Lab Grown Diamonds are created in high-tech labs. These diamonds are exquisite, pocket-friendly and are made righteously, causing no harm to the environment, just like the Earth, makes these diamonds by crystallizing carbon into ravishing diamonds. Lab grown diamonds have the same attributes as real diamonds, physically, chemically and optically. Chemical Vapor Deposition (CVD) is a process used to develop lab grown CVD diamonds.
Growing CVD diamonds relies on a unique and innovative process. In chemical vapor deposition, a thin ‘seed’ diamond is placed inside of a sealed chamber and subjected to high temperatures (generally around 1200°C to 1500°C). Then, a gas mixture is introduced to the chamber. The gases are ionized to break down their molecular bonds, allowing them to attach themselves to the diamond seed. It forms atomic bonds with the seed diamond, resulting in the growth of a new, larger diamond — completely identical to the diamonds found in nature.

A mined diamond is created deep within the earth’s crust. It takes over a billion years, immense pressure, and high temperatures for the diamond to form. With the application of advanced science and technology, it has become possible to highly accelerate this process and recreate the same geological circumstances in a laboratory above the earth.
Since the lab grown diamonds go through the same conditions as the mined diamonds, they are totally comparable to earth mined diamonds. Lab grown diamonds display exactly the same physical, chemical, and optical characteristics like Earth Mined Diamonds. The only difference is that the lab grown diamonds are engineered in a laboratory above the earth.
They may be called “synthetic,” but don’t let that term fool you. Everything, from their internal atomic structure to the way they glitter on your finger, CVD diamonds are identical to the mined diamonds that have to be excavated from the ground. CVD diamonds look exactly like so-called “Natural” diamonds. In fact, not even a trained jeweler can identify the difference. And this isn’t just the opinion of diamond manufacturers, either; in 2018, the FTC ruled that, for all intents and purposes, synthetic diamonds and natural diamonds are the same thing: 100% a diamond!
True Diamond:
Lab-grown diamonds are identical in every way to mined diamonds. They have the same chemical composition and other properties.
Conflict-Free:
Lab-grown diamonds are unaffected by political issues in war-torn areas across the globe. Their creation, cutting, and polishing processes are not compromised by global conflict.
Cost-Effective:
Our lab-grown diamonds cost less than mined diamonds. They cost a fraction of the amount compared to mined diamonds. They’re very pocket friendly.
Eco Friendly:
Lab-grown diamonds are created in environmentally friendly facilities with a tiny ecological footprint. The production process of these diamonds consumes a minimal amount of energy.
Value for Money:
Purchase a bigger lab-grown diamond at the same price you would pay for a small mined diamond.
Certified:
Lab-grown diamonds are graded by the leading Gemological lab using the same four C’s as mined diamonds.
Certification
Certification is an official document from a recognized gemological laboratory that verifies the quality and authenticity of a gemstone. It helps you know exactly what you’re buying—and ensures trust and transparency.
Earth-Mined Diamonds
Certified by top labs like GIA, IGI, HRD, and AGS. Each certificate includes the 4Cs – Cut, Color, Clarity, and Carat Weight. Often comes with a laser inscription matching the report number for authenticity.
Lab-Grown Diamonds
Also certified by GIA, IGI, or GCAL, using the same 4Cs grading. Reports will indicate the stone is lab-created, but quality is graded just like mined diamonds. These diamonds can also be laser-inscribed for verification.
Moissanite
Moissanite usually comes with a brand or manufacturer certificate (e.g., Seller own certificate), but it’s not graded like diamonds by GIA or IGI. Some brands may provide basic info like size and clarity, but not official 4Cs grading.
Cubic Zirconia (CZ)
No certification is provided. CZ is a synthetic, low-cost stone not graded by gem labs. Usually sold without reports due to its low value and limited resale potential.
Why Certification Matters
Tip: Always ask for a certificate when buying lab-grown or natural diamonds—it’s your guarantee of quality.
