Zusammenfassung:	A method and apparatus for hydrothermally growing crystals in a pressure vessel (10) containing feed crystals (24) immersed in a mineralizing solution. The apparatus is disposed in the pressure vessel, above the mineralizing solution. The apparatus includes an enclosure having opposing major walls with passages extending therethrough. The enclosure completely surrounds a seed plate (33) having opposing major faces. A restraining structure holds the seed plate within the enclosure such that the major faces of the seed plate are spaced inwardly from the major walls.
