How to Buy Slabs

Slabs are delivered only to a licensed fabricator. Review the delivery requirements before requesting samples.

Do You Have a Fabricator?

Slabs can only be shipped to a licensed fabricator for unloading. We don't recommend shipping slabs to job sites or to non-fabricators. Before requesting samples, make sure you have a fabricator to handle your slabs.

Slabs Are Heavy and Delicate

Special care is required when shipping slabs. There are two shipping methods:

Truck with an A-Frame: Check with your fabricator to see if they are equipped to pick up the slab from our facility where it is located. Your fabricator should contact us to confirm availability and pricing before you order samples. We deliver within 50 miles of the warehouse directly to licensed fabricators only (no job site deliveries).
LTL Shipments by Crate: If your fabricator is more than 50 miles from our slab warehouse, they should ask about pricing for crating and shipping. Please contact us for crating charges and confirm freight costs before ordering slab samples.
Slabs should be handled only by the people listed above. We are not responsible for any damage or liability from slab handling.
Preparation and shipment of slab samples may take 6-9 business days.

Granite · Slab

Cosmic Black Polished Granite Slab Random is a black granite sold by quote for the full slabs a customer selects. It arrives in random sizes from the batch list, including 76x123 inch and 76x119 inch options. The stone carries a polished finish that reflects light and deepens the dark body. Pricing is determined by quote based on the exact slabs chosen. We do not list prices online because each slab is unique.

Design

Cosmic Black Polished Granite

The colour is a deep black with a speckled grain typical of granite. A polished buff brings out the mineral details in the stone. Light catches the surface differently across each slab. Variation between pieces is slight but present in every slab. The finish reads as a mirror shine that shows wear sooner than honed options.

Polished Reflection

The mirror shine highlights the speckled grain and deepens the black body.

Slight Variation

Each slab carries its own markings and size from the batch list.

Where to use it

Thirteen Slabs in Fairfax

The stone suits residential countertops, shower walls, residential interior walls and commercial interior walls. A licensed fabricator templates and installs the material after delivery. Two batches are in stock at our Fairfax, VA warehouse. Thirteen slabs are available in random sizes. Slabs from one batch match most closely because they come from the same block.

Fabricator Delivery

Slabs go to a licensed fabricator for templating and installation.

Batch Matching

Slabs from the same batch share the closest visual characteristics.

Why we chose it

Batch ConsistencyTwo batches are in stock at Fairfax, VA, and slabs within a batch look the closest.
Stocked SizesThirteen slabs are available in 76x123 inch and 76x119 inch random sizes.
Polished FinishThe polished buff reflects light and deepens the black colour of the granite.

Care

The polished surface requires less frequent sealing than marble but still benefits from a sealer in kitchens. Wipe spills promptly to maintain the mirror shine. Use pH neutral cleaners to protect the finish.
