Understanding the Basics of Diamonds

When it comes to diamonds, there is a world of fascinating information to explore. Let's dive deeper into the four most important factors to consider when evaluating a diamond: cut, clarity, carat, and color.

The Four C's: Cut, Clarity, Carat, and Color

Diamond Cut

The cut of a diamond refers to how well it has been shaped and proportioned. This factor plays a crucial role in determining the diamond's overall look, brilliance and sparkle. A well-cut diamond will reflect light in a way that enhances its beauty and even makes it look bigger, while a poorly cut diamond may appear dull and lifeless. In my personal opinion this is the most important factor that sets a stunning diamond apart from a not so great looking diamond.

Diamond Clarity

Clarity is another essential aspect to consider. It refers to the presence of any internal or external flaws, known as inclusions and blemishes, respectively. The fewer imperfections a diamond has, the higher its clarity grade will be. Diamonds with higher clarity grades are rarer and more valuable but also get expensive quickly. Your aim when purchasing a diamond should be to find a stone that is eye-clean, meaning it doesn't have any imperfections visible to the naked eye, and many VS2 diamonds pass as eye-clean. Even many SI1 diamonds may still be eye-clean depending on where the inclusion is located within the diamond. Inclusions are also easier to spot in a step cut emerald diamond than in a more faceted diamond like a round brilliant cut where inclusion get lost within all the sparkle and reflections. The bigger a diamond, the easier it is to see any inclusions. 

  • FL -  Flawless: No internal or external clarity characteristics
  • IF- Internally Flawless: No internal clarity characteristics
  • VS1, VS2 - Very Slightly Included: Inclusions not typically visible to the unaided eye
  • SI1, SI2 -Slightly Included: Visible under 10X magnification and may be visible to the unaided eye
  • I1, I2, I3 - Included: Inclusions visible to the unaided eye

Diamond Carat

Carat is a measurement of a diamond's weight. One carat is equivalent to 200 milligrams, and larger carat weights are generally more valuable. You may also hear the weight of a diamond referred to in points. One carat is equivalent to 100 points, so a 75-point diamond is equal to 0.75 carats. Keep in mind that carat weight solely indicates the mass of a diamond, while size pertains to its physical dimensions. A deeper cut diamond has a lot of it's weight hidden in the lower belly and will look smaller from the top than a diamond with better proportions. As a result, two diamonds with identical carat weights may exhibit varying sizes due to differences in their dimensions.Conversely, diamonds may share the same diameter or depth, yet their carat weights can differ. However, it's important to note that carat weight alone does not determine a diamond's worth. The other three C's also play significant roles in determining its overall value. 

Diamond Color

Color grading is an essential factor in diamond evaluation. The Gemological Institute of America (GIA) grades diamonds on a scale from D (colorless) to Z (light yellow or brown). Colorless diamonds are the most sought after due to their rarity. The presence of color can affect a diamond's cost, so it's crucial to consider this aspect when making a purchase.

Keep in mind that the metal color of the ring setting also impacts how the diamonds color is perceived. In a yellow gold of rose gold setting, a diamond will always appear warmer than in a white gold or platinum setting due to the reflections of the metal in the diamond.

The Appeal of Rose Cut Diamonds

If you prefer a more Art-Deco look a rose cut diamond can also fit the bill and be a different look to the more traditional diamond cutting. Rose cut diamonds can come in many shapes, although the round rose cut is the most common. Their triangular facets at the top and low profile design makes them an interesting choice if you prefer a little different look.

Natural vs. Lab-Grown Diamonds

In recent years, lab-grown diamonds have gained popularity for their ethical and sustainable properties. These diamonds are created in a controlled environment using advanced technology that replicates the natural diamond-growing process. They have the same physical and chemical characteristics as natural diamonds but are typically more affordable.

While natural diamonds are formed deep within the Earth over millions of years, lab-grown diamonds are created in a matter of weeks. This difference in origin has sparked a debate among consumers. Some prefer the allure and mystique of natural diamonds, while others appreciate the eco-friendly and conflict-free nature of lab-grown diamonds.

When deciding between natural and lab-grown diamonds, it's essential to consider the advantages and disadvantages of each type. Natural diamonds have a timeless appeal and are often considered a symbol of luxury. On the other hand, lab-grown diamonds offer a more affordable and sustainable option without compromising on beauty and quality.

Ultimately, the choice between natural and lab-grown diamonds depends on your personal values and preferences. Both options have their merits, and it's important to make an informed decision that aligns with your beliefs.There is no visual difference in appearance between a lab grown or a mined diamond.
