Opal is a mineraloid gel that is applied to low temperatures and can occur in cracks in almost any type of rock. It is mainly found in limonite, sandstone and basalt. The water content of opal can be as high as 20% in a variety of colors from white to orange and black. Dark-resistant red is the rarest and most expensive due to the magnitude of the growth reaching red and infrared waves; these are precious opal. Opal earring is Australia’s national treasure. Opal is used in a variety of jewelry such as bracelets, earrings, pendants, cufflinks and bangles. The most common jewelry seen by opal and white gold together would be a ring.
Australian Opal Necklace is a mixture of gold and at least one white metal, usually nickel or palladium. Like yellow gold, purity of white gold is given to carats. White gold structures vary depending on the metal and the scales used. Nickel alloy is strong and durable so it is suitable for rings. High quality white gold is usually in 18 carats and is made of gold and palladium. Occasionally other metals such as copper, silver, and platinum are added to the weight and durability, though this often requires specialized goldsmiths.
opal and white gold are my favorite jewelry items. Opal is Australia’s national gemstone so many Australian jewelers are opal experts.
