Engagement rings can be customized to fit the wishes of the couples. This is important since each couple has their own preferred style and design. Among the parts of an engagement ring that is customizable is the shape of its gemstone. It is important that couples are familiar with the characteristics of the different gemstone shapes available so that they will know which are aligned to their requirements.

Important Things to Know About Gemstone Shapes

Round

One of the most important factors that make round gemstones among the most sought-after gemstone shapes for an engagement ring is that they give out the most sparkle. The brilliance and fire of gemstones can be seen through its sparkle. Gemstones have two kinds of facets, the physical and virtual. The physical facet is the actual cuts found on the gemstone. When gemstones have more cuts on them, there are more directions that light will be able to bounce to. The bouncing of the light in multiple directions is called the virtual facet. 

As the virtual facet on gemstones increases, they are able to refract more light which adds to the brilliance and fire to the gemstone. Round-shaped gemstones are known to have around 58 physical facets that can give them more virtual facets. This has been done by design to maximize the brilliance and fire on the gemstones. In addition, this shape has smooth edges. This is important to avoid chipping on the gemstone.

The main drawback for getting a round gemstone on an engagement ring is that it is one of the most expensive shapes available. This is due to its popularity and the cutting process the gemstones go through to achieve the optimal number of physical facets.

Oval

This type of gemstone shape has a length-to-width ratio that ranges between 1.66 and 1.33. The oval-shaped gemstone is a modified version of the round-shaped gemstone. This design is meant to give the fingers an elongated look. There may be people that have fingers that are shorter and chubbier than normal. However, with oval-shaped gemstones on their engagement rings, these people can make their fingers appear leaner and longer.

This is one of the gemstone shapes that suffer from the infamous bow-tie effect. This is an effect that shows a dark area on the gemstone that looks like a bow-tie when you hold the engagement ring close to you. As you put the ring farther from you, the dark area becomes less pronounced. The dark area on the gemstone is caused by the leakage of light which happens on certain gemstone shapes.

Square (Princess cut)

This is the most popular fancy-shaped gemstone that is used in engagement rings. Square-shaped gemstones are also designed to maximize the brilliance and fire of the gemstones. These gemstones have around 57 physical assets, and they are excellent alternatives to round-shaped gemstones for engagement rings. The four corners of these gemstones make them appear larger than their round-shaped counterparts.

Among the drawbacks of this gemstone shape is that it is among the pricier choices for engagement rings due to its high brilliance and fire. In addition, the four corners put the gemstone at risk of chipping. However, to protect these corners, there is always the option of getting an engagement ring that has a bezel to provide safety to the gemstone.

Pear

What makes this shape unique is its teardrop-looking design. It has been designed to mix some of the characteristics of oval-shaped and round-shaped gemstones. The brilliance of the sparkle of this shape can effectively mask any imperfections and color. It also helps make the fingers look longer and leaner. However, this shape is significantly cheaper than a round-shaped gemstone.

There are two main drawbacks for this gemstone shape. It is one of the gemstone shapes that are affected by the bow-tie effect. Also, the tip of the gem puts it at risk of chipping, which is why there needs to be a prong on the engagement ring to help protect the tip from getting damaged.

Emerald

This is one of the oldest gemstone shapes used for engagement rings. Compared to other shapes, it has symmetrical cuts that are designed in straight lines. It has a unique way of showcasing its sparkle through its step cuts. It gives a “hall of mirrors” effect instead of the usual fire and brilliance exuded by other gemstone shapes. Due to its elongated shape, it can effectively make the finger of the wearer look leaner.

With its design, it is not meant to give out a brilliant sparkle which many people are accustomed to when it comes to engagement rings. It does not showcase any flashiness since its long parallel physical facets are meant to reflect long broad flashes of light. Couples who opt for this shape have to be careful that their gemstones are cut properly and exquisitely. This is highly advised because emerald-shaped gemstones that have not gone through the proper cutting process will show black areas on them.
