Product Information

  • Where possible we use high quality diamonds of a D-H colour and FL-SI2 Clarity, a minimum of Faint/Slight fluorescence and a minimum of good cut, polish and symmetry. a small selection of jewellery may be slightly lower quality than this.
  • The alloys we sell and work with are: Platinum, 18ct White/Yellow/Rose, 9ct White/Yellow/Rose, Palladium and Silver. However a small selection of jewellery is 14k/15k. If an item states gold plated, this is gold plating on 925 silver.
  • Our white gold products are rhodium plated to the industry standard. The rhodium does eventually start to wear off but they can be re-rhodium plated. Occupational and lifestyle wear, as well as chemicals such as chlorine can all shorten the life of rhodium plating but a ring for example, should last at least six months to a year.
  • Many designs can be made to order using a variety of coloured precious and semi-precious gemstones. All our coloured gemstones are sourced from long established reputable companies worldwide.
  • Our ladies bracelets are generally made to an average length between 7"-8". If you require a different length please contact us. We may be able to adjust certain designs. Contact us at info@avantijewellers.co.uk 
  • Our pre-owned watches are under guarantee with us for one year from purchase.
