What’s the cor gems story?
My name is Muhammad Ali. I am the CEO of cor gems. I am obsessed with two things: gemstones and customers!
My gem career began when I was fifteen years old. It was a sunny summer day and I was at a garage sale with my mother. There was a dollar bin full of books on everything from astronomy to equine studies, but it was the book on gemstones that piqued my interest.
I was amazed by the historical significance, the rarity, and above all the beauty of these treasures from mother nature. I read the book over 20 times cover to cover but it wasn’t enough! I read my way through every book on gems at both my school and public library!
I realized I had to get my hand on the real thing. I turned to the internet to purchase some stones. I was disappointed by how much duller the stones were compared to the pictures in the listings.
It occurred to me that if I was disappointed with my purchase that other customers must be just as disappointed. I began researching gemstone suppliers. Although gems are mined everywhere from Madagascar to Myanmar, almost every gemstone passes through Thailand at one point or another.
Whether it’s to be cut, certified, or sold, the majority of the world’s fine gemstones pass through the Thai border before reaching their final destination. I reached out directly the Thai cutters and built up our Rolodex of contacts.
After years of purchasing as a collector and supplying local manufacturers, I had finally achieved the supplier network that allowed us to take cor gems international.
Today, cor gems is a global powerhouse in the gemstone industry. We have 20,000+ followers across our social media platforms, buyers on every corner of the globe, and a track record for the best customer service in the industry.
None of this would have been possible without my hardworking team, my supportive family, and above all, my amazing customers.
