Diamond FAQ
Diamond – What is it?
A diamond is a crystal made up totally of carbon atoms. They are arranged in an isometric, or cubic, matrix. A cubic crystal planning is where the crystal basically increase in ouward direction at the same rate in all directions during its growing; the perfect outcome, when the crystal forms without any snooping, is a pure and perfectly formed octahedral shape.
However, most diamond quartz encounter varying heat or pressure, other basics, or even additional diamond mineral during their growth, and this can revise their form slightly. The resulting form and features of the crystal, once it occur from the earth, help to determine what form, color and precision the polished gem will have.
The combination of diamond’s molecular composition and its crystal structure is what pressure it so rare and yield it all the virtues that we think of when we think of a diamond.
Consider this: The graphite that you usually find in pencils is also made of pure carbon structure, but because the carbon atoms are organized differently, the end result is a soft gray-dim material that is very unlike hard, dull diamond. And iron feldspar (famous more commonly as fool’s gold) grows in an isometric array, but because it is not made of pure carbon, it also lacks the amazing what it takes of diamond.
The irreplaceable physiognomy of diamond go far beyond what you can see. Besides their upper luster and dispersal, diamond stones are the hardest usual matter on earth.
Diamond hardness a 10 on the Mohs scale of hardness, which means that it is tremendously hardy to cuts; it is several times problematical than the next-hardest element, corundum, which is more commonly recognized as ruby and sapphire.
Diamonds are also very tough, meaning that they do not easily break, chip or crack. And even more remarkably, they are extremely sturdy to heat and chemicals: it would take a temperature of at least 720° Celsius in air, or 850° Celsius in a vacuum space, to burn a diamond; and sulphuric and hydrochloric acids, which are proficient of completely dissolving the skin and framework of a person, have no effect at all on diamonds (in fact, these harsh chemicals are actually used to clean the oil and dust off polished diamonds after they have been cut).
Where do diamond stones come from?
Diamonds are made up of pure carbon structure atoms that exist deep in the earth, exposed to severe heat and pressure over billions of years. Over time, this pressure builds up and pushes the diamonds and rocks up toward the surface in a volcanic-like detonation. The burst creates a very deep, wide hole entitled a “pipe” into which most of the diamond stones settle; these buildup of diamond stones are acknowledged as first layer. Other diamonds are washed away by river or corrosion, and often settle into the coastal waters. These accumulation occur in many places around the globe; however, the largest commercial deposits exist in Angola, Australia, Botswana, Namibia, South Africa, Russia and Zaire, which produce 80% of the globe’s diamonds.
When you visit a diamond seller’s, you may not think diamond stones are especially rare. But study this: 250 tons (500,000 pounds) of ore must be extracted and crushed to produce just one carat of rough diamond. Since a rough diamond typically loses 40% to 60% of its weight when cut, that means that all these efforts are vital to produce just one of the .50 carat polished diamond stones you find in the store’s exhibition stall. When you also weigh up the fact that only around one part of all rough diamonds are actually apposite for gem hurtful, you can begin to be thankful for the rarity and uniqueness of each diamond.
A speedy, fun fact: The elementary diamond layer were brought to the outward of the earth almost 2.5 modicum ages ago. The most hot accumulation are nearly 50 million ages old. Your diamond is a actually unique case of history.
How is a diamond cut?
A anew mined rough diamond looks more like a portion of crystal washed up on the beach than like the polished gems sold in diamonds stores. Bringing out their prettiness requires the talent and art of a accomplished diamond editor in chief.
While extremely precise, computerized equipment is now used in some parts of the caustic process for some diamonds, most of the work is motionless impersonate by hand shooting up exacting and thorough practice passed down over the generations.
As a former step, link or sawing is often used to solitary the unusual rough into reduced, more workable shards that will each finally become an individual polished gem. Next, bruting grinds away the edges, if the shape form (for case in point, courage, oval or round) for the gem. Faceting is then done in two emergency exit: during obstructive, the table, culet, bezel and rotunda main aspect are cut; afterward, the star, superior girdle and worse girdle feature are other.
Once the entirely faceted diamond has been look at and better-quality, it is barbecued in hydrochloric and sulfuric acid substances to get rid of dust and oil. The diamond is then considered a washed-up, polished gem.

What is an “Ideal Cut”?
The “Ideal Cut” is a cut based on a identifiable set of scope for a round brilliant diamond proposed by gem managing editor Marcel Tolkowsky in 1919. While Tolkowsky’s special scheme these days only one certain combination of size for coin the best balance of radiance and scattering, today the American Gemological Society recognizes any diamond falling within a slight scale of magnitude and finish value as actuality an “Ideal Cut” (also so-called an “AGS 0″ or “AGS triple zero”).

