18k gold is 75% pure gold, alloyed with other metals for strength and durability. Compared to 14k (58% gold), it has a richer, warmer color and a more luxurious feel. It won't tarnish, fade, or wear away over time.

We chose 18k because we want every piece to look and feel as beautiful in 20 years as it does the day you bring it home.

All Mac Knowles pieces use natural diamonds, ethically sourced through the Kimberley Process. We believe natural diamonds carry a one-of-a-kind character that aligns with our philosophy of creating jewelry meant to be treasured and passed down.

18k gold will not tarnish. It can develop minor surface scratches with daily wear over time. This is normal and gives fine gold jewelry its distinctive lived-in character. If you ever want your piece cleaned, polished, or refreshed, contact us at team@macknowles.co to coordinate.
