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 18-20 mm, the Depth should be 3-6 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. (30-40 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.
