1. Design Styles

2. Setting Styles

3. The Anatomy of the Diamond

Let's get to know the anatomy of the diamond before we move on to different shapes of diamonds:

Table: A diamond’s largest facet.

Crown: The part of the diamond that extends from the girdle to the table.

Girdle: The rim that separates the crown from the pavilion. The girdle is where a diamond is held while setting it in jewelry.

Diameter: The measurement from the girdle, the widest horizontal line surrounding the diamond.

Pavilion: The part of the diamond that extends from the girdle to the culet.

Cullet: The tip of a gemstone. An untrained eye should not be able to see the culet.

Depth: The measurement from the culet to the table, the highest vertical line on the diamond.

4. Shapes

A diamond's geometric outline and physical form are referred to as shapes. Shape influences the stone's overall appearance. Each diamond shape comes with its specific requirements and technical characteristics.

Round cut diamond

Round

Due to its shape, the round diamond has the ideal light return and brilliance. Hence, it is the most common shape choice when buying a diamond. Diamond manufacturers have utilized theoretical and technological advancements to create the cuts we see today. Very good and excellent cut round diamonds are exceptionally radiant. They are more favorable in terms of balancing cut, color and clarity grades, while still providing the sparkle you desire.
Princess cut diamond

Princess

Princess-shaped diamonds are the most popular non-round diamond shape. Traditionally a princess-shaped diamond has pointed corners like a square, but it can also be rectangular. Compared to round-cut, princess-shaped diamonds tend to show color in the corners. Choosing this shape may require a better color grade which increases the cost. However, due to geometrical advantages, the princess shape causes minimal waste and slightly lowers the price to carat when compared to other figures.
Emerald cut diamond

Emerald

You may want to prefer a better clarity grade if you are choosing an Emerald shape diamond. This shape emphasizes a diamond's clarity due to its geometrical form and provides a more accessible view of the inclusions and the blemishes. The cuts of the bottom part and the big, open upper part of the diamond give the emerald diamond its distinct appearance. Emerald diamond owes its aesthetic look to dark and light planes, manifesting a hall-of-mirrors look rather than the apparent brilliance of a round diamond.
Cushion cut diamond

Asscher

This strikingly gracious shape is essentially identical to an emerald-cut diamond, except that it is square. If you choose to go with a lower clarity grade, beware that inclusions and blemishes are easier to distinguish, just like with the emerald-cut. This shape also tends to reveal color in the corners, similar to the princess shape; hence you might want to invest a bit more in a higher color grade. The modern Asscher cut diamond has larger step facets, a taller crown and a smaller table than a square emerald cut. When compared to the emerald-cut, this combination frequently creates more brilliance.
Marquise cut diamond

Marquise

Marquise diamond has a unique shape that features broader facets than any other shape and therefore looks more significant compared to other shapes with the same carat weight. The length of the marquise diamond is flattering to fingers, making them appear thinner. You may find that the marquise diamond resembles an eye, however, you can customize how narrow or wide the shape is.
Oval cut diamond

Oval

Oval diamonds have the extra benefit of giving the impression of a larger carat diamond, thanks to their elongated shape. The narrow shape may execute the desired effect of making your finger appear longer and slimmer. The oval is an excellent alternative for someone who likes the look of a round diamond but wants something a bit more unique, because the two forms have similar fire and brilliance.
Pear cut diamond

Pear

With its single point and rounded edge, this shape of diamond is also known as a teardrop. The pear shape's distinct appearance makes it a popular choice for various diamond jewelry. The thin end of the pear-shaped diamond always points toward the fingers when it's on the hand and gives the subtle slimming effect on the fingers. The pear-shaped diamond, like the marquise and oval cuts, is available in a range of narrow or broader cuts.
Heart cut diamond

Heart

The ultimate symbol of love, a heart-shaped diamond's unusual appearance makes it a standout choice from various alternatives. Because the tip of this design tends to reveal slight color, you may want to budget for a better color grade than you would for a round diamond. Heart-shaped diamonds are available in a range of narrow or wider silhouettes; however you prefer.
Cushion cut diamond

Cushion

Cushion diamonds come in various forms, from square to rectangular, whichever you prefer. This one-of-a-kind form has been a popular shape that has rounded edges and appreciable facets to boost brightness. Because these larger facets might show inclusions easier than other shapes, it may require a higher clarity grade than you originally planned.
Radiant cut diamond

Radiant

Radiant diamonds create an excellent bridge between cushion and princess with their square-like shape with trimmed corners. This unique type of corner is the hallmark of this shape, and they add to its popularity. It is highly desirable among the diamond community when set with baguette or round diamonds.

