Because of the perfect cleavage this precious stone should not be pushed against a other hard edge since the stone can break. To chemical reagents the stone is generally insensitive. High temperatures on the other hand can cauterize the stone. Hence special care in solders is needed when producing diamond jewelry.

The typical brilliance creates stunning optical effects and the hardness and rarity the diamond is also known as the king of gems and used since ancient times for decorative purposes such as jewelry as you can see at Sapphires Diamonds and Pearl Jewelry and the Diamond brooch with Star Sapphire. Color diamonds command a high price at auction. Christie's sold a much smaller 13.39 carat blue diamond for $8.9 million, a great collection of beautiful diamond pendants jewelry at Ross- Simons.

Yellow diamonds are in this days,

mounted in a beautiful ring, as a pendant, diamond earrings or just a solitaire it looks real good, together with some gold or platinum  they fetch high prices, the same is with a pink diamond. The 603 carat white diamond, the Lesotho Promise was sold in Antwerp for US$12.36 million.

There are diamond mines on all continents with variable output and quality and different methods of mining. Most diamond stones produced are used for industrial purposes.

The stone above was recovered at Letseng mines in Lesotho, southern Africa. The Mine is owned and operated by Gem Diamond Mining Company of Africa Ltd, with its 30% partner the Government of the Kingdom of Lesotho, more.

Probable the most beautiful and valuable jewelry today are color diamonds

such as a pink diamond set in gold and the right diamonds cut give a perfect ring. One  can say a lot about carat and diamonds cut but today's fashion is tending to Princess cut and Asscher cut diamonds since they reflects the light like no other cut and they hide some impurities in a clever cutting manner. However in which direction you turn it, a diamond is the king of gemstone and a ruby gemstone is the undisputable queen.

Diamond Ruby is a great combination to form a good looking and creative piece of jewelry. The ruby give a mysterious deep red and the diamonds are sparkling, there is no fire in the ruby it wont matter how its cut and polished and that is what a diamond brings into. Sometimes there is a combination of blue and red means sapphire and gold ruby but usually its with the white transparent stone.

A engagement ring with this setting plus maybe yellow gold is probably the ultimate gift to show feelings and appreciation. Rubies are often even higher valued considering the size and clarity than a similar sized and clear diamond, read more.

Traditionally, colorless and flawless stones fetch the higher prices.

This is changing, driven by celebrities such as Victoria Beckham,

Jennifer Lopez and other. They have a great pink stones from the Argyle Mine in Australia and they show it. Pink diamonds from that mine can fetch about 10 times the price as a normal white stone of similar quality and size. The stone right above costs as much as a nice fully equipped Rolls Royce.

By nature color diamonds are rare and expensive. During formation of the carbon deep inside the earth certain minerals were present as the carbon crystallized by pressure and heat. These minerals became trapped inside during the process of crystallizing of the carbon; the outcome of this process is a colored stone since this inclusions couldn't escape.

Usually pink diamonds have been mined in India, Brazil and Africa, but now the Argyle Diamond Mine is the largest producer of pink diamonds. The pink diamonds  

mined in India, Brazil and Africa come out from a geological formation called kimberlitic plates. In the Argyle mine pink diamonds come from a rock formation called lamproite. Volcanic magmas solidify into kimberlite and lamproite but are not the source of diamonds. They are only the riser that bring them together with other minerals and mantle rocks to Earth's surface. Although rising from much greater depths than other magmas, these pipes and volcanic cones are quite small and rare.

It is not very clear what produces the pink hue. Some guess that the pink hue is a reflection from a crystal distortion. This would explain the florescent pink hue presence. Gemologists believe the pink hue is not created from any element trapped inside; it rather looks as if tiny abrasions along the diamonds multiple grains are responsible. The pink diamonds found in the Argyle diamond mine are clear under the microscopic which is rather unusual since every precious stone has some flows under the microscope, there are practically no flawless stones unless they are created diamond.

A famous pink diamond ring

 these days mostly comes with a stone from the Argyle Mine in Australia and this colored stones looks real good.  A new pink diamond ring is the dream of many women including certain celebrities such as Madonna and others. Pink Asscher-cut engagement ring from Harry Winston are difficult to find but there are enough other jewelry stores who supply them in different qualities, sizes and colors since pink is not pink all the time, there plenty of shades of pink.

This jewelry got a certain top status after the rumors spread that celebrities are buying them, they need plenty of cash since presently they come more or less only from one source, the Argyle Mine in Australia and if there is almost only one source of an item prices rise.

Pink diamonds are classified into five color grades, this are pink, brownish pink, orange pink, purplish pink and pink champagne. With the prospect of supply depletion by year 2017, the market can look forward to the fact that the already rare pink stone will remain a prized and rare collectors. Possibly subject to being considered as valuable as the famous diamonds that are currently displayed and kept by museums around the world.

In the new age companies such as Cartier, Van Cleef & Arpels,

Harry Winston and Tiffany are producing high end jewelry and they did a good job, but sometimes not so good. I still have a Harry Winston timepiece called watch for about $ 10.000. It was, over years not possible to wear since Harry Winston cant fix a bracelet or band on it which would last for more than 3 month. I took this to Harry Winston in Geneva for repair, no way, they are too stupid to fix the band to the timepiece lasting for more than 3 month and this went on for about 12 years. Stay away from this company they are amateurs even worst than a watch band seller at the Patpong night market at Bangkok, Thailand, you know where the Thai Bar Girls and go-go girls are. The guy fixed this in 15 minutes and after it was always ok, he took 2 dollars to fix, Harry Winston takes $ 200,- and fixes nothing. Unfortunately they are not the only ones, in particular the online market is a place where many dealers play games with customers since usually people buying a ring, earrings or whatever have no much knowledge about jewelry

When buying gold rings

diamond necklace or similar be also very careful, because you are focused on this outstanding piece of princess cut diamond which finally is the center of the ring the company who makes the the ring know you wont be very bullish on the gold, so they mix a low level gold together. This is  rampant in Asian countries, in particular Thailand.

A jewelry price is the precious stone and the gold

or platinum, titanium or silver. Interestingly the purest gold they sell in the Gulf States and Switzerland, actually the Gulf States including Saudi Arabia usually purchase their gold and diamonds via Switzerland and not Antwerp or US because the business in Antwerp and the US is 100% in Jewish hands.
