Every diamond is a miracle of time and place and chance. Like snowflakes, no two are exactly alike.

Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. Now there are globally accepted standards for describing diamonds: Color, Clarity, Cut, and Carat Weight. Today, the 4Cs of diamond quality are the universal method for assessing the quality of any diamond, anywhere in the world.

The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language and diamond customers could now know exactly what they were about to purchase.

No matter how beautiful a diamond may look you simply cannot see its true quality. The 4Cs of diamond quality will provide you with the information you need to know the diamond’s actual quality.

Cut

Diamond Cut does not refer to a diamond’s shape, but to the proportion and arrangement of its facets and the quality of workmanship. The amount of brilliance, sparkle and fire in a diamond is determined by cut. Grades range from ‘Excellent’ to ‘Poor.’

Color

Diamond Color, in most diamonds, actually refers to the absence of color. The less color in the stone, the more desirable and valuable it is. Some of these differences are not visible to the naked eye, but directly impact the overall quality and price of the stone.

Clarity

Diamond Clarity measures the amount, size and placement of internal inclusions and external blemishes. Grades run from flawless, with virtually no imperfections, to included, which contain a significant number of imperfections.

Carat Weight

Diamond Carat refers to a diamond’s weight. Generally speaking, the higher the carat weight, the more expensive the stone. Two diamonds of equal carat weight, however, can have very different quality and price when the other three C’s are considered.

10 Reasons Why You Should Never Buy a Diamond Online!

  1. You can’t sell a feeling on the Internet. Selling a diamond is not just about symmetry and the technicalities of the 4 C’s, it’s also about the feelings that this diamond will elicit when it is purchased and when it is given.
  2. While we are talking about the letters and numbers of the 4 C’s,  diamonds are so much more than that. A diamond is a work of nature. I could give you the dimensions of a woman along with a picture, but you need to see her to truly experience her beauty. The same goes for diamonds. You can’t truly experience the sparkle, shine and depth from a picture online.
  3. This brings me to where is the inclusion? How bright is the diamond? What is the quality? Is there a haze? What does it look like through a loupe? These are things you cannot know if you are buying diamonds online with an untrained eye.
  4. Would you buy a house without taking a tour first? You shouldn’t buy diamonds without seeing them first either. A store lets you see them, touch them and more importantly, examine them and COMPARE them to each other. No diamond dealer in the world buys diamonds sight unseen, why should you?
  5. Retail prices on the same diamond can range from a few thousand to almost $10,000, depending on where you are buying the diamond. If every diamond were the same, then everyone would buy from the store that sold it for the least amount of money. Obviously there are many differences in diamonds, such as brightness; scintillation, position and relief of inclusions and all of these things determine the beauty of the diamond. These are all things that need to be seen under a loupe.
  6. If it seems too good to be true, it usually is. I’ve said this before when it comes to buying a diamond while you are on vacation, but remember no one is giving anything away and there is usually a reason something is priced below market value. If you find something that you can’t pass up, buy it and then take it to your local jeweler to see if it measures up. Chances are when you actually go to buy the too good to be true diamond, it will be gone and you will then need to buy a not so good to be true diamond instead.
  7. A diamond is forever and Internet sites come and go. I’m not saying that brick and mortar stores or wholesalers don’t go either; some do, but not as often as Internet sites. In order to make the purchase memorable and special, part of that is sitting in front of a bunch of diamonds and choosing the one that speaks to you, not putting it in your cart and paying via PayPal.
  8. Because a diamond is forever, what are you going to do if your diamond gets a chip or your ring loses a stone? Most Internet sites will not provide maintenance, experience or service and if they do you will have to get your ring to them and hope it comes back as you sent it, with the exact same diamond. When you buy from a jeweler you get their expertise and time. You get their guarantee and appraisal. You get to take your ring in to keep it clean and maintained for as long as you own the piece and often you can upgrade your diamond for just the cost of the upgrade.
  9. There are so many ranges of colors and clarities when it comes to diamonds that is not just as simple as D – Z for color and FL to I3 for clarity. If it were, then all D FL diamonds would look alike and they don’t. You can’t possibly see the differences in these diamonds and compare them on the Internet.
  10. It is unfortunate but true that internet diamond dealers and sellers are not always looked upon as beacons of honesty. Between fake certifications and jacked up prices and the misgrading of diamonds it is important to find a jeweler that you trust so you can avoid these headaches and really enjoy the experience of buying a diamond.
