Remember the Four Cs of Diamonds

You already know your ABCs, but what about those four Cs of diamonds. Antique diamonds are filled with character and very distinct. You can use the same basis for grading them as you would with a modern diamond. The four Cs are cut, color, clarity, and carat. When purchasing an antique diamond, you need to be aware of the different traits in these categories.

The Diamond Cut

The cut refers to how light interacts regarding the diamond's proportions, polish, and symmetry. The shape of the diamond is the outline of the stone. It comes in various styles, such as emerald, heart, and marquise. When a diamond needs to be cut, it is an intricate process requiring the cutter's skill and patience. That fact is evident with antique diamonds. Unlike using laser cutters for modern diamonds, these shapes were hand-cut by a master artisan. The diamond's shape says a lot about the wearer's style. Every shape has a tradition and character, ranging from elegant to dramatic. Many antique diamonds will have the following cuts:

Rose Cut

This cut is the oldest shape of diamonds. They have been used since the 1600s. Since the technology was limited, many jewelers could only cut the rings into a rose cut. However, they still were able to create some stunning pieces. The cutter works with the natural shape of the diamond to bring out its charm and beauty. The rose cut often has a flat bottom and floral-like facets on the top. With this cut, the diamond provides an alluring yet demure appearance

Old Mine Cut

Another diamond cut is the old mine cut. It is known for its deep pavilions, small tables, and high crowns. As technology progressed, jewelers could make more intricate shapes than a rose cut. The 58 facets are paired with a deep pavilion instead of a flat base. This cut gives a greater play of light with more brilliant sparkle. Over time, this cut became very popular. 

Old European Cut

The old European cut is one of the newer cuts that have improved pavilion proportions, a larger table, and a perfect circular outline. This technique places the diamond on a wheel where the jewelers could "open up" the stone to a higher degree, giving it more light to showcase its beauty and unique patterns.

Clarity Scale

Since diamonds are a natural substance found in the Earth, they can develop blemishes and inclusions. These characteristics are known as the clarity of the diamond. With the help of magnification, the inclusions are assessed according to their size, position, relative visibility, and number. The diamond's clarity is graded on a scale:

  • F- Flawless
  • IF- Internally Flawless
  • VVS1-2— Very, Very Slightly Included
  • VS1-2— Very Slightly Included
  • SI1-2— Slightly Included
  • I1-2— Included

It is very rare to have an F or IF diamond. Those clarities are very expensive. As you go down the scale, the rarity and price will decrease. Many purchasers buy an "eye clean" diamond, meaning the stone has no inclusions or blemishes visible to the naked eye. Remember that if the diamond is in the SI range, those inclusions can only be seen with the power of 10x magnification. 

Antique Diamond Color Guide

You might think that diamonds have only one color, but there are degrees of color. Antique diamonds are assigned a letter grade based on their color, starting from D and ending at Z. These scales are as follows:

  • D through F – "colorless"
  • G through J – "near colorless"
  • K through M – "faint"
  • N through R – "very light"
  • S through Z – "light"

Like F or IF diamonds, D to F range diamonds are rare and expensive. Nearly colorless diamonds do look white to the untrained eye. With antique and vintage diamonds, you are more likely to find ones with a touch of color. These diamonds have more characters and are more beautiful than those bright white stones. Remember that the cutting techniques of the rocks often hide the actual color of the diamond. You want to look at the whole package of the diamond instead of focusing on one type of grade. While two stones can be graded the same, they may look completely different in real life. Choosing an antique diamond is a personal decision. Find one you love and not one you "should like" based on a scale.

Diamond Carats

Finally, all diamonds are measured in carats. That is the weight equal to 0.20 grams. Every carat is subdivided into 100 points to accommodate those fractional sizes. As you may have guessed, bigger diamonds are more rare and expensive than those smaller ones. Diamonds can look smaller or bigger than the actual weight. In some cases, you might see the term "faces up larger," which means the diamond has the appearance of a bigger stone.
