A pair of earrings that don't match

I am making a pair of earrings. They go together as a pair but they do not match each other. What word explains this?

Solution 1:

asymmetrical

From the South China Morning Post, see an article titled 6 asymmetrical jewellery pieces that add edge to classic luxury.

Chanel, Chaumet, Graff, De Grisogono, Harry Winston and Van Cleef & Arpels offer asymmetrical and artistic pieces.

Scroll down to De Grisogono and then to Harry Winston to see two pairs of earrings. Each pair is obviously a pair, but in the De Grisogono pair the role of the diamonds and rubies are reversed, hence the pair is asymmetrical. In the Harry Winston pair, the front and back of each earring can be reversed, so that the lucky owner can wear them as a matching pair or an asymmetrical pair. (Diamonds, sapphires and aquamarines.) The prices are not given: if you have to ask, you can't afford them.

Although the South China Morning Post might seem a strange arbiter of English, in this price range (6 figures and up), fashion writers get it right.

Solution 2:

Perhaps the word "mismatched" would fit this situation.

Solution 3:

A further option is mix and match (dictionary.com):

(adj) made up of complementary elements taken from different sets or sources

The phrase can also be used as a verb.

It's used in exactly your context: Mix and match earrings: why you should try this jewellery trend (Woman and Home) for example; many shops selling them singly (to allow you to mix and match your own pair) use this term as well.
