Popular Types of Opal and Tourmaline
Some well-known Opal varieties include:

Black Opal: Dark body colour that can make play-of-colour appear more dramatic.
Fire Opal: Usually yellow, orange or reddish-orange.
Boulder Opal: Opal naturally associated with its host rock.
Popular Tourmaline varieties include:
Rubellite: Pink to rich reddish-pink Tourmaline.
Green Tourmaline: Available in light to deep green shades.
Indicolite: Blue to blue-green Tourmaline.
Watermelon Tourmaline: Displays pink and green colour zones in the same gemstone.
Are Opal and Tourmaline Good for Everyday Jewellery?
Tourmaline can be used in rings, earrings, pendants and bracelets, but it should still be protected from hard knocks and scratches.
Opal is more delicate and requires additional care. It can be sensitive to impacts, sudden temperature changes and harsh cleaning methods.
For frequent wear, Opal earrings and pendants are often easier to maintain than rings.
Remove both gemstones before exercising, cleaning or doing activities that may damage the jewellery.
How to Choose October Birthstone Jewellery
When choosing Opal or Tourmaline jewellery, consider:
Colour: Choose the shade or colour pattern you personally like.
Appearance: For Opal, look at the quality and distribution of play-of-colour. For Tourmaline, look for an attractive colour and brightness.
Cut: A good cut should enhance the gemstone’s appearance.
Setting: A secure setting helps protect the gemstone.
Certification: For valuable gemstone jewellery, ask for an independent gemstone report.
Is Every Opal or Tourmaline Genuine?
No. Appearance alone cannot confirm whether a gemstone is natural.
Opal may be:
- Natural
- Synthetic
- Treated
- An assembled stone
- An imitation
Similarly, a colourful stone sold as Tourmaline may actually be another gemstone, glass or an imitation material.
Some gemstones may also receive treatments that alter their appearance.
This is why gemstone identity should not be confirmed only by colour or visual appearance.
Why IDT Certification Matters
IDT Gemological Laboratories examines gemstones using professional gemological instruments and testing methods.
An IDT Gemstone Identification Report can help provide information about:
- The gemstone’s identity
- Whether it is natural or synthetic, where applicable
- Detectable treatments
- Weight and measurements
Before purchasing valuable Opal or Tourmaline jewellery, always insist on IDT Certification and verify the report through IDT’s official verification platform.
