Is Colored Marble Real? Green, Red and Blue Stone Sinks

September 23, 20268 min read

Yes — the green, red, blue and black basins you see in stone showrooms can be real quarried marble, but a large share of what sells online under those names is not. Colored bathroom sinks fall into three very different groups: solid stone carved from a single block, crushed stone bound in resin and cast in a mold (usually sold as "cultured marble"), and pale stone that has been dyed or resin-tinted to reach a color it never had in the ground. They cost similar money and photograph almost identically. They behave nothing alike once a faucet runs over them for five years. This guide explains what each color actually is, what it costs, and how to tell the difference before you buy.

Every piece named below is in the BROSMARBLE catalog today, with the price, size and weight taken from its own product page.

Is green marble real marble?

Green stone sold as marble covers more than one rock. Some of it is calcite marble with green veining. A great deal of it is serpentinite, sold in the trade as verde antique, which is quarried, sawn, carved and polished exactly like marble and is almost always sold under the marble label. For a basin, the distinction that changes your life is not the mineralogy — it is whether the bowl is solid stone or a casting.

Our Green Marble Vessel Sink is carved from Uşak Verde Laguna, a Turkish stone, in a single piece. It measures 16.14" x 16.14" x 4.33" (41 x 41 x 11 cm) with a 1.75" (4.5 cm) drain opening, and is listed at $850. The product page records the basin at 30.6 lb (13.9 kg); crated for shipping it is recorded at 58.8 lb (26.65 kg). It is polished and sealed before it ships.

The green in that bowl runs through the full thickness of the stone, because the stone is the whole bowl. A cast resin basin carries its color in a surface gel coat a fraction of a millimeter thick. Chip a solid stone basin and you see green. Chip a cast one and you see grey filler. That is the single most useful test, and you can usually apply it from the listing alone: if a seller quotes a wall thickness, a mold, a "gel coat", or offers the same piece in twelve colors at one price, you are not looking at quarried stone.

Green also shows up elsewhere in the catalog. The Green Distressed Marble Mosaic 2x2 at $9.99 a sheet works as a backsplash behind a green basin, and the Verde Guatemala Green Marble Round Dining Table ($5,900–$9,900) is the same color family in furniture.

Is there a natural blue marble?

True blue is the rarest color in natural stone, and it is worth being blunt about that. Most basins marketed as blue marble are one of three things: a grey stone whose cool cast and white veining read as blue in photography, a genuinely blue-grey stone such as the azul-family marbles, or a pale stone that has been dyed. Saturated, even, cornflower-blue stone at a $300 price point is almost never natural.

We are deliberately literal about this on the product page. The Blue Marble Vessel Sink is carved from natural dark grey King Blue marble, and its own description says the color reads grey, blue, black and white. It measures 15.75" x 15.75" x 5.9" (40 x 40 x 15 cm), takes the standard 1.75" (4.5 cm) drain, and is $850. The basin is listed at 43.4 lb (19.7 kg), and 75.7 lb (34.35 kg) crated.

That is what a real blue-toned stone basin looks like: blue in the shadows and in the veining, grey in flat daylight. If you want a strong, uniform blue, a painted or cast basin will get you there and natural stone will not. If you want depth that changes through the day, the stone is the right answer. The Aqua Blue Marble Mosaic 12x12 at $59.99 is the same logic in tile form.

What is red marble called?

Red marble is almost always sold by quarry name rather than by color, which is why a search for "red marble sink" returns so little. The names you will meet are Rosso Levanto, Rosso Verona, Lavante Rosso and Rojo Alicante — and red travertine, which is a different rock entirely but lands in the same visual bracket.

We carry both kinds. The Red Travertine Vessel Sink is carved from natural red travertine and runs to red and brown rather than a pure red; it is a 16.14" (41 cm) round bowl, 5.51" (14 cm) high, $750, listed at 38.5 lb (17.45 kg) for the basin and 73 lb (33.1 kg) crated. The Lavante Rosso Marble Sink is the deeper, more dramatic option: Lavante Rosso marble with white veining through a red field, available from 16"W x 14"D x 6"H up to 40"W x 18"D x 8"H, as a vessel or wall-mounted, with or without a fluted front, from $900 to $4,250. Its recorded shipping weight is 110 lb (50 kg).

Red is the color where block selection matters most, because the range inside a single quarry is enormous. We pick blocks at the quarry face to keep pieces inside a usable range, but variation between basins is expected and is not a defect. If you are matching a red basin to a specific tile or paint, ask for photographs of the actual piece before it is cut — that request is free, and it is the reason our custom orders process exists.

Is black marble more expensive than white marble?

Not in this catalog, and generally not in stone. Price tracks block size, yield, how hard the stone is to carve and how much of the block is wasted — not the color. Our black marble sinks (11 pieces) start at $800 for the Black Marble Shallow Round Sink, a 15.1" x 15.1" x 2" (38.5 x 38.5 x 5 cm) shallow bowl with white veining, and the Toros Black Marble Sink is $900. That is the same band as our white, beige and grey basins.

Where black gets expensive is form, not color: the Black Pedestal Marble Sink is $3,500, because a pedestal is carved from a much larger block and is recorded at 353 lb (160 kg) delivered. Color is cheap. Volume is not.

If that form is the one you want, we have written a full guide to what a marble pedestal sink gains you and what it gives up — the plumbing rough-in, the fixed 35.89-inch height and the two formats that replace it.

