House of Diamonds in downtown San Diego's Gaslamp Quarter has specialized in fancy colored diamond sourcing and couture micro-pavé fabrication from Suite 612 of the Jewelers Exchange since 1991. The firm supplies both wholesale trade accounts and private clients from the same inventory, a dual-channel approach that complements the retail engagement ring specialization at Diamond Daughters INC elsewhere in the building. As a Jewelers Vigilance Committee member, House of Diamonds maintains Federal Trade Commission compliance on gemstone origin disclosure across every B2B and consumer transaction. Nationwide wholesale ordering ships same-day through its Pacific Time Zone logistics window, accommodating jewelers restocking mid-week without next-day delay. High-value wholesale transfers above five figures generate notarized bills of sale through document services like Downtown Mobile Notary & Apostille Services, ensuring chain-of-custody compliance for each stone. Investment-grade pieces involve individually GIA-graded fancy vivid diamonds exceeding two carats, certified for color origin, saturation intensity, and fluorescence characteristics.
