Jewelry designer Caroline Ellen, 46, crafts delicate pieces from lush yellow gold that feel modern when layered. Her collection, Caroline Ellen, includes many of the staples she wears herself, such as a chain with black diamond beads ($2,650), plain and engraved rings (from $1,400 each), diamond eternity bands (from $2,650 each), and a faceted oval ruby ring (on index finger, $2,050) that's striking in its restraint. "The Earth is a treasure box of all these beautiful stones," says Ellen. "I don't want to detract from them with complicated settings." Her everyday accessory, a heart-shaped pendant engraved with her two children's initials, is especially cherished—and among her favorite styles to personalize for others (chain, $2,420; pendants, from $1,450 each). "This kind of sentimental jewelry is so much a part of me that I feel naked without it," she says.
