It wasn't until 2000 until the first gem quality poudretteite was found in Mogok, Burma at an amazing 9.41 carats (pictured above). Painite is a deep, orange-red or brownish red stone that was found in Mynamar in the 1950s. Shortly after its discovery, the government of Myanmar (then known as Burma) fell to a military coup resulting in a dictatorship lasted until 2011. For decades, problems in Myanmar prevented more than a handful of samples from being discovered, but today more than 1,000 crystals are known to exist.
D is totally colorless, without a hint of any other color. Y indicates an intense deep yellow or deep yellow-brown. The letters between D and Y describe the color, depending on the amount of yellow saturation. The color bar below depicts the letter and the color saturation it represents.

This is not a measure of how young or cute the stone looks, but mostly a marketing term designed to make certain stones seem more rare or important than others. Diamonds, emeralds, rubies and sapphires are all considered to be precious, and thereby (according to the sales people) the most valuable and most desirable. All other gemstones are considered semi-precious.
Gemstones are classified into different groups, species, and varieties.[6] For example, ruby is the red variety of the species corundum, while any other color of corundum is considered sapphire. Other examples are the emerald (green), aquamarine (blue), red beryl (red), goshenite (colorless), heliodor (yellow) and morganite (pink), which are all varieties of the mineral species beryl.
Opals can form in a variety of different colors depending on the environmental conditions during formation. The mineralogy of opal allows it to diffract light, causing it to shimmer various colors. The cost of a ruby is primarily decided by its color.
It may be 0,1% of diamond jewels in color with nitrogen. Colorless diamonds are usually pure carbon, but diamonds of various exotic shades are almost always color of small impurities in the structure of the stone. The only difference between lead and diamond is the way the molecules meet. Graphite is a soft carbon form that easily converges to paper, and diamond is the most difficult known natural substance. Diamonds are mineral, natural crystalline element, transparent carbon or almost pure carbon.
White diamonds, unlike pink diamonds, are produced all over the world and are available in various shapes and sizes. The white diamond shows the pink stripes on the upper side. These are more expensive, and their depth and strength determine the price. It is the only mineral stone that consists of one element that makes it the purest jewel on earth.
High-quality Emeralds are produced in Colombia, Zambia, and Brazil. Colombia produces the best Emeralds in this world.Emerald is a sign of status and power and has been being the favorite of Royal Families.
Are gems a good investment?
Indeed, for some gems, such as diamonds, the price per carat can increase exponentially as the gem size increases. Therefore, a 1 carat stone may cost $1,000 while a 2 carat stone may cost $4,000. This means that good quality sapphires and rubies in larger sizes tend to have a much higher price per carat.
Spinel Gemstone Meaning
Most greened quartz (Oro Verde) is also irradiated to achieve the yellow-green color. Diamonds are irradiated to produce fancy-color diamonds (which occur naturally, though rarely in gem quality). A few gemstones are used as gems in the crystal or other form in which they are found. Most however, are cut and polished for usage as jewelry.
- The reason being opal does not have a crystal structure that is required for all minerals.
- However, this is the industry standard and all Gold jewelry is made with non-pure alloyed Gold.
- Boron is another element that can paint diamonds.
- Those born in the beginning of the year get a blood red birthstone.
USES Diamond is the most important gemstone in the jewelry industry. The colorless stone is most often used for jewelry, although yellows and browns are also used. (Brown stones are often marketed as "chocolate", "cognac", or"champagne" Diamonds, depending on color depth). Other fancies are too rare and expensive for the mainstream jewelry industry, and are exclusively reserved for the high end consumer.
Much planning must be taken before cutting a Diamond, as a slight error in the facet may significantly decrease the value of the stone. The color of a Diamond is graded on an alphabetical scale ranging from the letters D to Y. This scale measures the color saturation, ranging from absolutely colorless to deep yellow (or yellow-brown).
How many precious stones are there?
Rubies. Rubies, beautiful blood red stones, are rarer still than either emeralds or diamonds. Although synthetic and manufactured composite rubies abound, a genuine, untreated and pure ruby of good size and flawless coloration is easily the most valuable birthstone in the bunch.

However, there are a few interesting gemstones that are so rare, so lovely, and so desired that they are worth more than diamonds per carat. SIMILAR GEMSTONES Many metallic alloys can resemble Gold, and they can sometimes be difficult to tell apart from true gold. Professional analysis to inspect physical properties is sometimes required to distinguish Gold from other precious metals as well as cheap alloys. Diamond is recognized as the king of precious gemstones. The chemical composition of diamonds is 99.98% carbon.

UNDERSTANDING THE FOUR MAIN PRECIOUS STONES. Diamonds, rubies, sapphires and emeralds are four of the most valuable and sought-after gemstones in the world.
A ruby appears red because it absorbs all the other colors of white light, while reflecting the red. Green gold was known to the Lydians as long ago as 860 BC under the name electrum, a naturally occurring alloy of silver and gold.[3] It actually appears as greenish-yellow rather than green. Fired enamels adhere better to these alloys than to pure gold. Up to 15% zinc can be added to copper-rich alloys to change their color to reddish yellow or dark yellow.[2] 14K red gold, often found in the Middle East, contains 41.67% copper.

Is a Pearl a gem?
Pure gold is slightly reddish yellow in color, but colored gold in various other colors can be produced. Colored golds can be classified in three groups: Alloys with silver and copper in various proportions, producing white, yellow, green and red golds. These are typically malleable alloys.
The value of any mineral is based in part on its rarity, in part on its properties, and in part on its demand. Some gems, like diamonds and sapphires, will likely always be popular, while others like peridot and amethyst have varied in popularity over the centuries. All gems, regardless of cost or popularity, have unique properties and may be considered beautiful.

It was created in conditions of temperature and pressure that are almost unimaginable. It is created deep underground and shaped at a depth of 90 to 120 miles or more. The pressure is about 45 to 60 kilobar at these depths. However, the temperature at which diamonds are formed is considered relatively small due to this great depth. Usually, the color intensity gets more importance in color estimation.
