Fire Opal Mining
DESCRIPTION:
According to the Greeks, the word "opal" means a change of color. Fire opal is a stunning gemstone with colors ranging from yellow to orange-red. Its name comes from the fiery orange hue it exhibits. Unlike precious opal, this stone may not display the same color flashes under light sources. Nevertheless, this beautiful gem was highly admired in countries like India, Central America, and other Persian kingdoms, believed to have been brought to Earth from a paradise filled with water due to its exceptional energy.
Historically, this gemstone was widely used by the natives of Mexico but gradually lost its significance. It was largely forgotten until the early eighteenth century when it regained popularity. Systematic mining efforts elevated its status to the national gemstone of Mexico.
Brazil is another significant source of this precious stone. The yellow-orange stones discovered there stand out for their beautiful color and impressive size, some as large as a man's fist. This gemstone has sparked new trends in the jewelry world. Not all fire opals are alike; those with vibrant colors are more valuable, regardless of whether they exhibit a play of colors. This flashy stone remains a top-quality gemstone.
Gem cutters have the liberty to shape these stones into various forms, taking advantage of their size. Oval cuts, for example, allow orange light to pass through, enhancing the stone's rich glow and increasing its value.
Careful cutting is essential to preserve the majestic color of the stone. It should be protected from heat, as uneven water distribution can cause cracking when artificially dried.
Fire opals maintain moisture balance and can be worn daily, but precautions should be taken to shield them from cosmetics. They can also be polished to restore their sparkling shine.
Known for imparting courage, stamina, energy, willpower, and a positive outlook on life to the wearer, this gem's value is determined by its play of color, body color, and transparency. Stones with intense color and high transparency command higher prices.
Despite the risk of cracking due to water content, this precious stone brings joy to its wearer and nurtures a love for nature. It stands as a vibrant gift from nature in its most splendid form.
