Here are earrings of carved carnelian flowers with diamonds and seed pears set in yellow gold. Carnelian falls under the chalcedony (kăl-sĕd'n-ē) species which is related to quartz. Varieties of chalcedony are usually differentiated by color; multi-color banded chalcedony are usually labeled as agate, black and white banded ones are called onyx and orange ones are called carnelian. And here are some exceptional ones with vivid color, waxy texture and translucency.
