The main diamond is GIA assessed and reviewed for colour, clarity, cutting and transparency. Choose your preferred size, metal and ring size; we take care of selecting and setting the stone.
The first grade on the D-to-Z scale: colourless
Tiny inclusions are difficult to see at 10× magnification

WHAT WE SELECT FOR YOU
What makes our Premium main diamonds different?
VVS2 or above: inclusions are difficult to see even with magnification
VVS2 is a very, very slightly included clarity grade: its tiny inclusions are difficult for a skilled grader to see at 10× magnification. We also check the eye-clean appearance and transparency, excluding evident milkiness, haze and cloudiness for a visibly clear stone.
Explore RAGAZZA’s selection checks ↗Round diamonds: 3X means three Excellent grades
3X means Excellent cut, polish and symmetry. Cut concerns light performance, polish the surface finish, and symmetry the precision of facet arrangement. We also compare brightness, fire and the balance of dark areas. Fancy shapes are assessed for their own outline, length-to-width ratio and facet structure.
Explore diamond shapes ↗D colour: a colourless appearance
D is the first grade on the diamond D-to-Z colour scale and represents colourlessness. We select D-colour main diamonds and check for unwanted colour casts or dullness. Accents are compared for colour, transparency and light so the complete ring looks clear and coordinated.
Round main diamonds: DAII™ 7.00 or above
DAII™ is RAGAZZA’s index using 16 data points to analyse round-diamond proportions and overall quality; 7.00 is our Premium selection threshold. Video, direct observation, ASET viewing for light return, and Hearts & Arrows viewing for optical symmetry support the visual review. The score applies only to round brilliant main diamonds.
DIAMOND ASSESSMENT
GIA assessment for your Premium main diamond
Preset Premium main diamonds include a GIA report for checking origin, weight and relevant quality details. We match the stone to its report and review it with video, direct observation and optical checks against your selected specification.
Main-diamond and accent-diamond details are stated separately. Accent stones do not automatically each include an individual report.

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.
Enquire about availability and production ↗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.
SimplyDuty import duty calculator ↗Payment and delivery terms ↗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.
View aftercare and exchange terms ↗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.
Compare 18K gold, platinum and silver ↗Arrange a PT950 order ↗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.
Ring-size methods and conversion chart ↗Request a free ring-size measuring strip ↗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.
Explore lab-grown and natural diamond appearances ↗Diamond cleaning and care guide ↗What are the Premium requirements, and does DAII™ apply to fancy shapes?
Preset Premium main diamonds are GIA assessed, D colour and VVS2 clarity or above. D means colourless; VVS2 means tiny inclusions are difficult to see at 10× magnification.
Round brilliant main diamonds additionally require 3X (Excellent cut, polish and symmetry) and DAII™ 7.00 or above. DAII™ is the brand’s 16-point round-diamond quality index and is not applied to fancy shapes, which are reviewed for their own outline, facets and visible light.
Can I choose another main diamond for a particular preference?
Yes. For the preset specifications above, our team selects the stone to the stated standard. For a particular preference, choose a suitable loose diamond and order it with the setting-only option, or contact us for help. A separately chosen diamond follows its own stated grade and report.
