Eudialyte Gemstone Information

eudialyte Gemstones

Eudialyte is a rare cyclosilicate mineral which was discovered in 1819 in the Julianehaab district of Greenland. It is a popular mineral in collections however due to its attractive and distinctive colors. Eudialyte's colors are quite pleasant and give the collector an all-together attractive and rare mineral. It can show distinctive colors of a red-violetmagenta, red, pink, blue, yellow and an attractive brown. Much of the eudialyte on the market today comes from the Kola Peninsula, Russia and one would be fortunate to add to one's collection of fine minerals from this wonderful site.
 

Why Buy Loose Gemstones Instead of Pre-Set Jewelry?
 
There are many reasons, but basically it boils down to value and choice.

When buying your Fluorite gemstone loose instead of a pre-set stone, you can be sure you are getting the best value for your money.  Loose gemstones are less expensive, a better value, and you can really see what you are paying for.  The most important part of getting the right price and finding the best value is to first see what you're getting. A jewelry setting will hide the inclusions inside a gem, and can deepen or brighten its color. With a loose stone you can much more easily inspect the gem and see it for what it really is.  In this way you can get a better idea of its true worth and be sure you are paying a fair price.

The second advantage of buying a loose gemstone is choice.  You are free to pick the exact color, cut, shape and variety of the stone for the setting of your dreams, be it yellow gold, white gold, platinum or silver; prong set or bezel set with diamond accents.  You can experience the joy of creating your very own, one-of-a-kind jewelry design. Choose from a variety of jewelry settings and styles to create a completely original presentation that will perfectly suit your individual gemstone and will be as unique as you are!

Eudialyte is a rare, red silicate mineral, which forms in alkaline igneous rocks, such as nepheline syenites and rarely forming good crystals and only occasionally forming any crystal faces at all. It is usually just a component of a host rock. Eudialyte is considered to be a potential source of zirconium in the future. The best samples of eudialyte have large semi-transparent crystals of deep red color embedded in matrix of black, gray and white.

Eudialyte rates a 5 - 6 on the mohs scale of hardness and has a refractive index of 1.598 - 1.602. The refractive index (RI), measured using a refractometer, is an indication of the amount light rays are bent by a mineral.Birefringence is the difference between the minimum and maximum RI. When birefringence is high, light rays reflect off different parts of the back of a stone causing an apparent doubling of the back facets when viewed through the front facet.

Most gems have a crystalline structur. Crystals have planes of symmetry and are divided into seven symmetry systems. The number of axes, their length, and their angle to each other determine the system to which a crystal belongs.  Eudialyte gemstones crystallize in the hexagonal crystal system.  Crystals are typically rhombohedral but can be long prisms.  It is most commonly massive or as a vein filling.

 

Color

Eudialyte occurs in distinctive colors of a red, magenta, pink, blue, yellow and an attractive brown. The intensely carmine color has been referred to as "Dragons Blood", by some Russian dealers.


Cut
 
For the most part, Eudialyte is cut into the cabochon shape or carvings for use in jewelry due to its poor crystal habit.

Sources
  
Eudialyte was discovered first in the Julianehaab district of Greenland in 1819, but now the most part of eudialyte on the market  comes from the Kola Peninsula in the northern part of Russia, the region that has produced over three hundred different mineral species and is the type locality for over a hundred minerals.  The other locations where eudialyte is found include Mont Saint-Hilaire, Quebec, Canada, Kangerdluarsuk , Greenland; the Langesundfjord region of Norway; Madagascar and Magnet Cove, Arkansas, USA.

The site at Kola Peninsula is one of several sites around the world that have a strange assortment of igneous minerals and are referred to as Agpaitic Pegmatites. These sites are unusually rich in alkali metals especially sodium. They also tend to be rich in what are sometimes termed "difficult elements", elements that are large and/or have unusual charges. These elements do not fit well into ordinary minerals and are thus excluded from earlier crystallized minerals and must wait for their opportunity to crystallize later. Examples of difficult elements are zirconium, beryllium, strontium, cerium, niobium, thorium, barium, yttrium and other rare earth elements. These normally scarce elements become highly concentrated, relatively speaking, and form some unique and wonderful mineral species. Eudialyte is an example of an unusual mineral that comes from these mineralogically unique sites. Not only is it rich in sodium, but has zirconium, cerium and often traces of yttrium in its structure. Eudialyte is considered to be a potential source of zirconium in the future.

 

Mythology
 
Eudialyte derives its name from the Greek eu and dialytos, meaning "well decomposable".  Its name alludes to its ready solubility in acid.

Eudialyte is a stone of the heart! It brings harmony into the heart matters, and dispells jealousy.

As eudialyte combines pink and red, it also brings the root and heart chakras into alignment, as well as activating the heart chakra.

Emotionally the Eudialyte gemstones is helpful for learning to trust oneself and others.

Eudialyte was discovered in 1819 in the Julianehaab district of Greenland.
