First and foremost , I gotta congratulate you for thinking outside the veritable and true box around us in the secular world and taking that desire of becoming an entrepreneur jeweler to the next level Secondly, the moment we think we've actually gotten "somewhere" no matter what weve accomplished is the moment we lost it Thirdly, Id say, you've already started your entrepreneurial journey today by just asking, Ive learned so much by just listening to other jewelers over the years, put aside personalities and take what snippets of wisdom or experience however little or large that other jewelers share with you Lastly, do business and be honest , if you mess up something talk to the customer and repair or replace what happened, if they are not very merciful still be compassionate you might have ruined (whether in just the imagination of the customer or not) a very sentimental piece. We all post our best work on the internet like the accomplishments of the ancients, mainly never being candid about their own mistakes, but honestly every jeweler has really destroyed a valuable piece or two in their career Above all else, dont give up, we need entrepreneurial jewelers in a disposable cup world, and a world where people buy a thousand dollar phone, only for it to be outdated and exchanged 6 months later, while true masterpieces of jewelry such as the Catherine II of Russia emerald, Duke of Wellington chatelaine and watch, Faberge, Cartier to the incredibly complex Zuni Petit point turquoise work, Fred Peshlakai's smithing , and yes even the native amongst the deserts who pawned their silver, in which today we call and value "old pawn" native silver pieces above even many diamonds and emeralds of Tiffany & Co will be here as they have been, even before most of us reading this have been aliveYes lastly, everyone of these true jewelers had passion for their work. Never cease to have that.
