Small, Medium, Or Extra Large: Finding The Right Rockmount™ Stacked Stone For Your Project

In today’s design landscape, texture-rich materials are no longer just an accent—they’re a defining feature. Designers and homeowners alike are seeking ways to add dimension, depth, and visual interest to spaces, and one of the most versatile solutions is stacked stone. Whether applied to a modern fireplace, a rustic outdoor kitchen, or a contemporary feature wall, stacked stone panels bring beauty, durability, and a sense of craftsmanship that stand the test of time.

As one of the largest suppliers of natural stone and hardscaping products in the U.S., MSI offers an exceptional selection of Rockmount™ Stacked Stone Collections, each tailored to suit different design needs. With three distinct panel sizes—the compact M-Series, the classic Rockmount™ Collection, and the bold XL Rockmount™ Collection—there’s a perfect option for every project, from subtle backsplash upgrades to large-scale architectural features.

Here, we’ll walk you through each collection, highlight standout products, and share design insights to help you select the perfect stacked stone that enhances the natural beauty of your space.

Rockmount™ Stacked Stone M-Series – Mini Panels, Maximum Style

Sometimes, the smallest details create the biggest impact. MSI’s M-Series Mini Stacked Stone Panels measure 4.5" x 16" and are perfectly scaled for projects where full-size ledger panels might overwhelm the space. These petite panels feature some of MSI’s most popular full-size colors, allowing you to create a cohesive look when mixing panel sizes throughout your design.

Where They Work Best

M-Series panels are an excellent choice for backsplashes, accent borders, niches, and feature walls. Their freeze-thaw resistance makes them suitable for outdoor installations, including water features and exterior accent walls. Whether used indoors or outdoors, the stepped cut ends allow panels to fit together quickly, eliminating the need for grout and simplifying installation.

Featured M-Series Products:

Arctic White Mini Stacked Stone

Crafted from split-face marble, these panels feature a crisp, snowy white tone that feels both classic and on-trend. Perfect for bright, airy kitchens, spa-inspired bathrooms, or modern outdoor spaces, these mini-sized Arctic White panels deliver understated grandeur with lasting appeal.

Sierra Blue Mini Stacked Stone 

With a striking blend of deep blues, soft grays, creamy whites, and hints of rust, these split-face quartzite panels offer a captivating mix of color and texture. Their petite size and stepped cut ends make for a sleek, grout-free installation. The rich tonal depth and natural variation of Sierra Blue Mini stacked stone brings a dynamic focal point to any space, blending enduring appeal with modern versatility.

Design Tip: Use M-Series panels to add intricate detail or visual breaks in a larger design. For example, in a kitchen with a feature wall in full-size panels, mini panels can be used for the backsplash or behind open shelving to create depth and highlight focal points. Pairing minis with coordinating full-size panels helps tie spaces together without overwhelming smaller areas.

Rockmount™ Stacked Stone Collection – The Classic Choice

The Rockmount™ Collection is MSI’s most versatile and widely used stacked stone line, offering full-sized 6" x 24" panels along with coordinating M-Series mini panels for mix-and-match possibilities. Available in split-face, 3D honed, and multi-finish styles, this collection uses premium natural stones such as marble, slate, travertine, and quartzite to deliver a range of looks from rustic to contemporary.

Why It’s a Go-To Option

These panels are designed for both interior and exterior uses, including kitchen backsplashes, living room feature walls, fireplace facades, shower walls, fountains, and planter boxes. Thanks to the modular design, installation is efficient and grout lines are minimized, giving you a seamless finish that lets the natural stone shine.

Featured Rockmount™ Products:

Philadelphia Stacked Stone

Crafted from fine natural travertine, Philadelphia features a rich palette of creamy beige accented by hints of chocolate brown. Its warm, inviting tones make it ideal for living rooms, bathrooms, and outdoor seating areas. It’s a natural fit for architectural details like columns, shower surrounds, or fountain walls. Matching corners are available for a professional finish.

Marquina Nero Stacked Stone 

This dynamic split-face marble combines shades of gray and black with striking white veining, adding texture and movement to any vertical surface. Marquina Nero is versatile enough for both classic and modern spaces, making it an excellent choice for bathroom walls, kitchen backsplashes, or bold fireplace surrounds. Matching corners ensure seamless transitions.

Design Tip: Standard Rockmount™ panels excel in projects where you want strong design impact without overwhelming the room. Use natural stacked stone to anchor a space, like a fireplace wall or outdoor bar, and add textures through furniture, lighting, wall decor, and accessories. This layering creates a balanced and inviting atmosphere. Pair with minis for alcoves or smaller vertical surfaces to create cohesion.

XL Rockmount™ Stacked Stone Collection – Big, Bold, and Beautiful

When your goal is to make a grand statement, the XL Rockmount™ Collection delivers. Measuring 9" x 24", these extra-large panels provide more coverage per piece, resulting in fewer seams and a smooth, continuous look.

What Sets It Apart

Crafted from premium marble, slate, travertine, limestone, and quartzite, the XL collection features a split-face finish that ranges from refined to rustic. The larger panel size not only speeds up installation but also enhances visual impact—making them perfect for expansive accent walls, towering fireplace facades, and outdoor architectural features such as retaining walls or BBQ surrounds.

Featured XL Rockmount™ Products:

XL Alaska Gray Stacked Stone 

This luxurious marble option blends varying shades of gray with natural veining for an upscale, high-end look. Perfect indoors for elegant accent walls and backsplashes and equally at home outdoors for cladding columns or creating inviting fireplace surrounds. 

XL Alaska Gray comes with matching corners to complete each design with a flawless finish.

XL Mayra White Stacked Stone

Featuring snowy white limestone, Mayra White brings a serene allure to interiors and exteriors. Its soft, neutral palette is ideal for creating calm, cohesive spaces, whether in a natural light-filled living room or as an exterior façade accent.

Design Tip: Large-format panels are ideal for projects where you want to emphasize uninterrupted expanses of stone. In open-concept layouts, they enhance sightlines by reducing visual breaks, making walls appear longer and spaces feel larger. They’re especially impactful in double-height living rooms or exterior spaces where scale is a defining feature.

Bringing Your Vision to Life

Every space tells a story, and stacked stone helps make it unforgettable. From the compact M-Series Mini Panels to the versatile Rockmount™ Collection and bold XL Rockmount™ panels, there’s a size and style to suit any project.

With a range of colors, stone types, and finishes—plus matching corners for a seamless look—you can create designs from sleek and contemporary to warm and rustic. Indoors or out, the natural durability of marble, slate, travertine, limestone, and quartzite ensures beauty that lasts.
