What Is Diamond Certification?
What Is Diamond Certification?
A diamond certificate, also known as a diamond report, is issued by an accredited independent gemological laboratory. In addition to the loose diamond’s carat weight and measurements, a diamond certificate includes grades for the diamond’s cut, clarity, and color. You’ll also find information about the diamond’s polish, symmetry, and fluorescence.
Whether you purchase a loose natural diamond or a loose lab-grown diamond, you can feel confident knowing your certification comes from a reputable and trusted source.
 
 
Why Is Diamond Certification Important?
Why Is Diamond Certification Important?
Since 1929, Shane Co. has been in the diamond business. Transparency with our customers has always been our priority. If your loose diamond is certified, obtaining a copy of your diamond report is important for a number of reasons, including:
  • Confirming the type of diamond, whether it’s a natural diamond or a lab-grown diamond
  • Confirming your diamond’s quality
  • Verifying your ownership of the diamond
  • Verifying information about the diamond if you’re looking to insure it
 
 
Who Certifies Shane Co.’s Diamonds?
Who Certifies Shane Co.’s Diamonds?
Shane Co.’s loose natural diamonds and loose lab-grown diamonds come certified and individually verified by an accredited independent laboratory.
Our loose natural diamonds are graded, certified, and inscribed or identified through plot by the Gemological Institute of America (GIA) or Gemological Science International (GSI), both accredited and leading laboratories for natural diamonds. A small portion of our loose natural diamonds are Shane Co. Certified. That means we have used our internal lab to evaluate the diamond. Our standards closely align with those used by the GIA.
Our loose lab-grown diamonds are graded, certified, and inscribed by the International Gemological Institute (IGI), the leading accredited certification laboratory for lab-grown diamonds. Each loose lab-grown diamond is inscribed with both its IGI number and “Shane Co. Lab-Grown.” We allow customers to loupe and verify these inscriptions.
 
 
What Does It Mean If a Diamond Is Only Shane Co. Certified?
What Does It Mean If a Diamond Is Only Shane Co. Certified?
If a diamond is only Shane Co. certified, that means that we have used our internal lab to evaluate the diamond. Shane Co. adheres to strict diamond grading standards, like those used by the GIA and other reputable diamond labs, and we often go above and beyond these standards. Our internal graders have had extensive training within GIA’s curriculum, a big part of which involves looking at hundreds of diamonds and aligning our eyes with industry leaders. By incorporating grading standards from well-respected labs, we are able to provide educated and dependable certifications from our internal lab.
 
 
What Is Included in My Diamond Certificate?
What Is Included in My Diamond Certificate?
When you receive your diamond report, it will have a section at the top relaying the diamond type, its measurements, shape, cut, and the report number. This will be followed by a section with its grading results pertaining to the 4Cs. It will then list any additional information, such as the quality of the polish, fluorescence, and symmetry. Many reports include a graphic showing the location of the diamond’s inclusions and a graphic showing the diamond’s measurements. As you browse our selection of loose diamonds, most of them link to the diamond report.
