Money saving tips for buying a diamond ring

When it comes to buying a diamond ring, there are a few tips which can save you some money.  We share them with you below:

(i) cluster rings

A cluster diamond ring can give the appearance of a larger diamond but it is in fact a cluster of small diamonds. A cluster of say four 0.25 carat each princess cut diamonds in the shape of one 1.0 carat princess cut diamond is significantly less expensive than one 1.0 carat princess cut diamond – with a saving of up to 50%.

(ii) halo rings
Usually, a halo makes the centre stone look larger – for example, a 0.50 carat diamond in a vintage style halo setting can give the appearance of a 1.0 carat or even a 1.50 carat diamond as the extra bling makes the diamond stand out to a greater extent.

(iii) white gold

White gold is a good alternative to platinum and it is also less expensive. Platinum can go dull over time. White gold is easier to work with as a metal as it has a lower melting point (useful if you need the ring resized at a later date).

(iv) Buy the wedding ring at same time

If you purchase the wedding band at the same time as the engagement ring, most jewellers (we certainly do) give a good discount. If you also get the gents wedding band at the same time you can make additional savings.  You also ensure that you find the perfect matching wedding ring (same width, same metal, same style etc). These concerns are not always obvious when you shop for you engagement ring but are important concerns when looking for your wedding band.

(v) Alternatives to diamonds
The second most popular alternative to a diamond is a sapphire.  These are less expensive than diamonds and similar to diamonds, come in a range of quality.  We have access to thousands of sapphires for you to view in our Dublin office.


(vi) Choose your 4 C’s wisely

The more rare a diamonsd is, the more valuable it is.  For example, the rarest colour is ‘D’ colour. A ‘G’ colour for example looks very similar to a ‘D’ and can be up to 15% less expensive. Placing a ‘D’ and a ‘G’ colour diamond side by side, it is difficult to see any difference with the naked eye. However, placing a D diamond with a ‘J’ colour diamond would be more obvious with the naked eye as the ‘J’ colour may appear less white in comparison to the ‘D’ colour. A J diamond on its own can look very pretty and would look white – only if it was directly compared to a whiter diamond would it become obvious.

Clarity is another area where money can be saved. A ‘VVS1’ diamond can be very expensive with a ‘Vs2’ diamond up to 20% less expensive.  To the naked eye, these diamonds can look identical with the inclusions only noticeable under a microscope.

Carat size is another area where you can save a bit of money on a diamond. A 0.90 carat diamond can be up to 20% less expensive than a 1.0 carat diamond and again, to the naked eye they can look identical. We specialise in locating diamonds with a good spread which appear larger than they are, while ensuring the diamond cut is very good or excellent. The ‘magic numbers’ as they are called are the carat weights which cause the price to shoot up. For example a 0.50 carat; 0.75 carats; 1.0 carat; 1.5 carat; 2.0 carat etc.  A diamond just under one of these magic numbers can result in good savings.

(vii) Jewellers discount range

Most jewellers have a range of rings which they have in stock a long time and they will sell at a discounted price. We at Perfect Ring have a small selection of rings which we have in stock for a long time and we are willing to sell these at cost price. These may be styles that for example we purchased a few years ago and the style of the ring is quite unusual or unique and might suit the tastes of a smaller number of clients. All jewellers would have a range of in stock for a relatively long time which they would sell at a discounted price – they may not be as open about it however!

What metal is best?

What metal is best? When it comes to precious metals, each metal has their own advantages. For engagement rings, we would recommend 18k white gold or platinum or 18k yellow gold.  Anything less than 18k is generally not used in Europe as the metal is not as strong.

For gents wedding rings, we think palladium is a cheap alternative to platinum and 18k white gold.

Diamond Information

When buying a diamond ring, it is advisable to do a bit of research before you start looking at rings.  This will ensure that you are fully aware of the main points when it comes to viewing a diamond and it also ensures that you get the best diamond to suit your budget.

We at Perfect Ring meet people on a daily basis and assist them in understanding diamonds – we are more than happy to assist you in this process also.

For those who would like more information in relation to diamonds, we would advise the following:

– become familiar with the 4 C’s of diamonds
There are many articles and you-tube videos relating to the 4 C’s – I explain them briefly below.

1. Carat
The diamond carat relates to the weight of a diamond. Broadly speaking, the larger the carat, the bigger the diamond, however this is a bit over simplified. It is possible to get a diamond with a larger spread, in other words, it looks larger than it actually is. It is possible to get a 0.90 carat diamond which looks larger than a 1.0 carat diamond simply because the spread of the 0.90 carat diamond is larger.  We specialise in identifying excellent cut diamonds which appear larger then they are – our access to over 250,000 diamonds facilitates us to do this.

2. Colour

The more white a diamond is, the rarer it is and the more expensive it is also. The purest diamond is called a ‘D’ colour. The scale runs from D to Z where Z is heavily tinted yellow. We would recommend staying in the range D – I colour and anything below a colour I would result in a tint of yellow in your diamond, which we would not recommend. Most diamonds are in the F – H colour range with very little difference in the look between an F and a H coloured diamond.

3. Clarity
Most diamonds contain small markings inside the diamond called inclusions. Most cannot be seen with the naked eye. The range is from IF (Internally Flawless) to I1 (medium to large blemishes)
Scale of inclusions is below.
Similar to the diamond colour, the further right your go on this scale, the less expensive the diamond.  We would recommend not going below a Si2 inclusion diamond as anything below this may become noticeable with the naked eye.

4. Cut
Diamond cut is one of the most important features of a diamond. The cut relates to the sparkle of a diamond. A poor cut diamond will not have brilliance and fire in it.  We specialise in only providing diamonds which are a very good to an excellent cut as we believe that a diamond should capture light and sparkle in all its glory. Diamond cut and diamond shape are two different things – the cut has an impact on the sparkle, shape is just the shape the diamond was designed.

5. Cost
We like to add a bit to the 4 C’s and the fifth C is cost.
As we have access to over 250,000 diamonds and are managed by a diamond dealer, we have seen the mark up shops place on diamonds.  We encourage you to shop around for your diamond – we sell at wholesale prices and we are confident that we will be unbeaten on both price and quality.


6. Certificate
All of our diamonds are certified by the worlds leading diamond grading bodies (GIA; HRD; IGI). Each ring we sell also has an independent valuation certificate.  We believe in transparency and honesty at all times. We would also advise people against jewellers who ‘self certify’ their own rings as the details may not be accurate.


7. Confidence

We would encourage people to buy from a reputable jeweller and one who offers a complete exchange on goods (like us at Perfect Ring).  Given our large range and access of diamonds, if you surprise your loved one with a ring which is not to their taste, we can exchange it for you.  All resizing is done in our Dublin City centre workshop – many ‘appointment only’ jewellers outsource their work to the UK, however we believe in quality service and everything we do is with you in mind,which is why we keep everything local. Also any repairs that may be required are done within 24 hours.

For more information we recommend looking at the GIA website which has a lot of useful information about diamonds and gemstones and also their ‘frequently asked questions’ section of their website which is at
