Ambylgonite Gemstones

What Is Amblygonite

To undertstand the meaning of the name Amblygonite, we  might need to get a bit technical but we will attempt to keep the technical hype to the minimum. Firstly let us understand that when you talk about amblygonite gem stones, the name ambligonite or amblygonite is used to refer to  the same stone. But if you want to be perfect in everything that you say or do, then spell the gemstone rightly as Amblygonite. Back to the technicalities of gemstones that we just referred too.

Getting to the basics let us talk about a piece of wood, about 1 foot long. If you took a chisel and hit the wooden piece in the right spot, the wood would split into two pieces. If you hit the same piece of wood in the wrong spot, the piece might scar but it would not crack or split easily. In everyday conversation we say that, the wood would split easily if it was hit in line with the grains, it would not split easily if it was hit 'against' the grains. Now let us move to gemstones with the same analogy, we refer to the concept of cleavage of the gemstone.

The cleavage is what will decide how resistent the gemstone is two a physical impact (not recommended that you try any such test with your gems). The cleavages for amblygonite are at obtuse angles, which means that the angle between the planes is more than 90 degrees. Equipped with this background information, we will now explain what the name ambligonyte means. The name is derived from two Greek words, which mean blunt and angle. The first part is the Greek word 'amblus' meaning blunt. The second Greek word is 'gouia' meaning angle. If all you are interested in is the amblygonite gem stone, you really need not worry about how the name was derived. The information is added here to make the report more comprehensive and complete.

Amblygonite is not always a gem stone, it is only when the mineral is transparent that it commands a price and value in the gems and jewelry market. It is basically a fluorophospate mineral composed of, lithium, sodium, aluminium, fluorite and hydroxide. Ambligonite that is not suitable for gemstones has some industrial applications. With lithium forming a 10% component of amblygonyte, it is used as a source for lithium. There is a scientific test known as the 'flame test' to determine the presence of lithium in a substance. We would not suggest that you try this but, here is how the test is performed and interpreted. If you made a powder of amblygonite, placed it in a spoon and exposed it to a gas flame, the flame would turn red. This proves the presence of lithium in ambligonyte. Once again, please do not try this test on your own.

If you had to talk about the sources of amblygonite, you need to know that most of the mineral is in an opaque form. Much of the coarse variety of ambligonite stone comes from the U.S and France. This is generally found in white or creamish white color, pale yellow or colorless amblygonite can also be found in natural form. Coming to gem quality amblygonite, the color is generally yellowish green or green. As expected you would want your ambligonite gemstones to have high transparency. Brazil is where most of the ambligonite gems come from. Some amount of  gem quality material is procured from Burma.

Another bit of technical jargon related to amblygonite, it is quite interesting though. When you talk about lithium and sodium content in ambligonite, lithium is present in a greater proportion as compared to sodium. Remember that amblygonite is often used as a source to extract lithium. You could come across specimens that have the same structure and chemistry as amblygonite but, with an important difference. In  this case the proportion of sodium exceeds that of lithium, this mineral would be more correctly referred to as natramblygonite and not amblygonite. In cases where fluorine is present in a smaller proportion as compared to hydroxide, the mineral would be called montebrasite. It is important to understand that montebrasite and ambligonite are structurally the same, however a very slight difference is physical properties is present.

One factor that could directly impact purchasing decisions related to gemstones is the durability of the stone. Sellers are aware of this and therefore withold information that they feel would negatively impact buying moods. This is basically a short sighted view as a buyer who loves amblygonite, would really to posess the gem. A better way would be to educate buyers and make them aware of issues that need their attention. Ambligonyte has a hardness of 5.5 - 6 on the Mohs scale - this scale goes up to a maximum 10 rating. Considering the amblygonyte has an average hardness, it is a good idea to restrict it's use in rings. We would recommend that you consider setting the gem in earrings or pendants. As you would surely agree, pendants and earrings go through far less wear and tear as compared to rings. You should keep amblygonyte stones and jewelry away from hard objects, this reduces the risk of the gemstone getting scratched. A very good practice when storing all types of jewelry is to keep each piece separated from others. A jewelry box with separate compartments for each jewel is the best way to go. We sometimes seem to forget that a jewel or gemstone could get scratched by rubbing against another jewel too. That is why bundling all jewels together in a storage bin is not recommended.

It is not uncommon for amblygonite to be confused with quartz or albite. While the external appearance of ambligonite could resemble these gems, it is technically quite easy to do an identification test. A gemologist could check the density and cleavage of the stone and also conduct a lithium flame test, to get a correct identification.
