A very rare variety of Ruby with inclusions forming a star-shaped pattern.
First described 1991
Origin of name: Trapiche is the Spanish word for the cogwheel used to crush sugarcane. In this very rare type of Ruby inclusions form a pattern resembling the spokes of a wheel.
Can be confused with: no other gem
Localities: at the time of writing (July 2018) only there are only two known sources. One is in Mong Hsu, Myanmar (Burma), the other in the border area between the two Indian federal states of Karnataka and Andhra Pradesh.
Burmese Trapiche Rubies hardly ever reach a weight of 1ct.
From India specimens of more than 70cts are known.
Worth knowing: Indian Trapiche Rubies are currently (2018) mined in two pits. One yields red to dark red specimens, while gems from the other pit are characterized by a distinct purple hue.
The Indian occurrences were discovered somewhat accidentally, while (unsuccessfully) prospecting for uranium ore.

Brought this to lab for certification. It is a blue spinel, but cobalt content insufficient to be classified as cobalt spinel. Would not have paid as much for it had I known. Though it is still a nice stone so giving positive rating.

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.
