What is the significance of Garnet's name in the novel, Thimble Summer?

Garnet's symbolic name refers to both a dark red color and a gemstone. Jewels and jewelry figure often in the images of Thimble Summer. For instance, in her story of youth, Mrs. Eberhardt tells of her desire to own a particular coral bracelet with a coral heart hanging from it. Coral as a color is red, recalling Garnet's name; the heart is like a gem, again recalling Garnet. This symbolism helps to convey the idea that Mrs. Eberhardt's story of the past is related to the Garnet of the present. The overall impression created by Garnet's name is that she, herself, is a jewel—as bright and colorful and precious as a gem.
