Aventurine, Shimmering Beauty

Aventurine And Glitter

Aventurine is a variant of quartz though not as popular as Amethyst or Citrine, which also belong to the quartz family. If you wonder from where the aventurine gem stone got it's name, it is interesting to know that the word is picked up from the Italian language. The term 'a ventura' in Italian means 'by chance', the name aventurine is a variation of this. We do not know for sure why the name was influenced by Italian because, the stone is in not very abundant in that nation. Most of the greenish aventurine stones originate from India.

Aventurine is basically a transluscent variety of quartz and is generally white with many (colored) inclusions. When you talk about a green aventurine gem stone, you refer to a transluscent or opaque quartz that has green inclusions in it. Gem buyers do sometimes come across aventurine gems that are opaque with almost no transluscency. The point is that in such opaque aventurine gemstones, the inclusions are so densely packed that they do not allow any light to pass through them. So you can have aventurine stones where the inclusions are very scarce, others where there are moderately concentrated inclusions and finally, aventurine with densely packed inclusions.  

Let us talk about the color of aventurine gemstones. As mentioned above, the base color is a transluscent white that is quartz. Many gem buyers including very experienced ones believe that, aventurine is always greenish implying that the inclusions are always green. The truth is that this stone has quite a few color variations. Brown, green, blue, yellow and even grey are the main colors in which aventurine gemstones can be found. Once again it is the element that is included in the stone that imparts the color to it.

The green aventurine stones have a type of mica present in the stone in the form of tiny flakes. This mica type is referred to as, fuchsite and the presence of chromium in fuchsite gives it a green color. Just how green your aventurine gemstone would appear, depends on the concentration of the green fuchsite flakes in the gem stone. They can sometimes be so dense, that the rough stone is mistaken for some other green gems.

If you hold an aventurine stone in the light, you will see an impressive shimmer in the gemstone. This is brought about by the light striking the inclusions. If the gem stone is oriented in the right direction during the cutting process, the shimmer can be truly spectacular. As expected, aventurine gem stones that are very sparsely included or very densely included do not appear very pretty in the light. This shimmer has been given a technical name by gemological experts, they named it aventurescence. Keep in mind that this type of shimmer has been given the name aventurescence. If the same shimmer exists in another gem stone which is not aventurine, the effect can still be called aventurescence.

Most reports rate the hardness of aventurine at 6.5 to 7. Pure quartz would measure a whole 7 on the Mohs scale but since aventurine is not quartz alone but includes other elements, the hardness is a little below 7. You will find aventurine cut into faceted gems and even smooth (cabachon cuts). Beads are one other popular way in which aventurine is cut. Much of the demand for aventurine gemstones is sustained by the special meaning and powers attached to it. Many people believe that wearing an aventurine stone stimulates creativity. Managers who wear this stone are believed to make good leaders with sharp and prompt decision making. Please remember that we do not make any such claims about any gemstone.
