The name "Blue Lace Agate" comes from the alternating bands of pale blue and white that resemble delicate lace fabric. Similar to regular agates, these bands are formed over millions of years by layers of slowly flowing lava that eventually settle on top of one another. Even though it takes a while, the result is definitely worth the wait for this special gemstone. While most commonly found in South Africa, Blue Lace Agate has also been found in China, Brazil, India, and some areas of the United States. The stone's name comes from the way that thin white and pale blue bands are intricately combined to resemble exquisite lacework.
