The 4Cs Guides for Diamonds
Diamond Carat Weight
Carat weight directly impacts the size and price of a diamond. One carat equals 200 milligrams. As the weight increases, the price grows exponentially because larger-carat diamonds are rarer. Depending on your budget and preferences, you can choose a suitable carat weight that balances the diamond's visual appeal and value.

Diamond Colour
The colour grade of a diamond ranges from completely colourless (D grade, the highest) to light yellow (Z grade). Diamonds graded D to F are considered colourless, while G to J are nearly colourless, with the colour becoming increasingly noticeable in the lower grades. Generally, the closer a diamond is to being colourless, the more valuable it is. However, diamonds with certain colour grades, such as light yellow, also possess their own unique charm.

Diamond Clarity
Clarity refers to the degree of internal and surface imperfections (known as inclusions and blemishes) in a diamond. The clarity scale ranges from Flawless/Internally Flawless (FL/IF) to Included (I1-I3). Diamonds with higher clarity grades have fewer imperfections, making them rarer and more expensive. Lower-clarity diamonds have more noticeable flaws, but they can still display beautiful brilliance in certain settings.
Diamond Cut
The cut determines the diamond's brilliance, or how well it reflects light. A well-cut diamond can maximise light reflection, showcasing a captivating sparkle. Cut grades range from Ideal/Excellent to Poor. A high-quality cut ensures the diamond has unparalleled brilliance, while a poor cut can make the diamond appear dull and lacklustre.

FAQ
About 3ct and Above Round Cut Lab Grown Diamonds
Lab-grown diamonds of 3 carats and above possess a unique charm primarily due to their impressive size and dazzling brilliance. These large-carat diamonds not only provide extraordinary visual impact but also represent the pinnacle of precision craftsmanship and advanced technology. Thanks to meticulous control in the laboratory creation process, these diamonds can achieve significant carat weights while maintaining superior colour and clarity, making them symbols of luxury.
Additionally, lab-created diamonds retain the same physical, chemical, and optical properties as natural diamonds, ensuring their beauty and durability. Importantly, these large lab diamonds are typically offered at more affordable prices, making them a high-value option. This allows consumers to enjoy the grandeur and allure of diamonds comparable to natural giants without the exorbitant costs.
When selecting lab grown diamonds of 3 carats and above, the 4Cs standards remain crucial. Firstly, a high-quality cut is essential for the diamond's brilliance. In larger carat weights, the precision of the cut significantly impacts the diamond's sparkle. Secondly, the colour grade should be balanced with personal preferences and budget; while lower colour grades are more affordable, very low colour grades might affect the diamond's appearance. It is recommended to choose at least an H colour grade to ensure the diamond appears white and clean in various lighting conditions.
Regarding clarity, even small inclusions can be more noticeable in larger-carat diamonds, so opting for higher clarity grades is safer. Selecting a clarity grade of SI1 or higher is advisable to ensure no visible imperfections to the naked eye. Lastly, while carat weight is a significant factor, it should be combined with the other three Cs to ensure overall harmony and beauty. In summary, when choosing large-carat diamonds, emphasis should be placed on the overall quality and balance of the 4Cs.
To identify the authenticity of lab-grown diamonds, one should rely on professional certificates such as those from GIA or IGI. Lab-grown diamonds share the same chemical and physical properties as natural diamonds, but they can be distinguished through professional instruments like spectrometers that examine internal structure patterns or using ultraviolet light to detect subtle differences. Additionally, lab-created diamonds often have specific markings, such as laser inscriptions, to certify their origin. Purchasing from reputable suppliers and requesting a certification report at the time of purchase are crucial steps to verify the authenticity of lab-grown diamonds.
Lab-grown diamonds often surpass natural diamonds in terms of quality. This is because the controlled conditions of lab production greatly reduce the inclusion of impurities, ensuring the diamonds' purity and colour consistency. In contrast to natural diamonds, which take billions of years to form deep within the Earth and may contain natural flaws, lab diamonds benefit from highly controlled manufacturing environments. This results in diamonds with higher clarity and superior cut quality, offering visual and technical advantages that can surpass those of traditional natural diamonds.
Lab-grown diamonds are synthesised in laboratory conditions. This process mimics the natural conditions under which diamonds are formed within the Earth, primarily using High-Temperature High-Pressure (HTHP) or Chemical Vapor Deposition (CVD) techniques.
1. High-Temperature High-Pressure (HTHP):
In this method, carbon is subjected to extreme heat and pressure, simulating the conditions found deep within the Earth's crust. Under these conditions, carbon atoms crystallise to form diamonds.
2. Chemical Vapor Deposition (CVD):
This technique involves breaking down carbon-containing gas in a chamber, allowing carbon atoms to deposit onto a substrate layer by layer, forming a diamond.
Both methods produce diamonds with the same structure and optical properties as natural diamonds, offering high-quality and affordable options.
Lab-grown diamonds, also known as synthetic or laboratory-created diamonds, are gemstones scientifically synthesised under controlled conditions, possessing the same chemical structure and physical properties as natural diamonds. Unlike natural diamonds, which are formed over billions of years through geological processes, lab-grown diamonds are produced more quickly and in an environmentally friendly manner, with lower costs and guaranteed conflict-free origins. Although virtually indistinguishable in appearance and molecular structure from natural diamonds, lab-grown diamonds offer a more sustainable and economical option.
