Emerald jewelry
would be the classic gift for the 55th anniverary, but feel free to try the modern material of turquoise jewelry as a lovely alternative.
Gifts for the couple might include a dark green or light blue decorative item for the home. Perhaps an emerald green artisan glass bowl or a Swarovski green crystal figurine.
For an exotic gift, send the happy couple
to Ireland, the Emerald Isle, or Emerald Bay in the Cayman Islands.
