A method of making clear ice spheres includes a providing a mold apparatus having a first mold portion and a second mold portion having mold cavity segments which define one or more mold cavities when the mold apparatus is assembled. A clear ice sheet is deposited in the mold apparatus in a channel defined by the spaced apart mold portions when the mold apparatus is in an open position. The mold apparatus is assembled about the sheet of clear ice such that the clear ice sheet is shaped to form one or more clear ice structures in the mold cavities.
