This comprehensive network allows us to bypass middlemen, secure the highest quality stones at competitive values, and, most importantly, find the exact diamond that meets your vision and budget.

OUR COMMITMENT
Trust is the foundation of every diamond purchase, and our sourcing strategy is built to reinforce it. We maintain rigorous standards across all stones:
- Certification: we source certified diamonds by independent, globally recognized grading laboratories (such as GIA and IGI) giving you absolute confidence in the diamond’s quality specifications.
- Ethical sourcing: for natural diamonds, we maintain a strict policy of sourcing only ethically mined stones and fully adhere to the Kimberley Process. For laboratory diamonds, we work only with producers that follow sustainable, transparent practices.
- Traceability: the journey of every stone is documented and accountable.

BEYOND THE CUT
A diamond’s value and identity are shaped long before it arrives in our studio. Understanding this journey is key to appreciating the stone in your hand.
The diamond value chain begins at the mine, where rough stones are extracted. These rough diamonds are then sold to cutters and polishers, typically in global trading centers. Next, highly skilled cutters and polishers transform the rough stones into brilliant polished diamonds. These polished stones are then graded and certified by independent labs based on the 4Cs (Carat, Color, Clarity, Cut). Finally, the certified diamonds are delivered to our Korkeila Helsinki boutique where they are carefully crafted into fine jewellery. Each step adds skill, accountability, and value to the final product.
