✦ Brazilian Translucent Blue Marble
Crystal Blue Marble Slabs
Crystal Blue Marble is a rare Brazilian calcite marble prized for its sky-blue and white crystalline pattern — the only blue-toned marble in our current collection. Polished slabs show a soft, semi-translucent glow that reads almost like frozen sea water, making it a statement material for feature walls, backlit panels, vanity tops and flooring.

Where Architects Are Specifying Crystal Blue Marble
Because its calcite structure allows some light through, thin-cut Crystal Blue Marble panels (10–12mm) can be backlit with LED panels for a soft blue glow — a popular treatment for hotel lobby feature walls, bar back walls and reception desks that want a statement piece without the fragility of full onyx.
Fabricated into vanity tops, shower surrounds and wash basins, the cool blue-and-white tone suits spa-style bathrooms and boutique hotel wet rooms. We recommend sealing at installation and resealing annually, and using pH-neutral cleaners to protect the polished surface.
Unlike onyx, Crystal Blue Marble is dense enough for full-room flooring and wall cladding, not just accent panels. Polished finish maximises the blue-white contrast for feature walls and low-traffic floors; a honed finish is the safer choice for circulation areas and wet zones.
Cut into tabletops, reception desks and indoor fountain surrounds, Crystal Blue Marble's one-of-a-kind pattern makes it a natural focal point for furniture and millwork projects, not only architectural surfaces. Each finished piece is unique — no two slabs share the same veining.

Options
Polished or Honed? Choosing a Finish for Crystal Blue Marble
01
Polished
Highest gloss, deepens the contrast between the white veining and blue base and enhances the stone’s natural translucency. The standard choice for feature walls, backlit panels and vanity tops.
02
Honed
Smooth, matte surface with a softer, cloudier blue tone and better slip resistance. A common substitution for polished in bathroom floors and higher-traffic commercial areas.
Additional finishes — including bush-hammered, tumbled, brushed, sandblasted and leathered — are available on request for project-specific orders. Ask our team for lead time and minimum order quantity.

Crystal Blue Marble vs. Pink & Green Onyx: Which Translucent Stone Fits Your Project?
| Stone | Material Type | Translucency | Best For |
|---|---|---|---|
| Crystal Blue Marble | Calcite Marble | Moderate (thin panels) | Flooring, feature walls, vanity tops, occasional backlit panels |
| Pink Onyx | Banded Onyx | High — defining property | Backlit walls, bar tops, vanity tops (not flooring) |
| Green Onyx | Banded Onyx | High — defining property | Backlit walls, bar tops, vanity tops (not flooring) |
If your project brief calls for maximum backlit drama above everything else, our onyx stone collection is the more extreme option. If you need that same translucent, one-of-a-kind character but also want to run the material onto the floor or into a working countertop, Crystal Blue Marble is the more practical choice.
Overview
The Story Behind Crystal Blue Marble's Sky-Blue Glow
Crystal Blue Marble is quarried in Bahia, a region of Brazil that also produces several related blue calcite marbles sold under similar trade names. It forms when calcium-rich limestone recrystallizes under heat and pressure, producing the dense, crystalline calcite structure responsible for both its pale sky-blue color and its faint translucency — a trait closer to onyx than to most opaque marbles.
The blue coloring is generally attributed to trace mineral inclusions within the calcite lattice, while the soft white and grey veining running through the base follows the natural fracture and re-crystallization pattern of the stone. Because the material is distinctive and much sought after, it circulates in the trade under a long list of names — Blue Crystal Marble, Calcite Blue Extra, Cristalita Ocean Blue and others. If you have been quoted a similar-looking blue marble under a different name, it is worth comparing physical samples rather than assuming an exact match, since quality and veining density can vary noticeably between suppliers.
Buying Guide
No Two Slabs Alike: Natural Variation in Crystal Blue Marble
Natural stone is not manufactured to a fixed pattern, so variation between blocks — and even between slabs cut from the same block — is normal and expected. Crystal Blue Marble typically ranges from a paler, whiter background with fine blue veining to a deeper, more saturated blue with heavier crystalline movement.
For projects that need visual consistency across a large floor or bookmatched feature wall, we recommend selecting slabs from a single production lot and reviewing bundle photos before the material ships, rather than ordering by name alone. We can supply real-time photos of the specific bundle allocated to your order on request.
Specifier Questions
Crystal Blue Marble: Questions Buyers Ask Most
Q1: Is Crystal Blue Marble harder to cut than standard marble?
Its dense calcite crystal structure makes it somewhat tougher to cut than soft marbles like Carrara. A wet saw fitted with a diamond blade, and a diamond-tipped drill bit for holes, is recommended to get clean edges without chipping.
Q2: Can hot cookware be placed directly on a Crystal Blue Marble countertop?
Natural marble has good heat resistance, so brief contact with a hot cup or pan is generally safe. We still recommend trivets or coasters for daily use, since repeated direct heat contact and thermal shock can eventually affect the polished surface.
Q3: Does the color vary between Crystal Blue Marble slabs?
Q4: Is Crystal Blue Marble translucent like onyx?
Q5: What grade is Crystal Blue Marble supplied in?
Q6: Can Crystal Blue Marble be used in bathrooms and wet areas?
Q7: What thicknesses and finishes are available for Crystal Blue Marble slabs?
