Is this Diamond any Good?

If your answer is, I don’t know or I would like to know, then you have come to the right page!

This is because I want to help you to answer this question and to do this, I have created a short online course to show you the process that diamond professionals go through in order to grade a diamond in a way that you would see on a report from somewhere like the GIA.

But Who Am I?

I thought it would be better to address this part quickly before moving any further down the page.

I’m Paul Haywood FGA DGA and that is my in the picture, I have a very big grin on my face as I was collecting the Gwyn Green Award for my results in the Gem-A’s Diamond Diploma.

The letters that are after my name are all related to Gemmology and Diamonds.

The FGA stands for Fellow of the Gemmological Association of Great Britain and can be used after passing their Gemmology Diploma.

The DGA stands for Diamond Member of the Gemmological Association of Great Britain and can be used after passing their Diamond Diploma, which I did with Distinction.

I am also an AJP from the Gemological Institute of America (GIA) and have taught a practical diamond grading class for both Gem-A Diamond Diploma Students and School of Jewellery (Birmingham) students.

What is in the Course?

As this is an Introduction to Diamonds course, I felt it best to stick with the basics, which when it comes to Diamonds is the 4 C’s but to go through and explain them properly as some of the information that is available for free online isn’t great and sometimes inaccurate.

Below is a brief outline of what is included in the course:



• Understand the unit of weight used for Diamonds
• The equipment that is used to weigh a stone
• How to estimate the weight of a Diamond in Jewellery



• Learn about the Colour grades used for Diamonds
• The process of colour grading a loose Diamond
• How to estimate the colour of a Diamond set in a piece of jewellery.



• Learn about the Clarity grades used for Diamonds
• The process of Clarity Grading a loose Diamond
• How to estimate the Clarity Grade of a Diamond in Jewellery



• Learn about different styles of cut for Diamonds
• Learn about the properties that impact on how good the Cut Quality is
• How to assess the Cut quality of a loose Diamond

To make this course different from all the others out, it isn’t a glorified PowerPoint presentation. Instead, it is me, sat in front of a camera and explaining all these different things, with some practical demonstrations using a very large CZ, which allows me to show you how to do things, which hopefully will allow you to visualise and understand the processes and procedures better.
