All about lab grown diamonds

One of the big choices you make when you shop for fine jewelry is, “Do I want natural or lab grown diamonds?” We’ve helped lots of people make that call. In 2017, Helzberg became one of the first national jewelers to offer lab grown diamonds side by side with their natural counterparts. Here’s some information to help you decide if your dream diamond should be lab grown.

What are lab grown diamonds?

Lab grown diamonds are real diamonds that are created in a lab. Using advanced technology in a highly controlled environment, scientists successfully mimic the same process the earth uses over billions of years to create natural diamonds. From their chemical composition to the way they sparkle in the light, lab grown diamonds are identical to natural diamonds in every way. The only difference is their origin story. 

How are lab grown diamonds made?

There are two ways to create lab grown diamonds: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both methods begin in a chamber with a tiny “seed” — a piece of lab grown diamond — and end with a rough diamond. The two types of lab grown diamonds look a little different in the rough, but once they’re cut and polished only an expert with expensive equipment can tell them apart from natural diamonds.

Carbon-rich gas is heated in a CVD vacuum chamber to break it down and release the carbon particles. They attach to the starter seed in layers to form a rough diamond.

To replicate the way natural diamonds form, the starter seed is placed in a capsule with high-quality carbon. Under high pressure and heat, the carbon dissolves and crystalizes on the seed layer by layer.

THE DIAMOND 4C’S

Lab grown diamond quality

The value of every lab grown and natural diamond is determined by its unique combination of the 4C’s: cut, color, clarity and carat. Helzberg’s selection offers a range of values and price points to fit every budget.

Lab grown diamond certification

Fine jewelry is an investment, and we want you to feel completely confident about the value of your diamond. To certify Helzberg lab grown diamonds, we work with the Gem Certification & Assurance Lab (GCAL) and International Gemological Institute (IGI) because of their specific expertise in lab grown grading practices. As American Gem Society (AGS) members, we maintain quality standards that sometimes mean rejecting even diamonds certified by our grading labs.
