Choosing a Diamond Ring

When you are choosing an engagement ring, wedding ring, eternity ring or a diamond ring as a gift for that special person, it is important that you make the right decision. A diamond ring is a significant purchase and one that requires thought and research.

ZS Diamonds are committed to helping our customers make the right choice. Our guide to the 'four C's' of diamonds is based on our knowledge built up over 50 years in the diamond industry and training by the GIA that is designed to help you make an informed decision based on the facts about diamonds.

Custom Made Diamond Rings

Our engagement rings are custom made in the UK; you really can find the perfect ring with ZS Diamonds. After learning a little bit about the different types of diamonds and the grading levels and how they work, we hope you will be able to select the diamond of your dreams.

The four C's as referenced in the jewellery industry refer to the carat weight, colour, clarity and cut of a diamond. The other main classifications involved in diamond grading are certification and shape.

Every diamond above 0.29ct purchased from ZS diamonds comes with a diamond certificate, providing an independent report detailing the dimensions, clarity, colour, polish, symmetry and where appropriate cut, of the diamond. ZS Diamonds only sell diamonds certified by the leading authorities in diamonds, so all of our certified diamonds come with AGS, GIA, HRD or IGI certification.

Nine Different Shapes of Diamond for Your Ring

ZS Diamonds offer the choice of nine different shapes of diamond, including princess cut diamonds, emerald cut diamonds and marquise cut diamonds, any of which can be combined with your choice of band to make the perfect diamond ring. For cuts such as triangle, trillion and radiant please contact us.
