There’s a version of a kitchen island that does everything right. It anchors the room, handles daily life, and still manages to stop people in their tracks the moment they walk in. This Scottsdale home is a perfect example. The homeowners chose Harmony Gold Quartz for their island, kept the slab running on both ends in a full waterfall, and paired the whole thing with a hammered copper undermount sink that makes the design feel genuinely one-of-a-kind.
Here’s how it came together, and why this combination works so well.
What Is Harmony Gold Quartz?
Harmony Gold Quartz is an engineered quartz surface built on a bright white base with warm, organic veining in soft gold and cream tones. The movement in the stone is deliberate but restrained, enough to read as natural from across the room without overwhelming a kitchen that has other things going on visually.
As a quartz product, it brings real practical advantages to a kitchen island: non-porous, stain-resistant, and no annual sealing required the way natural marble or granite would need. For a household that actually uses their kitchen, that matters.
The gold veining also gives it unusual warmth for a white surface. A lot of white quartz options read as cold or clinical in real-world lighting. Harmony Gold doesn’t have that problem. The veining keeps it from feeling stark, even in a space with cool-toned cabinetry.
The Waterfall Edge: Why It Works Here
A waterfall edge means the countertop slab continues vertically down the sides of the island all the way to the floor, rather than ending at the cabinet face. It’s one of those design choices that looks effortless in person but takes real precision to execute. The material has to be mitered and matched at the corner so the veining flows, not stops.
On this island, both ends received the waterfall treatment, which gives the piece a finished, architectural quality from every angle. Whether you’re sitting at the island, walking past from the living room, or looking in from the dining area, the stone reads as one continuous element.
The warm wood-tone island cabinets below are sandwiched by the quartz on both sides, which plays well visually: the stone frames the cabinetry rather than competing with it. The black hardware ties back to the rest of the kitchen’s finishes and grounds the look.
The Copper Sink: A Detail Worth Talking About
Not every kitchen upgrade makes people stop mid-sentence and ask about the sink. This one does. The hammered copper undermount is a single-basin design with a rich, dark patina that picks up the warm tones in the Harmony Gold veining and gives the island a personality you won’t find in most Scottsdale kitchens.
The contrast between the cool white quartz and the warm copper is what keeps the island from looking like a showroom display. The undermount installation keeps the lines clean: no lip, no interruption, just the sweep of stone and then the sink dropping away below.
The Perimeter vs. the Island: A Layered Look
Something worth noting in this kitchen: the perimeter countertops are a different material entirely, a darker and more traditional stone, while the island is Harmony Gold Quartz. This isn’t a mistake or a half-finished renovation. It’s a deliberate layering of materials that creates visual interest and hierarchy in the space.
The island becomes the focal point. The perimeter plays a supporting role. And because the island is the main workspace, sink, prep, seating, it makes sense for it to be the element that draws the eye.
If you’re working with an existing kitchen and replacing just the island, this kind of two-tone approach can actually be more interesting than a full match. It gives the space a collected, lived-in quality rather than the feeling that everything arrived in the same delivery.

Common Questions About Quartz Islands and Waterfall Edges
Is quartz a good choice for a kitchen island?
Yes, and for most households it’s a better everyday choice than marble. Quartz is non-porous, so it resists staining from wine, coffee, and cooking oils without sealing. It holds up well to daily use and is available in a wide range of styles, including designs that closely mimic the look of natural stone.
How does a waterfall island edge work?
The countertop slab is cut and mitered so that a matching piece of stone runs vertically down the side of the island to the floor. A skilled fabricator will book-match or align the veining so it flows continuously from horizontal to vertical. The result looks like one seamless piece of stone wrapping the corner.
Can I do a waterfall on just one side of the island?
Absolutely. Single-side waterfalls are common and can be a more budget-conscious approach than doing both ends. The decision often comes down to which angle of the island is most visible from your main living spaces and whether symmetry matters to your design.
Do I need to seal Harmony Gold Quartz?
No. Engineered quartz is non-porous by nature, so sealing isn’t necessary or recommended. Routine cleaning with mild soap and water is all it takes to maintain the surface.
