Selecting the perfect stone

Diamonds are an expensive luxury, of that there is no question. Their exquisite beauty makes them an object of desire for people from all corners of the globe and their rarity ensures that their price remains high. Whether you would like to invest in a beautiful necklace, a ring set with these sparkling gems, or a quantity of loose stones, it is a good idea to spend some time learning how to select the perfect examples.


The four Cs

Cut, clarity, carat and colour are known collectively as the four Cs and each one should be considered carefully when choosing a stone. Additional factors that you should learn about before making a purchase are listed below.

  • Fluorescence
    the colours revealed under ultraviolet light can have a big effect on the value of a stone.
  • Certification
    a certificate of authenticity from a recognised institute is of vital importance when looking for the perfect diamonds to buy. The American Gem Society Laboratories, Gemological Institute of America and Antwerp Diamond High Council are our preferred certification authorities.
  • Provenance
    ensuring that the stones in which you invest are conflict-free has become increasingly important in the modern world and you should always deal with a supplier that can guarantee all their stones are ethically sourced.
  • Laser inscriptions
    to make your stone easy to authenticate at a glance, a laser inscription, which is invisible to the naked eye but easy to read under a jewellers loupe, is an excellent idea. The certificate number and brand name of the jewellers from which you buy your stone can be accompanied by a personal message if you are purchasing a gift.

We believe that every customer is entitled to complete satisfaction when buying stones from us or any other supplier, which is why we created this diamond education centre.


Fluorescence by Fire or Gentle Ember

Fluorescence is the gentle colour, your diamond may reveal under ultraviolet light. Often times your diamond appears pristinely clear to adoring naked eyes. Yet ultraviolet light will frequently uncover glowing highlights:

  • Blue
  • Green
  • Yellow
  • Orange

Fluorescence lends stunning increase to your diamonds’ value. Enhancing visual appeal beyond its official colour grade.  Fluorescence checking or certification can reveal your diamond to be an even truer treasure.  Don’t forget to check your authentic diamond certificate for fluorescence levels too.

Conscience as Clear as White Diamonds

Social responsibility is an important facet underlying diamond selection. Perhaps you have heard of ‘blood diamonds’ or ‘conflict diamonds’. Stones sourced from war torn countries where diamond mining, funds violence and propagates worker exploitation. No diamond should come at so great a human cost. So choose a diamond wholesaler that guarantees only ethically sourced diamonds. You may ask:

  • that your diamond be accompanied by a certificate of origin
  • whether your diamond wholesaler complies with the Kimberly Process Certification Scheme (KPCS)
  • to see your diamond wholesaler’s policy on ensuring conflict free diamonds
