14k gold, at 58.5% pure gold, carries a deeper, richer warmth and is the traditional standard for fine jewelry intended to be worn close to the skin for a lifetime. 10k gold, at 41.7% pure gold, is the more resilient choice for everyday chain necklaces that move constantly throughout the day. Both are solid gold, both are handcrafted in our Athens workshop, and both are built to outlast anything mass-produced.