How does a diamond get from the excavation to the stores?
Finding the rough diamond stones is only the fundamental step. Once diamonds have been extracted and processed out of the ‘burden‘ (that is, the kimberlite rocks in which they are imbedded), the rough crystals are in the bag and categorized according to their size, tint, shape and other characteristics. At this item, a diamond can shadow one of two means.
The most common course is through the channels of DeBeers’ Central Selling Organization (CSO). Many people are familiar with DeBeers mainly because of their advertisements and commercials and because of the prominent byword that they coined in the timely half of the 20th century: “A Diamond is Forever.”
While DeBeers’ marketplace power has drop to some degree over the last few years, they tranquil circuit breaker the majority of the biosphere’s diamond manufacture (an estimated 30% to 40% of every twelve months diamond construction). The winning arm of the CSO not only buys diamond stones from delegate source around the creation; it also finances taking out skill for management which do not have the means to mine their own buildup. Most of what is bad deal through the CSO is sent to London to be offered to consumer through DeBeers presentation arm, the Diamond Trading Corporation (DTC).
The DTC clutch ten week-long peddling sessions termed ‘wonders‘ each year. These places of interest are by invitation only, and only a some of diamond builder from around the world (titled ‘sightholders‘) are allowed to think about. These sightholders may pick to cut the rough diamonds they buy themselves, or they may wish to sell some of the rough diamond stones to slighter producer.
These lesser industrialist cut the rough diamonds and sell the polished gems whichever to jewelry maker (who set the diamond stones into finished bits of jewelry and then sell the diamond to diamonds retailers), or to diamond wholesalers (who then, in turn, sell the diamonds to diamond retailers).
In the less common track from mine to fair, some independent mineworker elect not to sell their mine creation to the DeBeers league. Instead, they compromise afresh mined diamond stones directly to additional ecosphere customer. These bargain hunter, in turn, may opt to cut and sell the diamonds themselves, or pass the diamond stones along within the commerce in a modus similar to that described above your head.

Is a diamond a good investing?
The rejoinder be suspended on whether you are investing in the diamond itself, or in what a diamond be a symbol of.
Diamond prices have been increasingly increasing for the past 20 years, and diamond stones tend to hold their rate. Given this, it is enormously doubtful that diamonds will ever completely lose their cost, in spitefulness of how the market may change in the future. However, no one can predict, with unadulterated cast-iron certainty, which way the shop will swing and, in customary, we do not recommend ordering up high-worth diamond stones as a main part of a financial/stepping down plan.
On the other hand, if you are looking for a informant of attraction and a emblem of ever and a day and eternal love, there are few objects you can choose that will better a diamond’s precision. Diamonds have angry man’s passions since the chief moment at which they were naked, and their power over our sensation and wish has only grown since then. As a timeless and stunning gift to yourself or as an device of your commitment to any more, a diamond is an first-rate venture.
What is the disagreement between a “certified diamond” and a “non-certified diamond”?
There is no physical differentiation between a diamond that is certified and one that is not. A certificate does not change the nature of a diamond in any way. The difference between a certified and an uncertified diamond is that, with the certified diamond, you have tangible, permitted self-possession as to the precise nature and quality of the diamond you are purchasing.
A certified diamond comes with a diamond grading report guaranteed by an accredited gem lab. This description nail down the punter that the diamond is independently predictable as possessing all the facts itemized by that statement. All the diamonds featured in the Diamond Store on our site are certified by either one GIA or AGS. When you buy a certified diamond, you are getting a diamond with loveliness and noble. Try our limp diamond stones database to find GIA certified diamonds.
On the additional hand, an uncertified diamond has is not accompanied by a diamond grading statement, and so its worth is based only on the word of the seller.
An uncertified diamond is not certainly a bad diamond; certainly, it can be as gorgeous as a certified diamond. However, we incite our customers to buy certified diamonds for the resulting reasons:
Shopping for certified diamond stones allows you to make choice about your selections, and to comparison shop. You can compare one diamond with a specific mass and value with other diamonds of similar weight and quality to determine which is the better charge. With uncertified diamond stones, it is difficult to determine whether the quality measurement of one jeweler will be as stringent and exact as the judgments of additional jewelers; that is, not all jewelers may consent about the worth of an uncertified diamond.
A diamond grading description adds price to a diamond. The value estimation made by independent labs, such as GIA or AGS, are important worldwide. These value appraisal are used by appraisers to determine the protection or replacement worth of your diamond. If you buying an uncertified diamond, there is no guarantee that the appraiser will review your diamond at the same level at which the jeweler who sold it to you did. A rapid note on how reports from various independent labs compare with one another: GIA and AGS are well-thought-out the business leaders, and the ending word on gem worth, among diamond wholesaler worldwide. While ample of additional independent labs exist, some are a bit lax in their taxation of diamond quality and do not command the same respect for consistency and value of grading that GIA and AGS do. For this right mind, if you are in the souk for a diamond, make an labor to buy only GIA- or AGS-categorized diamonds.
A diamond grading report adds an increased comfort-level to your purchase. Because the worth of your obtaining has been independently confirmed, you can feel assured that you have made a wise buy and that you have received correctly what you have paid for.
Is it safe to receive a diamond in the mail?
It is safe if the diamond jeweler uses covered hauler (e.g., FedEx and UPS) to ship its packages and all delivery are insured for the full value of their contents.
Before buying a diamond online, find out what the store’s custom is in case of lost shipments. A qualified diamond jeweler must have no objection to on condition that both a replacement or a repayment.
