This patent describes a diamond-anvil high-pressure cell having a tubular piston and a cylinder in which the piston is slidable to effect compression of a pair of opposed diamonds located between the piston and the cylinder. The piston includes a central bore opening on one end, an adjustable X-ray collimation system comprising a tubular insert engageable in the bore of the piston, the insert including a central bore and having first and second ends, with the first end of the insert being closest to the opposed diamonds and the second end of the insert extending out of the open end of the piston, a collimator insertable in the bore of the tubular insert. The collimator has a central bore and having first and second ends corresponding respectively with the first and second ends of the insert, elastomeric pivot means mounted in the bore of the insert at the first end of the insert for flexibly retaining the first end of the collimator while allowing the collimator to pivot within the pivot means, and adjustable locking means located at the second end of the insert for adjusting and securing the second end of the collimator so as to be in alignment with the opposed diamonds.
