What does platinum 0.2ct E VS1 emerald diamond mean?

It's possible to interpret the codes as:

• Platinum = name of the metal
• 0.2 = 2/100s of a carat, or two points: its weight
• E = the colour, D being the highest jewelry grade
• VS1 = there is one Very Slight flaw (type not specified)
• Emerald = name of the cut

Actually, it would make more sense that this stone be a 2.0 carat stone instead of a 0.2 carat stone. Everything else about its description points to this being a larger stone.
