Comparing Lab vs Mined
Price
Our comparison prices are derived from a careful analysis of how we source and acquire our diamonds compared to the typical sourcing and pricing of mined diamonds. We keep the metal prices stable among all comparisons, only the stones are taken into the comparison calculation. While prices may fluctuate over time, we continuously monitor these trends to give you the most accurate data we can find.
Value
Guaranteeing an ethical diamond is priceless, however in terms of monetary value, traditional mined diamond jewellery retains a resale value of just 20-60% of its original price - that's if you find a buyer.
Our focus is on you wearing and enjoying your piece, so opting for lab diamond jewellery allows you to allocate your savings elsewhere while still keeping your cherished piece forever.
The 5 Cs
Of All Diamonds
CERTIFICATE
Lab-grown diamonds are indeed certified and graded by reputable institutes like the International Gemological Institute (IGI) or the Gemological Institute of America (GIA), just like their mined counterparts. The reports for lab-grown diamonds are comprehensive and include all the same essential information found in certificates for mined diamonds, such as carat weight, clarity, color, and cut. This certification process ensures transparency and quality standards for consumers when purchasing lab-grown diamonds.
CARAT
Carat refers to the weight of a diamond, with one carat equaling 200 milligrams. It measures the size and scale of the diamond.
CUT
The cut of a diamond determines its sparkle and brilliance. A well-cut diamond reflects light beautifully, enhancing its overall beauty.
COLOUR
Diamond colour refers to its lack of color, with the highest grade being D (colourless) and descending through the alphabet. Less colour means more brilliance.
CLARITY
Clarity assesses the presence of imperfections or blemishes within the diamond. Higher clarity grades signify fewer flaws, resulting in a clearer and more valuable diamond.
