From luxurious marble to earthy stones and raw metals, 2025’s interior design landscape is being shaped by bold materials that make a statement.
Lo & Co Interiors, known for their designer handles, have analysed international sales data and identified a significant surge in demand for three standout materials in interior design over the last six months: Viola Calacatta marble, travertine and tumbled nickel. With almost two-thirds of the brand’s sales driven by interior designers and architects, these materials are not only trending but are also defining the future of contemporary design.
Interior designer and co-founder Teegan Cocchiaro, offers her expert insight into how readers can seamlessly incorporate these luxurious materials into their own homes to achieve the high end, curated look that’s capturing the attention of designers worldwide.
Viola Calacatta marble: +340%
Marble has long held its place as one of the most beloved materials in interior design, but specifically Viola Calacatta marble is experiencing an unprecedented surge in demand, seeing a +340% rise in sales over the last six months.
Teegan shares: “We are seeing designers increasingly pairing Viola Calacatta with other bold marbles like Rosso Levanto and Verde Alpi, either in stacked installations or across adjacent surfaces, to create mood and movement. This rise in layered stonework reflects a broader return to Italian-inspired maximalism, where vibrant veining and saturated hues bring energy and individuality to contemporary interiors.
“Beyond traditional applications like benchtops and splashbacks, architects and designers are using Viola Calacatta in more innovative ways, featured in sculptural basins, integrated bathroom elements and even custom-designed furniture, allowing for a bold, cohesive design narrative throughout the space.”
For those looking to incorporate Viola Calacatta, Teegan advises:
“Use Viola Calacatta in spaces that benefit from contrast. Let it play off softer, more textural elements like timber, travertine, or brushed metals to give the marble room to breathe and make its statement.”
The marble’s dramatic purple veining makes it ideal for those embracing a more layered, maximalist aesthetic. It can be the hero of a space or a striking accent in a more neutral setting. The beauty of maximalism is that there’s no rulebook: you can pair multiple marbles, layer textures, and mix warm and cool tones to create something uniquely personal.
Travertine: +125%
With a rise in demand of over 125% in the last six months, travertine is proving its resurgence within contemporary interiors. Once associated with Roman architecture and classical ornament, today’s designers are reinterpreting this ancient stone through a modern, minimalist lens.
Teegan explains: “We are seeing Interior designers increasingly turning to travertine because it offers a calm, organic foundation for contemporary spaces. Its muted palette and natural texture work beautifully with the layered, tonal interiors we’re seeing more of, especially in coastal and Scandi-inspired projects. Beyond benchtops and vanities, we’re now seeing it used across entire floors, feature walls, and custom basins, where its subtle variation and sculptural quality can be fully appreciated.”
Teegan shares her styling advice when it comes to using Travertine: “Don’t be afraid to use travertine in larger quantities. Its organic ageing and subtle tonal variations allow it to blend effortlessly without feeling heavy or monotonous.”
Its soft, earthy tones pair beautifully with natural materials like warm timbers, linen, and leather, creating a grounded, organic aesthetic. For added depth, combine it with brushed metals such as tumbled Brass or aged bronze, to bring out the stone’s subtle variation and natural patina. Whether used in flooring, wall cladding, or bespoke furniture pieces, Travertine offers a versatile and enduring elegance that suits both classic and contemporary spaces.
Tumbled nickel: +60%
Tumbled nickel is emerging as the quiet hero of contemporary interiors, with sales surging by +60% in the last six months. Cool-toned gently textured, and unmistakably tactile, it offers a softened alternative to traditional polished finishes, bringing an industrial-meets-organic sensibility into play.
“Tumbled nickel has become increasingly popular for its imperfect, aged appearance, which makes it a perfect fit for both brutalist and industrial interiors. But what’s driving its rise is its ability to seamlessly integrate into more refined, layered designs where texture and depth are essential. As part of the broader trend toward embracing organic materials, tumbled nickel is often paired with stone, timber, linen, and other raw finishes that gain character over time.”
Teegan shares how to incorporate tumbled nickel into your interior:
“The finish is best combined with soft architectural forms, rounded edges, and muted tones to avoid the overly industrial look,” she shares. “Think of tumbled nickel as a grounding element, it won’t dominate a space, but it will anchor it with authenticity.”
This finish works beautifully across hardware, tapware, and lighting, where its subtle patina can contrast or complement surrounding surfaces. Use it to soften more structured elements like Viola Calacatta marble, or to add quiet character to travertine, linen, or textured plaster. The key is to treat it as a layer rather than a statement, its beauty is in how it interacts with its environment, not how it stands out.
