Everything You Need To Know About Diamond Cuts

By | Diamonds | No Comments

Cutting diamonds and other gems is a fine art. Not everyone knows how to do it, and even less know how to do it well. People often use the words “cut” and “shape” as synonyms; however the cut has to do with how well your gem interacts and reflects light, while the shape is quite literally the shape of the gem.

When it comes to cuts diamonds, because they’re so hard, require their own special methods for cutting. The Mohs hardness scale, created by the German mineralogist Friedrich Mohs in 1812, rates minerals according to how many (and which) other minerals can cut them. Since the diamond is the hardest mineral in existence, it can be cut only by its own dust.

When cutting stones, a gem’s index of refraction must also be taken into consideration. If this figure is high, and the gem is transparent, it usually must be cut to include many facets set at different angles to allow light to pass through the stone and be reflected from these facets.

In the case of diamond, there is a “brilliant” cut of 58 facets, which gives it that blindingly sparkly look. The diamond must be cut properly so most of the light that enters from the top facet is re-reflected upwards from the back facets, illuminating the entirety of the diamond even if it’s set in a ring.

A well-cut diamond adheres to the four C’s, which are:

  1. Cut: This is how the stone’s been cut. A well-cut stone is ranked higher than a shallow-cut stone by jewellers.
  2. Clarity: This is based on inclusions one would see in a diamond that’s been magnified ten times. Inclusions are often hidden once a stone has been mounted, and therefore won’t ruin the look of the gem.
  3. Carat: Each diamond is weight by metric carat (which is different than the term karat we see when talking about gold).
  4. Color: Every gem has a colour (or absence of colour) to them. The colour of the gem being used can determine which metal it would look better being set it.

The better these four C’s interact among themselves, the rarer and more expensive the diamond.

Everything You Need To Know About Diamond Shapes

By | Diamonds | No Comments

The shape of a stone can say a lot about a person, so it’s important to know what you want a ring to reflect before you buy it. Some common types of gem shapes include:

  • Round or traditional
  • Oval
  • Pear
  • Heart
  • Rose-cut
  • Marquise

When it comes to shopping for an engagement ring the shape of the gem is usually a good place to begin. Some popular diamond shapes for engagement rings include:

  • Round: This is considered a favourite by many and is the main shape chosen for solitaire (single stone) engagement rings. This shape is a classic, and makes for a timeless choice.
  • Princess: Square in shape, this also makes a great choice for solitaire engagement rings.
  • Cushion: The cushion cut looks like the cross between a round cut and a princess cut. Although the edges are rounded it has more of a squared off feeling than a round diamond.
  • Emerald: This shape is more rectangular than the others, and looks less fiery in the light. However the shape is timeless and incredibly popular.

Although each diamond shape is beautiful in its own way, it’s important that you know the style of the person you’re buying the ring for. Not every shape will work with every individual, so it’s important that you’re familiar with their personal style. What might seem like the right ring to you may not be the right ring for them.
