A good looking tie pin that has been set with a Flux emerald. French chemist Jacques Joseph Ebelman\u00a0developed the flux process to make emeralds in 1848. However, it was more expensive to synthesise emeralds than to mine them until 100 years later.\u00a0 The elements that make emeralds are dissolved in a heated solution with flux to aid in melting everything, all inside a platinum crucible (only flux emeralds may show platinum platelets in them). The solution is then heated for as long as the grower wants. It can take months to grow large crystals, with the size of the crystal proportional to the amount of time it spends growing. These emeralds were sought after in their own right.<\/p>\n
This tie pin that has been rub over set with a cabochon cut flux emerald was made circa 1910-1920 and is an interesting example of the technique.<\/p>\n
