Caring For Diamonds

While diamond's are considered the hardest substance in the world, they do require additional care to preserve their faceting and overall sparkle. Four Mine offers complimentary lifetime cleaning to restore your jewelry to it's original shine.


Cleaning Loose Diamonds

  • Polish clothes are a great way to remove excess oils that stick to diamond surfaces. They cleanly wipe away common skin oils that dull a diamond's sparkle.
  • Mild soap and warm water are highly effective at cleaning away dirt and grime that sticks to the loose diamond's surface. Use a gentle toothbrush to shake loose dirt in set jewelry.
