A Hidden Gem on Morello Ave!…read more I recently brought my broken necklace into this little jewelry repair shop on Morello Ave, and I couldn't be happier with the experience.

The level of care and craftsmanship was outstanding. While I was waiting, I browsed their display and was impressed by the selection of stunning 14k jewelry and precious gemstones.

These were reputable organizations, but I wanted to do business with someone local for transparency. It was a blessing an on-line inquiry led me to JLS Diamonds and Jim Dinse. The auction house companies could only offer me a fraction of what I wanted for my diamond solitaire ring; less their commission, and only if they could sell it. On the contrary, Jim actually found a buyer for my ring before I even met with him; and before my ring left my possession. In fact, Jim paid me exactly what I wanted for my ring via cash transfer on the spot! Jim turned a stormy time in my life into a rainbow with a pot of gold! I could not be more grateful! One Month Later ..... I was so grateful and impressed with Jim's professionalism, honesty and integrity, I returned a month later to sell him a coin collection. I trusted Jim implicitly. Jim paid me TOP DOLLAR for it and I was actually shocked at its value.! I am definitely going to shop with JLS Diamonds and Jim Dinse FIRST for my jewelry needs before shopping retail in the future! If you are looking for a resource in this market don't even think about it; CALL JIM AT JLS DIAMONDS NOW AND MAKE AN APPT! You won't be disappointed!
