Microscopy and Photomicrography

 

 

The ability to combine microscope use and photography enables a valuer to not only identify inclusions, confirm natural or synthetic origin, but also share this information, whether for interest’s sake, or if a valuation conclusion is challenged, and can therefore be a vital addition to those ever-important working notes.

 

If you have ever struggled to manipulate microscope, camera, lighting and stone tongs, often with all too- disappointing results, this is an outstanding opportunity to rectify all that, under the expert eye of one of the best in her field, and in an ideal venue.

Spaces are limited, so please book early.

How to value Asian jewellery based on the Asian market in the United Kingdom

 

The Academy of Valuers is delighted to announce availability for its upcoming assessing Asian jewellery workshop.

 

This workshop is designed to give a brief outline of how to identify and value Asian jewellery based on the Asian market in the United Kingdom. To differentiate between some of the various types of Asian jewellery, to discuss factors to be taken into consideration when valuing Asian jewellery and what valuation methodology to follow to arrive at the most appropriate value conclusion for that item.

Assessing Diamond Jewellery

 

Diamonds are the backbone of our industry, and whilst they seem to be relatively uncomplicated in comparison to coloured stones, with their standardised grading and price lists, this is actually not the case at all when you start to delve a bit deeper. It is important for anyone working with diamonds to have a solid foundation of knowledge in the assessment of diamonds.

 

This one day workshop looks at the process of assessing mounted diamonds. It is a hands-on workshop designed to give valuers a basic understanding and the ability to assess the quality and value of mounted diamonds. This workshop will give an introduction into the identification of diamond from its simulants, the assessment of the 4 c’s, carat, cut, colour and clarity, how these factors affect value, and a brief understanding of interpreting these value factors, why when on “paper” two diamonds may appear the same but have very different values.

 
Practical Polariscope... How to use your polariscope for much more than a bookend!

 

This half day workshop looked at the use of the polariscope. It was a hands-on workshop designed to show how understanding and correct use of the polariscope can be of great help to valuers, jewellers, working gemmologists or anyone working in gemstone identification. This workshop showed, with the use of practical examples what the polariscope can do to help identify gemstones, quickly and simply.

The workshop was suitable for people who have never seen a polariscope, to seasoned gemmologists who want a refresher. Delegates will had the opportunity to practise with a wide range of stones, so they could learn from known examples what to look for and what this can tell us, as well as practising their new skills on unknown stones.

 

Chasing Rainbows... How to find and use those elusive spectra

 

 

This half day workshop looked at the use of the spectroscope.

This workshop showed, with the use of practical examples how quick and easy it can be to find a spectrum and how much use this can be in identification of gemstones 

The workshop was suitable for people who had never seen a spectroscope, to seasoned gemmologists who wanted a refresher. Delegates had the opportunity to practise with a wide range of stones, both loose and mounted, so they could learn from known examples what to look for and what this can tell us, as well as practising their new skills on unknown stones. 

All workshop attendees received a PDF by email containing handy hints and tips on the use of the spectroscope as well as a list of useful resources.
