We work everyday to make the jewelry industry more conscious, clean and circular with our ethical fine jewelry brand. We want to give consumers the opportunity to make conscious choices when purchasing a jewel.

Lab Grown Diamonds

Our choice

Lab grown diamonds have essentially the same chemical composition, crystal structure, optical and physical properties of diamonds extracted from mines. The only difference is their point of origin: in the ground for a mined diamond, above the ground for a lab grown diamond.

Real like mined diamonds, but with less impact on the planet and the people who work to produce them. Our diamonds are sustainably created on the surface using cutting edge technology that replicates the natural growth process of diamond in a laboratory. Our trusted supplier uses green energy in order to produce diamonds in the most responsible way.

Why choose created diamonds?

  • Graded just like mined diamonds (using the 4C’s: Colour, Clarity, Cut and Carat) and can be set in any type of jewelry.
  • A responsible choice, as our diamonds come without ethical issues surrounding the natural diamond mining industry.
  • Created with the least environmental impact, they don’t pollute our water bodies or displace our soil.
  • Offer excellent value and are more affordable than natural diamonds of comparable size and quality.

Diamond certificate

Lab grown diamonds are graded and certified like mined diamonds. All our diamonds over 0.50cts are verified for quality and origin features through the International Gemological Institute (IGI) or the Diamond High Council of Antwerp (HRD) with an official certificate.

Recycled Gold

Responsible origin

As part of our commitment, we only work with 18k recycled solid gold to reduce the social and environmental impact caused by the extraction of this metal and contribute to a circular consumption.

Our jewelry is made from recycled gold verified by the standard CoC (Chain of Custody) of the RJC. Our solid gold is recovered from old pieces which are melted to give them a new life in the form of yellow, rose and white gold.

All white gold pieces have a rhodium finish that gives them more shine and durability.

Why Mining is NOT our choice?

  • Water pollution and environmental devastation
  • Poor safety standards for workers
  • Inhumane labor practices
  • Rights violation of indigenous peoples
