy light pink lab diamonds. Red and light pink natural diamonds are relatively rare, so the value is also higher, and the lab grown diamond of these two colors of diamonds is also difficult to produce, so the market is relatively rare.
