There are lots of opinions within the rings industry approximately which grading lab is nice when deciding on a diamond. The hassle with those reviews is that they’re usually jaded because the person/business giving you the opinion desires to promote you their diamond. Their opinion on which grading lab is pleasant is determined by using what lab has graded their diamond, how handy is that? If they personal a diamond certified by way of EGL then they inform you that EGL is high-quality, in the event that they have any other diamond owned by GIA then GIA is best. These are biased evaluations and also you need to be very cautious as to how a lot weight is given to them at some point of your selection making procedure. 對戒
How are diamonds certified?
The “Big Three” grading laboratories as I like to call them have comparable procedures for certifying diamonds. This technique includes several Graduate Gemologists independently assessing and agreeing on the colour, readability, and carat weight of the diamond. This enables lessen the opportunity for human error when determining the very last grade for the diamond, although it does not get rid of it. You need to bear in mind the indisputable reality that there may be no actual science in the back of diamond grading. I recognize the grading systems sound respectable and technological know-how like but they’re actually are not. Ponder this declaration for a moment, “No diamonds are precisely alike.” With that being stated, how should two different diamonds which are not precisely alike be graded precisely alike? In fact they cannot be.
The different crucial fact is that the final excellent grades are selections or evaluations not scientific calculations. So if they’re evaluations and each diamond is graded by different labs and exceptional graders then how ought to there be any consistency? Truth be recognized, grading labs have a hard time with that, irrespective of which lab you talking approximately. Let’s say for example, that you send a diamond to GIA for certification and it comes returned carat weight – .50ct, clarity-SI2, Color-H. Then, you throw away the certification and send the diamond again for a 2d grading as though it were in no way graded earlier than. The danger of it coming again SI2, H again is probably 80% and 20% that it’s going to come back one of a kind. So the grading and certification method is incredibly incorrect to begin with. If you can’t get one grading lab to always consider its own grades, how ought to you expect other labs to accept as true with any other? Again, there’s no easy solution to that question and as an enterprise we nevertheless do not have it figured out.
From a customer point of view the first-class method to shopping for a diamond is to use your quality judgment. Read the grading report from anything lab certified the diamond and observe each the diamond and the certification. Use the certification more often than not of thumb or a starting point, don’t use it as the quit all be all. Learn how the grading device works after which evaluate diamonds facet by aspect under the microscope and determine for yourself which diamond looks better.
GIA, EGL, AGS, GIA – Gemological Institute of America EGL – European Gemological Laboratory AGS – American Gem Society
Recently, GIA seems to have the first-rate reputation for grading diamonds as it should be. I venture this due to the fact I’ve seen and as compared many diamonds from all three labs and witnessed inaccuracies in GIA grades as often as EGL and AGS. I accept as true with that GIA, EGL, and AGS are the three best solutions for buying diamonds but, I don’t feel one is better than the other. One exciting reality is that you will pay 15% greater (on common) for a diamond licensed by using GIA due to the fact their recognition seems better than different labs. The hassle with that is that EGL and AGS are perfectly capable of grading a diamond as appropriately as GIA, and commonly do. So if that is the case, then why might pay extra for a GIA licensed diamond that has the equal grade as an EGL or AGS diamond? The solution is which you should not! One of the first-class offers in the rings industry is a diamond certified by means of EGL; that is because a few jewelers anticipate that EGL is not graded as conservatively as a GIA. In the give up many jewelers price an EGL licensed diamond at less than GIA or AGS stones. This I agree with is a mistake due to the fact in my experience the grading for all 3 labs is similar. For a client although, shopping an EGL licensed diamond is an extremely good possibility to buy a properly graded diamond for tons less than you have to. You can research extra about diamond certifications at licensed diamonds.
AGS has end up very terrific for his or her understanding approximately cut and grading a diamond for its potential light performance. Most of what the jewellery industry makes use of to decide if a diamond is optimized for brilliance is based on AGS’s studies. If a jeweler suspects that a diamond is reduce thoroughly then he can also send the diamond to AGS for certification. If you’re seeking out a diamond with a totally excessive cut grade you need to recollect looking at diamonds which have been certified via AGS.
Get more involved within the diamond buying manner and recognize how the 4C’s paintings, now not just what it stands for. Ask to use a jeweler’s loupe (eye piece) or a microscope to see the diamond underneath magnification. When searching on the diamond underneath magnification have a look at the inclusions for every grade you are thinking about then evaluate them side through facet to determine if one seems better than the other. For example, let’s consider you are looking at SI1 diamonds – one is an authorized by way of EGL and the other GIA. After comparing them, you make a decision that the diamonds appearance similar but the EGL diamond is 15% less in charge. Who cares what lab licensed them! Just due to the fact a few jewelers suppose that GIA is a higher grading lab would not make the diamond licensed by means of GIA higher. The grading labs don’t make the diamonds, they genuinely grade them, a diamond is not made better by way of its certification. A certification is simply a bit of paper; you cannot positioned a bit of paper in a hoop and propose. If one diamond appears higher than another it probably is, no matter the grade or what lab assigned it. So in this example the logical choice is to get the better searching diamond, overlook approximately what lab is higher and save your money.
Don’t exclude comparing the coloration. The great way to do that is to ask to look loose un-set diamonds after which compare them facet by means of aspect. Take a white piece of paper and vicinity the diamonds the other way up and subsequent to one another at the paper. The white background provides evaluation to the diamond’s coloration and enables you distinguish the coloration differences between them. After making a decision in your personal approximately the quantity of shade a diamond has then check with the certification to peer what the grade is. Again, it doesn’t be counted who graded the diamond or what the grade is. In the give up you need to look it along with your very personal eyes and agree with your instincts approximately which diamond is proper for you.
Diamond certification is truly crucial to have and I do not assume you should purchase a satisfactory diamond without one. I do trust though, that a wholesome selection is one which involves you relating to the certification, evaluating diamonds facet by means of facet, and the use of your head. Let’s not forget about the cost of running with a good jeweler as nicely. A appropriate jeweler lends his/her know-how and offers an impartial opinion about every diamond’s traits. The very last selection approximately a diamond and whether it is right for you – need to be made by you. Not a grading lab!
