Rare Color

Here are some more information for Rare Color:

Traditionally, diamonds are mined for its colorless florescent perfection. So why is a pink diamond not seen as a devalued flaw of imperfection and carry such importance in the marketplace?

Naturally, colored diamonds are extremely rare and enormously expensive. During the formation of the carbon below the earth's plates, curtain minerals and composites were present as the carbon crystallized by pressure then heat. These complex minerals became trapped inside at some stage in the crystallizing process of the carbon, the premature diamond. This protected the mineral or element inclusion from escaping and becoming vaporized by the heat.

The mysterious pink diamond is mined in India, Brazil and in Africa. Although, the Argyle Diamond Mine, in Western Australia, remains the largest producer of the pink diamond. Unlike the kimberlitic plates in India, Brazil, and Africa, the Argyle Diamond Mine produces its pink diamonds from a rock formation called lamproite. Which may give the insight as to why, the mine produces the most brilliant and spectacular display of natural pink diamonds in the world.

Scientists as well as top gemologists from around the world have yet to discover the exact element or elements that produce the pink hue in a pink diamond.

Some scientific theories have surfaced though. There is a theory among scientists that the pink hue is a reflection from a crystal deformation. This would explain the florescent pink hue presence even within such a clear atomically correct diamond. Scientist has yet to prove their theory though or to isolate the crystal deformation.

Gemologists believe the pink hue is not created from any of the elements in the periodic table. Gemologists claim that tiny abrasions along the diamonds multiple grains are responsible for reflecting the pink hue.

Meaning, a pink diamond only has the appearance of a pink hue and not that of a true mineral or element nature. Gemologists have based this theory on the fact that the pink diamonds found in the Argyle Diamond Mine are clear under microscopic evaluation.

Currently the Gemological Institute of America has categorized the fancy pink diamonds into five different primary color grades. The color classifications are pink, purplish pink, brownish pink, orange-ish pink and pink champagne.

Despite the mysteries of the pink diamond, it remains an exquisite find and is favored by wholesale jewelers from around the world. A natural pure untreated pink diamond is defiantly limited in quantity. Only a fraction of one percent mined from the largest pink diamond mines have said to be recoverable.

Gemologist Engineers overseeing the Argyle Diamond Mine expect that the region will be depleted by year 2017, in which the pink diamond will no longer be replenished in the marketplace. The Argyle Diamond Mines are known to be the only pink diamond producer of its kind.

With the prospect of supply depletion of the pink diamond, the diamond market can look forward to the fact that the already rare fancy pink diamond will remain a prized and rare jewelry collectors item and possibly subject to being considered as valuable as the famous diamonds that are currently displayed and kept by museums around the world.

Gemstones That Guarantee Natural Color And Rarity

Gemstones in beautiful, striking colors look so captivating but how many of us know that most of their colors are not natural and that they are artificially treated to obtain those colors!

Most of the gemstones undergo some treatment to enhance the color and durability. Many treatments alter the color of the stone significantly. Mostly rubies and sapphires are subjected to artificial processes like high temperature heating to alter the color or clarity of these stones. Sometimes foreign substances are included which change the chemical nature of the stone entirely and thus, change the color. Blue topaz is one example which is colorless in its natural form but irradiation and heating changes its color permanently. Citrine, pink topaz, tanzanite are some stones on which treatments are considered acceptable and to keep these stones affordable also, such treatments are necessary. Some treatments are permanent and can not be detected easily. However, there are other treatments which are not too permanent and not stable.

Most common treatments which are given to gemstones are heating, oiling (usually on emeralds), irradiation, dyeing, impregnation (wax infusion), bleaching, coating, diffusion (on sapphires), filling and lasering. Of these, heating is most common treatment given to stones. The color of the stone can be lightened, darkened, or completely changed; can improve the clarity of the stone through the heating treatment. This process is irreversible and can only be detected in laboratories.

Though the resultant stone looks very appealing to the eye in terms of color and clarity it will not be considered truly natural and untouched. Also, it will not count as rare because one can find many such fabricated stones anywhere else. Most natural gemstones are far from beautiful and in fact they undergo treatment to enhance their appearance. Natural, unheated, or untreated gemstones are extremely rare to find and thus they are very highly priced. There are certain stones which are not treated like most Garnets, Peridot, Lolite, Spinel, tourmaline, malachite.

For some people a gemstone in its natural color is a prized possession and most of its appeal lies in the fact that it is not enhanced and untreated. But for many people, price still is the deciding factor and they go for the cheaper stones which mostly are the treated gemstones. There is a market for every kind of stone, treated, imitated, lab created, and natural. Depending on the end use of the gemstone, the buyer should buy the stone. A buyer has the right to know the correct information about the stone. The seller should disclose this information to the buyer at the time of purchase. There are companies which sell truly natural gems with a certificate attached to the stones which authenticate the claim. For collection pieces, one should go for rare and untreated, natural gemstones.

Do you think my betta fish color rare?

He has a Navy Blue body and yellow fins so is it rare

not necessarily...i have seen several blue and yellow bettas at pet stores before.
Bi-colored bettas are rather common; as are full blue ones.
Now if he was completely yellow, now that would be quite rare.
