Looking at the qualities of coloured stones and their values.

On Sunday 18th April I hosted my first Gem Quality and Values Workshop in Hatton Garden. Retailers, jewellery valuers and dealers attended the day to examine a large spread of gems of various qualities supplied by Tracy Jukes, each priced at current UK wholesale prices per carat.

We discussed how the variation of colour (saturation, tone and distribution), transparency, clarity and cutting precision and style influences prices. The importance of certification of prized gems, e.g. padparadscha sapphire and Paraiba-type tourmaline was considered with examples.

How the variation of supply of gems mined over time, the demand by retailers and the public for certain gems and how current political and legislative developments influenced current UK prices of gems were considered with reference to examined gem varieties.

The day finished with Tracy showing examples of current ruby, sapphire and emerald treatments and Man-made stones. Their UK prices were noted and future likely trends in demand discussed.

The next workshop is on Monday 5th July.

Excellent and relevant workshop. More retailers and manufacturers should attend something like this in order to understand and explain to the consumer. I’ll have to book a place at some point.
