Understanding the 4C's of Lab-Grown Diamonds

Understanding the 4C's of Lab-Grown Diamonds

When it comes to purchasing an Engagement Ring there are 4 C’s that are assessed to determine the quality and price - colour, cut, clarity, and carat size. If you are new to the world of diamonds, this can seem pretty overwhelming. Don’t worry, we’ve broken it down for you. 


The Gemological Institute of America (GIA) grades diamonds on a scale from D (colourless) to Z (light yellow or brown). Diamonds in the D to F range are considered exceptionally rare and valuable due to their lack of colour, allowing them to reflect light with unparalleled brilliance. At Theadore + Co., we only offer cultured Moissanite stones that are colour graded D, and Lab Grown Diamonds that are colour graded D/E/F, to give you that diamond-like effect.


The cut of a stone is like its personality - it determines how it interacts with light and how it captivates the eye. At Theadore + Co., we offer a range of different cuts from the classic Round Solitaire to the sleek lines of an Emerald Solitaire. With each cut designed to showcase the stones beauty, you won’t struggle to find the perfect cut for you and your style. 


Clarity refers to the presence of internal and external flaws, known as inclusions and blemishes, within a diamond. GIA grades diamonds by the number, size, and placement of flaws and inclusions. The more noticeable they are, the lower the diamond will be graded. At the top of the scale, though not at the very top, are VVS1 diamonds. Theadore + Co., source VVS1/VVS2 clarity moissanite and lab grown diamonds as they are considered to have excellent clarity. 


Size matters, but so does quality. Our collection offers a range of carat sizes that fits within your budget and personal style. Our moissanite and lab-grown diamonds offer excellent value for your investment, allowing you to achieve your desired carat size without sacrificing on brilliance or integrity. Whether you're drawn to the delicate sparkle of a smaller stone or the breathtaking impact of a larger one, you can trust that every stone in our collection is a testament to craftsmanship and quality.
