How Can You Know if a R Is Natural or Lab Created
How To Tell If a Diamond Is Real? Your Guide To Synthetic vs Natural Diamonds
Westworld, the new HBO serial, is seizing the attending of today'southward viewers with technologically advanced hosts that expect and human action similar real people, but are actually lab created fakes. The boundaries of what is real vs what is faux are being tested in very new and cutting-edge means.
Similarly, within the diamond world, the aforementioned question exists: Is this a real diamond or a technology advanced imitation?
A real diamond, as defined past the Oxford English Dictionary, is: a precious stone consisting of a clear and colorless crystalline course of pure carbon, the hardest naturally occurring substance.
Many diamond-like stones are being sold in the marketplace, these stones may be look-alikes or are being man-fabricated, lab created and manufactured, and it gets harder and harder to know what is a existent diamond. How do you know if what you are seeing is considered a real diamond or a fake diamond engineered to look like a real diamond?
Worthy wanted to acquire the truthful facts and understand if it was possible for an individual to identify a real naturally occurring diamond vs. a "fake" diamond. Is it visible to the naked heart to see the deviation yourself?
The Gemological Institute of America (GIA), the leading source for identifying diamonds, helps answers our questions and gives us sound advice forth the way.
Worthy Q&A with GIA:
1. WORTHY: Are synthetic diamonds considered fake?
GIA: In gemological terms, a diamond is a diamond whether it was mined from the ground or grown in a laboratory. Natural diamonds and synthetic diamonds are chemically, optically and physically the same, and are made up of a unmarried chemical element: carbon. Natural diamonds, considered by many every bit Earth's little treasures, are formed under tremendous estrus and pressure deep inside the World over millions and maybe billions of years. Constructed diamonds (likewise known as lab-grown and human being-made diamonds) are produced in a laboratory over the course of days or weeks.
2. WORTHY: Can y'all tell the difference betwixt a homo-made, lab grown diamond and a existent natural diamond?
GIA: GIA can identify all known constructed diamonds on the market today. The Institute has been researching constructed diamonds since they were get-go created more than 60 years ago.
Every diamond submitted to GIA for grading is screened to determine if information technology is natural or possibly synthetic or treated. Post-obit the initial screening, any diamond that is flagged every bit potentially synthetic or treated undergoes rigorous examination to confirm if it is natural or synthetic, and what treatments – if any – have been applied.
Since at that place's no mode for a consumer to encounter the differences between a natural and synthetic diamond, it's important to take a diamond grading report from an independent laboratory like GIA to ensure they are getting the gem they expect.
three. WORTHY: What are diamond simulants and how are they different than natural diamond?
GIA: In the jewelry merchandise, diamond "look-a-likes" are known equally simulants or imitations, and can be either natural or manmade. Diamond simulants are different materials from natural and synthetic diamond. Because they differ in their chemistry and atomic structure they take quite different optical and concrete properties. These differences let them to be detected by a competent gemologist relatively easily. A few examples of diamond simulants are:
- Synthetic cubic zirconia (CZ) – early diamond simulants have been almost entirely replaced in the past three decades past colorless CZ. Information technology is made by a process chosen skull melting. As the textile melts, the outer portion is kept absurd to form a solid crust which then contains the melt. CZ tin can be produced in nearly any color, and in darker hues, it is a convincing alternative for gems in purples, greens and other dark tones including blackness. Prevalence: common.
- Synthetic moissanite – colorless constructed moissanite was introduced in the tardily 1990s as a diamond simulant. It is closer to diamond in overall appearance than any previous diamond imitation, simply now it is about often sold as a gem in its own right. Prevalence: occasional.
You tin can acquire more virtually diamond and other gem simulants on GIA's website.
four. WORTHY: If my colorless stone can scratch glass, does that hateful I have a existent diamond? Does a scratch exam on glass work?
GIA: There's no shortage of communication on how to tell if a diamond is real, even so much of this information is incorrect, and some methods can even damage your gem. The most reliable way to authenticate your diamond is to consult a trained gemologist or send information technology to an independent gemological laboratory for analysis. A lab, like GIA, will have the expertise and instrumentation to distinguish between natural diamonds, diamond simulants (or imitations), and synthetic diamonds, and to detect diamond treatments.
As mentioned before, constructed diamonds are man-made and accept the same physical properties as natural diamonds. Synthetic diamonds are diamonds. You cannot spot a synthetic diamond by looking at it through a loupe. The simply way to tell is by laboratory testing.
If your diamond already has a GIA diamond report, like a GIA Diamond Grading Report or GIA Diamond Dossier®, yous know you have a natural diamond. The reports not only place the diamond, they too provide an unbiased cess of your diamond's quality according to the 4Cs: colour, clarity, cut and carat weight. The reports too disclose whatever treatments the diamond may have undergone to improve its colour appearance or clarity.
5. WORTHY: How hard are diamonds? Are diamond simulants every bit hard every bit existent diamonds?
GIA: Diamonds are the hardest material on earth, 58 times harder than anything else in nature. Simply a diamond tin scratch a diamond.
vi. WORTHY: If my diamond is chipped, does that mean it'due south not really a diamond? Are diamonds unbreakable?
