If the Dragonborn steals anything from her, she may send Hired Thugs to teach him/her a lesson. She gives the quest 'Deliver the ring to Calcelmo'.
The Dragonborn can overhear a conversation between her and Hroki stating that she sells a special jewelry worn by nobles in Hammerfell.
In the thieves guild, a side quest "The Fishing Job" requires to pickpocket a particular diamond referred to as "Kerah's Diamond" from her. It is recommended to have a slightly higher pickpocketing skill as the main places for trying to pickpocket her is out in the middle of the market with people watching (during the day) and in her house while she sleeps (during the night). The only problem at night is that her child is always in the very front of the inside of the house and she may easily catch the Dragonborn if the house is broken into (Using the Illusion spell Calm can temporarily silence her child--except for the "Wow...that was fun! Do it again!" line that Illusion spells cause most children to utter).
