What Is Dendritic Agate Sphere Worth?

The typical price range for Dendritic Agate Sphere is $35 - $38 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The complexity and clarity of the dendritic patterns significantly impact the $35-$38 price range.
• The quality of the sphere's surface polish and the absence of surface-reaching fractures or pits.
• The overall translucency of the host chalcedony, which provides better contrast for the dark mineral inclusions.

How to Identify Dendritic Agate Sphere?

• Look for dark, branching arborescent inclusions that resemble ferns or trees within the translucent chalcedony.
• Verify the smooth, high-gloss polish characteristic of modern Brazilian lapidary work from the 2010-2024 era.
• Check for the natural variations in the white to gray chalcedony base, which should not show artificial dye lines.
