Mountains, trees, seas, and flowers display Earth's diverse color spectrum, while deep beneath the soil, nature's purest hues are also perfectly preserved — in gemstones.

A sapphire ring is one such example, its clear hue in harmony with the glare of the flanking diamonds, capturing the eyes and hearts of those who will bid at China Guardian (HK) Auctions' upcoming sale in October.

The auction items feature a variety of jewelry, accessories and collectible handbags that infuse Earth's finest products with human creativity and craftsmanship, blending Eastern and Western aesthetics.
