Steven Royce Designs has been a family owned and operated business since 1987, specializing in precious stone, tanzanite, and diamond jewelry. We also have one of the largest certified Alexandrite jewelry collections in the world. The concept behind the company is uncomplicated: The color stones we use must meet a high standard. High quality of workmanship is vital. The finished product must be priced to sell. So with that in mind, we have set up buying offices in Tanzania for our tanzanite needs and have buyers continuously searching the market for our alexandrites, rubies, sapphires, and emeralds.
