Shopping for a Loose Diamond – What Do I Need to Know?

If you’ve done some searches online, you may know about the 4 Cs and some of the considerations that go into choosing a loose diamond. At the end of the day, it’s about selecting the prettiest diamond that fits within your budget and getting the best value. And at Henne Jewelers, that’s what we strive to do for every single customer.


What to Know About Diamond Laboratories & Certifications

There is a lot to consider with diamond laboratories and certifications. There are many ‘certified’ diamonds out there, but numerous standards of quality among the laboratories.

At Henne we only sell natural diamonds certified by the Gemological Institute of America (GIA) or American Gem Society (AGS), both of whom are non-profit organizations that set the industry standard for excellence. The GIA’s grading system is recognized, used, and trusted worldwide.

Henne’s Loose Diamond Sourcing & The Kimberley Process

At Henne Jewelers we are deeply passionate about running our business with integrity, fairness, and sound business practices. With that in mind, we’ve taken many steps to ensure that we purchase our diamonds, gemstones, and gold with ethical sourcing methods and from conflict-free zones.

  • We of course adhere to the Kimberley Process.
  • We sell stones that comply with the World Diamond Council System of Warranties.
  • We provide a country/region of origin certification on nearly every colored precious stone that we sell.
  • We fully disclose all treatments (if any) applied to the precious stones we offer for sale as per the FTC and CIBJO guidelines.
  • We do not deal in ivory or any other material listed as endangered or restricted by CITES or the U.S. Fish and Wildlife Services.
  • More than half of the gold and platinum we use in-house to manufacture or repair jewelry is recycled or sourced from refiners that recycle our material.
Finally, we are members of the American Gem Society, Jewelers of America and employ gemologists holding GIA, AGS and Gem-A credentials – all of whom operate via strict ethical standards.
