We had the pleasure of working with Black Diamond Stone LLC this past summer. We have a standard 10x10 kitchen we wanted to upgrade from basic black gray granite to white quartz. We also had a kitchenette we were adding to the basement that we wanted to match. I shopped around to lots of places and Black Diamond had the best price and service around. If you know what you want and don’t want to pay extra for a fancy showroom then Black Diamond is your go to. They have in stock counters and work with a larger supplier that you can go to for more styles. The install went great, we asked for some touch ups on a seal after everything set and they came back and made it look amazing. We are so happy with how our kitchen and kitchenette looks, it’s like a brand new house now. It’s the kitchen we always wanted! We highly recommend!

Exceptional!!
From design, resources, customer service, and install, the Black Diamond team and our experience was top notch. They were extremely helpful with design and very informative on different options. They didn’t push us in any way shape or form and were extremely patient as my wife and I were somewhat indecisive. We got to work one on one with the owners and the install crew were very professional. I HIGHLY recommend them.

Does Black Diamond Stone, LLC offer cutouts for sinks, cooktops, or other elements?
Yes, like most professional contractors in the market, Black Diamond Stone, LLC performs cutouts and countertop preparation for various components — both standard and modern. According to our findings, these services are typically included in the overall project estimate. The standard scope usually covers cutouts for sinks (undermount, drop-in, or farmhouse) and holes for faucets or other plumbing fixtures. Additional cutouts — such as for cooktops, hidden or pop-up outlets, built-in wireless chargers, or other accessories — are discussed individually at the project planning and estimating stage.
It’s important to note that while the cutouts and countertop preparation are usually performed by the company, the installation of electrical and plumbing fixtures (such as faucets, outlets, or appliances) may not be included in their scope of work and could require licensed professionals. We recommend clarifying this point when placing your order.
To avoid misunderstandings, ask for a detailed estimate with a breakdown of all services: cutout pricing, installation, and any add-on options. This will ensure project transparency and help you clearly understand what you're paying for.
What guarantees does Black Diamond Stone, LLC provide for its work?
According to our information and industry practice, Black Diamond Stone, LLC, like most participants in the ranking, provides a workmanship warranty valid for 1 year from the date of countertop installation. This period is usually specified in the contract. We do not rule out that the company may have extended warranty terms (2 years or more), however, during our research, we did not receive confirmed data from the contractor regarding the duration and scope of its warranty.
The contractor’s warranty covers defects in fabrication and installation, such as uneven or separating seams, leveling and fastening issues, detachment or sagging of an undermount sink, flaws in edge finishing and cutouts, premature failure of seam materials, and cutouts that do not match the approved design. Warranty coverage does not include damage from use (thermal shock/burn marks from hot cookware, chips or cracks caused by impacts), stains and acid etching (for marble), wear due to insufficient maintenance or lack of sealing, natural characteristics of stone (veins, micro-pores, variations in shade/pattern within tolerances), shifts caused by base deformation, or any modifications performed by third parties.
The material warranty is provided by the manufacturer or the official stone supplier. Engineered quartz brands often offer a limited “lifetime” warranty for residential properties (subject to registration and compliance with care guidelines). For sintered surfaces, typical warranty periods range from 10 to 25 years. Natural stone usually does not come with a factory warranty — its quality of fabrication and installation is covered by the contractor’s warranty. The term and scope of the warranty depend on the project and materials — contact Black Diamond Stone, LLC in any convenient way on this page to get the current terms.
