The Diamond Club

What is the Diamond Club?

This is a unique Members only club for customers wishing to buy investment pieces of jewellery at half the recommended retail prices of diamond and gem set pieces.

How is the Diamond Club able to offer half price?

We source stones from various countries direct thereby cutting out any middlemen or wholesalers. By working with our suppliers, we are able to obtain any stone, any weight, any grade on approval and work on a commission basis only. This is advantageous for both our customer and ourselves as we are not having to hold stocks thus tying up our capital.

How do we know this is a genuine offer?

If you have never shopped with Hallmark before, the simple answer is you don’t. However Hallmark has been established since 1981 and with over 30 years’ experience, our Director has built up a reputation as the largest diamond merchant in the Wirral. Our customer base is loyal and extensive stretching across the North West. Trust and confidence is paramount and we would not be where we are today without customer loyalty. We endeavour to offer a personalised service to every customer and ensure that you are happy with your purchase.

Can I buy online?

Having studied the e-tail market for some time, we truly believe that when making an important and expensive purchase such as a diamond piece, it is impossible to ensure that what you see is what you get when buying online. We considered the online market but as an independent retailer, we strive to procure unique and interesting one off pieces which are not repeatable. Therefore we would always recommend that by visiting our store and taking time to understand exactly what you are buying, you will be sure of not only the correct quality, colour, clarity, cut and diamond weight that you desire but also that you are unlikely to see your piece anywhere else.

If I wanted you to make a specific piece of jewellery, can you offer this service?

Yes we can. This is something the Diamond Club excels in. Commissioned or bespoke pieces are done in conjunction with our in house jeweller.

You make an appointment at your convenience and in consultation with our jeweller, we can make anything. You may wish to remodel an existing piece or incorporate stones from another item or you may have seen something that you would like copied. We can do this.

Are there any other benefits?

  • We will clean and polish your Diamond Club piece free of charge once a year and check it for any remedial work. E.g. Ring claws, loose stones etc.
  • We supply the valuation free of charge
  • We offer a private consultation seated area in our Diamond Showroom
  • We offer complimentary refreshments
  • Exclusive preview and purchase evenings
  • Free jewellery design subject to the commission
  • Priority invitations to our Annual Ball and other charitable events

The Diamond Industry

The 4 Cs – Carat, Colour, Clarity and Cut

As diamond investment grew, it became essential to have a grading system which would be recognised throughout the world.

The Gemological Institute of America (GIA) introduced the International Diamond Grading System and the 4Cs to compare and evaluate diamonds.

caratThe carat rating for diamonds and other gemstones refers to its weight. Early gem traders would use the seeds from the carob plant to counter their scales, which is where the term carat originated.Established in 1918, the modern carat system unified the weighing system making one carat equal to 0.2grams. Carats are divided into 100 points, for example a 20 point diamond weights 0.20 carats
colourBefore the GIA introduced the Colour Grading Scale, a number of other systems were used to grade diamonds. These used alphabetical (A B & C) and numerical (both Roman and Arabic) values and the result was inconsistency and inaccuracy.Because the GIA required a unique system, they chose to start their grading system with the letter D, never previously used. This has become the international industry standard for measuring diamond colour and goes from D to Z.
clarityDiamonds all have their own unique marks, these being inclusions or surface blemishes. Both are caused in the formation of the diamond under extreme heat and pressure deep within the earth.The clarity of a diamond refers to these inclusions. The less included or blemished, the more valuable they become. Flawless diamonds are rare.The GIA system clarity grade ranges from flawless to obvious visual blemishes and can be read as FL (flawless) to VVS (very very slight) to VS (very slight). Often these blemishes are only visible with a jewellers loupe.There are a total of 11 grades of clarity going from FL D to the most marked as I1, I2, I3 (can also be listed as P1,P2,P3)
cutOf all the 4Cs, the cut of a diamond has the greatest effect on its beauty. Diamonds have unique ability to manipulate light and this can be released and maximised only by cutting and polishing the diamond to a high level of accuracy. The cut of a diamond can be split into three different attributes:Brilliance – The light reflected from a diamondFire – The dispersion of light into the colours of the spectrumScintillation – How a diamond sparkles when movedWhen looking at the cut of a diamond, various aspects are taken into consideration – the diamonds proportions, its symmetry and the polish.The depth of a diamond, called the pavilion, can greatly affect the diamonds brilliance and cutters have to be expert in balancing the retention of the stone’s weight against a pavilion depth. A well cut diamond will direct more light through the crown of the stone, thus making it more brilliant to the eye.
