Rubellite Tourmaline, Kalli Oval, Nigeria, #661
Zoom

Stone : Rubellite Tourmaline
Cut By : Doug Menadue, 2014
Item : #661
Design : Kalli Oval (Doug Menadue)
Origin : Nigeria
Treatments : None
Weight : 9.1 Carat
Clarity : Eye Clean
Size : 10.6x12.5x11.4 mm
Price : SOLD

Comments : This is truly a one-of-a-kind gemstone. This is a beautiful piece of rubellite tourmaline, eye clean with deep rich colours. The design was inspired by the round design called 'Kalli' by Jeff Graham. I created it specifically for this tourmaline. It is a very challenging design to facet but the results are worth it. In the sunlight the colour shows a very bright hot pink with lots of fire and action and there are many hues in this stone right through to rubellite. There are purples, violets, pinks and reds. It is truly unique and a connoisseur's stone.

When I first took it off the dopstick and out into the sun it took my breath away. The pics just can't capture how stunning this gem is. It just lit up like a pink ball of fire... as if the sun came down and decided to throw a party inside. The colour is like a hot deep candy pink when the sun lit it up.

If you did want to set it in a piece of jewellery then it would suit a bezel setting of some kind. It has a high dome, much like a high domed cabochon except with lots and lots of facets... 201 facets to be precise. A true masterpiece and a fine example of the gemcutter's art.

Comments : Here ia a stunning rubellite tourmaline cut in the classic 'Asscher' design. Colourwise I would class it as a rubellite and referring to the trusty Old Holland oil masters colour chart I'd say there are hints of cobolt violet light and scheveningen violet with deep salmon pink highlights... the pics really don't do justice to this gem. It is a beautiful gem, richly coloured, eye clean and an excellent size for a ring stone. Superb!

Comments : A superb pink tourmaline from Afghanistan! I truly love the Afghani tourmaline, it always cuts a bright, lively and good looking gemstone. This beauty has been faceted in my Acorn design and would be ideal for a creative solitare setting or perhaps a hanging pendant design. The colour is devine and as pink as you could want. In the sunlight the gem is dazzling with fire and sparkles. The gem is eye clean and first class, top shelf.

Clarity : Very Very Slightly Included

Comments : Here are two of the finest Afghan tourmalines of this type that you could hope to find. They are exceptional gems in every regard and they are very well matched which makes them even rarer. I have cut them in the modern classic Smith Bar design. This design is one of my favorites and works so well in tourmaline. One of them has a noticeable blue zone near one end and the other has a touch of blue but its not as noticeable. They are very close to eye clean with just a few small minor inclusions near the ends. They would make a very special pair of earrings or perhaps a pair of cufflinks. Alternatively they would make very good investment or collector gems. This pair of gems is a very special and rare offering, truly unique. These gems will be sold as a pair. This is a unique opportunity to own a very fine pair of Afghan tourmalines.

Comments : Tourmaline is a gem that comes in almost every colour imaginable and often in breathtaking combinations. It is thought that the Dutch, importing it from Sri Lanka to Europe in the early 1700's gave it the Sinhalese name, Turamali, meaning "stone with mixed colors". Gems with two or three colors are much sort after, such as blue/greens, mint greens/clear, pink/greens and gold/red. For example, a certain mixture of colours is called watermelon tourmaline where, cut in a cross section, the outer rind appears green whilst the inside is pink. Pinks (intense hot pink and light bubblegum pink), reds and blues are the most desired colors. Some tourmaline gems are treated in order to improve their colour.

In the last 20 years tourmaline has gained great popularity among gem collectors and the gem buying public because of its beauty, availablity and myriad colors. It cuts a stunning gem and suits almost all design styles. Fine examples of tourmaline can be obtained in relatively large sizes though 2 - 10 carats is a popular size range. Tourmaline often has inclusions and eye clean gems are the most desirable. Tourmaline forms as beautiful long crystals and are a great favorite among mineral specimen collectors. This stone can also be found in alluvial deposits as water worn nodules.

A curious property of tourmaline is that when heated and cooled, or by applied pressure, it will become electrically charged (pyro and piezo electricty). The charged stone can attract pieces of paper and dust. It was also used to pull ash out of meerschaum pipes by the Dutch who understood this property of tourmaline. They called tourmaline "aschentrekker" (ash puller).

One thing that can affect the colour and arguably the "quality" and price of a tourmaline gem is if it has what's called a
closed "C" axis. What does this mean? Well, given a tourmaline crystal in its original shape, if you look down the crystal (as if you were looking down a metal pipe) and it appears black or very very dark, this tourmaline is said to be "closed", like pulling a curtain across a window. If you can clearly see down the crystal even though the colour may change slightly, eg. a pink tourmaline might look peachy down the "C" axis, it is said to be "open". When a tourmaline with a closed "C" axis is cut, the resulting gem will in all likelihood appear darkish, especially around the ends if it is a rectangluar design. All things being equal, an "open" gem should demand a higher price then a "closed" gem. You can see an example of an open "C" axis tourmaline in the rough here.
