How do I tell Coffee Wood Marble apart from other wood-grain marbles?

Look at three things: the base colour, the spacing of the lines, and whether the figure stays straight over a long run. Coffee wood is a warm grey-brown with close, evenly spaced straight lines. Grey wood grain is cooler and flatter; white wood grain is pale; pinghua has a wavy, cloud-like figure instead of lines.

Reference photographs. They show the material and the finish; they are not photographs of goods we made, and the colour on screen is not a colour-match.

The figures, and where each one comes from

Variety Base colour Figure
Coffee wood grain Warm grey-brown, deep brown Fine straight lines, evenly spaced
Grey wood grain Cool grey Straight lines, lower contrast
White wood grain Pale cream Straight lines, low contrast
Athens grey wood grain Grey with drift Finer, cloudier lines
Pinghua Warm beige Wavy, cloud-like, open figure

Why it behaves the way it does

The figure is a reading of the bed, not a photograph to be matched. In this belt the beds run in order and each has its own character — and the fourth bed down is the coffee one, which is why the quarry face carries the marks and why the block number is on the invoice.

What these figures are, and what they are not

A photograph cannot identify a block. If a supplier has sent you a sample, hold it against the sample board and read the block number, not the picture.
