NATURAL DENDRITIC QUARTZ

BEAUTIFULTREEPATTERN

TREATMENT - NONE

Dendritic Quartz with it’s tree like, fern shapes and branches is a very interesting and pleasing gemstone. . Although the dendritic pattern appears as a fossilized plant, it is really inorganic manganese oxide. When moisture and iron mix, the result is oxidation, better known as rust. Oxidation is an every day occurrence. It even happened in gemstones. Traces of moisture and iron or manganese were trapped inside quartz, which produced stains resembling trees or branchescalled dendrites. The word Dendrite comes from the Greek word “dendron” meaning tree. Hence the name Dendritic or Dendrite Quartz. The stains are found in microscopic fissures that cause them to branch out like tree limbs or fern like inclusions. Of course in nature no two things are alike, making each gem one of a kind . Quartz can have inclusions of other minerals also, including, chrysocolla, azurite, malachite, chlorite or goethite. These inclusions have the ability to tint their host red, orange, yellow, green, blue and black. Dendrites can occur in other gems as well, including opal and beryl.

Dendrites are most often formed by manganese oxide or manganese oxides. Some of the other manganese oxides that form dendrites, are in the hollandite group of manganese oxides. They are coronadite, cryptomelene and hollandite. Two other manganese oxide minerals that form dendrites are romanechite and todorokite.

Like most included quartz, the primary sources of Dendritic Quartz are Brazil and Africa.

Why are users outbidding themselves?

When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.

When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.

Audit

The Gemstone Sheriff program allows our members to request an audit on any product, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
