Biroi Jewelry Collection

Interview about Biroi Jewelry Collection, winner of the A' Jewelry Design Award 2021

About the Project

Biroi is a 3D printed jewelry series that is inspired by the legendary phoenix of the sky, who throws itself into the flames and reborn from its own ashes. Dynamic lines forming the structure and the Voronoi pattern spread on the surface symbolize the phoenix that revives from the burning flames and flies into the sky. Pattern changes size to flow over the surface giving a sense of dynamism to the structure. The design, which shows off a sculpture-like presence by itself, gives the wearer the courage to take a step forward by drawing out their uniqueness.

Your innovative fusion of architectural principles with micro-scale jewelry design in the Biroi Jewelry Collection is fascinating - could you elaborate on how your background in interior architecture influenced the creation of this distinctive collection?

My background in interior architecture shaped how I approach jewelry as spatial design. When creating Biroi, I imagined the human body as a space and each piece as an architectural object that inhabits it. This mindset helps me explore structure, rhythm, and materiality on a micro scale. Parametric tools allow me to express these ideas through fluid yet intentional forms.

The Voronoi pattern in the Biroi Jewelry Collection creates a compelling visual narrative of the phoenix's rebirth - what inspired you to choose this specific mathematical pattern to represent such a powerful mythological symbol?

Unlike rigid geometric patterns like triangles or grids, I chose Voronoi for its organic, living quality. Its fluid transitions from dense to open cells create a dynamic, flame-like surface that captures the essence of the phoenix's rebirth. It feels alive, constantly transforming, just like the myth itself. This natural flow makes it the perfect visual language to express regeneration through movement and form.

How did your journey across Tokyo, Istanbul, and Tallinn shape the cultural and artistic elements we see manifested in the Biroi Jewelry Collection, particularly in terms of merging Eastern and Western design philosophies?

Biroi began when I started my nomadic journey. Living across multiple countries taught me how to reset mentally, observe with fresh eyes, and seek patterns beyond cultural borders. Rather than drawing from local traditions, I found inspiration in architecture, especially the structural harmony of Islamic ornament and European forms. Biroi reflects this mental state: fluid, transitional, and free from fixed identity.

The transition from macro-scale architecture to micro-scale jewelry making is intriguing - what were the most unexpected technical challenges you encountered while 3D printing the Biroi Jewelry Collection, and how did you overcome them?

The biggest challenge was matching material properties with Biroi's concept. Each 3D printing material has its own limits, like minimum thickness or how it handles fine details. Nylon gave a clean surface that made the design stand out sharply, while steel showed visible print lines. At first, this seemed like a flaw, but it added unexpected texture and depth. Understanding these traits took time and testing, so finishing the first Biroi pieces was a long, trial-based process.

Could you walk us through the evolution of the parametric design formula you developed for the Biroi Jewelry Collection, particularly how you achieved consistency across different pieces while maintaining each item's unique character?

I developed a parametric rule that allows the Voronoi pattern to shrink toward a defined point on any 3D surface. By controlling this point and the density flow, I could apply the same system across multiple pieces, ensuring visual consistency. Yet each form reacts differently based on its geometry, so every piece still has a unique expression. This method gave me both freedom and structure in shaping the Biroi Collection.

The Biroi Jewelry Collection seems to transform when viewed from different angles - how did you incorporate light reflection and shadow play into your design process to enhance this dynamic visual experience?

Biroi's geometry captures and breaks light to cast delicate shadows on both the body and surrounding space. Its perforated structure lets light pass through, projecting patterns that blur the line between jewelry and sculpture. I design with this spatial interaction in mind: the piece isn't complete until it merges with its environment, especially the body. This dynamic light play reinforces Biroi's identity as wearable architecture.

Your description mentions that the Biroi Jewelry Collection aims to give wearers courage to move forward - could you elaborate on how you translated this emotional concept into physical design elements?

Biroi isn't designed as a decorative accessory. It's a bold object that claims presence. I wanted the wearer to feel like the phoenix: someone who has faced difficulty and still rises with strength. The form is unapologetically sculptural, meant to echo inner resilience. Wearing Biroi is a declaration. It's for those who move forward with courage and refuse to disappear. The design embodies that defiance through structure, weight, and form.

The development of the Biroi Jewelry Collection spanned from Kyiv to Tallinn over two years - how did this geographical and temporal journey influence the final design outcome?

Biroi began as a single necklace, not a full collection. But over two years, while moving between cities almost monthly, I kept revisiting and refining the concept. Each shift in place gave me mental distance to reassess, while Tallinn became the moment of stillness where I finalized the forms and clarified the story. The collection grew slowly, shaped by constant movement, time, and the realization that this piece held more meaning than I first imagined.

In creating the Biroi Jewelry Collection, how did you balance the technical constraints of 3D printing with your vision of creating sculpture-like pieces that maintain both durability and wearability?

For me, 3D printing removed limitations rather than adding them. Using professional services allowed me to focus almost entirely on design without worrying about mold constraints or production logistics. The materials offered both durability and comfort, which supported my vision of creating sculpture-like pieces that are still wearable. Rather than balancing trade-offs, the technology became a tool that amplified freedom and precision in my creative process.

Looking ahead, how do you envision the innovative techniques you developed for the Biroi Jewelry Collection influencing the future of architectural approaches in contemporary jewelry design?

3D printing shifts jewelry from a craft defined by technique to one open to any designer with a strong concept. It removes traditional barriers, enabling more designers to enter the field. From an architectural perspective, thinking in terms of structure, composition, and spatial context brings a new dimension to jewelry design. The scale may be small, but the design logic remains rich. I believe this fusion of digital fabrication and architectural thinking will redefine what jewelry can be.
