When I entered your building, I was warmly greeted by your staff member. She introduced me to the history of your company’s establishment, your diamond mining and production processes, and allowed me to observe the jewelers at work, expertly polishing the facets of the diamonds. She also showed me the various sizes of diamonds and provided advice on their quality, size, color, and more to help evaluate the value of each type. I sincerely thank your company for allowing me to learn about how you operate, from the mining, production, to the quality assessment of the products, as a leading company in the world’s diamond production industry.
I hope I will visit your company again as soon as possible.
