Diamond Shopping: What You Need To Know About Diamond Carat Weight and Color

August 18th, 2010

If your search for the perfect diamond has begun, you have no doubt spent hours of confusion navigating the alphabet soup of VVS-2, SI-1 GH, IF, DE, the four c’s and all the other myriad combinations of letters and numbers that have a huge impact on a diamonds price. Here are some fascinating diamond facts as well as information on the importance of diamond carat weight and color and how they affect diamond prices.

Diamond mining originated in India. Prior to the discovery of diamonds in Africa in 1867, these gems were extraordinarily rare available only to royalty and the upper classes. Diamonds are formed under intense heat and pressure deep within the earth in a specific type of volcanic pipe called kimberlite. Volcanic eruptions forced diamonds out of their dark hiding places and many diamonds have been recovered from streams and river beds. These are called alluvial diamonds. Other diamonds settled back into the kimberlite pipes. Recovering diamonds from kimberlite involves mining.

One of the most important factors that affect the price of a diamond is the carat weight. Carat is a unit of measure that derives from the carob bean, which is extremely uniform in weight. Early diamond traders in the Mid-East used the carob bean as the standard unit of measure for determining a diamond’s weight. Larger diamonds are rarer and command a higher price per carat. A good quality diamond of a half-carat may cost $1,000.00-$1,500.00 while a full one carat may be closer to $5,000.00 to $6,000.00. A good quality two-carat diamond will fall into the $16,000.00-$20,000.00 range.

Color is another important consideration when diamond shopping. Aside from irradiated colored diamonds, most color in diamonds is caused by elements and gasses present when the diamonds are formed. The closer to colorless the diamond is, the more expensive it will be. A fine quality one-carat near colorless diamond may cost upwards of $7,000.00, while a true colorless diamond of the same weight and clarity will be well over $10,000.00.Keep in mind that color in diamonds is difficult to detect. Taking two sheets of white paper from different sources and noticing the subtle contrast between them is a good way to familiarize one’s self with how faint the gradations of diamond colors can be. Tiny differences will have a substantial impact on price.

Understanding how carat weight and color affect diamond prices will help you determine your diamond buying budget. Once you decide on the criteria most important to you, you will have an informed idea of what to look for in making your engagement ring dreams come true.

Diamonds: Show your True Color

December 29th, 2009

Just like with us humans, diamonds have their unique races and this is shown through their colors.

Diamonds though sometimes it may look the same with its own kind still have this tinge of difference with each other.

Its color is the main reason of this difference.

During the year 1999 Color typing was made known through Gran Full Spectrum Colorimeter DC2000fs (Gem Instruments).

This instrument has been precise in actually determining the difference of one diamond with its other own kind.

Truly not everything can be seen by the eye.

he next thing we’ll know scientists may discover on how to categorize colors of the diamond.

The instrument may also be reliable and significant for you to determine if what you are buying is true genuine.

Now nothing is impossible since we are now living in an advance world. Through technology and science we can now live in a more complex but convenient world.

Only that people must learn how to use these modern technology in a proper way. That this modernization will not lead to our own destruction.

It’s a great break for the lab to discover the Gran Full Spectrum Colorimeter. In this manner scams will reduced. Spreading of fake diamonds will now be on hold.

There are still lot of things to be done to have more improvements for this instrument, which we must await for. An exciting discovery that we should be aware of.

Now the latest is DC3000 which will arrive hopefully on October 5. The edge of this new development is that it will no longer require manual dark field calibration and it has improved platform makes it more convenient. What’s more? well this DC3000 will be reading according to the GIA standards.

You see we are in such a fast phase time indeed. So we shouldn’t be left out. Always keep yourself updated for new discoveries.

Learn the 4 C’s of Diamonds: Cut, Color, Clarity and Carat Weight

November 25th, 2009

Click the Certificate link below to learn all about A.G.S – American Gem Society or the G.I.A – Gemological Institute America.

CUT…A diamond’s cut is not only about its shape, but how effectively the stone can return light back to the viewer’s eye. A well-cut diamond will appear very brilliant and fiery; while more poorly cut stones can appear dark and lifeless, regardless of color or clarity.

Color…When shopping for a diamond, it is generally preferred to have the least amount of color possible. Diamond color is divided into five broad categories:

Colorless: Diamonds within the colorless range are the most rare and valuable of all the colors. color stones display virtually no color, whereas colored diamonds will display a nearly undetected amount of color when viewed face down by a gemologist.

Near Colorless: Diamonds within the near colorless range appear colorless in the face up position, but do display a slight amount of color when viewed face down against a perfectly white background. This trace amount of color will be undetectable to an untrained eye once the diamond has been mounted. Near colorless diamonds offer a tremendous value for the money.

Understanding Fluorescence – How does it effect a diamond?

Some diamonds can display a visible light called fluorescence when exposed to an ultraviolet light source. This fluorescence will be measured as inert, faint, medium or strong. Blue fluorescence is most common, however diamonds can also fluoresce white, yellow, and orange (among other colors). Fluorescence usually has no effect on a diamonds appearance in regular light conditions. Strong blue fluorescence can make a yellow colored diamond appear more white, but in rare cases can cause a stone to appear milky or oily. This milky or oily effect is called an “over blue” and only applies to a small number of “strong” and “very strong” fluorescent stones.

