Post By admin Diamond

Diamond have various colors, some of the very precious and very expensive Diamonds have a color like Pink (pink), blue, even yellow. But in white diamonds, the presence of yellow will reduce the price of diamonds. The less color there is in the white Diamond stone, then the truer color will reflect, and thus the greater its value.

A pure and structurally perfect diamond, colorless transparent, or color. However, in reality almost no natural diamond-sized gem is absolutely perfect. The color of the diamond may be affected by chemical impurities and / or structural defects in the crystal lattice. Depends on the color and intensity of the color of the diamond, diamond color can either reduce or increase the value. As an example, most white diamonds are discounted in price when a more yellow hue is detected, while intense pink or diamond blue (like Hope Diamond) can be dramatically more valuable. Of all colored diamonds, the rarest red diamond.

The majority of mined diamonds come in various shades of yellow or pale brown which is called the normal color range. Diamonds that are intense yellow or brown, or other color called luxury color diamond. Very high purity diamonds are completely colorless, and looks bright white. The degree to which a diamond exhibits the color of a stone Diamond is one of the four value factors by which a diamond is valued.

Diamond color levels

Colorless (colorless)
Although there is a color difference between D, E, and F diamonds, they can be detected only with a gemologist on a side by side comparison, and rarely by the untrained eye.
Diamond D, F can only be arranged in white gold / platinum. Yellow gold reflects color, negate the colored diamond effect.

Near Colorless (Slightly colored)
While containing traces of color, diamond G, J is suitable for platinum or white gold settings, which will usually betray the color marks on the diamond.
Because diamond I, J is more general than higher values, they tend to be of great value. A diamond I, J can be sold for half the price of diamond D. In the range of G, J, prices tend to increase 10-20% between each grade diamond.

Faint Color (there is color)
Starting with K . diamonds, color (usually yellow) more easily detected by the naked eye.
Set in yellow gold, This warm colored diamond is attractive to some people, and incredible value. Others will feel that they have too many colors. Because the colors are clear, a K diamond is often half the price of a G berlian diamond.

Very Light Color (Very Colorful)
Diamonds in the N . color range, R has a yellow or brown color easy to see, but much cheaper than the higher value.
Lumera does not carry diamonds in this color range due to lack of demand. If you want diamonds in this range, ask price quoteusing custom diamond search.

Light Color (Bright colors)
For almost all customers, SZ diamonds have too many colors for white diamonds.

Sapphire Stone Kashmir

Even, silk inclusions can increase the value of the stone by giving it a velvety feel like sapphire Kashmir valuable. Although commercial quality blue sapphires are now reliable, blue rough quality is always rare and expensive. Blue sapphires weighing one carat or more are usually not cut to calibrated sizes or standard shapes. Vice versa, each stone is shaped to maximize the yield of coarse crystals. This means a perfect match is hard to find in larger sizes.

In blue sapphire, the cut can affect the color in surprising ways. Sapphire is a dichroic stone, which means the color varies depending on the angle from which the stone is viewed. Seen in one direction, mostly blue-blue to blue-violet-blue sapphires, from the other direction, greenish blue. Skilled cutters will aim their stone while cutting the most desired blue color until a purple-blue color shows through the finished gem.

Blue sapphires are found in a number of locations around the world including Kashmir, Myanmar, Sri Lanka, Madagascar, Thailand, Australia, Tanzania, and the state of Montana in the United States.

Red color on Ruby Stone mainly due to chromium (am) with Hexagonal crystal system. The best Ruby is blood red (am) and Crystals from Burma (Myanmar). and Crystals originating from Myanmar known as Burmese Ruby. and Crystals originating from Myanmar known as Burmese Ruby, and Crystals originating from Myanmar known as Burmese Ruby.

Ruby Color

Ruby is the most precious and valuable of all colored gemstones. Rubies have had something of importance in many cultures for thousands of years. Ruby is characterized by dynamic shades of red, very good red (aspect reflects light almost like a mirror), and violence (difficult to start and therefore tough). Very large best quality ruby ​​gemstones are very rare to find.

The price of rubies is mainly determined by the color. The brightest and most valuable red color can cost a lot more than other rubies of the same quality. After color, next is clarity: A clear stone indicates a high price.

Batu Ruby Pigeon Blood (Pigeon blood) from Burma

historically, term “pigeon blood” describes a ruby ​​red to slightly purplish or pink color with a soft red fluorescence, glowing. Traditional descriptions like these are useful for evoking images and depicting colors among professionals. But they can be misinterpreted when used to describe the true color of a ruby.

Real Sapphire (Natural)

Types of Natural Sapphires derived from certain igneous or metamorphic geological environments are usually treated to improve their color or clarity. The most common processes involve heat treatment to enhance color. Synthetic Sapphires have been in production for over a century, mostly by melting, quickly, or hydrothermal solution method. All these materials are widely found in the jewelry trade.

The most important instrument in distinguishing real Sapphires (Natural) and synthetic sapphires using a binocular microscope. Information gathered from brief microscopic observations of unknown Sapphire gems is essential for accurate identification and is known only to gemologists themselves.. There is no better reference for understanding the microscopic features of corundum than a three-volume photoatlas of inclusions in a gemstone.

Diamond (Batu Intan)

Post By admin Diamond

Diamond or also called Batu Intan (Diamond) is a type of Natural Carbon Crystal stone. “In mineralogy” Diamonds are metastable carbon allotropes, where the carbon atoms are arranged in a variation of the cubic crystal structure. Diamond is renowned as a material with superlative physical qualities, most of which comes from the strong covalent bonds between the atoms. In particular, Diamond is the hardest type of precious stone that has value 10 from Scale 10 Mohs and thermal conductivity of various bulk materials.

The formation of diamonds at high temperatures and pressures that occur in the Earth's mantle around 100 miles down.
Most of the diamonds that have been found were sent to the Earth's surface by deep-source volcanic eruptions. These eruptions begin in the mantle and travel on them until they tear pieces of the rock mantle and deliver them to the earth's surface without melting. These blocks of the mantle are known as xenoliths. They contain diamonds that form at the high temperature and pressure conditions of the mantle.

People get Diamonds from diamond mining (Diamond) containing xenoliths or mining soil and sediment that forms as weathered diamond-bearing rock. Some diamonds are thought to have formed under high pressure temperature conditions from subduction zones or asteroid impact sites. Some were sent to earth in meteorites. No commercial diamond mines have been developed on deposits with these origins.

Martapura Diamonds

Diamond is one of the most expensive gemstones because the stone is very rare and has a sparkle or can emit light. There are also diamonds that are colored like Blue Diamonds (Blue Diamond), Yellow Diamonds (Yellow Diamond) and Black Diamond (Black Diamond). Diamond Mine (Batu Intan) found in Africa. In Indonesia also has a diamond mine (Diamond) that is in Martapura (Borneo). Diamonds symbolize purity, glory, prosperity and power for the wearer.

Diamonds are one of the most valuable tertiary items that a person can own. If you keep it as an investment in the future, value will continue to rise. Understood, diamonds are rare and expensive items because they are not easy to mine. No wonder potential investors need to know more about diamonds to get the best quality as an investment.
