An exceptionally large, finest rough emerald crystal from Muzo. This was offered at $45,000 wholesale price in Bogota’ in 2004. It cut two stone (match pair) of squares 7 cts. each.
Viewing an emerald rough with loupe on the famous Catorce or emerald market in Bogota.
Many of the brokers are women. My best stone during that trip, an exceptionally clean Muzo stone, heart shape of 5.65 ct. was purchased from a beautiful, female broker…nothing new about this selling tactic…except that it works well for the seller.
Checking emeralds. To know emeralds quality and price takes a lot, lot of experience. Checking emeralds under special loupe. A careful, close-up examination is very important. There are many synthetics offered to foreign buyers.
A fine parcel of emerald crystals is examined. Technician checking more emeralds at a typical office. A master cutter, initializing the cutting process of an exceptional emerald crystal. This process is thought through very carefully before the cutting begins.
The master cutter’s wheel and examining the emerald crystal and try to decide how to get rid of the included section (whitish portion in the emerald crystal). Probably that occurred when the crystal was broken away from the rock host (matrix).
Here is the final result: Finest color, top clarity and awesome cutting for this finest match pair, 8.5 cttw. from the Muzo crystal seen previously. In Colombia, top emeralds are called “gota de aceite”, that means “oil drop”. Were offered for sale in November 2004 in Bogota for several thousands of USD per carat.
