A seed crystal holder for growing single crystals, such as for use in scintillation detectors for nuclear medicine. The holder includes a cooling shaft, a fastener attached to the cooling shaft, and a gasket for separating the cooling shaft from the seed crystal. The gasket is made of a heat-transferable material such as steel wool or metallic foil to conduct heat from the seed crystal to the cooling shaft, while also providing a cushioning effect to cushion the seed crystal against potentially damaging motion forces.
