Buy amethyst - the value factors

Interplay of color, purity, cut and weight

Similar to diamonds, the value of which can be objectively determined using the detailed 4C

  • Color / color
  • Cut / polish
  • Clarity / purity
  • Carat / carat or weight

can be determined, the same criteria are used to determine the value of colored gemstones.


The color of amethyst

The color of amethysts is very varied and ranges from light, almost pastel shades of purple to strong, dark purple. Amethysts are somewhat less known and also less common pinkwhich are traded in professional circles under the name Rose de France Amethyst.

When assessing the quality of an amethyst, the color is examined in detail. Especially Dark purple amethysts with no discernible blue or red cast are very popular and correspondingly expensive, the so-called Deep Russian Amethyst or Siberian Amethyst. In the past, this name was only limited to stones from Russia, but the term Deep Russian Amethyst has now established itself as a predicate for the color of amethysts from all over the world that have precisely this color.

It is also considered whether the Color in the stone is evenly distributed or blotchy works.

And the question of whether an amethyst was subsequently subjected to a color treatment is also clarified. In the gemstone industry, it is not uncommon to upgrade or change the color of minerals afterwards.

Through a simple process called Burning, the color can intensify so that the stone appears darker and more even in color. However, this process requires a lot of experience and skill, because if an amethyst is heated above a temperature of 470 ° C, the color changes and the yellow quartz variety citrine is created. The fact that an amethyst has been color-refined is clear from a note when buying it in the form of, for example, "burnt amethyst", "treated amethyst" or "heated amethyst".

In addition to burning, the color of pale or spotty amethysts can be characterized by a fine layer corrected colored wax become. The stone to be treated is dipped in purple colored wax and coated with wax. In the case of cut or faceted stones, this step takes place after the grinding; otherwise the superficial wax layer would be removed.
For this reason, amethyst jewelry should be removed when washing hands, showering or cleaning, as shampoo, shower gel, soap and detergent can loosen the wax layer.

The purity of the amethyst

Amethysts are by nature relatively pure minerals.
Unlike many other minerals, the purple quartz variety has seldom inclusions from other minerals, gases or liquids.

However, should the purity be impaired, this can also be remedied with the help of burning. The impurities evaporate and the stone becomes flawless.

Although the term flawlessly appears much more frequently in connection with diamonds, it can also be applied to the purity of other minerals.

A stone is therefore defined as flawless if no defects in the stone (various inclusions) or external flaws (e.g. scratches, scrapes, grinding marks, broken corners and edges) can be seen even under 10x magnification with the magnifying glass. Stones in which no defects can be seen in and on the stone when viewed with the eye are defined as eye-clean.

One quality that plays a role in the purity of amethysts is transparency. Amethysts are characterized by a clear to opaque transparency, with clear, transparent specimens being favored on the market. The reason: the light is better reflected on the facets of transparent amethysts and there is a more intense play of color and nuances of the mineral's own color.


The size of amethysts

Amethysts are minerals whose crystals can produce considerable sizes.

When evaluating or determining the value of amethysts, a distinction must therefore be made between stones that are processed into jewelry and those that are left in their natural state, for example as a druse, gland segment, step or individual crystal.

The largest amethyst druse in the world - Empress of Uruguay - weighs 2.5 tons and is worth 170,000 US dollars.
On the other hand, you can buy a single amethyst tip for as little as € 5; smaller levels are sold from around € 10.

However, there is here Price differences due to origin of amethysts. Amethysts from Uruguay and Russia are considered to be particularly strong in color compared to lighter amethysts from Brazil.

When it comes to cut amethysts, there is a tendency for an amethyst with a higher carat weight to cost more than an amethyst of a smaller size.


The cut of amethysts

Amethysts are offered in all imaginable cuts. While cloudy, opaque amethysts with possibly existing drawings (waves, jagged edges) are processed into tumbled stones, donuts, pearls or cabochons, flawless, clear amethysts are made in faceted cuts (e.g. brilliant cut, pear-shaped cut, heart cut, oval cut, rectangular cut, emerald cut).

Due to the high amount of work involved faceted amethysts are classified higher priced than smooth cut stones are held.


The price of amethysts

The question "How much does an amethyst cost?" let yourself do not give a blanket answer.

There is no table showing the price of an amethyst with weight xyz in the cut abc.

Rather, the price of minerals and gemstones is a conglomerate of color, cut, weight and purity. All factors are compared, evaluated and weighted.

In the case of amethysts and other colored gemstones, however, it has emerged that color is placed above all other influencing variables.

The The color of amethysts is THE quality, which distinguishes amethysts and what the stone stands for. Nevertheless, there are trade-offs if the color is not natural, but the result of a color correction.

Compared to other gemstones, amethysts are comparatively inexpensive minerals with a high price range.

While pale purple amethyst with cloudy transparency for a few cents per carat sold cost exquisite specimens up to 100 euros per carat.

The fact that amethysts are among the affordable minerals is not ultimately due to them frequent occurrences of the mineral worldwide. Quartz and thus also the purple variety amethyst belong to the most common minerals on earth after the feldspars. A fact that is also reflected in the price of amethysts. Rare minerals such as larimar, tanzanite, musgravite, poudretteite, benitoite, charoite or Haüyn are classified as amethysts at a much higher price due to their few occurrences.
