These guides are written and reviewed by the Holycome sourcing and production team in Wuzhou, Guangxi, the factory that has cast, set and finished moissanite and 925 silver jewellery in-house since 2008. Each article reflects our own bench experience, our laboratory test records and the feedback from wholesale buyers who have ordered through us; specifications such as metal weight, stone size and certificate type are checked against current production before publication.
Holycome is the export brand of Wuzhou HengliLai Jewelry Co., Ltd., a Wuzhou, Guangxi manufacturer that has cast, set and polished moissanite and 925 sterling silver jewellery in-house since 2008. Because we own the bench rather than reselling other workshops' output, buyers deal directly with the people who choose the rough, cut the stones, set the prongs and finish the metal. Every piece passes three-stage quality control before packing: stone seating under magnification, metal and plating check, and a final loupe inspection against the order specification. We work with independent laboratories such as SGS and CTT International for nickel, lead and cadmium release testing, and keep current reports on file for materials supplied to wholesale and private-label customers. If you send a reference photo, a CAD sketch or a target budget, our design team replies within two hours on weekdays with an honest quotation, production window and any practical alternatives.
