Ok, so short story time... I am GIA, (gemological institute of america). Being from this and not searching for an apprenticeship at the moment I feel I have very high standards for other stores (and have been very disappointed in work I personally had done)
I would greatly appreciate weigh in on 3 questions.
1. What is the expectations of the physical store? Showcase layout, decorating scheme, and eye catching designs.
2. What screams confidence in the appearance of workers (personally from what Im from its very business casual sort of artsy)?
3. What are you looking for in the work you have had done? Such as resetting a stone, custom design, or even a basic re-tipping of prong work?
