[TG_INTRO]
Opal is a captivating gemstone admired for its beautiful play-of-colour, which can display flashes of green, blue, orange, red and other colours as the stone moves in the light. Each opal has its own distinctive appearance, making it a popular choice for gemstone collectors, jewellery lovers and people seeking a unique natural gemstone. At Tanishq Gems, explore opal gemstones selected for their colour, pattern and individual character.
[/TG_INTRO]

[TG_ORIGIN]
Natural opals are found in several parts of the world, with Australia being one of the most famous sources. Other sources include Ethiopia, Mexico and Brazil. Opal varieties differ in body colour, transparency, pattern and play-of-colour depending on their type and geological origin. The exact origin of an individual gemstone should be confirmed through reliable documentation or gemological testing where available.

[TG_PRICE]
Opal prices vary considerably according to the variety, body colour, brightness and pattern of play-of-colour, transparency, size, origin, treatments and overall quality. Fine black opal and vivid precious opal can command higher prices, while common opal and lower-grade material may be more affordable. Ethiopian, Australian and other opals should be compared by their individual quality and any known treatments rather than origin alone. Contact Tanishq Gems for current availability and pricing.

[TG_CARE]
Opal requires more careful handling than harder gemstones because it is relatively soft and may be sensitive to sudden temperature changes, impacts and drying conditions. Avoid ultrasonic cleaners, steam cleaning, harsh chemicals and abrasive materials. Clean gently with a soft cloth and, when appropriate for the specific opal, a little lukewarm water. Avoid prolonged exposure to heat or direct sunlight, and store separately from harder gemstones to prevent scratches. Doublets and triplets, which contain assembled layers, may require additional care and should not be soaked unless the seller confirms it is safe.

[/TG_FAQ]

[TG_FAQ question=”Is opal suitable for everyday jewellery?”]
Opal can be used in jewellery, but its moderate hardness and sensitivity to impact make it less suitable for jewellery exposed to frequent knocks. Protective settings and careful wear are recommended, especially for rings.

[TG_FAQ question=”How can I tell if an opal is natural or treated?”]

Price depends on the variety, brightness and pattern of colour play, body colour, size, transparency, condition, origin and any treatments. The quality of each individual stone is important when comparing prices.
