Brian, This piece is made with 20 gauge sterling, although recently I've moved to using 22 gauge. I've also moved to using argentium sterling silver (92.5% silver, 6.5% copper, 1% germanium) which is even easier to work and doesn't firescale or ever tarnish.
It is still 925 although I think a 980is also available.
I'll definitely be making it over to Stockton to meet you. Maybe I'll squeeze some learning into a visit as it looks like you have a lot happening there. Regards, Jim
