My approach is entrepreneurial, transparent and results-oriented. Whether sourcing a sapphire for a custom ring or a matched pair for a collection — I am here to make your decision easier and more confident. Available in English, Portuguese and Spanish.
"Rafael helped me source the perfect sapphire for a custom ring. The stone matched exactly what I had in mind — color, size and budget."
"Excellent sourcing support. The emerald options were beautiful and much more aligned with my budget than what I was finding on my own."
"Professional and transparent. I appreciated the guidance on what actually made commercial sense for resale in my business."
"Instead of pushing a sale, he genuinely helped me choose the right stone for my project. That honesty is rare and I will always come back."
Both. We supply jewelers and designers at wholesale, and private clients and collectors are welcome too.
