We only use the top 1% of cultured (lab created) stones. Our lab diamonds are DEF colour and VS+ clarity. (The top of the top diamonds) or eye-clean sapphires, emeralds and rubies. Our grown stones are identical to mined stones of the same quality, the only difference is their origin. We set all of our stones on gold or platinum so your pieces will last forever.

Comparing Lab vs Mined


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.


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 4 Cs

Of All Diamonds


Carat refers to the weight of a diamond, with one carat equaling 200 milligrams. It measures the size and scale of the diamond.


The cut of a diamond determines its sparkle and brilliance. A well-cut diamond reflects light beautifully, enhancing its overall beauty.


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 assesses the presence of imperfections or blemishes within the diamond. Higher clarity grades signify fewer flaws, resulting in a clearer and more valuable diamond.
