Colour is only one part of the decision. Think about how the piece will be worn, how it will be set, and what care it will require.
| Jewellery Type | What to Consider | Practical Guidance |
|---|---|---|
| Rings | Frequent impact, abrasion and contact with hard surfaces. | Prioritise durability and protective settings. Softer or cleavage-prone stones may need extra care. |
| Necklaces and Pendants | Stone weight, exposed edges and contact with clothing or skin. | Choose a secure setting and check the pendant’s edges and bail. |
| Earrings | Weight, setting security and ease of wearing. | Lightweight designs can be more comfortable for extended wear. |
| Bracelets | Repeated knocks, friction and contact with surfaces. | Beads and softer stones may scratch or chip; inspect stringing and clasps regularly. |
| Occasional Jewellery | Visual effect, colour, rarity and the intended occasion. | Less frequently worn pieces may allow more delicate materials, provided they are stored and handled appropriately. |
Understand Hardness and Toughness
Mohs hardness describes resistance to scratching; it does not measure resistance to breaking or chipping. A gemstone with relatively high hardness may still be vulnerable to impact, cleavage or damage around exposed edges.
Before You Purchase
Confirm the material
Ask whether the stone is natural, laboratory-grown, imitation, assembled or treated.
Ask about treatments
Request disclosure of known dyeing, heating, coating, impregnation or other treatments.
Check the setting
Inspect claws, bezels, links, clasps and other parts that hold the gemstone in place.
Review seller information
Check product descriptions, photographs, return policies and any accompanying reports.
Jewellery Care and Maintenance
Different gemstones react differently to heat, chemicals, sunlight, moisture and cleaning methods. Always choose care instructions suitable for the specific stone and setting.
Clean gently
Use a soft cloth and, where appropriate, mild soapy water. Check whether the stone can safely be immersed.
Avoid unsuitable cleaners
Ultrasonic cleaners, steam, harsh chemicals and sudden temperature changes may damage some stones or settings.
Store pieces separately
Separate jewellery to reduce scratching and accidental impacts between stones and metal components.
Inspect regularly
Check for loose stones, worn settings, damaged clasps, chips and visible surface changes.
Frequently Asked Questions
Which crystals are suitable for everyday jewellery?
Suitability depends on hardness, toughness, cleavage, setting and lifestyle. Quartz varieties such as amethyst and clear quartz have a Mohs hardness of 7, but still need protection from hard impacts and damaging conditions.
Is a harder gemstone always more durable?
No. Hardness measures scratch resistance, while toughness concerns resistance to breaking or chipping. Cleavage, inclusions, cut and setting design also affect practical durability.
Should I ask whether a crystal has been treated?
Yes. Treatment information can affect appearance, care requirements, durability and value. Ask the seller to disclose known treatments and describe the material accurately.
Do crystals have scientifically established healing effects?
Gemstones have cultural, personal and symbolic significance for many people, but claims that crystals treat medical conditions are not established by reliable scientific evidence. Crystal jewellery should not replace medical care.
Can I use the same cleaning method for every gemstone?
No. Some stones and treatments are sensitive to heat, chemicals, water or ultrasonic cleaning. Confirm suitable care instructions for the particular gemstone and its setting.
