Natural Black gravel - clean grade, true colour.
Specify it for
Pathways, Borders, Dry gardens, Drainage strips
We would steer you elsewhere for
Barefoot areas and decorative beds where a rounded pebble is more comfortable and better looking.
How it reads
At a distance
An even mid-grey with no strong cast — the most genuinely neutral surface in the range.
Close up
Soft mineral movement rather than banding. Enough to look like stone, not enough to become a pattern.
Through the day
Shifts subtly cooler in north light and warmer under lamps, which is why it works in both.
When wet
Darkens a shade or two and returns as it dries.

Stoneza — Anantay Exports Pvt. Ltd. — is a quarry-direct manufacturer, processor and exporter of Natural slate, operating from Bhilwara, Rajasthan since 1992. We operate quarries at Bijolia, Kota and Asind alongside verified direct quarry networks across India, processing and calibrating every order through our in-house factories in Bhilwara with zero middle trader markups. We supply pan-India and export worldwide.
Send the quantity, the finish and thickness you need, and the delivery location. We come back with a firm quarry-direct quotation and a confirmed lead time. Thickness and finish options are confirmed at quotation stage. Because we quarry and process ourselves, the quotation comes from the works rather than through a trader — and we would rather quote against a real drawing than hand you an indicative range that changes later.
Natural Black Gravel is the quarry and trade name; Natural Black Gravel is our name for it. The spec code is STZ-GV-NABL. Quote the spec code on a BOQ rather than either name — the same stone is sold under several names across India, which is exactly how substitution happens on site after a specification is approved.
Machine-crushed to sharp, interlocking faces. Angular material locks together underfoot instead of rolling, which is what makes it walkable. Crushed and then screened to a single size grade. The angularity is the point — it is what allows a gravel surface to be compacted and walked on. Wet grip: high — suits wet areas. Compacts and stays put. The correct choice anywhere feet or tyres cross.
Rake level occasionally and top up every few years. No other maintenance.
Size: 5 - 10 mm graded. Thickness: Not applicable. Supplied jumbo bags / loose by tonne per project requirement. Custom sizing is available on project orders — send the setting-out and we will cut to it.
Compacted over base with edging. Joint: Not applicable. Settle the substrate and the fixing detail with your consultant at design stage rather than on site — it is the single thing most often left too late, and on a stone job it cannot be adjusted afterwards without taking the work down.
Yes. At < 1% (very low) water absorption and 2700 kg/m³ density it is exterior grade. At under 1% absorption it needs no sealer and handles monsoon and wet areas without difficulty.
Yes. We export worldwide from Bhilwara with container loading, export packing and documentation handled in-house. Minimum order is project-based rather than a fixed count. For bulk and wholesale enquiries, container quantities and repeat programmes, send the schedule and we will quote FOB or CIF against it.
Yes, and we would rather you did. Ask for a wet sample as well as a dry one — every stone darkens when wet, some dramatically, and it is the one thing a photograph cannot show you.