5. The Four C’s of Diamond Grading

So you may have heard the term the four C’s of diamonds, these refer to the cut, color, clarity and carat of the diamond and have an important role to play in budget considerations.

Cut

The cut of a diamond refers to the symmetry, arrangement of facets and the proportions of a diamond, which all factor in the way a diamond transmits light. Graded on a scale between poor to excellent, the cut of a diamond is what determines its brightness, fire and sparkle. Meaning that a poorly cut diamond will have less sparkle. The better the cut is, the more sparkly the diamond will be.

Color

A perfect diamond is colorless like a drop of pure water. When we talk about the color of a diamond, we refer not to the presence of color in a diamond, but to the lack of it. The scale of diamond color ranges from D to Z, with D signifying a perfectly colorless stone. D rated stones are extremely rare and are thus the most expensive. As you move down the scale, diamonds become more colored and less expensive.

Color
Clarity

Clarity

Diamond clarity refers to the absence of inclusions (internal imperfections)  and blemishes (external imperfections) on a diamond. The Gemological Institute of America (GIA) rates clarity on a scale from Flawless to Included. Professionals carry out this assessment under 10x magnification. A diamond that has some inclusions or blemishes that are not visible to the naked eye is called ‘eye clean’. So when looking for a high quality diamond, make sure that your diamond is eye clean.

Carat

In simplest terms, carat is the measurement unit for how much a diamond weighs. One carat equals 200 milligrams. To ensure precise measurement, each carat is subdivided into 100 points. One thing to keep in mind is that carats do not equal size, which is a common misconception. As it is harder to find larger carat stones in nature, the higher the carat weight, the more expensive a stone will become. And the pricing will not be linear, meaning that a one carat diamond will be more expensive than two 0.5 carat diamonds together. One more thing to know about carats is the ‘total carat weight,’ which is used when more than one diamond is used in a piece of jewelry. Total carat weight refers to the combined weight of all the diamonds used in the piece, or, for earrings, the pair.

6. Metals

At Eternate, we combine our 60 years’ experience with modern die-making techniques to create a non-porous, tensile metal property with excellent surface quality. To achieve their stunning color and shine, we purify and mix all metals and alloys used in our processes. Whichever metal you choose, rest assured that our exclusive in-house knowledge results in exquisite and durable jewelry with not only great designs but also the longest life.

We are committed to sustainability. Therefore we use 100% recycled gold in all Eternate products. Gold is a soft metal, which needs other metals to be added to it for strength and different complexions of colors. The word ‘karats’ refers to the amount of gold content in the jewelry. Do not confuse it with ‘carats’, which is the measurement unit for diamond weight. At Eternate, we offer three options of gold karats: 18K, 14K, and 10k, each containing 75%, 58.5% and 41.7% of gold, respectively.

7. Alternative Engagement Rings

Traditionally, when we think of an engagement ring, we think of a diamond solitaire. However, there are actually no rules for how an engagement ring should look like. In our opinion, any ring that symbolizes your intention to build a life together and that really speaks to your unique story should be your engagement ring. That is why at Eternate, we also offer a wide range of exquisite alternative engagement rings. Alternative engagement rings are rings that break away from tradition, in their use of different and colored gemstones, non-conventional settings and unique designs. They offer a great option to set your engagement apart and celebrate your one of a kind story. Our alternative engagement rings boast moss agate, alexandrite, opal, moonstone, black rutilated quartz and blue sandstone options. However, should you want some other gemstone, let us know and we will be happy to source it for you.
