Cultured pearls are composed of nacre, the same organic gemstone material as natural pearls. The fine jewelry industry's classification of them as precious gemstones reflects that material reality.
Care & Keeping
A 14kt white gold piece won't tarnish, but it's worth knowing that the rhodium plating providing the bright white finish will wear over time with regular use. When it does, a jeweler can re-plate the piece and restore the original appearance.
Built For Ease
Clutch backs are sized, which matters more than it sounds. Standard fine jewelry posts accept a range of clutch back sizes, but heavier earring formats need the weight distribution that larger comfort-back options provide. The back is calibrated to the post gauge and the earring's weight, and getting that calibration right affects both security and comfort.