Black is also the easiest colored stone to live with day to day, for one unglamorous reason: limescale and soap film dry white, so on a black basin you can see exactly where you need to wipe. On a pale beige basin you cannot, and it accumulates. Our beige marble sinks (12 pieces) are more forgiving of a knocked edge and less forgiving of a household that never dries the bowl. If the warm neutral end is where you are actually shopping, Beige Marble or Travertine? Choosing a Warm Stone Sink compares Botticino, Cappuccino and Troia and settles honed against polished.

How much does a colored marble sink cost?

Across our catalog a single-block colored stone vessel basin sits between $750 and $950, with made-to-order and wall-mounted pieces running to $4,250 as the size increases, and pedestal forms above that. The floor is set by the block, not by the color: a 16" bowl needs a block that will yield a 16" bowl, whatever shade it is.

What sits underneath those numbers is worth stating plainly, because it is where cheap colored basins make their margin. Shipping inside the United States is free on every order, to all 50 states and the District of Columbia, with no minimum. Production is 1–4 weeks on made-to-order pieces — shown as the Delivery Time on each product page — plus 3–4 business days in transit once the piece is with the carrier. Returns run 30 days, the customer pays return shipping, a 25% restocking fee applies, and returns are accepted for the full order only. For a 73 lb crated stone basin that is a real number, and it is the reason we would rather send you photographs first. The full terms are in our shipping policy and refund policy.

For the wider pricing picture across stones and sizes, our guide to what a marble sink costs in the USA breaks the numbers down by piece and by size.

Are colored sinks in style?

They are, and the reason is structural rather than fashionable. Bathrooms got smaller and vanities got simpler, so the basin became the only object in the room with any weight to it. A white bowl on a white counter has nothing to say; a green or red bowl carries the whole room and lets everything else stay quiet. That is why colored stone reappeared first in powder rooms, where there is one fixture and nothing competing for attention.

The practical rule we give designers is one colored piece per room. Pair a strong basin with plain walls, a plain counter and a warm metal tap, and let the veining be the pattern. If you want to see how that plays out, our powder room ideas and our longer piece on the return of colorful marble beyond white Carrara both work through real combinations.

Will a colored stone sink stain or fade?

Fade, no. The color is mineral, formed under pressure over a geological timescale, and daylight does nothing to it. That is precisely the advantage solid stone has over a dyed or cast basin, where the pigment sits in a thin surface layer and can yellow.

Stain, yes — like any natural stone, if you let something acidic or strongly colored sit in it. Every basin we ship is sealed before it leaves the workshop, and the sealer is a consumable: blot spills, do not let toothpaste or hair dye pool overnight, and reseal periodically. Darker stones hide the occasional etch mark and pale stones do not. The routine takes a few minutes a week and it is set out step by step in how to clean a marble sink.

One caveat specific to color: red and green stones often carry more mineral variation and more natural fissures than a plain white marble, which is part of what makes them interesting to look at. A filled fissure is a characteristic of the stone, not a crack, and it does not affect how the basin holds water.

Which colored stone should you choose?

If you want quiet warmth, red travertine. If you want drama that still reads as a bathroom fixture, Lavante Rosso. If you want cool depth without going grey, King Blue. If you want a room-defining green, Verde Laguna. If you want the piece that stays looking new with the least effort, black.

Whichever way you lean, the decision that matters more than color is solid versus cast, and an honest product page answers it in one line. Ours are carved from a single block in our own workshop in Denizli — no casting, no veneer, no resin filler — and we will send you photographs of your actual piece before it ships if you ask. Start with the vessel sink collection or the full marble sink range, and compare the stones themselves in marble, travertine or onyx and is travertine good for a sink before you settle on a color.

Frequently asked questions

Is green marble real marble?

Often, yes, but not always in the strict geological sense. Green stone sold as marble includes true calcite marbles with green veining and serpentinite, traded as verde antique, which is quarried, carved and polished exactly like marble. The distinction that matters for a basin is solid stone versus a casting. Our Green Marble Vessel Sink is carved in one piece from Usak Verde Laguna, so the color runs through the whole thickness of the bowl.

Is there a natural blue marble?

True blue is the rarest color in natural stone. Most basins sold as blue marble are either a grey stone that reads blue in photographs, a genuinely blue-grey azul-family marble, or a pale stone that has been dyed. Our Blue Marble Vessel Sink is natural dark grey King Blue marble and its own product page states that the color reads grey, blue, black and white.

What is red marble called?

Red marble is normally sold by quarry name rather than by color: Rosso Levanto, Rosso Verona, Lavante Rosso and Rojo Alicante are the names you will meet, along with red travertine, which is a different rock in the same visual bracket. We carry the Red Travertine Vessel Sink at $750 and the Lavante Rosso Marble Sink from $900 to $4,250.

Is black marble more expensive than white marble?

Not in our catalog. Price follows block size, yield and how much stone is wasted in carving, not color. Our black marble sinks start at $800 and the Toros Black Marble Sink is $900, the same band as our white, beige and grey basins. Form is what raises the price: the Black Pedestal Marble Sink is $3,500 because it is carved from a much larger block.

Will a colored stone sink stain or fade?

It will not fade, because the color is mineral rather than pigment, which is the main advantage solid stone has over a dyed or cast basin. It can stain like any natural stone if something acidic or strongly colored is left sitting in it. Every basin is sealed before it leaves the workshop; blot spills, avoid letting toothpaste or hair dye pool overnight, and reseal periodically.
