Shop our collection of loose man-made diamonds, available to buy online in a variety of fancy shapes, vintage cuts and carat weights. The Ethica Diamond is a fully ethical and conflict-free alternative to diamonds that is more beautiful than those sourced from the Earth. Each stone is fully certified and individually laser inscribed by the GRI, an independent grading laboratory, with a standard D-E colour, VVS1 clarity and Ideal cut.
Cut is often confused with shape, although there is a big difference between them. Before you begin your search, learn the important facts to differentiate the two.
The type of cut a stone has refers to how well it returns light. The amount of light return has to do with the geometric facet pattern of a particular stone. The closer it is to an Ideal standard, the more sparkle it will emit. The more light return, the more desirable the stone is.
Diamond shape refers to the general silhouette of a stone when viewed face up. These are the common terms you hear such as Round Brilliant and Princess. Shapes are created to suit a variety of tastes and continue to become more modern and unique. There are dozens of different styles, but only around 10 that are the most well-known.
The Ethica Diamond has all the credentials of the finest mined diamonds and laboratory grown diamonds but is far more affordable, so you won’t be compromising on quality, or your preferred stone size…
Our ethical ethos is the cornerstone of our business, and we are convinced that pricing our diamonds should be a part of this. This is why we have chosen the Ethica Diamond, which is a completely unique product that is independently certified by experts, sustainably produced and fairly priced.
