Clara is average height for a female, however she is slightly taller. She has a blonde choppy bob hairstyle ending at her chin, blue eyes, and dark brown thin eyebrows. She has a small, distinct brown birth mark on her right leg just above her ankle. Outside of school uniform, Clara tends to wear clothing that consist of colours such as blues, purples, whites, blacks, and grays. Most of these clothings are dresses and skirts with the casual jeans, t-shirts, jumpers, boots and converse shoes; inspired by her Muggle heritage.

Clara's father is a Half-blood while her mother is a Muggle. Clara is also born with a twin brother, Andorus Goldstone, who does not possess the ability to perform magic and will forever live a Muggle life. As much as Clara wants to maintain a bond with her brother, her time in the Wizarding world continues to drift them apart due to her brother's jealousy. This has caused a slight conflict with her family, but due to her father supporting Clara's path to attend Hogwarts, their relationship continues to grow. Being Australian, her family has compensated her trip to London, her father travelling with her to stay with their wizard family, consisting of: Clara's grandparents, Aunt (her father's sister) and many cousins. This decision was highly encouraged due to the family's history of attending Hogwarts. Nonetheless, she has grown with a loving family, and one she will never abandon.

Clara is a quiet, curious girl who seeks and thrives for an adventurous lifestyle, but when she starts talking or an idea sprouts in her mind, she will not hesitate to gather attention. She tries to be as friendly as she can be, especially when meeting someone new, and she believes that it's important to always keep a positive attitude and outlook of life. However, she may be somewhat naive for her constant positivity, and her curiosity sometimes leads her into trouble. Due to her caring nature, she wishes to learn more about the magical creatures of the Wizarding world, perhaps considering a career as a Magizoologist. However, despite how fragile and sweet she looks and acts, the creatures that interest her most are dragons. Ever since she learned about such magical beasts when she was 7, told by her father in the form of a story, she has grown ever so curious about these beasts. She believes that there could be more that wizards and witches could learn about dragons, and how misunderstood they could be. Her father is a little worried as he believes that becoming a Dragonologist will be very dangerous for Clara, but she persists to hold true to her passion.

When she was 4, her magical abilities started to show form as whenever Clara showed great emotion such as laughter, small objects around her would begin to float, and whenever she was crying, fragile objects such as plates and glasses that are in her vicinity will find their way to fall off shelves and break, issuing her parents to keep her from crying as much as possible. Now, attending Hogwarts, Clara loves to work hard for something she enjoys doing; alongside drawing, writing, and listening to music. She doesn't look the part, but Clara enjoys listening to heavy metal music! Muggle music, one would say, but Clara feels no shame to embrace both her Muggle and Magical heritage.
