PearOverview
Opal is a gorgeous semi-precious gemstone that has been alluring people for centuries with its distinct beauty. It is famed for showcasing a vivid play-of-colour, the term ‘play-of-colour’ can be described as an optical phenomenon that causes the gem to flash various hues and patterns when it is moved or due to a reaction with light.
This stone’s popularity dwindled considerably when author Sir Walter Scott’s novel "Anne of Geierstein" was published in the year 1829. The story gave the impression that opal was demonic and wearing it would bring bad luck. It is believed that this caused the opal market to crash and price dropped by almost 50 percent.
1. Key Origin
- Approximately 97% of the world's opal supply comes from Australia.
- This gem is also mined in Mexico and several other countries across the globe.
- Opals that display black and red hues are extremely rare.
2. Associations
- Throughout the ages, opal was considered to be a powerful stone that induced mystical vision and enhanced creativity
- The Romans associated opal with fidelity, hope and purity, while the early Greeks believed it could foretell the future.
Properties
Rated 5 to 6.5 on the Mohs scale of mineral hardness
01Hardness & Strength
Opals are delicate and score a rating of 5.5 - 6.5 on Mohs scale of mineral hardness, which means they are susceptible to scratches and breakage. Shallow crazing (surface cracks) if filled correctly will only make a small deduction in value. Fractures will drastically reduce their price and cracked opals are not suitable for jewellery. Additional care needs to be taken if you intend to wear an opal ring, bracelet, necklace or earrings on a daily basis.
02Treatment
Opals are generally untreated, but enhancements are often done to improve their appearance and durability. While there are a number of methods that are utilized to bring out their play-of-colour, sugar and smoke treatment remain the most common.
Opal is wrapped in paper before being subjected to heat and smoke. This causes the particles of soot to penetrate the surface of the gem, giving it a darker background colour and elevating the play-of-colour.
