3 Reasons to Buy Lab-Grown Diamonds

  • Better for the Environment

    Lab-grown diamonds have a smaller environmental impact than mined diamonds, as they do not require the excavation and processing of earth to extract them. This can help reduce the adverse effects of diamond mining, such as habitat destruction, water pollution, and carbon emissions.

  • Budget-friendly

    Lab-grown diamonds are typically more affordable than mined diamonds, as they do not incur the additional costs associated with mining and transportation. This means you can get a beautiful, high-quality diamond at a lower price

  • Identical to Mined Diamonds

    Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds, meaning they have the same properties and characteristics. This means you can get a diamond that is just as beautiful and durable as a mined diamond but at a more affordable price.

Read the article in your language:

Lab-grown diamonds, also called lab-created Diamonds, man-made diamonds or synthetic diamonds, are created using highly advanced technological processes within strictly controlled laboratory conditions that mimic the environment under which natural diamonds form in the mantle beneath the Earth’s crust.

In recent years, awareness of ethical concerns regarding the humanitarian and ecological issues surrounding the mining of diamonds coupled with the high cost of mined natural diamonds has increased the popularity of lab-grown diamonds.

What Exactly Are Lab-Grown Diamonds, And Are They Real Diamonds?

WHAT EXACTLY ARE LAB-GROWN DIAMONDS, AND ARE THEY REAL DIAMONDS?

A lab-grown diamond is a real diamond. These lab-created gemstones are unique because they are pure carbon diamonds that display identical optical, physical, and chemical characteristics to natural diamonds. The only difference is that these diamonds are not formed through natural processes but are instead created in a laboratory environment.

Provided you purchase your lab-grown diamond from a legitimate source, there is no difference between a naturally occurring diamond and one cultivated in a laboratory apart from the origin. Many people incorrectly assume lab-grown diamonds are “fake” diamonds. In terms of structure, they are identical to mined diamonds.

What Exactly Are Lab-Grown Diamonds, And Are They Real Diamonds?
How Are Lab-Grown Diamonds Created?

HOW ARE LAB-GROWN DIAMONDS CREATED?

Two methods were developed to create diamonds within laboratory conditions. HPHT, which stands for high-pressure, high-temperature, and CVD, which refers to chemical vapor deposition. In both processes, a diamond crystal or plate is used as a seed to initiate the growth of the lab-grown diamond.

LAB-GROWN DIAMONDS QUESTIONS

+WHAT COLOURS ARE LAB-GROWN DIAMONDS AVAILABLE IN?

For those who appreciate coloured gemstones, lab-created diamonds made by the HPHT process are generally yellow, orangey-yellow, or brownish-yellow. Almost all are type IIb — rare in natural diamonds. Blue lab-created diamonds form by adding boron into the growth process. Pink and red lab-grown diamonds are less common and can be produced by subjecting the crystal post-growth to heat treatment processes involving heating and radiation. Colorless HPHT synthetic diamonds are challenging to create as nitrogen needs to be excluded from the growth process, so modifications to the growth conditions and equipment are required.

CVD synthetic diamonds are usually grayish or brownish. Adding a small amount of boron or nitrogen into the chamber will create yellow, pink-orange, or blue diamonds. Colorless crystals are easier to produce with this method, but they require a longer time to grow. Many CVD lab-created colorless diamonds available are believed to have been originally brown crystals decolorized by HPHT annealing. CVD synthetic diamonds are most commonly type IIa.

Fancy-coloured lab-created diamonds sell at comparatively reasonable prices compared to their natural fancy-colored diamond counterparts.

+ARE LAB-GROWN DIAMONDS EXPENSIVE?

A lab-grown diamond is approximately 50%-70% cheaper than a naturally mined diamond of equivalent clarity, cut, colour, and size.

While lab-created diamonds are becoming popular with those concerned about the ethical credentials of some aspects of diamond mining or are on a budget, for many, this price differential is not a great enough incentive to choose them over natural diamonds. This is particularly true for those purchasing an item of diamond jewelry as an investment.

+ARE THERE ANY ADVANTAGES TO CHOOSING LAB-GROWN DIAMONDS?

If price is a factor in your choice of gemstone, one of the most significant advantages to buying a lab-grown diamond is that it is a less expensive option. In addition, lab-grown diamonds do not usually exhibit large and visible inclusions. Therefore, if it appeals that you can purchase a flawless or nearly flawless lab-grown diamond at a lower price than a flawless natural diamond, a lab-created gem is for you.

+CAN I WEAR A LAB-GROWN DIAMOND AS MY ENGAGEMENT RING?

If you are ethically driven and want to combine quality, style, and price with your desire to protect the environment, then the option of a lab-grown engagement ring as a centerpiece is a great choice. Plus, you will not be sacrificing the look of what is possibly the most important piece of jewelry you will ever wear with a diamond engagement ring.

+WHERE CAN I BUY THE BEST QUALITY LAB-GROWN DIAMONDS?

If you have decided to buy the best quality lab-grown diamond, you would be well advised to buy your lab-created gem from a legitimate and respected diamond retailer. At Rêve Diamonds, we will provide you with certification that your choice of lab-grown diamond has been grown in the laboratory, exhibiting exactly the same composition as natural mined diamonds.
