Product Introduction
Black Galaxy granite with gold flecks is quarried at Chimakurthy in Andhra Pradesh, India, and it is petrographically a gabbro-norite rather than a granite: the gold is bronzite, a pyroxene crystal locked into the black ground, not a coating and not a filler. That mineral fact sets the whole specification, because a bronzite fleck cannot fade, flake or rub off, and it sets the freight as well, since at 2,830 to 3,013 kg/m3 this is one of the heaviest stones we ship and a 20ft container runs out of payload long before it runs out of space.
Grade is the number that decides price, as it does on every black granite: Premium carries large, evenly spaced flecks on a uniform jet black ground with no visible lines, Good Commercial carries medium flecks with faint lines, and Commercial carries small scattered flecks and several lines, so the grade is written on our quotation and on the bundle label.

Quality Standards
Quality Control & Inspection Standards
YoYo Stone enforces a rigorous six-stage quality verification protocol for every commercial production run of white marble:
Fleck size and spread read against the grade sample
Slabs are stood up in daylight and compared with the sealed grade sample for fleck size, spacing and background depth, because Premium and Commercial are the same rock and differ only in those three readings.
01
Line and vein count
Water lines, the natural streaks that run through the body, are counted per slab, since Commercial grade is defined by having several and Premium by having none, and a line through a countertop blank is a rejected blank.
02
Cut-edge check for dye and resin
A cut face is inspected for black dye penetration and for resin-filled pits, because a dyed or resin-blackened black granite is sold into the same channel and shows itself at the first mitre or sink cutout. Bronzite flecks must run through the thickness, not sit on the surface.
03
Wet check for surface treatment
Slabs are wetted and re-read, since a sprayed sparkle finish on a low-grade black stone looks convincing dry and reads as a film when wet.
04
Gang saw cutting and calibration
Slabs are sawn on gang saw and calibrated to +/-1mm across the face, +/-0.5mm on calibrated orders, since a 20mm stone running 19.2mm shows at every joint in a 24x24 floor.
05
Products Application
Typical Project & Application Scenarios
Hotel and commercial lobby floors
Black galaxy floor tiles at 12x12 and 24x24 in a honed or leather face, because a polished black floor in a lobby records every scuff, trolley mark and dust film within a season; entrance matting is written into the specification rather than left to the client.
Kitchen countertops, island tops and bar tops
Polished Black Galaxy granite with gold flecks at 20mm and 30mm, with eased, bevelled, bullnose or mitred edges, and at 0.05% water absorption this stone takes oil, wine and coffee without a sealer programme. The polished face is the point on a countertop, because the flecks read best when the surface is mirror flat.
Stairs, risers and wall cladding
30mm treads with a honed or flamed face for grip, and slab cladding where a continuous dark ground is wanted; large-format cladding is quoted from one bundle so the fleck density reads consistently up a wall.
Bar tops and hospitality counters
A bar is the one place where the stone has to survive people rather than cooking. At 0.05% water absorption wine, spirits, citrus and coffee sit on the surface, and because this rock is a silicate gabbro-norite and not a carbonate, household acids do not etch it the way they etch a marble; the weak points on a black bar top are the resin-filled pits and the polish itself.
