Our Crafting Process
Our manufacturing process bridges the gap between traditional artistry and modern engineering. Every custom piece begins with high-precision 3D modelling, allowing for a 0.01mm tolerance that ensures a perfect fit for your selected gemstone. While a standard retail ring is often mass-casted, an RCMJ masterwork undergoes over 15 hours of individual hand-refining by seasoned bench jewellers.
Design And Digital Blueprint
- Hand-drawn concepts are translated into highly detailed 3D digital models, ensuring precision from the very first design stage.
- Advanced CAD technology allows us to perfect proportions, balance, and symmetry before production begins.
- Each gemstone is digitally positioned to achieve optimal fit, security and maximum light performance.
- Metal weight and structural integrity are carefully engineered to ensure durability without compromising elegance.
Metal selection And preparation
- Each ring begins with the careful selection of high-quality precious metals, chosen for their purity, durability and long-term wear performance.
- Only metals that meet 95-99.9% purity standards, depending on the alloy are approved for fine jewellery creation.
- Alloys formulations are tested to increase scratch and deformation resistance by up to 40% compared to standard commercial blends.


Casting The Foundation
- Once the metal is finalised, the design progresses into the casting stage, where the concept is transformed into solid form.
- The perfected 3D model is converted into a precise wax prototype using advanced casting technology, achieving replication accuracy of up to 99% from the original digital design.
- Molten precious metal is poured into the mould under controlled temperature and pressure conditions often exceeding 1,000 degree celsius, to ensure uniform flow and complete cavity filling.
Metal and Refinement
- Once the casting process is complete, our seasoned bench jewellers carefully refine the raw metal form to ensure purity and strength.
- Key structural elements, including the prongs, bands, and settings, are reinforced for maximum durability.
- While maintaining high tensile strength, each piece is engineered with a refined, lightweight feel designed for everyday comfort.
- The refinement process removes any casting imperfections, preparing the metal for a final high-lustre polish and rigorous quality inspection.


Stone Selection And Setting
- We move beyond bulk sourcing. Every single diamond and gemstone is individually inspected by our seasoned specialists to ensure it possesses a unique “inner fire.”
- Our gemologists bring decades of experience to the table, identifying subtle nuances in stones that automated grading reports might miss.
- Beyond technical specs, we select for character, the rare combination of personality and presence that makes a stone truly one-of-a-kind.
Final Polish
- After stone setting, each piece undergoes a meticulous, multi-stage polishing process designed to enhance the metal’s natural radiance and depth of shine.
- Skilled artisans hand-polish every surface, refining edges and sharpening fine details to achieve a flawless, mirror-like finish.
- Each ring passes through five to seven individual polishing stages, ensuring consistent brilliance across all angles and surfaces.


Quality Assurance
- CAD modals are reviewed for proportion, balance, and structural integrity before the production begins.
- All settings are examined under magnification to confirm precise alignment, secure claws, and correct tension.
- Each ring undergoes detailed inspection for polish consistency, symmetry, and flawless surface finishing.
- Experienced jewellers perform a final in-house review before approval, ensuring the ring meets our craftsmanship standards.
