Calamansi or Kalamansi which is the actual spelling in tagolog (Filipino language) is a fruit grown all over Southeast Asia and it is very popular in the Philippines where it can be found in abundance and is known as the "golden lime". 
  
It holds a citrusy and tangy smell...Let's a lemony/limey combo with an amazing blossom flower scent.  It's a very pleasing scent to burn all over the house.
