Choosing the Perfect Lab-Grown Diamond: The 4 C’s
True beauty is built on integrity. At TMC Fine Jewellers, we believe luxury should never come at the cost of the world around us. By championing lab-grown diamonds and Moissanite, we honour the balance between timeless elegance and ethical innovation - ensuring every piece we create is a conscious choice for you and the future.
For those seeking a real diamond with ethical origins, our exclusive collection of lab-grown diamonds offers brilliance without compromise. These diamonds are chemically, physically, and optically identical to mined diamonds. They are one in the same - real diamonds.
We work exclusively with IGI and GIA-certified diamonds in D-F Colour, VS2-VVS1+ Clarity, and Excellent Cut, Polish, and Symmetry - each hand-selected by our Chief Gemstone Expert and Co-Founders to meet our exacting standards.
But what do these gradings mean, and how do they help you find your perfect diamond? In this journal, we’ll guide you through the 4 C’s, helping you co-create the ring of your dreams.
Cut
Arguably the most important of the four C’s, cut refers not to the shape of a cultured or ‘laboratory grown’ diamond, but the balance of proportion, symmetry, and polish. This means the quality of workmanship directly correlates with the beauty of the stone - with the cut determining the brilliance, fire and ultimately, the sparkle of your beautiful engagement ring.
Within our Signature Range we offer Oval, Round, Emerald, Radiant, Elongated Cushion, Pear, Marquise, Cushion and Asscher Cut Lab-Grown Diamonds.
To offer you simply the best of these cuts, we combine a thousand-year-old craft with modern sustainable practices and design. Proudly crafted in Australia, each of our rings at TMC Fine Jewellers is created with intention, unrivalled craftsmanship and most importantly passion - only working with excellent cut round brilliant diamonds, alongside fancy shaped diamonds that possess excellent polish and symmetry.
Colour
Colour refers to a diamond's natural colour and should not be mistaken for fire, the coloured flashes of light the diamond emits when it moves. Within the GIA Grading System, Colour is graded alphabetically from D (Colourless) to Z (Light Yellow).
We work with D and E coloured laboratory grown diamonds ensuring the brightest and best quality stones. Also known as ‘colourless’ diamonds, these divine gemstones are simply mesmerising. We also offer a range of fancy coloured lab-grown diamonds.
Clarity
Clarity refers to the inclusions found in a diamond, also known as the small imperfections found within the structure of the diamond.
Since a lab-grown diamond is created with advanced technology mimicking the natural growth process of a mined diamond, these inclusions can occur when the gemstones are exposed to metal traces utilised during the HPHT growth process or mineral inclusions from the CVD growth method.
Whilst this is something to be cautious of when sustainably crafting a lab-grown diamond above ground, it also allows better mitigation of these issues in a controlled environment.
Our lab-grown diamonds range between the VVS1-VS1 - working with only the most exquisite gemstones that deliver on our commitment of balancing quality and affordability.
Carat
Lastly, Carat is simply how much a diamond weighs, with one carat equalling 200 milligrams. The larger the carat, the larger the gemstone, and with all else being equal, the higher the cost.
Whilst lab-grown diamonds are more expensive than moissanite, ranging between $4,000.00 and $15,000.00, they are still significantly more affordable compared to their mined counterparts. This means they are a perfect choice for somebody who desires a real diamond with ethical origins and who is looking to indulge in a larger carat size.
