Tanzanite

Tanzanite is a blue, violet, or purple gemstone and is the alternate birthstone for the month of December. It is a relatively hard gemstone, earning a score of 6.7 to 7 out of 10 on the Mohs Scale of Hardness. However, to keep the brilliance of his beautiful stone, care should be taken to keep it safe from scratches and sharp blows.
Connoisseurs Tip: Tanzanite is often treated with low-level heat to eliminate brown color and produce its desired violet-blue hue. This is a widely accepted gemological practice, which will be disclosed at the point of sale. Just as you should guard against sharp blows, so too should you avoid exposing your tanzanite to extreme temperatures.
The best way to clean a tanzanite that is set in gold or platinum is to use Connoisseurs Dazzle Drops Advanced Jewellery Cleaner. With this non-toxic cleanser, you can utilize a fresh solution every time you clean for the most effective results. You can also try Connoisseurs Fine Jewellery Cleaner in the familiar red jar.
If your tanzanite jewellery is set in silver, use Connoisseurs Dazzle Drops Silver Jewellery Cleansing Crème. This solution cleans and removes tarnish from silver and is safe to use on all gemstones.
We do not recommend ultrasonic machines or steam cleaners for tanzanite. However, our LaSonic Safewave or LaSonic Jewellery Bath are both deemed safe.
