Testimonials

★★★★★

I met with Carlos to talk about a project in silver. the pieces are something that would be nearly impossible to make molds for so I needed to print 3D wax. He was understanding, knowledgeable, and accommodating. His craftsmanship is like no other in NYC's jewelry district. The castings are gorgeous. Your project is in good hands with Carlos and Tech-Designs.

For the people who reads this review and need a honest opinion regarding Tech Design I can say one thing, just this year alone Carlos did over 20 projects for us in witch we generated over 3 million in purchase orders. His CAD skills are at the highest level of jewelry manufacturing and because he is a jeweler and designer he makes everything work flawlessly. I would definitely recommend Carlos and Tech Designs.
