The nine largest pieces of the Cullinan Diamond.
The Cullinan IV (upper, 63.60 carats) and Cullinan III (lower, 94.40 carats), set in a pendant brooch.
The Cullinan VI (lower, 8.80 carats) and Cullinan VIII (upper, 6.80 carats)
The Cullinan II Diamond. Note the two tiny platinum loops on the edges. This is so the stone can be worn as a brooch, alone or with the Cullinan I attached. However, it usually resides in the front of the Imperial State Crown.
Titanium is used in automobile body parts, manufacture of aircraft, eyeglass frames, and sport equipments such as tennis rackets and bicycles, and wheelchairs used by people who want to race or play basketball.
