• Where possible we use high quality diamonds of D-H colour and FL-SI2 Clarity, a minimum of Faint/Slight fluorescence (in most cases - no fluorescence) and a minimum of good cut, polish and symmetry. A small selection of jewellery may be slightly lower quality than this. You can see more diamond information below

• 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 pre-owned 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 and hand sanitiser can all shorten the life of rhodium plating.

• 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 on time keeping unless stated otherwise.

Diamonds

The carbon based mineral is the hardest of all known substances (Mohs hardness scale 10) and exist in a variety of colours. White diamonds are graded by colour, clarity, cut, polish, symmetry and fluorescence. Diamond sizes are weighed in carats. 

Shape (also known as cut)

Our most popular diamond shapes are round brilliant cut and princess cut diamonds. However many more cuts are available including Asscher, Emerald, Oval, Marquise, Pear, Cushion, Radiant and Baguette.

Colour

Colour grade mainly range from D (exceptional white) to M (tinted yellow colour). D, E and F are the collection colours which are graded as colourless.

Clarity

Natural imperfections and inclusion within the diamond. These are graded from Flawless down to Pique.

Cut

The cut is the proportions and angles of the finished diamond. This is graded from Excellent to Poor

Polish

The finish of the surface of diamond.This is graded from Excellent to Poor. Here are just a few examples:

Symmetry

This is accuracy of which the diamonds alignment and facets to perfect proportions. This is graded from Excellent to Poor. Here are a few examples:

Fluorescence

A blue colour which can be omitted by the diamond under ultra violet light. This is graded from Nil Fluorescence to Very Strong. (a stronger fluorescence can give the diamond a milky appearance in daylight)

Diamond Certificates

We only recommend the top three diamond certificates which are the most accurate. These are the GIA, HRD and IGI.

How Long Does It Take For A Bespoke Piece Of Jewellery?

We may need to get in a selection of loose stones in for you to view etc. Once a you have confirmed a proceed on a design/stones etc it is usually around 4-6 weeks unless there is a large number of stones to hand set then it could be up to 8-10 weeks. If the item is needed for a specific date we will always try to work within realistic time-scales.

What If I Ordered The Wrong Ring Size?

• Platinum and gold will usually size within three sizes depending on the design. We may need to remake the ring if it is not possible to re-size.
• Palladium doesn't size easily but most designs will adjust a couple of sizes.
• Titanium is an extremely hard metal and therefore cannot be sized more than one size. You would need to return the ring to us unworn for us to exchange the ring. This would take an additional three weeks as our titanium rings are made to order. Unfortunately we cannot exchange rings which have been personalised with engraving. 
• Silver can sometimes be sized depending on the type of stone and how it is set. As silver is such a good conductor of heat the stone can be damaged in the sizing process. It is best to return the ring back to us unworn and we can exchange this for a different finger size.

How Do I Care For My Gemstones?

Diamond, Sapphire, rubies and aquamarine are harder stones so it is safe to use warm soapy water. 

Extra care must be taken with gemstones such as Emerald, Tanzanite, Opal, Pearl, Blue John and Mother of Pearl avoiding chemicals and heat as these are some of the more delicate gemstones.

We recommend professional cleaning for all gemstones.

What if I only know the finger size which is not a UK size?

Diamond Here we have a ring size conversion chart from other countries such as the United States, Europe, and Asia. We always recommend getting your finger measured by a professional in the UK if possible as this chart is only a guide.
