A jewelry manufacturer in Wuzhou, Guangxi — cutting, setting and finishing moissanite, lab-grown diamonds and colour stones since 2008.
Holycome is a jewelry manufacturer, not a retailer with a stockroom. We cut and set moissanite, lab-grown diamonds and lab-grown colour stones in our own workshop in Wuzhou, Guangxi, then ship directly to the person who wears the piece. There is no distributor, no showroom rent and no brand markup between the bench and your door.
The business began in 2008 as a jewelry shop on Shatou in Panyu, Guangzhou — a counter, a bench and a wholesaler's account. By 2010 we had brought setting and polishing in-house, and by 2012 we were taking custom work from drawings. The pattern has not changed since: design, sample, produce, inspect, ship, all under one roof.
The Wuzhou company was registered in 2020 and the current 8,000 m² workshop opened there. Wuzhou is the jewellery-manufacturing city for synthetic gemstones in China; being inside that supply chain is why we can quote a custom ring in a day instead of a fortnight.
Everything is made to order. You choose the metal, the stone, the size and the setting; we model it in CAD, send the render, and cast only after you approve it. That is slower than pulling a box off a shelf and faster than most custom processes, because the model is built by the same team that will set the stones.
Alongside HOLYCOME we operate HMOL, PH2, FGJ and BELLE across marketplaces and wholesale channels. The workshop, the stone buyers and the quality standard are shared; the retail channels are not.
