Diamond Guide – How To Choose A Diamond

It is easy to become overwhelmed when working out how to choose a diamond and this diamond guide will assist you to make the choices that bets fit your budget and expectations. Unless you have an unlimited budget then understanding what you can expect from compromises in each aspect of the stone will help you to choose the perfect diamond for you or your loved one.

Diamond Variables

What diamond shape is right for you?

best diamond cutsDiamonds come in many shapes and often the shape is a matter of personal preference. It is important to discuss the shape as this will determine the choices available to you. The next thing to consider is the size (weight) known as the caret. The person receiving the diamond will often have a diamond of a certain size as their preference, often a 1 caret stone.

Diamond Size – which size is best for you?

Your budget determines the size of the diamond you choose. However if you lower your expectations in the all or any of the 4 C’s (caret, colour, clarity and cut) your budget will stretch further and you can have a larger stone. The larger the diamond the rarer it is and the value increases disproportionately as the size the increases. Caret weight or size is only one of the factors that determine the ultimate price the diamond is worth.  To get a better understanding lets look at the other factors the influence price and value.

Diamond Clarity – what level of clarity is best for you?

diamond shapes and cutsThe clarity of a diamond relates to the number or size of any flaws (inclusions) in the diamond. There are a number of grades of clarity ranging from Internally Flawless to SI3. Many inclusions are not visible to the naked eye and as such have little impact on the appearance of the diamond but a positive impact on cost. If you are looking to maximise caret size then clarity is probably the area that has least visible impact on the naked eye appearance of the diamond. If you choose a diamond around 1 caret then a clarity rating of SI1 will have no impact on appearance, whereas a 2 caret stone you would probably need a rating VS2 to achieve the same look. Each stone is different and many people are willing to compromise on clarity to have the caret size they want. It’s up to you there is no right or wrong.

Diamond Colour – what level of colour is best for you?

This is still the case with white diamonds, but recently coloured diamonds have become extremely valuable due to their very limited supply and collectability. Argyle Coloured Diamonds Review. The cost and value of white diamonds varies greatly, a grade D (highest grade and colourless will be significantly more than a Grade J which would have a yellow tinge to the diamond. However if this grade were set in a yellow gold ring the slight yellow colour would blend into the gold and the stone would appear whiter to the naked eye. This is a way to increase caret size if that is your objective.

Diamond Cut – the most important C of the 4C’s

Diamonds come in many shapes and sizes and the cut determines the level of sparkle in the stone. There are various standards relating to cut such as GIA. Diamonds graded by companies like GIA provide a certificate that details the cut of the stone, including clarity, colour, caret and cut. The various grades of cut such as Excellent, Very Good, Fair, Poor are not uniform between grading companies, so certificates issued by GIA and EGL are the most reliable and accurate. An excellent cut diamond will reflect more the most light and therefore sparkle. A poorly cut stone will appear dull even if it has high clarity and colour. Cut takes into consideration factors (such as polish, symmetry, table %, depth %, culet size, girdle width, etc), the proportions of which determine the grading.

Carat Weight Buying Tips

Search for diamonds that are just under standard caret weights such as 1/2 ct. 3/4 ct., 1 ct., etc. A diamond of say .90 caret will often be sold at discount to the 1.00 caret price as many people want the exact standard sized stones. To the untrained eye both stones would appear almost identical.

Shape Buying Tips

Round diamonds are a traditional engagement ring shape and never go out of fashion.  They tend of have more brilliance and scintillation than other shapes and can be set in a variety of ring settings, in yellow or white gold and platinum. If budget is the prime consideration and a diamond under .75 carats is a budget necessity, consider a marquise cut. The Marquise cut due to its elongated cut appears larger than other shapes of equal carat weight.

Colour Buying Tips

Diamond SizeDiamonds with more facets reflect more light, they are better than other shapes at disguising colour. To maximise the  value of colour consider round, princess or emerald or asscher cuts to get the best value for money colour. As an example a H colour diamond could have the same appearance as a D coloured stone when set in a ring in general outdoor conditions. The smaller the diamond the greater the chance it will look as a colourless diamond.

 

Clarity Buying Tips

As previously mentioned, clarity is probably the area where the greatest compromise can be made, without sacrificing the integrity of your diamond. A clarity rating of SI1 usually means any inclusions are not visible and you can exchange for a higher cut or colour grade. Depending on the colour and cut it is possible to have a beautiful, lively diamond with imperfections detectable only upon close inspection.
