A polycrystalline super hard construction has a body of PCD material and a plurality of interstitial regions between inter-bonded diamond grains forming the PCD material. The body also has a first region substantially free of a solvent/catalyzing material which extends a depth from a working surface into the body of PCD material. A second region remote from the working surface includes solvent/catalyzing material in a plurality of the interstitial regions. A chamfer extends between the working surface and a peripheral side surface of the body of PCD material. The chamfer has a height which is the length along a plane perpendicular to the plane along which the working surface extends between the point of intersection of the chamfer with the working surface and the point of intersection of the chamfer and the peripheral side surface of the body of PCD material. The depth of the first region is greater than the height of the chamfer. A first length along a plane extending from the point of intersection of the chamfer and the peripheral side edge of the PCD body at an angle of between around 65 to 75 degrees to the interface between the first and second regions is between around 60% to around 300% of the depth of the first region.
