Marble fire surround and hearth (Longsight M18)

Beige colour will need a good clean. Presently has a gas fire inserted which was working but needed ignition soldering. I used a lighter to light it. Look at pics as a couple of marks but not major. Very heavy so two strong people needed. Got things for fire a few coals, grate but more will be needed, metal surround for fire got nicked.
