Black Ruthenium Finish Care
  • Please note that our black bands are crafted in solid 18K White Gold with a black ruthenium finish.
  • The black ruthenium plating may wear off over time.
  • The longevity of the finish depends on your body chemistry, how you care for your jewelry, and your usage habits.
Black Diamond Information
  • Most black diamond jewelry available today is crafted using natural diamonds that have been permanently color enhanced to achieve their distinctive black appearance.
  • This treatment is stable, permanent, and widely used throughout the fine jewelry industry.
Sizing & Scale Note
  • Please note that because this is a full eternity design, the exact stone count and total diamond carat weight will vary depending on the ring size you select.
