What makes an engagement ring ethical?
Ethical engagement rings are those that create a low impact on the environment and don't violate any human rights. For example, lab-created diamonds have the same physical, chemical and optical properties as mined diamonds without any of the negative environmental impact.
Many jewellery companies also source recycled or fair trade gold for eco brides and grooms. Plus, there's always the option of a vintage, second-hand ring from places such as Etsy.
What is the most ethical stone for an engagement ring?
It is hard to know with any certainty exactly which stones are the most ethical since it depends on the origin and the working conditions. However, there are many companies that are doing their best to offer customers conflict-free or synthetic stones, including Grown Brilliance, Brilliant Earth, Catbird, Pandora and more.
Create a bespoke ring at Taylor & Hart, a company that ensures all of its rings are made with ethically sourced diamonds. We've got our eye on this oval diamond ring with fishtail pavé diamonds.
