Yes, tungsten rings are safe. They are made from tungsten carbide, which is a compound of tungsten and carbon. Tungsten carbide is biocompatible and hypoallergenic and unlikely to cause skin irritation or allergic reactions, making it a good choice for people with sensitive skin.

Tungsten rings can be removed in emergency situations, because they will shatter under large amounts of pressure (unlike gold, which will bend).

• Shatters in emergencies: While difficult to remove during normal wear, if necessary, tungsten carbide rings can be shattered with specialized tools in emergency situations like finger swelling. This is actually safer than a ring that gets stuck and constricts the finger. 
  
• We suggest you purchase a ring that is not too tight give yourself some wiggle room! 

Many people also ask if tungsten rings are toxic. The answer is no.

Although pure tungsten is toxic and can cause issues, tungsten rings are made out of jewellery-grade tungsten carbide, which is safe and will cause no issues to the wearer.
