Kim Thanh Jewelry has sold 24-karat and 18-karat Southeast Asian gold from 4310 Euclid Avenue, Suite C, in College Area, San Diego, since 1987, continuing a goldsmithing lineage the founding family started in Sa Dec, Vietnam, in the 1930s. The store specializes in heavy bridal sets, dragon-and-phoenix bangles, and beaded chain necklaces crafted in traditional Vietnamese, Cambodian, and Laotian styles. Staff speak Lao, Khmer, Mandarin, Cantonese, English, and Vietnamese, making the counter one of the most multilingual retail points along the El Cajon Boulevard corridor in the 92115 ZIP. Bridal hair and makeup sessions that coincide with gold-jewelry fittings run through Rbeauty on El Cajon Boulevard, where the occasion-prep timeline aligns with wedding-set purchases. The partnership of T. Duong, J. Duong, C. Duong, and N. Pho has operated under San Diego business tax account 1987005493, giving the shop nearly four decades of continuous operation in the same Euclid Avenue suite. High-karat gold in 22K and 24K carries the soft luster and deep yellow tone that Southeast Asian wedding traditions require, and custom orders for baby bangles, wedding dowry sets, and Buddhist-temple donation pieces follow traditional weight-based pricing tied to the London gold fix. The intersection of Euclid Avenue and Trojan Avenue places the shop less than a mile south of SDSU, within the dense international retail pocket that includes Vietnamese, Ethiopian, and Mexican storefronts. Repair services cover clasp replacement, chain lengthening, ring resizing, and re-plating of worn gold surfaces back to factory sheen. Weekend grooming runs along El Cajon Boulevard include stops at Pappy's Barber Shop before family portraits, where freshly sized gold chains and pendants finish the look. Each piece is hallmarked with karat purity and the shop's maker's mark before leaving the display case.
