QUALITY ROUGH

LAVA PALINS ROUGH SAPPHIRE
This is a natural untreated sapphire specimen from the lava plains in queensland.There are inclusions is this piece so it will cut only a smaller stone or it can be kept as a specimen from this field or skin polished.This field for its quality natural blue stones.

The smaller Lava Plains field differs markedly from the Anakie field in that the basalts that host the sapphires are very much in evidence on the field. Located 100km south of Mount Garnet and mining is centred on the Wyandotte Creek area.

r between 70 and 40 million years ago some volcanic activity erupted across the area spewing out basaltic ash and lavas. All that remains of these volcanoes now are plugs of lava that once filled their vents (eg Mount Hoy, Mount Leura); the rest having been eroded away. Referred to as the Hoy Basalt Province, it is one of many similar volcanic suites that are found throughout the highlands of eastern Australia.
It is believed that during the first phase of volcanic activity, abundant sapphires, spinels, garnets and zircons were blasted from the volcanoes as crystals in volcanic ash. Later less violent eruptions brought more normal basalt lava to the surface, carrying only a few sapphires as have been noted in the basalt at Mount Leura.

The sapphires have since been released from the volcanic material by weathering and erosion, transported by old streams, and concentrated in various layers of gravel (known as “wash”) of Pliocene to Pleistocene age (2 million to 10 000 years ago). This “wash” has also been cut into by present drainage systems.

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.
