Buy Brazilian Opal
from opal miners direct. This opal has a good reputation and has tended to be white semi-transparent to see-through body tone. It is considered very stable as there is less water content than other opals.
Also known as Brazilin crystal opal or Brazilian Pedro Segundo opal, it can display beautiful veins of color and come in freeform shapes that have thick color bars. These are ideal for carving. Some colors are magical patterns called ‘rainbow’ and patterns display skin to skin which refers to color within the whole Opal. This is another reason freeform shapes are popular with jewelers to create a unique jewelry design as not many opal fields have color on both sides.
