A lab grown diamond is a real diamond created using advanced technology in a controlled environment. It is chemically, physically, and visually identical to a mined diamond. The only difference is their origin: one takes weeks or months to form using advanced technology in a controlled environment, while the other takes billions of years beneath the Earth's surface. 

Yes. Lab grown diamonds are 100% real diamonds with the same sparkle, hardness, and durability as mined diamonds. Diamonds, whether mined or lab grown, are simply carbon atoms arranged in a crystal structure, then cut and polished into their brilliant shape. Lab grown diamonds are professionally graded by the same reputable gemological labs that grade mined diamonds.

There are two main methods:

• HPHT (High Pressure High Temperature): Simulates the extreme heat and pressure found deep underground. 
  A diamond seed is placed in a chamber and exposed to over 1600°C and intense pressure, causing carbon atoms to bond and grow into a diamond crystal.
• CVD (Chemical Vapor Deposition): Grows diamonds layer by layer from a carbon-rich gas.
  A diamond seed is placed in a vacuum chamber filled with carbon-rich gases. With high heat and ionized gases, carbon atoms slowly layer onto the seed, growing the diamond crystal over time.

Both methods produce gem-quality diamonds that are visually identical to natural diamonds.

Yes! Lab grown diamonds test as real diamonds because they have the same chemical and physical properties as mined diamonds. Standard diamond testers that measure thermal and electrical conductivity will accurately detect them as real diamonds.

Visually, no—even by trained jewelers. Lab grown diamonds are identical to mined diamonds to the naked eye and even under magnification. While standard diamond testers that measure thermal conductivity cannot distinguish between the two, advanced gemological tools that measure spectroscopy and photoluminescence can identify characteristics that suggest it may be lab-grown. 

The most reliable method to tell the difference is a grading report from a trusted gemological institute, which uses advanced techniques to determine a diamond's origin. Grading reports will clearly indicate whether the diamond is man-made. Graded diamonds will also have a laser-inscribed serial number on the girdle that is visible under magnification. Lab grown diamonds will have the term "Laboratory-Grown" or the letters "LG" preceding the report number.

Yes. All of our loose lab grown diamonds and most lab grown diamond jewelry with diamonds measuring 1 carat and above are certified by leading gemological laboratories such as GIA and IGI, just like mined diamonds, to ensure quality, authenticity, and transparency.

Yes. Lab grown diamonds cost significantly less than comparable mined diamonds. This allows you to get a larger and higher-quality stone for the same or often lower budget. The larger the diamond, the bigger the difference in cost—as much as 98%!

Absolutely. Lab grown diamonds are an eco-friendly alternative to mined diamonds. They require fewer resources, reduce environmental impact, and avoid the social and ethical concerns associated with traditional mining.

We'll be honest: no diamond is a good investment.

However, lab grown diamonds offer exceptional value and quality. While mined diamonds may "hold" a bit more of their value, they still lose significant resale value—typically at least 50% of what you paid. When you do the math, lab grown diamonds offer significant savings—no matter how you look at it. They provide a modern, ethical, and stunning choice for engagement rings, fine jewelry, and special occasions.

Lab grown diamonds are just as durable as mined diamonds (10 on the Mohs scale). You can clean them with warm water, mild dish soap, and a soft toothbrush, or with professional jewelry cleaning solutions. Make sure to rinse and dry them thoroughly. 
To maintain your lab grown diamond jewelry, avoid exposure to harsh chemicals and high-impact activities, and remove jewelry before applying products like lotions and sunscreen.
