Buying a Diamond at Joule

Buying a diamond is, for most of us, a “big” purchase! It is considered, planned and often to present at a special occasion or to honour a special person.  Therefore, we understand that choosing the right diamond is incredibly important.   The task can seem overwhelming, with such a vast choice of options and varying prices. At Joule, we strive to ensure clients are well informed and the buying process is enjoyable and definitely stress-free.

Below, we’ve put together a brief diamond guide below to help explain the main considerations.  The infamous 4 C’s, created by The Diamond trading company, have always been the benchmark guide but we’ve added an all important, 5th C!

We hope this will be informative. However, we look forward to welcoming you in store for an informal, no strings attached, conversation about your exact specifications.  At Joule, we promise to keep the romance in finding your perfect diamond -  “The Joule Team”

Diamond Buying Guide

The 4C’s  + Joule’s extra 5th one!

Gemmologists and jewellers assess the physical attributes of diamonds using the 4Cs classification system – cut, carat, colour and clarity.

The 4Cs classification enables the comparison and valuation of diamonds.  No one 'C' is more significant than another, and none will diminish in value over time.

A diamond’s beauty is based on far more than these characteristics.  Each one was formed billions of years ago and has travelled a long journey from deep within the Earth. 

And while most of a diamonds’ qualities are defined by nature, it takes a master craftsman to unlock the diamond’s true brilliance, fire and beauty.
