Elbaite, chemically is Na(Li1.5Al1.5)Al6Si6O18(BO3)3(OH)3OH, a very chemically complex mineral containing sodium, lithium, aluminum, silicon, boron, oxygen and hydrogen. It is a member of the tourmaline group. The name tourmaline comes from the Sinhalese word “Thuramali,” meaning colored stone. The pronunciation of the word changed to tourmaline by the linguistic mangling of European traders from the Dutch East India company that imported stones of multicolored tourmaline, likely mostly elbaite and dravite from Sri Lanka in the 17th and 18th centuries. The tourmaline group minerals, including elbaite are fondly known as the “garbage pail minerals” by geologists because they act as a sink for many incompatible lithophile elements (lithium, boron, fluorine) that cannot fit in the crystal structures of most rock forming minerals. Tourmaline, especially elbaite isn’t garbage at all in the eyes of gemologists, jewelrymakers, and mineral collectors who value the mineral for its diverse, vivid coloration, high luster, and hardness. Elbaite can be faceted into beautiful gemstones or wirewrapped- both are appropriate for the mineral considering its high hardness of 7 1/2 on Moh’s hardness scale.

Elbaite crystals are colorless if completely chemically pure, but are usually brightly colored. Iron impurities color elbaite green and blue while manganese impurities color elbaite pink and red. Pink and red elbaite crystals showing high color saturation usually have been exposed to elevated levels of natural geological radiation when they are forming deep in the earth. This radiation is caused by decay of potassium-40 and oxidizes the manganese from Mn(II) to Mn(III) which increases the color saturation. This exposure to radiation does not make the crystals dangerous in any way. Elbaite can be artificially treated or enhanced after collecting. The most common treatment is irradiation, which deepens the color similar to how it happens naturally. Irradiation in elbaite stones is usually impossible to detect. elbaite can also be heat treated to enhance color. Clarity enhancement of rarer elbaite such as Paraiba tourmaline seriously detracts their value.

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.
