Another important factor is the consistency of color and pattern across the slab; higher-grade quartz offers more uniformity, while lower grades may have noticeable variations or imperfections. These elements combined determine whether quartz is considered low, mid, or high grade.
The thickness, color hues, percentage of resin, and percentage of quartz minerals in the slab determine the grade of the countertop. Choosing a good grade ensures that a homeowner's countertop will stand the test of time.
Second choice is the lowest grade of quartz quality, commonly called builder's grade. This grade is typically used in new construction homes and apartments due to its affordability. Builder's grade quartz is mass-produced and lacks the unique patterns and colors that higher grades offer.
The real difference though is in the patterns. Expensive quartz tends to have nicer patterns that look amazing, cheap quartz tends to have basic patterns that don't look as nice.
Corian is cheaper than quartz upfront. You can expect to pay between $40 and $65 per square foot for Corian while quartz starts at $40 and can extend well beyond $200 per square foot.
To verify real quartz, use a steel knife to scratch the surface. Steel ranks around 5.5 on the hardness scale, so it can't easily damage quartz. Genuine quartz results in black lines, which are traces of steel since it's softer than quartz. On the other hand, faux quartz will result in white lines.
quartz classification
two forms: (1) alpha-, or low, quartz, which is stable up to 573 °C (1,063 °F), and (2) beta-, or high, quartz, stable above 573 °C. The two are closely related, with only small movements of their constituent atoms during the alpha-beta transition.
One of the most important is the brand and manufacturer. Reputable brands that use better-quality materials and have strict manufacturing standards will typically produce high-quality quartz countertops. Another factor to consider is the thickness of the slab – thicker slabs are generally more durable and long-lasting.
The cost of a good quality quartz countertop ranges between $50 to $65 per square foot, while that of better quartz countertop quality ranges between $65 to $75. Therefore, if you are looking for the best quality quartz countertop, you're likely to spend between $75 to $150 per square foot.
First Quality: This level utilizes the most premium Quartz. With this Quartz grade the countertops will offer rich colors and very minimum veins.
Real clear quartz may have inclusions that make the inside of the crystal appear scratched or foggy, while fake glass quartz may appear completely perfect. Some inclusions can't be seen with the naked eye. Try putting your crystal under a microscope to see if you can spot any imperfections.
To determine if it's a legitimate quartz material, use a steel knife to draw on the surface. Genuine quartz will leave behind black lines (traces of steel), while a faux one will reveal white marks, indicating low hardness. The white lines appear because the plate isn't as hard as steel.
Poor quality materials: Knock-off quartz countertops are often made with lower-quality quartz or even recycled materials. This can lead to countertops that are more prone to chipping, cracking, and staining.
Durability and Resistance
High-quality quartz is resistant to scratches, stains, and heat, making it an ideal surface for kitchens and bathrooms. To test the durability of quartz, you can perform a simple scratch test by using a sharp object on an inconspicuous area of the countertop.
In general, good quality quartz should be easy to clean (warm water and soap) and you should be happy with how it will look after tossing your keys etc on it. If they both perform the same, and you like both patterns, go for the cheaper option!
To give you an idea of the range: Samsung quartz tends to be among the most affordable options, with prices hovering between $50 and $60 per square foot. On the higher end, Corian quartz can range from $60 to as much as $100 per square foot. It all really depends on the specific brand and quality you're after.
But here's where a quartz countertop cost analysis can get a little tricky: You typically have to buy the whole slab, Bakes explains. In the rare case that the supplier and fabricator are the same party, you might be able to get the material priced by the square foot.
While quartz may have a higher upfront cost than some materials, its durability, low maintenance, and aesthetic appeal offer long-term value, making it a cost-effective choice in the long run.
Another important factor is the consistency of color and pattern across the slab; higher-grade quartz offers more uniformity, while lower grades may have noticeable variations or imperfections. These elements combined determine whether quartz is considered low, mid, or high grade.
Higher-quality quartz countertops are generally made from a higher percentage of natural quartz, which makes them more durable and resistant to wear over time. In contrast, lower-end quartz countertops may contain a higher proportion of resins or fillers, making them less durable and prone to chipping or discoloration.
Quartz stone for countertops come under different brand names, and each brand is unique in terms of style, color, and designs. However, they do have some important commonalities. All engineered quartz countertops have undergone the same process: the patented Bretonstone technology developed by Marcello Toncelli.
High-Grade Quartz Countertops
High-grade quartz, also known as designer grade, stands out for its striking resemblance to natural stone. These countertops feature deep, clear colors, complex patterns, and high levels of translucence.
Despite its variable appearance, Quartz' hardness (greater than that of glass or most metals) and lack of cleavage make it relatively easy to distinguish from other minerals. Ancient Greeks called quartz 'krystallos', which means 'ice', a reflection of the clarity of quartz' clear transparent crystals.
