Diamond Granite

During our independent research, we found that Diamond Granite offers countertop fabrication using most of the popular types of natural and engineered stone available in the US. The most commonly used materials include engineered quartz, marble, granite, quartzite, soapstone, and onyx — these are the materials most frequently chosen by Diamond Granite’s clients in Clinton, MI for kitchens, bathrooms, outdoor areas, and commercial spaces in 2025.

If a client requires a less common material, the desired stone is ordered from a supplier, allowing the project to meet the customer’s specific requirements. This approach enables the company to complete both standard and unique designer projects.

As part of our independent research, we attempted to determine whether Diamond Granite has its own natural stone countertop fabrication facility. Our analyst contacted the company as a mystery shopper, but unfortunately, we were unable to obtain a clear answer — the calls and messages either went unanswered or did not provide the necessary information.

The absence of confirmed data about fabrication should not be seen as a negative sign. In our experience, it is not uncommon for companies to miss some incoming inquiries or choose not to disclose such details during initial contact.

According to our research, Diamond Granite does not offer a veteran discount — this information was provided by a company representative during a conversation with our mystery shopper. However, like most companies in our rating, Diamond Granite may offer personalized terms and discounts on countertop fabrication — especially during national holidays, seasonal promotions, or for large-scale projects.

We recommend confirming the details directly: submit a request, call, or message the company through our website — and be sure to ask about any available discounts. In many cases, contractors are open to discussing individual terms.

Unfortunately, as part of our independent research, we were unable to obtain pricing information from Diamond Granite. Our mystery shopper attempted to contact company representatives to request a quote for the fabrication and installation of a stone countertop measuring 83.4 square feet. However, they were either unable to reach anyone by phone, or never received the promised estimate after the initial conversation.

We want to emphasize that the lack of response or data does not necessarily reflect the quality of the company's work. In our experience, some contractors are simply unable to respond to all inquiries in time or prefer to discuss pricing only in person.
To get accurate and up-to-date pricing for your project, we recommend reaching out to the company directly through our website — submit a request, call, or message them — and ask for a personalized quote.

According to the results of our independent research, Diamond Granite from Clinton, MI quoted a turnaround time of 35 business days for the fabrication and installation of a stone countertop. Acting as a mystery shopper, our analyst contacted the company with a request to produce and install a 83.4 sq. ft. stone countertop.

It’s important to note that the timeframe provided to our mystery shopper may differ from what you’ll be quoted, as turnaround time depends on many factors — including the complexity of the project, the material selected, and the company’s current workload.
We recommend confirming the actual timeframe directly by submitting a request, calling, or messaging the contractor through our website.

According to our research, Diamond Granite in Clinton, MI prepared the project estimate within 35 days. After a phone conversation, our mystery shopper sent a quote request to the company representative, based on a completed 83.4-square-foot countertop project, and received a detailed estimate for the fabrication and installation. This turnaround time allowed us to classify the company in the category with a very slow quote preparation speed.

Please note that estimate preparation times may vary depending on the company’s current workload, the complexity of your project, and the selected material. We recommend submitting a request, calling, or messaging the company through our website to receive a personalized quote and clarify the current turnaround time.

Yes, like most professional contractors in the market, Diamond Granite 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.

According to our information and industry practice, Diamond Granite, 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 Diamond Granite in any convenient way on this page to get the current terms.
