The gemstones that go extremely well with a white gold necklace often have bright colors that create a striking contrast with the white metal. White gold provides a neutral and sophisticated backdrop that complements various gemstones. Popular choices include diamonds, sapphires, emeralds, rubies, and aquamarines. Diamonds, with their brilliant radiance, are a classic and timeless choice, while colored gemstones such as sapphires and emeralds are vibrant in hues.
