Buying Guides | Our easy to follow diamond buying guide will solve your any queries that you have related to diamonds like certifications, designs, historic values and more.


Perhaps the 5th ‘C’ when purchasing a diamond is the CERTIFICATE or diamond report. This important document validates the diamond’s characteristics. A diamond certificate from a ‘no name’ laboratory or jewellery shop is not worth the paper it’s written on, insist on quality grading documents. The world’s foremost diamond report and the leaders in diamond research are the inventors of the 4C’s; the GIA (Gemological Institute of America). There are other laboratories that also use the GIA methods and/or have a very good reputation, they are:

GIA Certification GIA (Gemological Institute of America)
mini__ags AGS (American Gemological Society)
mini__hrd HRD (Antwerp World Diamond Centre)
mini__igi IGI (International Gemological Institute)
mini__egl EGL (European Gemological Laboratory)    DG no longer sells EGL certificiated diamonds

The diamond grading laboratories listed above are the largest, probably the strictest and certainly the most well known of the international gemological centres. There are subtle differences in grading techniques but the overall consensus is usually very close between these institutions. Any other diamond report may warrant further analysis of the laboratories processes and ability to grade in a consistent and unbiased manner that represents a true and fair diamond report. Because the diamond certificate reports the characteristics we have discussed above its vital and imperative it comes from a reputable source. A diamond valuation or appraisal is significantly different from a diamond report or certificate and should not be confused.

ALWAYS insist on a diamond certificate from a major laboratory!

Remember that when buying a diamond there are many characteristics that need to be balanced and reviewed in order to buy quality within your budget.

Every certificate from any lab. will carry its own disclaimer, this from an E.G.L certificate is typical:

‘This examination has been carried out using the current gemological procedures of E.G.L.
The report or seal expresses an opinion at the time of inspection of the stone, not a guarantee, valuation or appraisal. No representation or warranties as to accuracy are made. Diamond grading is not a science; It represents only the best professional opinion of this company [the EGL], which chooses its own standards or norms. A+/- 20% error of judgement is scientifically possible. E.G.L. is expressly held harmless by customers including, but without limitation for any claims or actions that may arise out of negligence in connection with preparation of this laboratory report or seal, or actions based upon the customer’s use of the certificate or seal’ stresses the following poignant points from this:-

  1. Diamond grading is not an exact science
  2. A certificate is not a guarantee, valuation or appraisal – It’s an assurance
  3. A certificate expresses a single opinion at the time of inspection of the stone
  4. One man’s VS is the next man’s Si
  5. Our advice, know where you are and insist on a certificate from the stricter labs and the GIA gets our strongest endorsement

Princess Cut. A Distinctive Choice

Though the Princess Cut is widely traced back to 1961 when London diamond cutter, Arpad Nagy, created a square cut that looked to compound the brilliance of the round brilliant cut, it was later in 1971, when the Barion Cut was renamed the Princess Cut, and later still in 1979 that the Quadrillion Cut was also merged into the Princess Cut approach.

The Princess cut is now second only to the round brilliant cut in popularity and is highly desirable and popular in pendants and engagement and eternity rings. The Princess cut weighs more than the round brilliant cut but there is a higher percentage of rough diamond. This reduces the price of the item but the diamond itself is distinctive and stands out.

The Princess Cut is an inverted pyramid shape, with 4 bevelled sides and enjoys the same high level of light dispersal as the round brilliant cut with facet levels of either 76 or 58. It’s square form also reduces the chances of shadowing and the bow tie effect and maximises the available light.

Another reason for its high popularity is that the Princess Cut creates an elongation to the finger, creating elegance and grace. Its distinctive style is perfect for non-traditional rings and items and, also for personalised designs and appears in many forms, other than wedding rings.

To talk to an expert about the most appropriate cut for you and possible design options speak to DiamondGeezer who will provide a series of Princess Cut inspirations. All designs are bespoke and rings are created by cutters with huge experience. The 30 day money back, or exchange, or tweaking service, is available on all items including personalised design so you can buy with full confidence.

All of DG Princess Cut diamonds are available in a range of styles, settings and pieces including pendants, necklaces and bracelets.

Wedding Ring

A wedding ring, the symbol of eternity and ever-lasting love.. If you buy the right rings that is. Of course wedding rings will be a beautiful symbol of the happiest day of a couples life & the life they will share together no matter what the ring, but it can’t just be any old metal band thrown onto the finger. Think about it this way, the wedding budget is running low & you’ve left the wedding rings until last minute so you just run into your local jeweller and get the cheapest, easiest ring or rings you can find, you wake up 2 years later & the very symbol of your “ever-lasting” love has snapped. Not the ideal scenario really, is it?

So, lets rewind to when you had a healthy wedding budget & months of planning ahead of you. You can see beautiful flowers, cute little bridesmaids, an amazing wedding dress and wedding rings, one of the most important parts of the best day of a couples life. Next, you search around for the best wedding rings you can possibly find & afford to really symbolise that your love for each other is never-ending with no snapping or breaking or getting worn-out around the edges.

Now you’re wondering how you’ll know which metal to choose for your wedding ring, aren’t you? With a choice of 9 or 18 carat white, yellow or rose gold, palladium & platinum, it can get quite difficult to know the difference between these metals. Choosing gold for your wedding ring is one of the cheaper options, although gold wears in time, meaning it will end up becoming thinner and thinner making it easier to eventually break. When buying white gold you should keep in mind that it was originally yellow gold, rhodium plated & then given the name white gold. This means that white gold is harder to maintain and requires extra care. Palladium is part of the platinum family, making it a very strong and reliable metal. Palladium has a pure, crisp white colour that will last forever. Then we have platinum, pure, rare and ever-lasting.. Remind you of anything? Platinum even grows stronger over time, meaning no breakages or worry that you will eventually have to replace your wedding ring.

With all of the above in mind, the choosing of your wedding ring should no longer feel a chore. It’s simple really, your wedding rings are the one thing that will be seen for a lifetime as the very symbol of your commitment to a person. Wedding rings really are one of the most simple & beautiful possessions you can own. Let’s be honest, nothing beats true love, does it?


Asscher Cut Diamonds

The media has played a huge role in the increasing popularity of the Asscher Cut Diamond. Since the early episodes of US television hit Sex and the City, and celebrity engagements, such as Kate Hudson, the Asscher Cut diamond is now hugely back in fashion.

The Asscher Cut History

The Asscher Cut was produced in 1902 by the Asscher Brothers in Amsterdam and is a 58 faceted Cut. It was the first signature cut to be patented. The Royal Asscher Company was founded in 1954 and is still regarded as one of the world’s premier diamond cutters with a client list that includes royalty and A-list celebrities.
The Asscher cut is a stepped square cut, like the emerald cut, and has cropped corners. It is designed to focus the eye on the diamond, not the setting. Originally the designs matched the art deco style of pre First World War Europe but the appeal still lasts a century later and fulfils a retro demand for beautiful diamonds in a solid square format.

High Fashion

The current fashion appeal seems to centre on the focus of the diamond and there is a retro feel to the cut. Simply put the diamond is the star, ensuring the piece is not too feminine or fancy. Though the retro art deco them is often copied the Asscher cut is widely regarded as the setting that encapsulated the art deco period of grace and elegance.

The Perfect Jeweller has a range of Asscher cut diamonds and offer 30 day money back guarantee. With our various accreditations with the British Jewellers Association, Assay Assured and Trust Pilot mean that you know you are dealing with a genuine company.
