Pourquoi cette pierre est-elle si spéciale ?

Il existe de nombreuses variétés d'obsidienne. Celle-ci combine la variété acajou et la variété argentée, ce qui en fait une pierre tout à fait spéciale. Le nom d'Acajou vient de sa couleur fauve faisant penser au bois d'Acajou.

Called Mahogany Obsidian because the red is similar to mahogany wood.

This deep black Obsidian with blood red streaks is found in central Oregon. 

These beautiful designer cabochons also have a chatoyant gold sheen effect. When rotated in bright light there is a golden flash of color!

This semi precious gemstone material is translucent and some of it actually looks banded or striped when lit with a back light.

Black Obsidian is a natural volcanic glass. This glassy, lustrous gemstone is found in lava flows. Obsidian is produced when lava cools very quickly. The lava cools so quickly that no crystals can form. The red coloration in Mahogany Obsidian is likely the result of trapped hematite.

Obsidian was named after a Roman- Obsius, who is said to have discovered it.

Mahognay Obsidian cabochons have a hardness of 5 to 5.5.


Metaphysical Properties Of Obsidian:

Mahogany Obsidian is said to be a very grounding stone, and very healing. It is said to dispel feelings of unworthiness, that can hold one back from achieving their full potential. It sharpens and focuses internal and external vision, and helps one get in touch with buried issues before they can explode.
