How To Spot A Good Diamond For Your Bride?

 April 19, 2016

No two diamonds are exactly alike! This is one of nature’s miracles and God’s master craftsmanship.

We hear about diamond’s shapes being round, emerald, princess or pear but its’ cut is a more important consideration because a cut determines how the diamond interacts with light. Their brilliance is dependent on how the rock is cut.

1) The Cut

The Gemological Institute of America (GIA) is the premier group which classifies the value of a good diamond. According to its website, ‘a diamond’s cut is crucial to the stone’s final beauty and value. And of all the diamond 4Cs, it is the most complex and technically difficult to analyze.’

There are five scales to a diamond’s cut: Excellent, Very Good, Good, Fair and Poor.Click To Tweet

An excellent cut has an even pattern of bright and dark areas, its symmetry is more precise and the brightness, fire (scattering of white light) and scintillation (sparkle) are evenly done. As these factors diminish, the scales also go from excellent to poor. ‘A well-cut diamond will direct more light through the crown.’

GIA’s diamond cut grade also takes into account the ‘design and craftsmanship of the diamond, including its weight relative to its diameter, its girdle thickness (which affects its durability), the symmetry of its facet arrangement, and the quality of polish on those facets.’

2) The Clarity

Another factor to look at is Clarity. There are two considerations to a diamond’s clarity. The internal characteristic is called an inclusion (intrinsic impurities in the atomic level) and its external characteristic is called blemishes (occurs when the diamond is cut and polished). No diamond is perfectly pure but the closest to purity one is, the more valuable it is.

GIA scales the clarity in six categories: flawless, internally flawless, very, very slightly included, very slightly included, slightly included, and included.

A ‘flawless’ diamond has no inclusions and no blemishes visible under magnification. An ‘internally flawless’ diamond has no inclusions visible under 10x magnification. ‘Very, very slightly included’ ones have inclusions that are so slight and difficult to see even by a skilled grader. ‘Very slightly included’ is more common in wedding and engagement rings. ‘Slightly included’ has inclusions that are noticeable and included has obvious inclusions, which may affect transparency and brilliance.

10x magnification is required to see any inclusion or blemish. Find a good jeweler who can provide you with tools to see where inclusions lie.

3) The Color

In terms of color, a diamond may be classified according to its lack of color. GIA says, ‘a chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. GIA’s D-to-Z color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to master stones of established color value.’

This means that if your diamond has tints of color in it, the farther it is from the high color grade. They can go from colorless (D-F), to near colorless (G-J), to faint (K-M), to very light (N-R) and light (S-Z). Again, to the untrained eye, this color grade may look the same so you need to have a trusted jeweler who can issue you a diamond that is certified by the GIA.

What about colored stones? These are not included in the colorlessness scale and stones that have strong tints of brown or yellow are outside the scale. ‘Colored diamonds’ are often laboratory-produced. However, the infamous blue diamond gets its hue from the formation of the diamond absorbing yellow light thus reflecting a blue tint. It is rare and costs millions of dollars.

You will be able to find good diamonds when you look at the right places and more often than not, you will come across the right people who can give you value for your money’s worth.

  1. Admittedly, I learned new things here on diamonds. I knew there were differences, even types of diamonds. Now I know how they could also be classified. Once again, proof that reading really is good. The next time I talk to someone about jewelry, I have a thing or two to say about diamonds!

  2. I once met a jeweller and he would talk intensively about diamonds. He taught us about cuts, clarity and colors. He even showed a small piece of tong-like device that could determine if the stones we are wearing are real diamonds. I had fun during that meeting. And I never thought diamonds can be real interesting. And as you talk about diamonds today, I all the more appreciate and wish that my husband would give me a pair of diamond earrings 🙂

  3. I remember when my hubby bought me a “sorry ring”(Imagine there is kind of right I am not aware of, it looks like an engagement ring). So am not that a jewelry addict and I do love that no value ones (iwas nakaw purposes) so I don’t know whats the difference between them so I told him that was a fake one and still don’t wanna talked with him.So he left that ring in our bed. But as i’ve read this post I find it helpful esp. to me(us who doesn’t even know about diamonds). So maybe next time when we talked about jewelries I have something to share with him.

  4. Never been interested in what is good diamond, but that was really informative and I’m sure I did had to know this for future shopping or helping out someone. Thanks for the informative post 🙂

  5. This is really interesting. I haven’t really thought about diamonds since engagement ring shopping! I have always wondered about colored diamonds and how they were made. It makes a lot more sense that they are often laboratory-produced. I think a good diamond is hard to beat so I always opt for clear diamonds. I am glad to see my instincts are mostly right! Though I wouldn’t turn down a colored diamond either! 🙂

  6. I knew that when looking for diamonds you should check the 4 Cs, carat, cut, color, and clarity, but I must say some of the things that you mentioned here like the fact that the colored ones are produced from the lab. That’s an interesting info to learn.

  7. I definitely learned something new here. I had no idea there was more to know about diamonds. I only know that they’re the hardest rocks out there. Good to know some additional facts. I could definitely use this knowledge when the time comes when I need to look for a diamond for my special someone. Thanks for sharing. Really informative post.

  8. Oh , look what a great website I have found ! Diamonds are a girl’s best friend …. Marilyn already knew ! I have got a few Jewish friends in Antwerp /Belgium , the center of the European diamond market . I love getting some new bling bling from there ,because first of all you know what you get , but even more the fact , that you can choose the ring/collar/earrings naked (without the stones) and then go for the stone of your very own choice to be fitted . I could spend hours in that lady’s paradise shopping center . What really amazes me , is the fact , that a human body can be turned into a diamond . There is a company in Switzerland , that makes diamonds out of the ashes of your beloved ones , which to me is such a lovely idea . Who wouldn’t want to become a diamond , that lasts forever ?

  9. This one’s an educational post. i just knew that the cut of a diamond is important because it will resemble the brilliance of it. just wow! i only see diamonds when i pass by jewelry stores and i admire it from outside. well, it’s inviting. and of course, diamonds are a girls bestfriend. 🙂

  10. After reading your blog post, I felt my IQ level about diamonds have level up, maybe switching careers to a diamond classifier will be rewarding? Haha!

    Kidding aside, thanks for sharing as this info, I learned something new 🙂
