What are lab grown diamonds?
Lab grown diamonds are real diamonds created in a laboratory using CVD or HPHT technology. They are chemically identical to natural diamonds, same hardness, brilliance, and sparkle. Every House of Quadri lab grown diamond comes with IGI certification.
Are lab grown diamonds real diamonds?
Lab-grown diamonds are real diamonds with same carbon structure and chemical composition. A ‘Lab Diamond’ is exactly like a Natural Diamond, except instead of mining it from the Earth, they are grown in a lab.
They sparkle the same, have the same types of colour and clarity, and can come in the same sizes and shapes. In fact, they offer excellent value and are more affordable than natural ones of comparable quality and size.
Can anyone tell the difference between lab grown and natural diamonds?
No. Lab-grown diamonds have the same physical, chemical, and optical properties as natural diamonds. Even trained jewellers cannot tell the difference without specialized gemological equipment. They look, sparkle, and last just like mined diamonds.
Are lab grown diamonds IGI certified?
Yes. All House of Quadri diamonds are IGI (International Gemological Institute) certified, guaranteeing quality, cut, colour, clarity, and carat weight.
What is a Type IIa diamond?
Type IIa is the purest form of diamond, less than 2% of all diamonds qualify. All House of Quadri diamonds are Type IIa, making them exceptionally brilliant and pure.
Why choose lab grown diamond jewellery?
Choosing lab-grown diamond jewelry is a sophisticated decision that balances modern ethics with unparalleled brilliance. There are three primary reasons why our patrons prefer them:
1. Ethical Origin & Sustainability
Unlike mined diamonds, which can involve invasive extraction processes, lab-grown diamonds are created in controlled laboratory environments. This ensures a conflict-free origin that protects ecosystems and local communities. When you buy from House of Quadri, you are choosing a diamond with a clean, honest, and traceable background.
2. Superior Purity & Type IIa Quality
Scientifically, lab-grown diamonds are identical to mined stones but often boast fewer structural defects. At House of Quadri, many of our white diamonds achieve the prestigious Type IIa rating. This is the purest form of carbon, a distinction held by fewer than 2% of mined diamonds. This results in a stone that is exceptionally bright, clear, and visually stunning.
3. Exceptional Value & Design Freedom
Because the supply chain is more efficient, lab-grown diamonds are more affordable than mined stones of the same quality. This allows you to invest in a larger carat size or a more intricate custom ring design without compromising your budget. It is luxury reimagined—offering you more beauty and higher quality for your investment.

What Are Lab Grown Diamonds
Lab grown diamonds are real diamonds created in a controlled laboratory environment. They have essentially the same chemical composition, crystal structure, physical properties and optical properties as natural diamonds. They are not cubic zirconia, moissanite or diamond imitations.
The main difference is their origin. Natural diamonds form deep within the earth, while laboratory-grown diamonds are produced using technology that enables carbon to develop into diamond crystals. Once grown, the crystal is cut and polished into a finished gemstone.
You cannot reliably distinguish lab grown diamonds from natural diamonds with the naked eye. Specialist laboratories use advanced testing to identify growth characteristics and confirm origin. For the wearer, both offer the appearance and durability associated with diamond jewellery.
How Are Lab Grown Diamonds Created
Two established methods are used to grow diamonds in a laboratory. Both can produce diamonds suitable for fine jewellery, and the finished stone is evaluated for its individual quality.
CVD or Chemical Vapour Deposition
A small diamond seed is placed inside a chamber containing carbon-rich gases. Energy activates the gases, allowing carbon to build up on the seed in layers. Over time, a diamond crystal forms. Some CVD diamonds undergo treatment after growth to improve their colour.
HPHT or High Pressure High Temperature
This method uses high pressure and high temperature to grow a diamond from a carbon source around a seed. HPHT treatment can also improve the colour of some diamonds after growth.
The growth method alone does not determine a diamond’s beauty. Its cut, colour, clarity and carat weight all matter. Read our Diamond Education guide to understand these factors and our Special Diamond Cuts guide to compare shapes.

