Learn about Lab grown Diamonds

What is a Lab grown diamond ?

Lab-grown diamond technology for industrial uses has been around for over 50 years, but within the last decade there have been impressive developments in quality and price, meaning these lab-grown stones can now be used in jewelry, too. Altering the “recipe” in the lab also means that lab-grown diamonds are available in different colors, including beautiful blues and pinks.

Are Lab grown diamonds real ?

Laboratory-grown diamonds and natural diamonds both consist of pure carbon in the same cubic crystalline form. The difference between lab-grown diamonds and natural diamonds can be distinguished by an expert using a high-tech machine—but not by the naked eye.

What’s The Difference Between Lab-Grown Diamonds And Natural Diamonds?

How Are Lab-Grown Diamonds Made?

It all starts with a seed. Made from a tiny lab-grown diamond, the seed follows one of two processes: CVD or HPHT. Chemical Vapor Deposition, or CVD, takes the seed and puts it into a plasma reactor chamber where a mix of carbon-rich gasses are added at very low pressure. Microwaves are then introduced to heat the gasses and generate plasma. As the temperature climbs over several thousand degrees, the gas molecules break apart, making way for carbon atoms to bond to the seed one layer at a time.

The High Pressure High Temperature (HPHT) method mimics the conditions of natural diamond creation by placing seeds in a large mechanical press and applying extreme pressure and high temperature to the carbon that is present. The seed acts as a guide for the lattice of carbon (that will soon become the diamond) to grow layer by layer within a matter of days until the desired carat weight is achieved.

Can You Tell The Difference Between Lab-Grown Diamonds And Natural Diamonds?

Yes. The difference between lab-grown and natural diamonds can always be detected by a diamond expert with specialized technical equipment.

When purchasing Lightbox lab-grown diamond jewelry on our site, the quality is guaranteed by the presence of a tiny inscription. Because Lightbox lab-grown diamonds have the same sparkle and visual characteristics as a natural diamond, the presence of this inscription makes it easier to identify lab-grown diamonds larger than 0.2ct and confirms that the stones were manufactured by Lightbox and meet their high quality standards. This inscription is invisible to the naked eye but it can easily be seen with a 10X magnifying loupe.

Are Lab-Grown Diamonds Priced Differently Than Natural Diamonds?

Unlike the price of natural diamonds, which is determined by a stone’s unique characteristics and rarity, lab-grown diamonds can be priced uniformly per carat. Lab-grown diamonds also have the benefit of being priced significantly lower than natural diamonds since their production capacity is unlimited.
