There’s a lot more to making a good buy on diamonds than one can read about for a couple weeks on the internet, and expect to go and make a good purchase with that info. Is it a good idea to learn? Absolutely, but don’t get fool hardy thinking you’re smarter than you are. One of the most common sales practices is to play along with the customer who thinks they know it all, and believe they’re doing everything right because they have an academic understanding of diamonds. Since most stores look for diamonds with undisclosed flaws (misgraded diamonds, which account for about 85% of diamonds on the market), one is even more easily mislead by a inaccurate certificate of a certain quality. You fall hook line and sinker without questioning it, BOOM, the dirty deed is done, and your diamond isn’t even close to being the quality you think it is!
NOW, how do you avoid this happening? Easy! Look at every diamond you consider buying under a microscope and (YOU) draw a picture of the inclusions relative to the size of the stone. Take that drawing from store to store and do it for every stone you are considering at each store. Also, ask to see GIA certified diamonds of a certain body color similar to what you desire, then compare them right next to the diamond they’re trying to sell you so you may judge more accurately if it is the white color you desire. Now for cut, just ask to see their finest cut diamond and compare the stones your considering side by side to see which one sparkles and reflects more light. Remember to make notes next to the drawing of the inclusions you made on each stores business card. It’s really easy to get cheated by just trusting a diamond certificate as there are soooo many intentionally bad graded ones out there! As you will notice in the chart in the photo the diamonds at the top show body color tints graded in alphabetical designations finest white to the left and heavily tinted yellow brown or grey to the right. Notice how little difference there actually is between grades, this is just one reason a person without extensive training can learn about how diamonds are graded but couldn’t even begin to accurately tell what color a diamond is just by looking at it, especially when different lighting environments tweaks a persons color judgements (just imagine trying to match paint by eye). In the pictures of 4 diamonds on the lower right hand side of the photo the top one is a technically white round cut, the next one down is a yellow tinted body color pear cut, the next a grey tinted princess cut and on the bottom a brown tinted princess cut. To better see the color differences between left to right enlarge the images and compare D to S-Z grades.
We buy diamonds from the public when they no longer need them, so I can tell you from experience when most people come in and say “I was told this was a really nice diamond…”, 90% of the time it’s amongst some of the lower quality grades, and about 25% of the time I’m not even interested because it is such a poor quality. The folks always say “well, I paid (some crazy amount)….” and we are flabbergasted! You don’t need the best there is, but you don’t need to get to get taken advantage of and end up with a junker either! Follow our simple steps to make an informed decision and don’t get suckered into a poor purchase by a good sales pitch.
