What our customers are saying
THANK YOU for your diligent work. I also wish to commend you and your staff for their speed in completing the task of completing my order. Your personal contact with me via telecom, keeping me informed, shouts highly of your dedication to your clients and your outstanding professionalism as a man of business. Please feel free to use me as a referral to any future customers. Sithy Gems will always be a AAA+ company.
They are fabulous! I was incredibly impressed with your ability to cut these stones for optimum beauty, artistry, and clarity, especially given the fact that these were stones previously rejected by another gemcutter, because they said they were too fractured or cracked to cut. Now I have beautiful, faceted stones I can use or give away as gifts instead of just the raw minerals. In addition to this, your prices were much less expensive. I have already recommended your services to a friend of mine.
I am extremely pleased with both the workmanship, and the professional way this transaction was handled. You should be very proud of your company, and cutters. They certainly deserve my heart-felt thanks and gratitude.
I am extremely happy with the results of your cutting! I realize there was not much to work with in some of the peridot crystals, but you certainly maximized everything that I sent and that was extremely important to me as I needed the smaller sizes.
I just wanted to let you know that I got my gemstones back today. These are AWESOME! You guys did an amazing job and I would recommend you to anyone. I will definitely be using your services in the future, thank you very much!
I've looked carefully to the other stones and they are very impressive too, especially your artistic cuts. Thank you again for your work and for your availability and I hope to work again with you.
