Creator's note:
I conceived this ring with a vision of pure equilibrium—sleek yet striking, simple yet undeniably luxurious. Its subtly heavier band adds a quiet gravitas, departing from typical slender styles in favor of something that holds its own on the hand. The crisp, modern contours are accented by a radiant lab-grown diamond, chosen for both its luminous presence and mindful sourcing. To me, this design whispers refinement while conveying strength, an elegant statement that feels just as compelling worn every day as it does set on display.

At Formés, we honour the beauty of choice. Whether born from the precision of modern science or the depths of the earth, every diamond we offer is a reflection of conscious craftsmanship and refined values.
Lab-grown diamonds represent innovation without compromise—identical in brilliance and structure to their mined counterparts, yet lighter on the planet and fully traceable from creation to cut. They speak to those who embrace progress and sustainability without sacrificing elegance.
Ethically mined diamonds, sourced with integrity, carry with them a sense of origin—stories of earth, time, and tradition. Selected under strict ethical standards, they support responsible mining communities and the heritage of artisanal craft.
There is no single path to meaning. Only the one that aligns with your beliefs. At Formés, we are here to help you choose with intention—and wear with pride.
We say NO to mass production - in our house every jewel is responsibly made one by one to last a lifetime. We choose a holistic approach to build a culture of quality and sustainability.

We want to share these two main tips for the best care of your beloved jewelry:
1 WEAR WITH CARE. We highly recommend that you put on your jewellery after applying make up and getting dressed. We also advise that jewellery is removed before any physically demanding activities like sport, household work, swimming or gardening.
2 STORAGE. Jewellery should be stored away from direct sunlight, damp, and extremes of either heat or cold. Specially designed jewellery boxes, with soft lining and individual compartments are almost always best!

Hi, I'm Viktorija—Founder of FORMÉS Fine Jewelry.
When you don’t wear jewelry like everyone else, you see the world differently. For me, jewelry isn’t just an investment or a status symbol—it’s an expression of our inner selves and core values. I can always tell if a piece was created by passionate, happy hands or churned out by a mass-production team. There’s a certain warmth, a spark, that only comes from a loving jeweller’s touch.
As a second-generation creator with 15 years of experience, I’ve poured my soul into reimagining what jewelry can be—personal, responsibly made and always with unexpected twist. At FORMÉS, every design reflects my individual perspective and is crafted to the highest standards using innovative, sustainable methods. I hope you find a piece that resonates with your spirit as much as it does with mine, reminding you that true artistry is born from genuine passion, not just a production line.
