The gem measures 7.62 mm diagonally across from one edge of the girdle to the other edge.
If a diamond, the gem weighs between 1.50 and 1.75 carats.
A 2 mm round diamond weighs about .03 carats, so a 1.5 mm round diamond would be smaller than .03 carats. A .01 carat diamond is about as big as a grain of sand.
If the measurement you give -- 055 -- is converted to .55 carat, and the diamond is a round brilliant cut diamond, the diameter of the diamond at the girdle is between 5.2 MM and 5.6 MM, being the MM measurements of .50 and .60, respectively.
Depending on the depth of the round brilliant cut, the measurement can be estimated at about 8 mm at the girdle.
A 20 carat diamond weighs 20 carats. If the diamond is a round brilliant cut, it measures about 17.6 mm at the girdle.
The millimeter size of a diamond of this weight varies, depending on the cut. If the gem is round cut, its measurement at the girdle will be between 16.3 mm (15 carats) and 17.6 mm (20 carats).