GIA: Any rock, including a diamond, will intermission if it's hit hard enough in the correct place. Toughness is a measure of how well a jewel can survive an bear upon and resist breaking, chipping or cracking. Diamonds are tougher in the directions where the atoms are bonded tightly together, less tough where they're not so tightly bonded.
The weakest directions are the ones where the atoms are farthest autonomously. It's easier to suspension a diamond in those directions, which are chosen cleavage directions. A cutter tin cleave a diamond by hitting information technology sharply in the cleavage management. But even after cut, a hard accident can withal carve a diamond. This can happen during the setting process, or even when information technology'due south being worn.
seven. WORTHY: Is clarity described differently on natural diamond grading reports and constructed diamond grading reports?
GIA: A diamond's relative lack of "imperfections," known as "clarity characteristics," determine the gem's clarity. Clarity characteristics located on the surface of the diamond are called blemishes. Those within the diamond are called inclusions. The diamond'due south clarity is adamant by the number of inclusions, the size of the inclusion in relation to the size of the diamond, location, relief (how piece of cake it is to meet information technology) and nature (the blazon of feature and its inherent upshot on the diamond). All of these factors relate to each other when determining a clarity course.
In natural diamonds, clarity is measured using a scale of 11 grades that range from Flawless (no inclusions or blemishes are visible to a skilled diamond grader using 10× magnification) to Included (inclusions are obvious without magnification and may touch on a diamond'south transparency, luminescence or immovability).
GIA presents clarity data for synthetic diamonds differently. The GIA Synthetic Clarity Scale uses descriptions rather than grades for synthetic diamonds in the Very, Very Slightly Included to Included ranges.
8. WORTHY: Does a diamond reflect calorie-free differently than a diamond simulant similar CZ or Moissanite™? Can the human center run across this?
GIA: While some consumers may exist able to distinguish a diamond simulant from a diamond with the naked heart just by the way information technology reflects light, information technology's important to always work with a professional person jeweler to determine your gem's authenticity.
The style a diamond reflects calorie-free is ane of the attributes that many consumers cherish about the stone. If you've always wondered why your diamond looks different in sunlight versus candlelight or daylight versus role lights, it's because the cut of your diamond responds differently depending on the light and the environment you are in. How – and where – you look at your diamond can greatly change its appearance.
When it comes to round vivid cut diamonds, the most popular shape of diamond for engagement rings today, look for brightness (often called luminescence) – the effect of all the diamond's internal and external reflections of white light. This is best observed under diffused lighting. Well-cut diamonds are brighter than poorly fashioned ones, even if they're of equivalent size, color and clarity. Poor polish and symmetry causes brightness and fire to diminish.
- Look for red, blue, yellowish or orange flashes as you rock and tilt information technology under store spotlights. This is called fire. It'due south caused when white light traveling through the diamond is dispersed into its rainbow of spectral colors.
- Look for sparkle – the spots of light that flash when the diamond, you or the low-cal source moves.
- Look at the patterns of bright and night areas that outcome from a diamond's internal and external reflections. You should come across plenty dissimilarity between the vivid and dark areas to give the pattern a crisp, sharp look, only no larger distracting dark areas.
- Wait for scintillation – a combination of sparkle and pattern. In an attractive diamond, the reflections should appear fairly even and counterbalanced in size.
9. WORTHY: Are color and clarity enhanced diamonds considered real diamonds?
GIA: Yes. A handling is any procedure used to improve the apparent color and/or clarity of a diamond. Treatments (oftentimes chosen enhancements) can be permanent (like HPHT process) or unstable (like fracture filling). As part of its grading process, GIA tests all diamonds for treatments. If a diamond is treated, the handling is disclosed on the grading report.
"Clarity enhanced" is a wide term used to describe a diamond that has had its clarity contradistinct by the use of laser drilling or fracture filling.
- Laser drilling: A clarity enhancement procedure used to meliorate the appearance of a diamond that contains nighttime inclusions. A pigsty is drilled into the diamond with a laser to reach the inclusion. If the included material is non vaporized by the laser itself, it is dissolved or bleached with acid. This is a permanent treatment and laser drill holes affect the clarity grade. GIA will issue grading reports on laser drilled diamonds providing at that place is no added filler. This handling should ever be disclosed.
- Fracture filling: A clarity enhancement process that uses a drinking glass-like substance to fill up surface-reaching inclusions, such as feathers or laser drill holes, to brand them less visible and ameliorate the jewel's appearance. This treatment is not permanent equally the filling tin can be reversed by sure types of jewelry repair. GIA will non issue grading reports on filled stones, but identification reports. This treatment should always exist disclosed.
A treatment known every bit HPHT (High Force per unit area/High Temperature tin can change the color of some diamonds.
- HPHT Treatment: A colour enhancement process used to alter, enhance, or remove colour in diamonds. HPHT can change some brownish diamonds colorless or transforms these brownish stones into other colors similar yellowish, greenish yellowish, or dark-green. This process is also associated with treated pink, blue, and orangish-yellow diamonds. HPHT is considered a permanent process and should ever be disclosed.
"The enhanced diamond resell market" as stated past Roy Albers, Chief Gemologist Worthy, "is dissimilar from the natural diamond market place and has its unique set of buyers and pricing. Worthy, working with GIA will exist able to place and will disclose all treatments to its clients, and then the sellers know exactly the diamond they take."
