How to Buy Diamond at Rogers Jewelry Company

The 4 C's

If you’ve never purchased an engagement ring, you may not know much about the art and science that go into making the gem that every woman adores. If you're asking yourself how to buy a diamond, let Rogers Jewelry Co. help!

The first set of questions should be about the 4 C's. This is jewelry shorthand for four traits to be observed in a diamond: cut, clarity, color, and carat. The first two C's determine the passage of light through the diamond, which means that if you’re searching for a diamond rich with the kind of scintillation, fire, and luminousness that make a diamond a treasure, you’ll want to focus on cut and clarity.

Diamond cut must be done according to a specific formula for a given shape, or it may end up too deep or too shallow. A diamond that's too deep will trap light inside the stone, causing the diamond to be dark and appear smaller. A diamond that's too shallow will permit light to seep out in unwanted directions, causing the stone to appear dull and "watery."


Of course, the question then asked is: "How do I know that the 4 C's of my diamond have been assessed properly?" The answer to that question comes in the form of a diamond certification that comes with the stone you've selected. There are a number of organizations that offer certifications for diamond grading, but how can you know which certification is the most trustworthy? Here at Rogers Jewelry Co., there are two major certification groups we endorse: GIA and AGS. These two organizations are regarded as the most thorough and respectable grading laboratories in the jewelry industry, and when you’re looking for a diamond that's right for your engagement ring, we suggest erring on the side of fastidiousness.

Further Questions

Once these questions are settled, there's a few more questions that should be on the docket when you’re browsing diamonds at your local jeweler. It’s important to know if the diamond you’re looking to purchase has been treated to fill cracks or alter the color. These processes can shorten the life of an otherwise durable gemstone. As a member of the Responsible Jewellery Council, we also advise you to ask about the ethical sourcing of the diamond you’re set to purchase. It's important to create a world whose diamonds are conflict-free. We advise you to also ask if your diamond comes with a warranty!
