What Is Tourmaline Crystals Worth?

The typical price range for Tourmaline Crystals is $150 - $180 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

How to Identify Tourmaline Crystals?

• Observe the vertical striations running parallel to the length of the crystal, which is a hallmark of authentic tourmaline.
• Examine the crystals for pleochroism, where the color intensity or hue changes when viewed from different angles.

• Verify the origin as Pakistan, a region known for producing high-quality specimens with distinct clarity and color zoning.
