Looking for natural polished pebbles

RFQ Description

Dear SirI am looking for companies that can provide me with the following product:Natural polished colorful pebbles with a shallow hole in it. The diameter of the hole should be 1820 mm, the Depth should be 36 mm depending on the shape of the pebble. The size of the stone should be as small as possible for the hole to be bored. (3040 mm) and flat shaped. It is assumed that the hole could be easily done by mounting an electric drill on a vertical stand With a hand lever to press the bore onto the stone. The stone must be firmly clamped to the base. The holde may be made int two staes: First using a hollow bore bit to get a clean cut around the area. Then the rest could be carved out by using a flexible cord with a rotating diamond bit. There are also diamond bits with different diameters.
