Baotite: a less recognized mineral

The picture below displays baotite minerals, in particular the faceted stone, which weighs 8.73 carats, and the crystal weight, which is 57 carats. The origin of this mineral is from the Zagi Mountains in the Khyber District of Khyber Pakhtunkhwa, Pakistan.

Baotite is a rare mineral composed of barium, titanium, niobium, and silicate. It was initially discovered in 1959 at the Bayan Obo deposit in the Baotou League, located in the Inner Mongolia Autonomous Region of China. The mineral was named after the locality where it was found.

How to Identify Aquamarine-Filled with Colored Polymer Type of Treatment: Impregnated

This article introduces a simple and non-destructive method to identify impregnated treatments in aquamarine.

Basically, what happens is that fractures in the aquamarine are filled with a polymer mixed with dyeing material. This not only enhances the color of the aquamarine but also hides the fractures.

The result is a beautiful, polymer-filled aquamarine that is often sold under the name of Santa Maria Aquamarine. Most of these treated aquamarines come from China (in bead shapes, making bracelets or other jewelers items) and Thailand (in faceted and cabochon shapes).

Gemstone traders purchase them at wholesale prices and then sell them at retail prices on social media platforms, eBay, or other e-commerce networks.

To identify a specific type of treatment in aquamarine, here's what you need to do: Grab the stone with a stone tweezer or simply use your fingers. Then, position a source of white light (fluorescent light / LED light preferable) behind the stone, just like you can see in the pictures that come with this guide.

Now, pay close attention to the stone and look out for any blue flashes or a cloudy appearance. You can see an example of this in the picture below.

Note the strong bluish fleshes

If you want to dig deeper and get more detailed observations, you can use a 10x loupe or a gemological microscope. Take a closer look at the color concentration within cracks and fractures, and who knows, you might even spot some air bubbles.

By following these steps, you'll be able to identify the treatment that has been done on your aquamarine. So go ahead and give it a try!
