In response to jeweller JannPaul, diamonds should not every other luxurious branded good akin to a Lamborghini or a Louis Vuitton bag, that are instantly recognisable.

Between a “branded” and “non-branded” diamond, there are a lot of elements that have an effect on a diamond’s magnificence — rather more than what you suppose (the 4Cs, which might be defined under).

In actual fact, strolling right into a branded diamond store doesn’t assure you a stunning diamond.

To assist its clients make the perfect diamond determination, JannPaul prides itself on offering schooling — regardless that this isn’t a norm within the jewelry trade.

Right here’s how JannPaul guides its clients all through the diamond-buying course of (detailed explanations included right here):

What’s a GIA Certificates and the way do I learn it?

When a gemological laboratory has assessed the standard of a diamond, it points a certificates with the diamond’s detailed specs. There are a number of well-known gemological labs — GIA, AGS, IGI, EGL, GSI, and HRD — with GIA (Gemological Institute of America) and AGS (American Gem Society) being 2 of the strictest, dependable and most recognised on this planet.

And sure, this does matter, as a result of the lab’s evaluation will have an effect on how the diamond is priced. Additionally, the stricter a lab is, the extra correct the diamond’s paper specs might be.

Right here’s the right way to learn this pattern GIA cert:

April 30, 2018 — The date the diamond was licensed by the lab.

GIA Report Quantity — This can be a distinctive serial variety of your diamond that’s laser-inscribed in your diamond’s girdle.

Form and Reducing Model — The form is fairly simple, and the reducing model refers back to the side sample.

Measurements — This reveals the size to width (longest to shortest diameter) and depth of the diamond. By dividing the size to width, you’ll get a ratio. 

Now transferring on to the 4Cs on the GIA cert, that are defined in additional element under:

Carat Weight — How heavy the diamond is, with 1 carat = 0.2 grams.

Color Grade — The physique tone of the diamond, finest analysed from the pavilion facet of the diamond (diamond flat-side down). The decrease the color grade, the hotter the tone of the diamond. For instance, E is colourless and H has a really mild tint.

This picture above reveals G Color graded diamonds, in numerous hues. Underneath typical jewelry retailer lighting, it’s virtually inconceivable to see any distinction as direct lights would masks the hue colors. Nevertheless, once you view the diamonds below white mild (eg. workplace lights, out of doors cloudy daylight, and so on), these hue colors are very apparent.

JannPaul solely accepts diamonds which have a yellow hue, as it’s the least apparent color amongst the others.

Readability Grade — This refers back to the inclusions (inside) and blemishes (floor) of the diamond. The readability grade begins from flawless and goes to VVS (very, very barely included), VS, SI (barely included) and so forth. The GIA cert additionally reveals the diamond’s readability traits, AKA the kind of inclusions.

These 2 diamonds have the identical Readability grade. Nevertheless, the diamond on the left has cloud inclusions, which causes the diamond to look milky.

Minimize Grade — This refers to a diamond’s proportion.

Nevertheless, when you convey the diamond outside away from these jewelry lights or below white mild (workplace mild), the true look of the diamond is revealed. A poor performing diamond will seem darker, duller and fewer sensible below these reasonable on a regular basis lighting environments. So as to keep away from poor performing diamonds, you could verify the diamond’s proportions and lightweight efficiency.

So as to verify the proportions of a diamond, a free and helpful on-line device is the HCA Instrument (Holloway Minimize Adviser). Key within the values on the diamond’s GIA cert to acquire a ultimate rating. The rating will vary from 0.4 to 10, however the decrease the rating, the higher the diamond’s mild efficiency. To be secure, JannPaul recommends a HCA rating of 1.4 or under.

Nevertheless, JannPaul cautions that the HCA device ought to solely be used as a rejection device to weed out diamonds of poor proportions.

Whereas a excessive HCA rating implies that a diamond has poorer mild efficiency, a low HCA rating could not essentially assure {that a} diamond has good mild efficiency. It’s because the Crown and Pavilion angles on the certificates are solely common values.

For instance, a diamond could have crown angles of 33°, 35°, 35.2°, and get a median worth of 34°. As well as, the HCA device solely takes under consideration 17 out of a diamond’s 57 aspects. Therefore, a low HCA rating doesn’t at all times translate to a good-performing diamond.

As soon as a diamond with a low HCA rating (good proportions) is discovered, the subsequent step is to verify its mild efficiency. That is the largest think about figuring out a diamond’s brilliance, fireplace and scintillation.

The ASET Scope, which stands for Angular Spectrum Analysis Instrument, measures the sunshine return of a diamond. This helps us analyse the diamond’s “fireplace” (the bursts of rainbow-coloured mild when the gem is considered below a direct mild supply) in addition to the quantity of scintillation (the quantity of sparkles and flashes when the diamond is moved).

Different objects in your GIA cert to have a look at embody Polish (how easy every side of the diamond is) and Symmetry (how exact every side aligns and intersects with each other, which may have an effect on mild efficiency).

For the latter, whereas a diamond could have Glorious Symmetry, the Hearts & Arrows sample might not be optically symmetrical. So you could verify your diamond below the Hearts and Arrows scope.

There’s additionally Fluorescence, which may have an effect on how the diamond appears to be like below UV mild or daylight. An excessive amount of of it might probably make your diamond seem chalky/milky, boring or have an off-colour tint. So most individuals will go for a diamond with no fluorescence.

The final rule of thumb is that diamonds with the identical GIA certs and triple Glorious scores usually price about the identical in most jewelry shops.

Seeing is believing — don’t simply depend on the GIA cert

The GIA cert nonetheless stays an necessary start line for shortlisting your very best diamond — no less than the place value and baseline specs are involved. The following step is to make use of instruments and your eyes to match your shortlisted rocks, below several types of lighting.

For instance, JannPaul has accomplished among the shortlisting for its clients — its Tremendous Splendid Minimize diamonds are actually the creme de la creme of diamonds with GIA certs that present a triple Glorious rating.

Casey Lai, a co-founder of JannPaul, tells us extra: “The Tremendous Splendid Minimize time period, launched in Asia by JannPaul, upholds the strictest normal of diamond cuts on this planet. Nevertheless, it’s a closely misused time period as of late.

“When JP began 10 yrs in the past, this normal of diamonds was by no means seen out there earlier than and it took the trade abruptly. Over time, many jewellers have misused and abused the time period to promote low-quality diamonds as their very own ‘Tremendous Splendid Minimize’.

“Sadly, the diamond trade will not be regulated, permitting any distributors to loosely label their items. As much as as we speak, we proceed to teach our purchasers to allow them to make knowledgeable selections and never be misled.”
