What to look for
Turquoise is available in a wide range of sizes, although large pieces of turquoise without any visible matrix are rare. All sizes are used in Native American jewellery. Large sizes have been popular for carvings. For any size, the quality and evenness of the colour is the overriding value factor.
Turquoise Quality Factors: The Comprehensive Guide
Tips & Advice
1. Buy from a jeweller you trust.
Turquoise is commonly treated to improve its stability and colour. If you are looking for turquoise that has not been treated in any way, make sure your jeweller has the gemological expertise and knowledge.
2. Protect turquoise from chemicals and cosmetics.
Natural turquoise can absorb things like cleaning products, perfume, or metal polish, which may affect its colour. Remove turquoise jewellery when cleaning and applying products to your skin and put your turquoise on after using cosmetics and lotion.
3. Turquoise might gradually darken as it’s worn.
Because most turquoise is porous, it can absorb skin oil. Beads and rings that touch the skin can gradually darken as they absorb natural skin oils.
4. Fine quality turquoise has long-lasting beauty.
The best quality turquoise is harder and more durable. Turquoise jewellery has been found that is thousands of years old and still bright and beautiful.
