LAB grown diamonds with Karin Parras

LAB grown diamonds with Karin Parras

“Lab-created diamonds are not fakes. They have all the same physical and chemical properties of amined diamond.” says Stephen Morisseau, a spokesman for the Gemological Institute of America, anonprofit organisation that oversees the international diamond grading system.

The first is a ’natural’ diamond, created by forces deep within the Earth. The second one wasdeveloped in a laboratory, and possesses essentially the same chemical, physical and opticalproperties as its natural counterpart. (

Both are diamonds.

When, in 1890, Japanese entrepreneur Kokichi Mikimoto created the first cultured pearl, hecultivated major shifts in the pearl industry. To this day, his brand is still ranked as one of the mostluxurious in the world.

If Mr. Mikimoto was able to create a cultured pearl industry over a hundred years ago, it was just amatter of time before the same process began to transform the diamond industry as well.

Today diamonds are undergoing the same development as pearls.

At Karine Parras, our driving question remains the same: how can we ensure our customers remainhappy and confident as the diamond market develops and transforms?Our answer is to keep growing with our customers, and continue to guarantee the quality they havecome to expect.

Since I first began dealing at the Antwerp Diamond Stock Exchange, my motto has always been,and always will be, to stand for the customer – stand for the quality of our stones, our style and ourexecution.

What exactly is a lab-grown diamond?

Lab grown diamonds are a great example of how scientists nowadays can help us make moresustainable choices.

A lab-grown diamond is a diamond: it is chemically, physically and optically identical to a mineddiamond. One is grown above ground, while the other is extracted from below. Simply put, it is areal diamond! The difference comes from its point of origin.

Naturally occurring diamonds are forged in the crushing pressure and immense heat of the Earths’mantle, around 100 miles underground. Most were formed between 1 to 3 billion years ago, at atime when our planet was much hotter than it is today.

Today, diamonds can be grown from a piece of seeded carbon in controlled laboratory conditions!Molecule by molecule, layer by layer.

Leading gemologists from the HRD, GIA, and IGI confirm that lab-grown diamonds are diamonds.

Is there a unique method to grow them?

The method used to develop diamonds in laboratories has become the new normal in the jewelleryindustry.

The key driver behind this development is time: no customer will wait a billion years for theirperfect diamond! Even then, mining rarely delivers perfect diamonds. The jewellery market issaturated with artificial goods, generating increasingly high expectations for the clarity, shape, and size of diamonds.

However, the most powerful proof of quality in the diamond industry remains valid for both naturaland lab-grown gems: no two diamonds are alike. No matter what the method.

The standard method of growing diamonds has been the High Pressure High Temperature (HPHT)system: the seed is placed in a chamber amidst pure graphite carbon; it is then exposed totemperatures of about 1,500C and pressurised to approximately 1.5 million pounds per square inch.

At the moment, the newest method is Chemical Vapour Deposition (CVD). This involves puttingthe seed in a sealed chamber filled with carbon-rich gas and heating it to around 800C. Under theseconditions, the gases begin to “stick” to the seed, growing a diamond carbon atom by atom.

In other words, hydro-powered plasma reactors, which are carbon neutral from the manufacturingpoint of view, reproduce in the laboratory the exact same conditions that form diamonds naturally. Arough lab grown diamond is grown from a small diamond seed. The diamond seed is placed in anenvironment that contains carbon, the molecular component of diamonds. After applyingtremendous pressure and very high temperatures, under highly controlled conditions, the smalldiamond seed begins to grow, emulating the natural process. The result is a rough diamond whichcan be cut and polished for use in jewellery, just like any other naturally mined diamond.

Over the past decade, this innovative technology has driven down the price of diamonds,transforming the diamond market from a ‘no-no’ business to a ‘go-go’ business

How will lab-grown diamonds affect the mined diamond market and the fine jewellery world?

Did start-up companies lead to the fall of entire industries? No. Lab-grown diamonds are the start- up of the diamond industry. Now is the time for disruptive brands!

Believe me, there is enough space for mined stones and for lab grown diamonds to coexist.

We can’t simply close our eyes to innovation, valuing only established traditions. We didn’t do it with hybrid car technologies, smart phones, or TVs – we happily accepted these alternatives as our new normal.

The 3 major diamond laboratories, GIA, HRD and IGI, provide grading reports certifying the quality of the stone, parameters and of the source being laboratory-grown.

The facts speak for themselves: lab-grown diamonds are a rapidly growing trend. Their transparency is guaranteed, and their growth on the market has been up to 20% per season. There is also huge potential for experimentation and innovation in jewellery design, thanks to their unique affordability.

Lab-grown diamonds offer jewellers much more freedom when creating new pieces. Thanks to the closely monitored growing process in the laboratory setting, the shape and size of the diamond can be easily controlled by the designer.

The future is a high-tech world, where lab-grown diamonds are accepted as the new norm. In this way, they are the perfect symbol of our modern world.

What is the most important thing about my diamond jewellery?

This is the secret about diamonds: the story of their value isn’t about their price, or whether they arelab-grown or mined. It’s emotional. It’s about memories, moments, and occasions. It’s about ourcustomers’ journey, about those moments which are enriched by diamonds. It’s for these reasonsthat diamonds keep their value for so long, well beyond our own lifetimes. And this is true of bothlab-grown and mined diamonds.

Beautiful diamond jewellery is also perfect for a new kind of customer: the self-gifting woman. Thegrowing trend of women buying beautiful items for themselves is only gaining popularity, andwon’t be going away any time soon
