Chondrodite

The specimen features a well-defined crystal with a honey-brown to dark brown coloration, showing lighter tones along the edges. The luster ranges from resinous to vitreous, especially noticeable on fresh surfaces and conchoidal fractures.

The crystal displays a compact habit with rounded, somewhat irregular outlines, typical of metamorphic growth in magnesium-rich environments. Slight translucency is visible along thinner edges, revealing warm amber internal tones.

It is set within a light-colored matrix, likely calcitic or dolomitic, consistent with skarn or metamorphosed magnesium-rich marble settings.

Chondrodite belongs to the humite group and is a magnesium fluorine-bearing silicate, typically forming in contact or regional metamorphic environments affecting carbonate rocks.

Shipping to the USA : 

Recently all my padded letters came all back to me, in fact, they are normally only for "gifts" so they are not going through customs anymore (and warned me of a fee ..).

From now on, all shipping to the US will be made in packages, only way to send to your country.

I can offer to wait before to ship if needed
