るところにある。However, although black star sapphire is promising as a jewelry component, the synthesis technology for it has not been established to date. The present invention is intended to solve these problems, and its purpose is to provide a synthesis technique for black star sapphire as a jewelry member.

成させた。Table 1 shows the composition of the raw materials used in the present invention. First, the composition was weighed so as to have the composition shown in Table 1, and then thoroughly mixed with distilled water and dried at 200℃ for 1 hour.
The pieces were packed to a length of about 100 intestines, and pressed and molded using a hydrostatic pressure generator at a pressure of 1 ton/cJ for about 5 minutes. The round rod-shaped samples thus obtained were sintered in an electric furnace at 1600° C. for 4 hours to obtain three types of sintered raw material rods. Set each of these sintered raw material rods on the upper side of the condensing YZ furnace, and set the Bernoulbee lower (11i1) as a seed crystal. Gradually increase the power of the halogen lamp until the tip of the raw material rod seed crystal partner melts. Then At the point where the tip of the partner is melted, the raw material rod is gently lowered and the partner is fused.At the fused place, the raw material rod and the seed crystal are held in that state for 1 hour to blend well, and after 1 hour, 2 W The crystals were grown at a speed of /H.

Because the amount added was too large, segregation occurred in the center of the crystal, resulting in cracks.

実施例２については色も良くスター効果も大変鮮明であ
った。In Example 2, the color was good and the star effect was very clear.
