Abstract

PURPOSE: Title single crystal having very close resemblance to an original natural gem stone in color, transparency, etc., prepared by taking a colorless, transparent garnet structure composition as a base, and replacing the Y lattice with a rare earth element having an ionic radius which is nearly equal to that of Y.
CONSTITUTION: A single crystal of a colored garnet for ornaments, having a composition represented by the general formula, wherein M is a rare earth element, and 0≤X<3. A single crystal having a desired color (cf. Table) is obtained by crystallizing and growing a mixture prepared by selecting a rare earth element with which Y or Y3Ga5O12 is replaced and mixing each oxide so as to provide a predetermined composition, in a usual manner such as Czochralski method. The use of Cr, Co, Ti or the like, in addition, as an accessory component makes it possible to produce a single crystal with a delicately controlled color.
