The hallmark stamped into an 18kt white gold piece is small and specific. '18K,' '750,' or '18ct' depending on where the piece was made, each mark a confirmation of the same standard: 750 parts per thousand fine gold by weight.
Stone Story
Gem-quality mined diamonds are extracted primarily from kimberlite pipes, which are ancient volcanic formations. Each pipe's specific geological chemistry produces diamonds with characteristic inclusion types, crystal morphology, and trace element profiles that can indicate a stone's origin region.
Elemental Detail
18kt white gold carries a higher proportion of pure gold and may read slightly warmer in tone than 14kt; 14kt white gold's higher alloy content delivers greater hardness and scratch resistance, making it the more practical choice for pieces subject to daily contact.
