Diamond grading is an intricate process that involves evaluating, measuring and inspecting a stone to assess its quality. It can be affected by many factors such as the growth rate of the stone during production processes platinum vs gold lab diamond rings.
Fortunately, there are reliable laboratories that specialize in grading and certifying diamonds – including lab-grown ones. These labs include GIA, IGI, and AGSL.
IGI
The International Gemmological Institute (IGI) is the world’s foremost laboratory for diamonds and other gemstones. Utilizing cutting-edge technologies, it evaluates and grades diamonds of all shapes, sizes and origins.
IGI’s grading reports provide consumers with all the essential details about a lab grown diamonds Sydney, such as cut, colour, and clarity and carat weight. Furthermore, these reports offer useful data regarding its proportions and angles.
IGI is not as precise as GIA when it comes to diamond grading, but they’re still an excellent option if you need a reliable certificate for your gemstone. The only drawback is that their network of labs may not be as consistent as GIA’s, however.
GIA
GIA is the world’s premier diamond grading laboratory. Established in the early 1900s, they are an authority on diamond education and research.
In today’s confusing world of certification and grading systems, it can be overwhelming for consumers to select the correct one. That is why it is essential to know which ones are most reliable when purchasing lab-grown diamonds.
The Gemmological Institute of America (GIA) is a non-profit educational and research organization that created the 4 Cs of diamond grading: colour, clarity, carat weight, and cut. Their grading reports are renowned for their impartiality and accuracy and have become one of the world’s most reputable sources.
Recently, GIA revised their policy regarding lab-grown diamond grading, providing an advantage to vendors and buyers alike. This move will further grow the lab-grown market while giving buyers peace of mind when shopping for diamonds.
AGS
The American Gemmological Society (AGS) is a US-based diamond grading lab renowned for its scientific approach and research in diamond cut grading.
AGS utilizes a grading scale ranging from “I” to “FL.” It also prioritizes the quality of cuts, which sets AGS apart from GIA in that they allow more latitude when it comes to assessing performance and craftsmanship.
Colour is another critical aspect of diamond grading. Experts examine diamonds for hues such as “Z,” which indicates yellow, or “D,” which indicates colourlessness. Furthermore, they look for fluorescence – when a diamond emits light when illuminated.
When shopping for a diamond, whether natural or lab-grown, it is essential to find an established grading laboratory. Doing this will guarantee you get an accurate stone with proper certification and safeguard your investment.
AWDC
AWDC (formerly the Diamond High Council) is the official representative and champion of Belgian diamond industry interests. Headquartered in Antwerp, AWDC strives to foster a multicultural, transparent, ethical business climate within this industry.
At AWDC, diamond certification and grading systems are based on the four Cs of diamond quality: carat weight, colour, clarity, and cut. These factors are evaluated by trained experts before being sent to jewellers for verification.
These grading systems guarantee the quality of lab-grown diamonds is comparable to mined ones, taking into account factors like chemical composition and growth rate during production processes such as CVD or HPHT.
Certification and grading lab-grown diamonds is essential for consumers, as it gives them the information to make informed decisions when shopping for diamonds. Furthermore, it protects the diamond industry by guaranteeing accurate certification of these newly created gems.
In addition to the labs mentioned above, there are other organizations, such as EGL and HRD that offer diamond certification and grading services. However, it is crucial to note that not all grading labs are created equal, and some may have looser grading standards than others, which can impact the value and quality of a diamond. Therefore, it is essential to research and choose a reputable and established grading laboratory when purchasing a diamond, whether natural or lab-grown.
Conclusion
Moreover, technological advancements are also shaping the future of diamond grading and certification. For instance, block chain technology is being explored as a means to create an unalterable and transparent ledger of a diamond’s history and certification. This would provide buyers with greater confidence and trust in the diamond industry, ensuring that they are investing in an authentic, certified, and ethically-sourced diamond. Ultimately, the continued development and integration of new technologies will help shape the future of diamond grading and certification systems, providing greater transparency, accuracy, and consumer protection.
