1. A method of forming a diamond construction, comprising:
disposing a carbonate-based polycrystalline material in a sintering container, the carbonate-based polycrystalline material comprising diamond and a carbonate material comprising at least one alkaline earth carbonate;
placing a substrate in the sintering container, wherein the substrate comprises less than 10 percent by weight of a transition metal catalyst,
attaching an extension to the substrate, wherein the extension comprises a carbide material and a binder content of greater than 10 percent by weight; and
subjecting the sintering container and contents therein to high pressure high temperature conditions to form a carbonate-based polycrystalline diamond body bonded to the substrate.
