Beyond the Diamond: RAGAZZA DIAMOND’s Jewellery Craftsmanship and Quality Checks
Updated: 1 day ago
The quality of fine lab-grown diamond jewellery comes from good diamonds and good craftsmanship working together. Before delivery, RAGAZZA DIAMOND checks the order and centre stone, then examines the setting, metal finish and wearing details so that the finished piece reflects the requirements agreed with the customer.

1. Great Diamonds Need Great Craftsmanship
The quality of fine lab-grown diamond jewellery depends on both the diamond and the craftsmanship. A centre stone’s brilliance and fire matter, but the proportions of the setting, the lines of the prongs, the metal finish and the way the piece feels when worn also shape its overall refinement.
Even a beautiful diamond can lose its impact if the stone sits at an angle, the prong tips feel rough or tool marks remain on the band. RAGAZZA DIAMOND therefore extends its quality requirements to the setting, metalwork and checks before delivery.
Below are the key areas we inspect before delivery. The checks are arranged according to the type of jewellery, metal and design confirmed by the customer.
2. Checking the Details You Approved
Inspection starts with the order. We verify the style, quantity, metal and colour, then compare the piece with the final approved design to check its proportions, components and custom requirements.
For the centre stone, we check the gemstone type, whether it is natural or lab-grown, its shape and its specifications. Colour, clarity, carat weight and cut details are compared with the certificate and pre-setting records. For stones with a certificate and laser inscription on the girdle, we confirm that the inscription matches the certificate number and corresponds to the correct order.
The girdle inscription must also be clearly readable. If a prong obscures it, the setting needs adjustment. For custom engraving, we check the wording, font, direction and position so that these details match the customer’s requirements.
3. Inspecting Gemstones and Settings
After setting, we inspect the centre stone and accent stones under magnification for any new chips, broken corners, cracks or scratches. Particular attention is paid to the girdle, pointed corners, the underside of the stone and the areas where the stone touches the prongs.
Using an appropriate tool, we gently check the centre stone and examine each accent stone for looseness, movement or unusual sounds. We also check the centre stone’s position, orientation and height, whether the prongs sit closely against the stone, and whether the prong tips are raised or have burrs. The stone seat and prongs are examined for cracks or weak areas.
The number, shape, size and arrangement of accent stones must match the production sheet, with a consistent colour and appearance. For closely set designs, we also look for stones pressing against or touching one another.
Whether pointed corners are covered is checked against the customer-approved design. Some bespoke designs leave these corners exposed, so the inspection follows the setting structure and requirements of that particular piece.
4. Examining Metal Structure and Finish
Metal plays an important role in a piece’s shape and structure. We inspect the ring band, stone seat, pendant loops and chain links for deformation, cracks or weak areas, and look for pits, pores, dents or missing metal.
Soldered joints need to be secure and even. Resized or repaired areas should be smooth, without affecting the structure or the stones. Openwork and pierced designs are checked for blockages or residual metal.
We check that polished, matte or brushed finishes match the requirements, and look for scratches, tool marks or areas thinned by excessive polishing. For plated pieces, we examine the coating for evenness, exposed base metal, blistering, peeling or unusual discolouration. Two-tone metal designs are checked for clear boundaries and colour overlap.
Where required by the design, we also verify the metal fineness and centre-stone weight markings. Engraving is checked for doubled impressions, burrs or any effect on the jewellery’s structure.
5. Checking Size, Fit and Comfort
For rings, we check the ring size using a standard metal mandrel and ring gauge, taking the sizing system into account. We check roundness, width, thickness and height against the design and production drawing, and confirm the lengths of necklaces, bracelets and extension chains.
Wear-related checks include whether the inner band, edges and underside are smooth, and whether any part could scratch the skin, catch clothing or hair, or press uncomfortably against the wearer. We also view the piece from the front and side to check its proportions and symmetry against the design.
Chains, pendant loops and joints should be securely connected and move smoothly, while pendants should hang in the intended direction. Clasps, safety catches and detachable components are checked for opening, closure and security according to their material and design.
For earrings, we compare the size, colour, accent stones and orientation of the pair. We check that posts are straight, tips are smooth, and earring backs, screw-back fittings or hoop closures have suitable tension and function properly.
6. Cleaning, Rechecking and Preparing for Delivery
Cleaning before delivery is mainly handled by our front-line team, with production colleagues assisting where needed. We choose a method suited to the gemstones and construction, remove fingerprints, oil, polishing wax and cleaning-agent residue, and pay attention to the undersides of stones and small gaps.
After cleaning, we recheck the settings, surfaces and clasps. Any item that needs adjustment is inspected again once the work is complete.
Before dispatch, we verify that certificates, sales documents and labels correspond to the piece, and that earring backs, extension chains and other included accessories are complete. Packaging should be clean and intact, with the jewellery secured to prevent tangling or rubbing against other items. The shipment contents and recipient details are also checked.
RAGAZZA’s standards for fine lab-grown diamond jewellery are reflected in these practical details. A well-chosen diamond needs a setting and metalwork that complement it, so that the finished piece meets the agreed requirements for appearance, structure and comfort.
If you are choosing a diamond ring or commissioning bespoke jewellery, our RAGAZZA advisers can explain the centre stone, setting and craftsmanship in more detail. You are also welcome to arrange a showroom visit to compare pieces in person.
