How does a certification from the Gemological Institute of America affect diamond prices? 

Pink diamonds are extremely rare and can fetch high prices based on their quality. Thus, it is important to properly assess quality if the price is to be accurately determined. The world’s most trusted and known organisation is the Gemological Institute of America (GIA). The GIA’s stringent process for assessing the attributes of an individual diamond can help in determining an accurate value.

What are GIA Diamonds

What are GIA Diamonds?

GIA diamonds will have a GIA mark and a matching report number laser inscribed onto the girdle of the diamond. Although, if you have shopped for diamonds before, you will have seen diamonds that are advertised as GIA certified. Diamonds with this tag have been subjected to quality assessment by authorised GIA gemologists.

A GIA certification means that the diamond’s value adding attributes or characteristics as well as any identifying inscriptions have been properly documented and assessed by this internationally trusted grading authority. In any case, each GIA report generates an unique number that can be checked to confirm the report matches what is archived in the GIA database.

Just because a diamond is GIA certified does not immediately mean that it is top quality. Keep in mind that a GIA certification is there to merely serve as a reputable proof of quality assessment. A GIA pink diamond of good quality, however, is sure to pick up a decent price.

Not all diamonds are GIA diamonds

Besides major diamond producers, there are several other diamond grading organisations across the world.

However, while it is evident that there are inconsistencies in the gradings of clarity, colour and cut quality across the board, the GIA is recognised for applying the lowest grading when compared to other agencies’ assessments. The lower assessment may be the result of the higher standards GIA uses to assess a diamond. It pays to be aware of how another grading certificate stacks up against a GIA appraisal because you may purchase a diamond that has inflated gradings which will affect its investment and resale price.

As a grading agency, the GIA can be commissioned to produce a Colored Diamond Grading Report which provides the diamond’s colour grade, colour origin, whether the diamond is natural or treated, carat weight, clarity, shape and cutting style, and a plotted diagram of inclusions with an optional coloured image of the diamond.

A GIA certificate is often used in conjunction with an Australian Pink Diamonds Gem Identification Document to provide an internationally recognised comparison to non-Australian coloured diamonds.

Natural or Laboratory-grown?

The GIA has been grading laboratory-grown diamonds for more than a decade. While there are small differences between lab-grown and natural diamonds, the former is usually more affordable. This is because they are faster to produce, but the demand is lower as lab-grown diamonds have a smaller resale value.

GIA certified laboratory-grown pink diamonds may still fetch high prices, based on clarity, albeit lower than that of rarer high clarity natural pinks. Think carefully about why you want to buy one of these before you purchase one. As more are produced the value will decrease, so they are not as good an investment as natural pink diamonds.

GIA diamonds don’t necessarily cost more

Some people associate GIA diamonds with a big price tag, but that is not always the case. As mentioned, a certification does not denote a high quality; it only means that its quality was assessed by the GIA. However, a GIA certification may be used to value a good quality pink diamond higher based on the world wide reputation the GIA maintains.

The GIA has additional grading standards for assessing the quality of a coloured diamond. The basis for these are the 4Cs of diamond quality. Standing for colour, clarity, carat weight, and cut, how they affect a pink diamond’s certification is examined below:

Colour

Pink diamonds come in a wide variety of shades, from slight blushes through to strikingly vivid pinks including the exceptional rare red. The GIA uses colour as one of the main factors for assessing a pink diamond’s value. Specifically, there are three criteria that a diamond is assessed by – hue, tone and saturation.

Hue: The GIA has established a known spectrum of colours in which diamonds usually present. For colourless diamonds, the absence of colour is graded from colourless, classed ‘D’ as the most valuable down to ‘Z’ for diamonds with a noticeable yellowish-brownish colour.

For fancy coloured diamonds, an exceptional presence of colour is graded. Typical fancy colour names are blue, deep yellow, orange, red, green, pink, purple, and brown. A secondary hue may also be present affecting the stone’s grading and these diamonds are named with the secondary hue listed first like this : purplish red.

Tone: Diamond tone refers to the darkness of a diamond’s colour. A dark tone is valued higher than a light or pale one.

Saturation:  Saturation refers to the distribution of any colouration throughout a diamond. The strength of a diamond’s colouration can be seen more easily with a good saturation value.

Terms used to describe the tone and saturation on a GIA Coloured Diamond Grading Report are Fancy, Deep, Intense, Vivid, Light, Very Light, Faint and Pale. The colour distribution is graded ‘Even’ or ‘Uneven’ depending on which 50%

Pink diamonds with good combinations of the colour criteria, of course, will be the priciest ones. The GIA assesses each of these criteria carefully to give an accurate report.

Clarity

GIA gemologists will identify the clarity of a diamond under 10x magnification and determine the characteristics of inclusions which are then plotted onto a diagram of the diamond, adding value to the certificate as a verification tool.

Flawless natural pink diamonds are extremely rare, commanding the highest prices. However, with value placed heavily on the colour intensity of a pink diamond, those with few or relatively invisible inclusions can still command high prices.

Carat Weight

A GIA expert gemologist uses an electronic micro-balance scale to find the weight of a diamond to the nearest ten-thousands of a carat, in addition to determining the diamond’s measurements, proportions and facet angles using an optical measuring device.

Pink diamonds are already rare, to begin with. However, ones with a high carat weight after cutting are even more so. A pink diamond can reach prices of one million dollars per carat.

Cut

A diamond’s cut plays a crucial role in its beauty. The number, size and angle of a diamond’s facets allow light to reflect and refract in different ways. A well planned cut allows light to give a diamond a more intense level of brightness, fire and scintillation. Excellent cuts allow a diamond to appear more luminous, whereas a poorly-cut one may lack brilliance.

GIA’s Excellent to Poor Cut Diamond Grading System for Round Brilliant diamonds uses computer modelling to assess a colourless diamond’s sparkle and interplay with light. In colour grading, where the value is based on the colour intensity and size of the gem, the GIA’s Colored Diamond Grading Report describes the shape and cutting style, maps the proportions and facets, and grades the polish, symmetry and fluorescence of the diamond instead.

GIA has the strictest standards for grading diamonds. If the GIA reports your pink diamond as an excellent polish quality or displays a clarity grade of VVS2, then it is likely to be indisputable. The GIA certification acts significantly on your behalf as it can be used to verify the value of a quality diamond you are about to purchase and it can add weight to the valuation for your  nominated insurance broker or when you are ready to sell your investment.
