Rose 'Rosie' Quartz is a secondary character in the Muffins series. She is the grandmother of main characters Minkie, Inkie, Blinkie and Pinkie Pie.

Backstory
Rosie got her cutie mark when she discovered she enjoyed making jewelry out of the rocks on the rock farm she grew up on.

She grew up in a religious household, and was frowned upon by her community. She was incredibly happy, carefree, and she enjoyed the small things, which wasn't proper behavior. As such, she was often accused of being a harlot.

In hopes that she could be grounded and calmed down, her parents arranged a marriage with a stallion named Mudstone (whom she called Muddy, much to his dismay), who was part of a well-known, religious family. This didn't work, as Rosie was always trying to get Mudstone to smile and loosen up, despite his efforts to get her to behave. They eventually had 3 children together; two daughters, Cloudy Quartz and Amethyst, as well as a son named Garnet. Rosie would call Amethyst 'Ammy' and Garnet 'Garnie', which they hated.

It got to the point where Mudstone got so fed up with Rosie's behavior that he filed for divorce through the church. Due to Rosie's personality, Mudstone was granted majority custody of their children, and Rosie was only allowed to see them on the weekend. Their three children didn't follow Rosie's ways as they grew up on their father's rock farm, falling into a monotone, reserved life of no laughter or fun. They grew to hate their mother's visits, especially Cloudy.

After their children got married and moved to different rock farms, Mudstone died due to a stress induced aneurism, which in Rosie's opinion was due to his dull personality. Occasionally, Rosie would visit their children, and she visited Cloudy when she was pregnant with her first daughter Minkie. The next time Rosie visited, Cloudy insisted she had miscarried and didn't want to talk about it ever again.

Rosie visited again when Cloudy's 3rd and 4th daughters Blinkie and Pinkie were born; she was ecstatic to see the latter was pink and knew great things would come from her. After Pinkie's birth, she visited more often and teach her grandchildren things such as happiness, and how to reduce negative emotions.

Rosie's next visit came after Pinkie had left to travel to Ponyville.
