    This gorgeous spinel is the second stone I've bought from Ian, and it's clear that he has a magic touch when it comes to cutting gems. My spinel is perfect, I can't find a single flaw with it. It almost seems to glow from within in some types of lighting! Ian's precise and scientific approach absolutely pays off. The gems I've received from him haven't simply exceeded expectations - they've demolished them! It may be a little while before I can get these beauties set, but I'm excited to wear them proudly.

    By the way, the white gem pictured is the first one I bought from him. It's one of my favourite cuts (Arya Akhavan's Ruination) in Lithium Niobate, a very rare material indeed. Photos can't really show how many diamond sparkles this thing throws around. An absolutely dazzling treasure!

About PrecisionCutGems

On Etsy since 2018

I am a part-time physics researcher and gemcutter. The two share an obsession with precision and symmetry. My lapidary experience goes back to the 1970s starting with a professional tumbler. Using a modified Polymetric faceter I cut gemstones for their own sake rather than as a business. Cutting to optimise aesthetics rather than maximise weight I will often spend upwards of 30 hours on an individual stone until I am satisfied with the gem.

You will not find gemstones cut and polished to this standard on the high street!
