Selecting the best diamonds is critical — and often challenging. Avoid these common missteps, and you will be able to deliver on your promise to your customers.

Diamond Buying Mistakes | K. Rosengart

Do not make these diamond buying mistakes…


Settling for subpar cut

Cut is the most important of the 4Cs. An excellent cut maximizes the play of light and optimizes brilliance, fire, and scintillation. Well cut diamonds cost more per carat weight; they are typically not carried by many jewelry stores, so customers select the “best” of what is available. They may choose a 1 carat diamond that is cut so deep that it looks as much as 10 percent smaller. 

Educating your customers about cut quality can help ensure they make the best choice possible. It can also enhance your profit margins. Our expert diamond cutting services deliver exceptional stones that you will be proud to offer your discerning customers.


Not demanding GIA certification 

This is akin to purchasing a house and not having an inspector’s report stating that the foundation, roof, wiring, etc., are all sound. GIA is an independent global organization whose mission it is to protect the diamond-buying public. They provide a grading report for each diamond that explains its cut, color, clarity, and carat. You know exactly what you are getting. You then pass this assurance on to your customers.


Failing to consider ethical concerns

Most consumers want nothing to do with “conflict diamonds” or “blood diamonds.” They would much rather pay for ethically-sourced stones. When you cannot explain the stone’s provenance, it has a negative impact on your reputation. When sourcing your stones, be sure to select a supplier that adheres to the Kimberley Process, a global initiative aimed at eliminating the trade of conflict diamonds.


Overlooking melee diamonds

Yes, they are small, but melee diamonds have tremendous versatility and flexibility. You can select smaller, well cut diamonds and then enhance your designs (and profits) with these tiny stones. A halo setting, for example, makes a smaller carat center stone seem larger and more dazzling.

Going with the wrong supplier 

Not all diamonds are created, or cut, equally. And not all suppliers offer the same level of service and quality. When selecting a source, be sure that they can meet all of your needs, whether it is for matching diamonds to complete a set of earrings or a bag of assorted melee diamonds to create custom engagement rings.

Consider the range of services they provide as well: can they sort and polish? Can they finish your CAD designs or even handle your custom jewelry design requirements for you? Will diamond cutting be executed by an expert hand or outsourced to who-knows-where? Will they ship your order quickly and conveniently? Is pricing consistent and inventories deep? Having the support of a full-service partner is invaluable.

The jewelry world is highly competitive; the key to success is to start with the best supplier. And, of course, the best supplies.
