GIA-trained gemologist and stone sourcing consultant based in Torrance, California. I work across three connected markets: natural colored gemstones for jewelry, premium natural stones for kitchens and interiors, and professional gemological services.
My approach is entrepreneurial, transparent and results-oriented. Whether sourcing a sapphire for a custom ring or a Taj Mahal quartzite slab for a kitchen renovation — 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."
"Rafael helped us evaluate natural stone options for our kitchen countertop with a great balance of beauty, knowledge and cost awareness."
"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."
