Tanzanian bicolor tanzanite rough stone 2.454ct
The appeal of tanzanite is its "pleochroism," which means that it appears in different colors when viewed from different angles. It's never boring to watch the various blue colors, such as blue, blue-purple, and ultramarine, dancing within the stone. This is a bicolor tanzanite, in which multiple base colors can be seen. It's luxurious to have bicolor and pleochroism. Please roll the real thing and take a look at it. This is a 2.454ct rough bicolor tanzanite from Tanzania with high transparency.
