Dendritic opals exhibit distinctive visible traits stemming from manganese or iron oxide inclusions forming branching patterns resembling ferns, timber, or moss. These inclusions, technically not dendrites within the crystallographic sense, are embedded inside a translucent to opaque opal matrix, usually widespread opal or hyalite. The charming visible impact arises from the distinction between the darkish inclusions and the lighter opal background, creating scenic landscapes throughout the stone.
This distinctive look has made these gems prized possessions for hundreds of years, employed in jewellery and ornamental objects. Traditionally, numerous cultures attributed symbolic meanings to the dendritic patterns, connecting them to nature, progress, and abundance. The relative abundance of dendritic opal and its affordability in comparison with treasured opal varieties have broadened its enchantment, making it accessible to a wider viewers. Its sturdiness, mixed with the mesmerizing visible enchantment, ensures its continued recognition amongst lapidaries and collectors alike.
