1 on 1 gem cutting: standard round brilliant or diamond cut: meetpoint faceting

Golden topaz standard round brilliant


Hello! My name is James Langdon and I will be giving the tuition. I have been a self employed gemcutter since 2008 and have sold gems to gem dealers and jewellers in Hatton Garden as well as internationally through instagram. I cut cabochons, faceted gems and concave cut gems too. This short course covers faceting a standard round brilliant or diamond cut: you will need to have completed one of my two cabochon cutting lessons and also my step cut square faceting lesson.

Before you arrive I will have selected a rough citrine or amethyst and fixed it to a faceting dop so we can make a start as soon as you arrive. You'll have a bit of experience as to how to make a start but I'll guide you through the processes involved in getting the gem symmetrical and centered on the dop, from preshaping to final polish. As you progress through the work on the pavillion i will be observing and offering advice and guidance where necessary and will take over should you get stuck.

Once the pavillion is complete another faceting dop is glued to your gem to allow the faceting of the crown of the gem. The glue takes 25 minutes to cure so at that point there will be a break for tea or coffee and a chat / question and answer session about faceting.

Next up, the crown of the gem. You should have a reasonable grasp of faceting by now but I will be observing, offering advice and giving instruction where appropriate for the duration of the cutting. I'll take over if you get stuck.

After your gem is finished it needs to be soaked in a solution to dissolve the glue. This can take up to 24 hours so your gem will be ready to collect the next day, or, if that's not convenient it can be posted to you by Royal Mail special delivery at no extra charge.

Please be aware that the stairs to the toilet are very steep and not suitable for anyone with any difficulty walking.
I can teach most afternoons and evenings, please enquire for availability.

My workshop is close to Lewes Road in Brighton and there are several bus routes available which use that road. The closest bus stop is St. Paul's street which is a 3 minute walk away.

The tuition runs for approximately five hours but I'm quite happy to extend the time available until the faceted stone has been properly finished.
This lesson is not suitable for beginners, you need to complete one of my two cabochon cutting lessons which include an introduction to faceting and my faceting basics step cut square lesson. A standard round brilliant has 49 facets and meetpoint faceting is difficult. Not for the faint hearted!

Cancellation and a full refund can be obtained up to 2 weeks before the course starts. Start dates may be amended on request.

What's included in the price?

Water, tea or coffee, biscuits.
A rough facet grade quartz.
Postage of your gem to you by royal mail special delivery if necessary.

Had a fantastic time with James, a very insightful lesson. Enjoyed James's company, he is an exceptionally talented cutter and always willing to give advice during and after the course. Thanks James!

James :)

I myself give thumb up on this course from James. Nice man with good knowledge on lapidary arts of cutting. Giving yourself experience to playing around with gemstone cutting. You will end up making that stone yourself of cos with the master Yoodaa instructing you.
Instead wondering around on the internet for answers, is quicker try it yourself and bring home knowledge that you will pride for.

Response from Treasureworks:

Thank you Peter! It was a pleasure meeting you and you were an awesome student, a pleasure to instruct.

I've never been compared to master yoda before and it's a great hounour. I must say this:
Hmmmmmmmm! Facet you will!
Now you understand the way of the uncompromising critical angle, much light you will reflect from the darkness...

All the best for 2020!
James :)
