Starting as a two-person operation in New York City, they combined Matt's manufacturing expertise with a direct-to-consumer vision. Today, 25karats has grown into a nationwide online jewelry company with a team of skilled artisans, jewelers, and customer service specialists, all operating from the heart of Manhattan's Diamond District. The name "25karats" reflects the brand's philosophy: 24 karats is the purest gold, but the extra karat represents their commitment to exceptional service, craftsmanship, and customer care, something beyond the metal itself. 25karats specializes in wedding jewelry: engagement rings, wedding bands, anniversary rings, and custom designs, serving couples across the United States since 2008. ## Policies **Shipping** - Free FedEx insured shipping on all US orders, no minimum order value - Orders $0-$1,000: FedEx Ground (5-7 business days) - Orders $1,000-$3,000: Free FedEx 2-Day - Orders $3,000+: Free FedEx Overnight - International shipping available for a flat fee of $175 (includes insurance).
