of Experiences
Welcome to Rocu Gems Trading. We are a private Minerals company that was started and registered in November 2015 by the registrar of companies in Tanzania.
Since the company was started there have been large growth and improvement in the operation of our business. Exploration activity is managed by professional skilled and technically competent personnel and is accompanied by an international team of geologists from Tanzania with years of proven experience.
“With almost 10 Years in the industry, in-house cutting center and master cutters, close connections with mine owners in East Africa and long experience running colored stone mines,”
We offer a vertically integrated service from the mine to the end consumer bypassing the established old chain of distribution and its many built in markups. Our extensive network of miners provide us with the opportunity to have first viewing and selection of all new strikes and production from the mines.
We buy rough rare gemstones directly from small-scale miners all over the region. We have developed close relationships with these miners over the years. We then cut the material right here in our local factory and we either sell to you rough or cut or polished gemstone.
There is no middleman; our gemstones come from the ground directly to you!
I have been in search for a Tanzanite for quite some time now. I contacted The ROCU GEMS regarding a Tanzanite that I found on their website. I applied for an account and was assigned a gemologist by the name of Antony. That’s where I hit the jackpot. He was very professional and walked me through the entire process. He answered so many detailed questions.
I am extremely satisfied with my purchase from this company. The product is superb and exceeded my expectations in every way. Additionally, the service I received was excellent. The staff, Lucas was friendly and helpful, and he went above and beyond to ensure that my experience was positive. I would highly recommend this company to others, and I will definitely be a returning customer in the future.
I ran across this website during my search for a matching pair of tourmaline gemstones. I am not an expert in gemology but I am extremely satisfied with this purchase. I selected pear shaped gemstones to complement my tourmaline trillion cut necklace. I very much appreciated the personal touch by having a gemologist allocated to my account. Also, the Mining & Geology Report and Grading Report was much appreciated
