New architectures of light
The Crystals is Optimum Surfaces’ capsule collection of oversize porcelain stoneware slabs inspired by crystal, where light meets matter to become surface. Everything originates from an unseen balance of translucent textures, understated patterns, and a layering that captures and reflects light with added depth. This balance produces crystal-effect surfaces that bring light to life, reflecting brightness through the surroundings.
Alba, Luce, and Iride explore this concept with three distinct identities, each expressing a different nuance, warm and layered, pure and delicate, and intense and structured. Three different visions of white, as a dynamic material defined by translucency and a strong architectural presence.
Crystal-effect surfaces for interior design
With The Crystals, light and material are translated into crystal-effect porcelain stoneware slabs created for interior design, architecture, and furnishings. Available in one exclusive size (1840×3300 mm), the capsule collection is defined by surfaces that interact with light and offer depth and continuity, giving interiors an intense, refined, and distinctive identity.
The Crystals comes in three versions, each surface shaping the interior with its own distinctive presence. In each one, white plays a key role, amplifying light, enhancing depth, and bringing an extraordinary visual purity to spaces. The resulting material is ideal for countertops, tables, decorative walls, bathrooms, kitchens, and high-end hospitality and retail projects. Bright white materials for interiors that offer visual continuity and a striking contemporary presence.
