What are Lab Grown Diamonds ?

A lab-grown diamond is a real diamond created in a controlled environment using advanced technology. It has the same physical, chemical, and optical properties as a natural diamond.

Are Lab-Grown Diamonds Real?

Let’s clear that up: yes.

Lab-grown diamonds are not imitations—they are real diamonds with the same physical, chemical, and optical properties as mined diamonds. The difference lies in their origin. Instead of forming deep within the Earth over billions of years, lab-grown diamonds are created using advanced technology that replicates the natural conditions under which diamonds form.

Every lab-grown diamond is graded using the exact same 4Cs—cut, color, clarity, and carat— and certified by top gemological institutes like GIA and IGI. So when you choose a lab-grown diamond, you’re not compromising on quality. You’re choosing innovation, transparency, and bold new luxury on your terms.

Lab Grown vs. Natural Diamond: What’s the Difference?

Lab-grown diamonds and natural diamonds are virtually identical in appearance, durability, and
chemical structure—but they differ in origin and impact.

How Lab-Grown Diamonds Are Made

Modern alchemy, perfected.

Every lab-grown diamond begins with a spark—literally. It starts as a tiny carbon seed, often taken from a pre-existing diamond. From there, cutting edge technology replicates the Earth’s natural diamond-forming conditions using one of two advanced methods: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD)

There are two main methods:
• High Pressure High Temperature (HPHT): A diamond seed is placed under extreme pressure and heat, mimicking the natural environment of the Earth’s mantle.

• Chemical Vapor Deposition (CVD): A diamond seed is placed in a chamber filled with carbon- rich gas. The carbon atoms slowly deposit onto the seed, layer by layer, forming a diamond crystal.

Why We Choose CVD

Not all lab-grown diamonds are created equally. At Trillium, we use the CVD (Chemical Vapor Deposition) process—widely considered the most advanced technique in lab diamond creation. This method allows us to grow diamonds with fewer impurities, exceptional clarity, and a more consistent structure—giving you a cleaner, more refined stone, inside and out.
