From       to       

ManGo         Massimo Dutti

Our journey in Europe began with designs from the Spanish brand Mango. Through gradual adaptation and collaboration, we established a solid foundation of trust with designers and brands, expanding to partners like Massimo Dutti. Clients demand minimalist metallic designs tailored for upscale markets, driving us to innovate with premium materials and cutting-edge technologies. European customers’ focus on sustainability has spurred our R&D team to pioneer eco-friendly materials, aligning with global environmental standards.

From product excellence to top-tier service, we believe every client need—no matter how small or large—deserves full attention. Through relentless effort, we've built win-win partnerships from concept to execution, expanding collaboration into new horizons.

Looking ahead, we'll seize new opportunities and challenges together, forging breakthroughs and growth.

Our Commitment

Sourcing Offices

Our Hong Kong Sourcing Office regularly sources materials from Yiwu, Dongguan, and Guangzhou. Offering customization tailored to customer specifications, we combine global material trends with R&D collaborations to innovate. For example, we explore sustainable options like recycled materials and PLA (polylactic acid).

Mold Making

Molds are crafted per client specifications using traditional methods, then designed/computer engraved based on their data. Prototypes are 3D-machined to finalize designs.

Brass Casting

Brass castings offer softer, more malleable properties than alloy castings, making them ideal for intricate, elegant jewelry designs. While traditional brass castings are heavier, our innovative techniques enable precision-crafted pieces as thin as 0.5mm—ensuring both sleek aesthetics and wearer comfort.

Alloy Casting 

For quantities exceeding 20,000 units of the same component, casting with molds achieves 40-50% cost savings compared to silicone rubber molds. Cast alloy parts also exhibit superior quality and aesthetics over those from silicone molds.

Collaboration and creativity drive our custom jewelry design process. We start with a detailed consultation to deeply understand your brand identity and vision: this foundational phase ensures bespoke pieces that reflect your style while aligning with your core values. Every creation tells a story that resonates with your brand's essence, crafted with precision through open communication and shared excellence.

Consultation 

At DiDiG, skilled designers transform your vision into art. Whether you have a concept or need inspiration, we collaborate closely to design jewelry that embodies your brand's uniqueness. From sketches to digital renderings, every step ensures the final design captures your brand's essence.

Design 

Our meticulous material selection reflects a commitment to quality and elegance. Custom gold jewelry uses 14K/18K gold for luxury and durability; sterling silver offers strength and versatility, while brass blends affordability with style. Gemstones, pearls, and diamonds add timeless sophistication, ensuring each piece exudes unmatched elegance.

As a premier custom jewelry manufacturer, we combine high-quality materials with meticulous prototyping to exceed client expectations. Every creation reflects our dedication to quality, innovation, and your brand's unique vision.
