Locations

 * 1-8: They are In The Bowery.
 * 9-16: They are In Park Row.

Protocol 10
Catwoman, right before Protocol 10, decided to break into the vault of Hugo Strange. She stopped when she learned Batman was going to die and consequently Two-Face was then able to steal them.

Two-Face
Catwoman gets revenge on Two-Face by getting half the jewels back. She learns half are out in Arkham City.

After Arkham City Incident
Catwoman proceeded to acquire her items.

Trivia

 * Oddly, Two-Face says he gave her stuff away, but it was just guarded by his Men.
