I know, but still insist that the things that separate this unique item are themselves small or large.
If an item separates itself from the others on mutliple dimensions, then it is more unique than an item that differs only in one dimension.
Both of them are the only things like themselves. I have a collection of vases. Almost all of them are roughly the same size (15cm), shape (round; tapered), and color (clear or white). But there are two that are different: "A" is green instead of white, with a square base.
B is made from petrified buffalo dung, stands 1 meter tall, must be carefully balanced because it's so heavy on top (and skinny at the base), and is covered in velvet.
All snowflakes are unique. Would a red snowflake be more unique? You might personally find the color axis more interesting, but it's just one of a huge number of axes along which the snowflakes are different. The red one is more interesting to you but it isn't actually "more unique". The same is true for your vases.

A is unique. B is definitely more unique.
