Pink sapphire diamond hearts, a cherry blossom flower piece, amethyst and garnet hearts in 14k — women's gemstone necklaces run color-first here: one hundred seventy–one pieces where the stone shape does as much talking as the stone.
The heart is this case's native shape — soft cut, safe to wear daily, and January and February birthdays get garnet and amethyst versions that double as birthstone gifts. Pick depth of color over size at the neck; a smaller vivid stone beats a bigger pale one whenever light hits. The matching drops for shorter chains sit at women's gemstone pendants.
