Restoration of malachite tabletops
 

Is Russia an antique table with malachite tabletop. Requires restoration - partial loss of malachite layer.
Now he is in America. There is an idea not to take him to Russia, and restored on the spot.
Maybe someone knows the good and responsible restorers on a stone in North America?
Thank you for your attention!

First. that come to mind: the plastic to separate exactly the colors and slapped a hair dryer to fix. (depending, of course. "thickness, you want to restore .. millimeters to 7-9 ochent be strong, just afraid of fire, but completely invisible as the first-aid-ideal !)
 I did in the 80's imitation of malachite is easy!