Lab Grown Diamond Earrings

Choosing Your Diamond Shape
Round diamonds offer a classic profile, while oval, pear and marquise shapes create an elongated appearance. Emerald and radiant cuts provide different facet patterns within angular outlines. Your preferred shape, setting and budget can help narrow down the right design.
How to Assess the Quality of Lab Grown Diamonds
The 4Cs—cut, colour, clarity and carat weight—help you compare diamonds and understand what you are buying. At House of Quadri, review the product specifications and accompanying certification for your selected piece. Our Diamond Education guide explains these quality factors in more detail.
Cut
Cut has a strong influence on how a diamond reflects light. Well-balanced proportions and careful finishing help create sparkle. Shape and cut quality are different: two diamonds with the same shape can look different because of their proportions, polish and symmetry.
Colour
On the traditional D-to-Z diamond colour scale, D, E and F are classified as colourless. The colour grade helps describe the presence or absence of colour in a diamond. Check the grade listed for your selected design when comparing options.
Clarity
Clarity describes internal inclusions and surface characteristics. VVS and VS are different clarity ranges, and the visibility of inclusions depends on the individual stone. Size, shape and the position of inclusions all affect how a diamond looks without magnification.
Carat Weight
Carat measures diamond weight rather than dimensions. A product may list the centre stone’s weight, the combined weight of all diamonds, or both. Compare these details carefully so you understand the diamond content of your jewellery.
Lab Grown Diamond Clarity Comparison
| Clarity Grade | Availability in Lab Grown | Natural Diamond | Description |
|---|---|---|---|
| IF (Internally Flawless) | Available | Extremely rare and expensive | No inclusions at 10x magnification |
| VVS1 and VVS2 | Widely available at accessible prices | Rare, commands premium pricing | Inclusions invisible to the naked eye |
| VS1 and VS2 | Standard across our collection | Common in mid-range fine jewellery | Minor inclusions are invisible without magnification |
| SI1 and SI2 | Available on select designs | Most common retail grade | Inclusions visible under 10x magnification |
At House of Quadri, VVS is our standard, not our upgrade.

| Chemical Composition | 100% pure carbon | 100% pure carbon |
| Hardness | 10 on the Mohs scale | 10 on the Mohs scale |

Frequently Asked Questions
How Do I Care for Lab Grown Diamond Jewellery
Clean gently with warm water, mild soap and a soft brush, where suitable for the complete piece. Rinse carefully and dry with a soft cloth. Store pieces separately so they do not scratch one another, avoid harsh chemicals and remove jewellery before heavy physical activity. Have the settings checked periodically to keep stones secure.
Are Lab Grown Diamonds More Affordable Than Natural Diamonds
Generally, yes. Lab grown diamonds usually cost less than natural diamonds with comparable specifications. This can allow you to choose a larger stone or a different setting within your budget. The final jewellery price also depends on gold weight and purity, diamond quality, the design and making charges.
Can I Customise a Lab Grown Diamond Jewellery Piece
Yes. Share your preferred design, diamond shape, metal option and budget with our team. We can discuss the available choices, design feasibility, pricing and expected production timeline before you confirm your order. A customised piece lets you choose details that have personal meaning.
Do Lab Grown Diamonds Have Colour and Clarity Grades
Yes. Laboratories such as IGI provide colour and clarity information for lab grown diamonds. The details depend on the report type. Review the documentation for your selected piece and read our Diamond Education guide to understand cut, colour, clarity and carat weight.
Do Lab Grown Diamonds Lose Their Shine Over Time
Lab grown diamonds do not naturally fade or lose their sparkle with age. Oils, soap and dirt can make their surfaces look dull, so regular cleaning helps maintain their appearance. Diamonds resist scratching but can chip under impact, so careful handling is still important.
Are Lab Grown Diamonds Real Diamonds
Yes. Lab grown diamonds are real diamonds with essentially the same chemical composition, crystal structure and physical properties as natural diamonds. They are grown in a laboratory rather than formed within the earth and are different from diamond simulants such as cubic zirconia or moissanite.
