We’re a full-service stone fabrication and tile installation company that handles everything under one roof in Phoenix. We take care of everything from material selection to fabrication and installation. You’ll meet our team once and work with the same trusted experts through your entire project. Our certified, background-verified team will ensure a white-glove service from project inquiry through installation.
By 2022, our reputation for precision caught the attention of The Home Depot, who invited us to lead their fabrication and installation services for the greater Phoenix area. Today, operating as Osios Corp.

We don’t just cut stone; we improve the quality of everyday living by transforming raw materials into the centerpieces of your home.
Our story began in 2021 when Brandon Ossinger founded ABR Quartz Corp. as an independent retail supplier. Recognizing a shared passion for excellence, we entered a strategic collaboration with Granum Improvements, led by the father-son duo Israel Rios Sr. and Israel Rios Jr.
This partnership was more than a business deal—it was a meeting of minds that sparked explosive growth.

Ready to start your project? Visit our 8,300 sq. ft. Design Gallery or find us through our national retail partners.
With over 60 years of combined industry experience, our leadership bridges the gap between technical engineering and artisan craftsmanship.
As a preferred installer for major big-box retailers statewide—including Home Depot, Lowe’s, Costco, and Cabinets to Go—we have the infrastructure to handle massive volume without losing the "custom" touch. Backed by background-checked technicians you can trust.
We utilize a 100% digital workflow, from templating to job completion, ensuring transparency, speed, and a perfect fit every time.
Through our 8,300 sq. ft. Xact Stone Gallery showroom, we offer a seamless retail experience featuring curated materials, tile, and cabinetry.
Visit our showroom or schedule an in-home meeting. We’ll review your project goals and cabinet layouts, help you choose a stone that fits your style and budget, and provide a clear take-off estimate. If you’d like new sink or faucet options, our team can recommend styles, finishes and brands during this visit.
After you approve the estimate and place your deposit, we order your stone and set a templating appointment. During templating, we capture precise digital measurements of every countertop edge and cutout, including sink openings and faucet holes if you’ve chosen new fixtures. Make sure your cabinets are fully installed and level before our team arrives.
When your slabs reach our Phoenix workshop, you’re invited to review the layout. We lay our digital template over your chosen stone to maximize yield, highlight favorite details and ensuring sink and faucet locations are exactly where you want them. This is your chance to confirm every detail before fabrication begins.
Over the next 5-10 days, our artisans cut each piece to spec, polish edge profiles and carve sink, cooktop and faucet openings. Our experienced fabrication team seeks to maximize material yield with precise and efficient cuts on each slab of material. We check every angle for a perfect fit, so once installation day arrives, there are no surprises.
We’ll reach out 2 to 3 days before your countertops are ready to choose an installation time that works for you. Most installs take a few hours. Larger or more detailed projects may take longer or require a second visit. On install day our crew removes your old countertops, sets and levels the new stone, reconnects plumbing, and cleans up. Before we leave, we walk through the space with you to make sure everything looks and functions just the way you expect.
Whether you’re updating on a budget or planning a one-of-a-kind statement piece, Xact Stone delivers exceptional results at a price you’ll love. Let’s build something beautiful together!
Send rough measurements or cabinet drawings through our form, or book a quick showroom visit. We’ll review your goals, talk materials and edge profiles, and give you a clear quote based on true square footage so you only pay for what you need. If you prefer, we can start with photos and a short call, then firm things up after templating.
The best material depends on how you use your space. If you cook often or have a busy household, granite or quartz are strong, low-maintenance choices. Marble looks elegant but benefits from more care. Quartzite is very hard and heat resistant. Porcelain and ultra-compact surfaces like Dekton offer durability and UV protection. Seeing slabs in person and talking through your goals will help narrow down what works best for you.
Not required, but helpful! Many people begin with a call, then stop by once they have a shortlist of colors. The showroom helps you see granite, quartz, and marble in real light and compare finishes side by side. Our team can also show sinks, faucets, and tile that pair well with your choices.
Photos, drawings or measurements, and any samples you want to match such as paint, flooring, or backsplash tile. If you already have a sink or faucet in mind, bring the model info. A few details up front help us give better design advice and a more accurate estimate.
