COMPOSITION & CRAFT

Each diamond selected for the complete design

Different designs call for different compositions. We select diamonds for the design lines, wearing position and overall proportions so each stone belongs in the finished piece.

Overall proportions

Main stones, accents and settings are considered together for face-up size and visual balance, preserving the design lines.

Coordinated matching

For paired earrings and rows of diamonds, neighbouring stones are compared for colour, transparency, dimensions and light.

The right wearing dimensions

For rings, consider ring size; for necklaces and bracelets, length and fit. Choose from the dimensions listed above.

WHAT WE SELECT FOR YOU

Standard diamonds, carefully selected

VS or above: selected for an eye-clean appearance

VS means very slightly included: a skilled grader can observe minor inclusions under 10× magnification. We further review their position and the face-up appearance for an eye-clean result at normal wearing distance, excluding evident milkiness, haze and cloudiness.

VS+ · EYE-CLEAN

VG or above: good finishing, with proportions and light reviewed

VG stands for Very Good, indicating a good level of cut or finish. We start at VG or above in applicable grading, then examine length-to-width ratio, outline symmetry, facet arrangement and the balance of light and dark areas, screening out visible unevenness, unbalanced proportions and dull light. Each shape is reviewed for its own structure.

VG+ · PROPORTIONS & LIGHT

D–F colourless grades: F or above

Standard diamonds are selected within the D, E and F colourless grades, with F as the minimum. We also review unwanted colour casts, including a noticeable blue tint or grey appearance. For paired and multi-stone designs, colour, transparency and face-up dimensions are compared for a coordinated result.

THE COMPLETE COLOUR PALETTE

The complete colour palette

White metal creates a crisp appearance; yellow and rose gold bring different warmth. We consider the diamonds, prongs and setting proportions together with the metal colour.

DIAMOND ASSESSMENT

Report inclusion follows each individual diamond’s weight

For preselected diamond jewellery, report inclusion is determined by each individual diamond’s weight. An IGI report is used to check that diamond’s origin, weight and relevant quality details.

An individual diamond of 0.30 ct or above

Includes an individual IGI report.

An individual diamond below 0.30 ct

No individual report is included.

The threshold applies to each individual diamond, not the total weight of a piece or pair of earrings.

18K GOLD · CRAFTSMANSHIP · QUALITY

From 18K gold to the finishing details

We recommend 18K gold, bringing precious-metal character, sound structure and carefully finished details into jewellery made to be worn.

75% gold, a considered material

18K contains 75% gold, compared with about 37.5%, 41.7% and 58.5% in 9K, 10K and 14K. At equal weight, it contains more gold and higher intrinsic gold value, and is generally less prone to tarnishing.

Strength for refined details

Alloying improves the hardness of pure gold for fine lines and secure structures. White, yellow and rose gold all share the same 75% gold content.

Precise setting and finishing

We inspect stone seats, prong proportions, fit and security, then review polishing and surface finish for rough tips, visible tool marks and uneven setting.

Checked again before delivery

We verify stones, metal, dimensions and engraving, inspect stone security, closures and smooth edges, then clean and recheck. Any adjustments are inspected again.

PT950 costs the same as 18K gold for the same design. Contact us to confirm production timing. Materials and finishing follow the selected design.

BEFORE YOU CHOOSE

Before you choose

About delivery, aftercare, wearing your piece and diamond quality.

When can I receive or collect my order?

Depending on availability, some in-stock pieces can be collected on the same day or dispatched within three working days. Pieces without ready stock generally require three to four weeks of production. Delivery outside Hong Kong, Macau, Taiwan and Malaysia generally takes ten to fifty-six days, depending on the destination and logistics.

For a particular date or an urgent order, please confirm availability, production and delivery arrangements with us before ordering.

Will I need to pay tax?

Orders for Hong Kong, Macau and Malaysia are tax-free. Taiwan orders carry tax of 5% of the total amount. Other destinations collect import charges under local customs rules.

You can use the third-party SimplyDuty calculator for an estimate, with Hong Kong as the origin for international orders. Estimates are indicative; local customs and courier assessments determine the actual charges.

What care, exchange or return services are available?

Jewellery purchased from RAGAZZA includes lifetime care. Products may be exchanged within seven days of receipt, excluding custom orders. If a product does not match its description, collection and a full refund can be arranged; refunds are otherwise unavailable.

Applicable conditions follow our aftercare and exchange policies. Please contact us about arrangements for an individual piece.

How do 18K gold, platinum and 925 silver differ?

We recommend 18K gold (AU750): 75% gold, balancing precious-metal content, everyday durability and hardness suited to setting. PT950 contains 95% platinum and is naturally silvery white. S925 contains 92.5% silver and tarnishes more readily, requiring more frequent care.

PT950 is priced the same as 18K gold for the same design. Please contact us to arrange it, as production timing may differ and needs confirmation.

How do I find my ring size, and can it be changed?

Use our ring-size guide and conversion chart, or request a complimentary measuring strip from the ring-sizer page. Ring width and finger joints affect the right size; aim for a comfortable fit.

We offer one complimentary size replacement with no time limit. The appropriate arrangement is confirmed for the individual design.

Do lab-grown and natural diamonds look different, and can they become cloudy?

Both are diamonds, with the same fundamental physical and optical properties. Normal unaided observation cannot reliably establish origin; professional testing is needed.

Normal wear does not gradually make the diamond itself cloudy. Surface oils, skincare products and everyday dirt can reduce its lustre, which appropriate cleaning can usually restore.

If anything still looks unusual after cleaning, or dirt is trapped around the setting, arrange a professional inspection and cleaning.

How are preselected diamonds reviewed?

Our Standard selection uses D–F colourless grades, with F as the minimum, VS clarity or above and VG or above in applicable cut and finish grading, followed by checks of eye-clean appearance, transparency and visible light. For paired and multi-stone pieces, our team also compares colour, face-up dimensions and matching within the design.

Which diamonds include an IGI report?

An individual diamond of 0.30 ct or above includes an individual IGI report; one below 0.30 ct does not. The threshold applies to each diamond, not the total weight of the piece or a pair of earrings.
