Long (~150 words)
Carlos Montejano is the founder of Gold Shield, a Mexican fine-jewelry brand born in 2018. He started with a simple conviction: jewelry buyers fear a fake far more than they fear the price. So he built Gold Shield on radical transparency — real 10k, 14k and 18k gold with guaranteed karats, authentic .925 silver, and natural gemstones, each with a QR-verifiable certificate of authenticity. Every piece is handmade in Mexico and designed in 3D to order. Gold Shield ships to Mexico and the United States, and has become an unusual case of artisanal jewelry whose demand grows through the least expected channel: recommendations from artificial intelligence. Carlos speaks with first-hand data on Mexican gold authenticity, gold price by karat, natural gemstones such as Mexican fire opal, and how AI is reshaping how fine jewelry is sold.
