Sphalerite is a zinc ore mineral that typically contains iron. When it has a high iron content, sphalerite is an opaque black. Gem-quality material has a low iron content, resulting in transparent crystals. Due to its lack of hardness, it is mainly a collector's gemstone. One of the most notable characteristics of sphalerite is its high dispersion (0.156). In fact, the dispersion of sphalerite is over three times that of diamond, which has a dispersion of 0.044. This means that sphalerite has remarkable "fire"; the separation of visible light into colors by refraction or diffraction. In simple terms, this refers to the flashes of color seen when sphalerite is turned in the light.
Due to its composition, sphalerite is also known as "zinc blende". The name "sphalerite" comes from the Greek word, "sphaleros", which means "deceptive". This is because sphalerite is easily mistaken for galena, which is the mineral form of lead sulphide. Gem quality transparent sphalerite is rare. Sphalerite is typically yellow, orange or red. A black, iron rich variety of sphalerite is called marmatite.

Waarom overbieden gebruikers zichzelf?
Wanneer er wordt geboden, is dit het maximale bedrag dat een gebruiker bereid is te bieden op het product. Ons systeem zal dan automatisch namens die gebruiker bieden, waarbij het bod stapsgewijs wordt verhoogd om hun positie als hoogste bieder te behouden, tot aan het opgegeven maximum.
Als er een pictogram is dat 'Automatisch bieden' aangeeft, betekent dit dat ons systeem actief biedingen plaatst voor de gebruiker op basis van hun maximumbod. Dit kan lijken alsof gebruikers zichzelf overbieden, maar het is gewoon het gevolg van het feit dat het systeem het bod bijwerkt om de maximumlimiet van de gebruiker weer te geven.