Which Color should you Choose?

Most people find it very difficult (if not impossible) to tell the difference from one color grade to another. The difference in price, however, can be significant.However, you can find a tremendous value while still achieving a “colorless” look. Shopping on a budget or trying to maximize the size of your stone? If so then “J” diamonds are most affordable and still near colorless. You may also want to consider choosing a diamond with medium or strong fluorescence. Since these diamonds are discounted slightly in price you can often afford a higher color stone without paying the premium.

Angola

In 1998, the United Nations (UN) placed Angola under sanctions forbidding countries from buying diamonds from them. This was the first resolution of the UN which specifically mentioned diamonds in the context of funding war. Reports estimated that as much as 20% of total production in the 1990s were being sold for illicit purposes, and 15% were specifically conflict in nature.By 1999, the illicit diamond trade was estimated by the World Diamond Council to have been reduced to 3.06% of the world’s diamond production.The World Diamond Council reported that by 2004 this percentage had fallen to approximately 1%.

Angola is a former colony of Portugal and gained independence in 1975. Although independent, the country saw civil war between the Popular Movement for the Liberation of Angola (PMLA) faction, and the National Union for the Total Independence of Angola (UNITA) faction. During this war, diamonds were traded by rebel groups to fund their war. The UN recognized the role that diamonds played in funding the UNITA rebels, and in 1998 banned countries from buying diamonds from Angola. Today Angola’s civil war has ended and the country is now a legitimate part of the diamond trade.

Sierra Leone

In July 1999, following over eight years of civil conflict, negotiations between the Government of Sierra Leone and the Revolutionary United Front led to the signing of the Lome Peace Agreement under which the parties agreed to the cessation of hostilities, disarmament of all combatants and the formation of a government of national unity. The United Nations and the Economic Community of West African States (ECOWAS) helped facilitate the negotiations. In resolution 1270 of October 22, 1999, the Security Council established the United Nations Mission in Sierra Leone (UNAMSIL) to help create the conditions in which the parties could implement the Agreement. Subsequently, the number of personnel were increased and tasks to be carried out by UNAMSIL adjusted by the Council in resolutions 1289 of February 8, 2000 and 1299 of May 19, 2000, making UNAMSIL the second largest peacekeeping force currently deployed by the United Nations (the largest such contingent is in the Congo.

Following international concern at the role played by the illicit diamond trade in fueling conflict in Sierra Leone, the Security Council adopted resolution 1306 on July 5, 2000 imposing a ban on the direct or indirect import of rough diamonds from Sierra Leone not controlled by the Government of Sierra Leone through a Certificate of Origin regime. An arms embargo and selective travel ban on non-governmental forces were already in effect under resolution 1171 of June 5, 1998.

On July 31, 2000 and August 1, 2000, Ambassador Anwarul Karim Chowdhury, Chairman of the Security Council Committee established pursuant to resolution 1132 (1997) concerning Sierra Leone, presided over the first ever exploratory public hearing by the Security Council in New York. The hearing was attended by representatives of interested Member States, regional organizations, non-governmental organizations, the diamond industry and other relevant experts. The hearing exposed the link between the trade in illicit Sierra Leone diamonds and trade in arms and related material. The ways and means for developing a sustainable and well-regulated diamond industry in Sierra Leone were also discussed.

As called for by resolution 1306 of July 5, 2000, the Secretary-General, on August 2, 2000, established a Panel of Experts, to collect information on possible violations of the arms embargo and the link between trade in diamonds and trade in arms and related material, consider the adequacy of air traffic control systems in the West African region for the purpose of detecting flights suspected of contravening the arms embargo, and report to the Council with observations and recommendations on ways of strengthening the arms and diamonds embargoes no later than October 3, 2000. The Chairman of the Panel was Martin Chungong Ayafor (Cameroon). The other members were Atabou Bodian (Senegal), Johan Peleman (Belgium), Harjit Singh Sandhu (India) and Ian Smillie (Canada). The Panel submitted its report to the Security Council on December 19, 2000. On January 25, 2001 the Security Council, at its 4264th meeting, considered the report of the panel of experts.

Diamond revenues in Sierra Leone have increased more than tenfold since the end of the conflict, from $10 million in 2000 to about $130 million in 2004,although from 1989 to 2003 Liberia was engaged in a civil war. In 2000, the UN accused Liberian president Charles G. Taylor of supporting the RUF insurgency in Sierra Leone with weapons and training in exchange for diamonds. In 2001 the UN applied sanctions on the Liberian diamond trade. In August 2003 Taylor stepped down as president, and after being exiled to Nigeria, now faces trial in the Hague. On July 21, 2006 he pleaded not guilty of crimes against humanity and war crimes.

Liberia today is at peace and is attempting to construct a legitimate diamond mining industry. The UN has lifted sanctions and Liberia is now a member of the Kimberley process.
