It’s why here at Lab.grown Diamonds, we take all the hassle out of choosing a diamond by delivering only the highest graded gemstones on the market. But more on that shortly…

So, whether you’re planning on popping the question, celebrating an important milestone or simply indulging in a piece of diamond jewellery for yourself, join us as we demystify the world of diamonds and give you the confidence to purchase quality diamonds online.


  • Lab Grown Diamonds

Frequently asked questions

Lab Grown Diamonds

  • How are lab grown diamonds made?

    Lab grown diamonds are produced in highly controlled environments that replicate the conditions which create natural diamonds. There are two methods used to create lab diamonds; CVD (Chemical Vapour Deposition) and HPHT (High Pressure High Temperature). Both methods are effective in creating high-quality, authentic diamonds, identical to those that have been traditionally mined.

  • Do lab grown diamonds look and shine like natural diamonds?

    Yes. Lab grown diamonds look and shine exactly like natural diamonds, including their ability to reflect light and sparkle! The shine and brilliance of a diamond are determined by the four Cs, cut, colour, clarity, and carat, all elements that apply to both lab grown and natural diamonds. This means that lab grown diamonds can be made inall of the same colour and look combinations as their natural counterparts. In fact, if you were to put one lab grown and one natural stone of the samespecification next to each other, it would be impossible to tell the difference between them without specialist equipment.

  • Will lab created diamonds test as real diamonds?

    Yes! As lab grown diamonds have the same chemical structure as natural, mined diamonds (carbon), lab grown diamonds are real diamonds and so will pass a diamond tester.

  • What are lab grown diamonds?

    Lab grown diamonds are diamonds that have been created in a laboratory using advanced technological processes that mimic the conditionsrequired for natural diamond formation. The diamonds created in this way have exactly the same chemical and physical properties as natural diamonds.

  • Are lab grown diamonds made of the same material as natural diamonds?

    Yes. Lab grown diamonds are made of carbon in a crystalline form, however instead of developing in a natural geological setting over thousands of years, they are made in a matter of weeks through controlled technological processes in a laboratory.

  • Can you tell the difference between lab grown and natural diamonds with the naked eye?

    No, you can only tell the difference between lab grown and natural diamonds by viewing the laser inscription on the girdle using a magnifying glass loupe. Although not all diamonds come with this, which is why it is important to choose a diamond from a trusted and experienced jeweller, as it will come with an IGI or GIA certificate. The only other way to tell the difference between lab grown and natural diamonds is by using specialist gemological equipment.

  • What is the production time of a lab grown diamond?

    The time it takes to produce a lab grown diamond can vary depending on the size and quality of stone desired. Typically, it takes from two to four weeks for a lab grown diamond to form. After the initial growth process of the rough diamond, it must then be cut and polished. The timeline for this can vary depending on its size and complexity.

  • Where are LG.D’s lab grown diamonds made?

    Lab grown diamonds are made in highly specialized laboratories where expert scientists and engineers operate cutting edge technology. LG.D partners with trusted suppliers all over the world in order to source the highest quality lab grown diamonds. Some of our partners are located in Israel, the United States, and India, however this list is always changing as we look to add to our list of highly reputable laboratories.

  • Are lab grown diamonds as durable as natural diamonds?

    The physical and chemical properties of lab grown diamonds are identical to that of natural diamonds, making them every bit as strong. They may even be stronger, as they are not subject to the same natural flaws that can weaken the integrity of natural diamonds.

    Lab grown diamonds can be subjected to much the same pressures as their traditional counterparts and are extremely resistant to damage. Natural and lab grown diamonds both sit at 10 on the Mohs hardness scale, which means they are the toughest mineral in the world. In fact, they are so durable that they can only be scratched by another diamond.

The Diamond 4C's

One of the most important things to take into consideration when buying diamond jewellery is the 4C’s. They stand for cut, colour, clarity, and carat weight. The 4C’s are a standardised system used to evaluate and describe the quality and characteristics of a diamond, and the higher grade these four features are, the more expensive the diamond is likely to be.

The most well-known of the diamond 4C’s is carat weight. Carat weight refers to the size of the diamond with one carat equalling 200 milligrams. Larger diamonds are typically more valuable, but keep in mind that a larger carat does not always mean a better quality diamond, as cut, colour and clarity should also be taken into account.

The cut of a diamond is how well the gemstone has been shaped and faceted. A well-cut diamond will have a wonderful brilliance and sparkle, and it largely determines the stone’s overall beauty. The cut grade takes into account aspects like the diamond’s proportions, symmetry and polish. It’s worth noting that cut grade is only available on round brilliant cut diamonds and is based upon a five-point scale ranging from Excellent to Poor.

A diamond’s quality is also largely based on the colour. Diamonds can go from being completely colourless to having visible hints of yellow or brown. The less colour a diamond has, the more valuable since colourless diamonds allow more light to pass through which in turns grants a brighter sparkle. Diamonds are graded on a scale from D (colourless) to Z (light yellow or brown).

Finally, a diamond is also graded on its clarity. Clarity denotes the presence of internal or external flaws, also known as inclusions or blemishes. Once again, there is a grading scale for clarity. Flawless diamonds have no inclusions or blemishes visible under 10x magnification while Included diamonds have inclusions and blemishes visible to the naked eye. Diamonds rated Flawless or Internally Flawless are typically more valuable.

When buying a diamond, it is essential to consider how its cut, colour, carat weight and clarity will affect its overall appearance. You may find that some factors are more important to you than others which will help you find the perfect diamond for your preferences and budget.


Diamond Certificates

When buying a diamond from a reputed retailer, always make sure it comes with an official diamond certificate. A diamond certificate, also sometimes referred to as a diamond grading report, is a comprehensive assessment of a diamond’s attributes and confirms vital information about its quality.

A diamond certificate serves as verification of authenticity and assures the buyer they are getting what they paid for. It details the diamond’s 4C’s (cut, colour, clarity and carat weight) and verifies its unique characteristics. The impartial evaluation is issued by independent gemological laboratories staffed with highly trained professionals who examine the diamond without any bias.

The two best-known gemological laboratories include IGI (International Gemological Institute) and GIA (Gemological Institute of America). We highly recommend ensuring your diamond arrives with a certificate issued by one of these institutes.


Reputable Retailers

Our final piece of advice for buying diamond jewellery involves the retailer themselves. We highly recommend looking for a reputable retailer that has plenty of experience dealing with diamonds and prides themselves on diamond quality and customer care.
