Dragon Veins Agate meaning: Dragon Veins Agate is also known as Fire Agate and Crab Fire Agate. It is not the same as Mexican Fire Agate and is oftentimes the product of a dye process and a crackling process which produces the veins. It is gorgeous and the processing seems to have a positive affect. In other words, Dragon Veins Agate metaphysical properties can be quite healing. All I can think is that the intention behind the processing is to make the agate more valuable and so that is the manifestation as well.
