Random Pull Tumbler Sized Swazi Agate Rough! Photos taken wet to simulate a polish and show their true color. Swazi Agate is a form of agate found in Mozambique, Africa. It also goes by the name of Swali Agate or Mozambique Agate. The main colors of Swazi Agate are often Carnelian, Pink, or Blue, but it can also have nearly every other color in the spectrum. It takes an excellent polish, and is a fan favorite for tumbling. It can be a great beginner tumbler. We personally recommend at least 2 rounds (weeks) of 80 grit to get rid of the skin, and then proceed with your normal formula for polishing agate via rotary tumble or vibratory tumble.
