The rare feature of a six lined star fixed within the mineral structure of a gem stone was first discovered in emeralds in Colombia at the end of the 19th century. As this pattern was resembling the wheel of a sugar cane mill, the Spanish word for it “trapiche” became the synonym for these emeralds and later for any gem with a similar growth pattern.
100 years later at the end of the 20th century this phenomenon was first described in corundum crystals. Rare small pieces of trapiche ruby and sapphire were found mostly in Burma and became a sought-after collector’s item.
Now trapiche rubies were discovered for the first time in commercial quantities and in different qualities and sizes at a mine in South India. The crystals were growing in a hexagonal form and some can be very big with a weight of over 1500 ct. They are polished and manufactured by our partners in the Indian gemstone capital Jaipur in Rajasthan .
