Sapphire (''Trapiche'') (ex Bill Larson Collection)

Item Description

Here we have a wonderful Trapiche Sapphire from Myanmar, where arguably the best examples of this material are found. For reference, the term "Trapiche" derives from the name of a Spanish mill consisting of wooden spokes or rollers that were designed to extract the juice from fruit, including olives, dating back to the Middle Ages. The term has been used since 1879 when Emile Bertrand used it to describe Emeralds from Colombia. The dark six-sided star shaped patterns seen inside the crystals (when viewed looking down the "c" axis) are similar to the actual spokes of a trapiche machine. These rays appear much like asterism, the only difference being that they are fixed and do not move. A Trapiche is the result of the hexagonal shape of the crystal, where the darker impurities interrupt the growth of the crystal and are pushed to the center of the crystal and then radiates out in the six directions of the corners of the crystal. Here we have a rather large "Oval Cabochon" cut Trapiche Sapphire from Thabeikkyin featuring a silvery-lilac background and noteworthy "spokes" or "legs" radiating from the center of the crystal. A cool stone for your collection, or it could be used as the center stone for a pendant or other piece of jewelry. Valued at $1,500. From the collection of Bill ("Burma Bill") Larson of Fallbrook, California (collection #569). Bill is a well-known gem and mineral dealer as well as a miner and collector. Bill traveled the world for decades in search of fine gems and minerals, and was directly involved in the in-person acquisition and importation of superb specimens and stones from Myanmar (Burma).
