A method for forming a diamond product. Diamond material is provided and a damage layer comprising spbonded carbon is formed in the material. The presence of the damage layer defines a first diamond layer above and in contact with the damage layer and a second diamond layer below and in contact with the damage layer. The damage layer is electrochemically etched to separate it from the first layer, wherein the electrochemical etching is performed in a solution containing ions, the solution having an electrical conductivity of at least 500 μS cm, and wherein the ions are capable of forming radicals during electrolysis. The diamond product is also described.

Method for forming diamond product

An embodiment provides a method for modifying a carbon region on a boron-doped diamond electrode surface, comprising: placing a boron-doped diamond electrode surface in an aqueous solution, wherein the aqueous solution comprises an ionic treatment solution; applying a voltage difference across the boron-doped diamond electrode surface; and modifying a carbon region on an area of the boron-doped diamond electrode surface, wherein the modifying is responsive to application of the voltage while the boron-doped diamond electrode surface is in the aqueous solution, wherein the modification continues until a desired signal of the carbon region is reached. Other aspects are described and claimed.
