Jewellery purchased from RAGAZZA includes lifetime care. Standard styles qualify for one free maintenance and repair service per twelve-month cycle, within the stated service scope. Non-custom products qualify for one exchange within seven days of receipt. For a confirmed quality issue, customers may choose a refund, exchange or repair.

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

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.

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.

Non-custom rings qualify for one complimentary resizing with no time limit, separate from the one-exchange allowance. Listed large-size surcharges and the specific coverage for custom rings follow the applicable service terms.

This collection uses lab-grown blue sapphire. We have selected its colour direction, considering transparency, outline and the complete colour palette together.

Royal Blue sets the direction for this collection. We select the colour for the natural-sapphire character we seek, then consider its relationship with the complete piece.

Our lab-grown blue sapphires are selected for an eye-clean appearance. At a normal viewing distance, without magnification, the stone should look clean and transparent, without inclusions that visibly distract from its colour and light.

We review the outline, symmetry, edges and overall proportions, together with the light in the finished setting. Balanced contours, neat cutting and proportions suited to the design guide our selection.

A report is not included by default for our lab-grown gemstones. An IGI report can be requested before ordering, with arrangements and any additional cost confirmed first.

Gemstone weight and composition are preset for each design. For a different stone size, contact us to confirm design compatibility, stone arrangements and pricing before production.

Images illustrate colour direction and design. Lighting and screens affect colour, and subtle differences between stones are possible. We select within the colour direction and appearance standards of this collection.

Check the stated gemstone weight, metal, jewellery size or worn length, and any offered engraving. If you have requested a different stone size, also check the agreed specification.
