As engagement ring spending among both millennials and older couples who are remarrying is on the rise, it is imperative to become an informed purchaser. Learn about the 4 Cs of diamonds: cut, clarity, color, and carat to ensure a successful diamond purchase experience.

Carat Weight

Carat weight refers to the physical size or weight of a diamond. One metric carat (also referred to as “ct”) equals 0.200 grams or 1/5th of one gram–roughly equaling the importance of a paperclip. The term “carat” derives from ancient practices of weighing precious metals and gemstones against seeds from carob trees that had uniform sizes and weights; later, in 1907, the Fourth General Conference on Weights and Measures became the standard measurement for diamond measurement worldwide.

Carat weight is an integral factor in assessing a diamond’s value but does not directly translate to its size. Diamonds of equal carat weight may appear different due to differences in shape and cut grade – for instance, a round brilliant diamond will appear more prominent due to having more surface area.

The price per carat of diamonds may depend on several factors, including the rarity of its rough crystal source as well as clarity and color qualities. A more desirable diamond will command higher prices per carat than one with similar cut and clarity grades.

Be mindful that higher carat weight doesn’t automatically translate to more extensive or more costly diamonds. Social media often fuels this misconception that bigger is always better and can lead to overpaying for diamonds.

Finding a beautiful balance between carat weight and cut grade when selecting a ring can be challenging, but finding such an arrangement can make all the difference in its beauty. Lower-carat weight diamonds with excellent cut grades still sparkle as brightly as their more costly cousins; in fact, some of the most stunning diamonds feature this combination, creating something called the magic sizes’ in the diamond industry lingo. That is why working with an established jeweler when purchasing diamonds is crucial!


Diamonds are natural stones, meaning they contain flaws known as inclusions and blemishes that impact their clarity grade and value. Clarity refers to how free from these imperfections a diamond is; more inclusions or blemishes mean lower clarity grades and weight; inclusions form naturally during intense temperatures and pressures used to develop it, creating internal or external imperfections. However, rare and expensive diamonds with high clarity grades exist.

The clarity of a diamond has an impactful effect on how light passes through and reflects from its surface and how brightly it sparkles. The higher its clarity grade is, the fewer inclusions it contains, and the brighter its shine will be: FL (flawless), IF (internally flawless), VVS1, and VVS2 (very, very slightly included), as well as SI1, S2, and S3 (slightly included), are amongst its highest grades.

When selecting an engagement ring diamond, many people prioritize one with a higher transparency grade. This is particularly important for emerald- and Asscher-shaped diamonds, which contain facets that emphasize transparency and may make inclusions more obvious; round, princess, oval, marquise pear, and heart-shaped diamonds feature brilliant facet patterns designed to reflect light from multiple directions and conceal inclusions more effectively.

One factor affecting diamond clarity is its inclusion type and position. Crystals, feathers, surface scratches, or inclusions that interfere with light transmission can decrease its clarity grade and diminish brilliance and beauty.

Fluorescence also plays a part in determining a diamond’s clarity grade; diamonds with solid fluorescence exhibit a blue or yellow-tinged glow in certain lighting conditions, whereas those with no or weak fluorescence appear white.

Once you’ve selected a diamond shape and carat weight, the next step should be selecting a setting or mounting. This determines how your ring will appear visually as well as its style – solitaire, pave, and bezel settings are just a few options available; each offers different levels of comfort when worn; others may make cleaning or managing easier; bezel settings may even keep the diamond from getting caught on clothing or equipment if active people wear their rings!


When choosing an engagement ring diamond, it should capture her imagination and command attention. To do so successfully, it must feature an attractive shape that suits her personal preferences while emphasizing its beauty.

Happily, couples now have more options than ever when selecting a diamond to symbolize their love. From classic round and princess cuts to more modern marquise and pear shapes, there’s sure to be one to suit any personality!

A diamond’s sparkle comes from how it interacts with light, and several factors, including brightness, fire, and scintillation, determine this interaction. Intelligence refers to how reflective its surface is; fitness measures light reflections, while fire refers to how many color flashes there are; scintillation measures the contrast between dark and light areas within a diamond.

All these elements combine to form the hallmark look of a diamond, making its cut one of the most crucial factors in creating its distinct aesthetic. A good amount determines how well a gem sparkles and reflects light, as well as resolving its overall appearance on a facet of its surface.

Diamond cutting began in the 14th century with point cuts – octagonal crystal faces polished for even and unblemished surfaces. From these points, amounts evolved modern round brilliant diamonds; modern diamond cutters now understand how different proportion combinations affect light performance in order to maximize brilliance and fire.

Other diamond shapes include the art deco-inspired emerald cut and antique cushion-cut diamonds, which provide special scintillation. Their square or rectangular cut features rounded corners referred to as “pillow cuts.”

Emerald- and Asscher-shaped diamonds require higher clarity grades than others due to their rectangular facets, which emphasize transparency and may show more inclusions than round or princess-cut diamonds. To prevent their flaws from being apparent, VS1 clarity grades or higher should be selected, while round and princess cut diamonds have brilliant facet patterns that naturally hide many inclusions.


When selecting a ring, the chosen metal must withstand wear and tear over time. Most alternative metals tend to be stronger than precious ones and can withstand more wear and tear, making them suitable for daily wear and tear compared to their more costly counterparts. Many are also more cost-effective alternatives compared to precious ones, making them an affordable choice.

Metal type can have an immense effect on how a ring looks and feels in your hand, with gold being one of the most sought-after choices available with various finishes and thickness options.

Platinum rings are also highly sought-after as an alternative to gold, with their premium price bringing with them additional advantages like hypoallergenic and non-corrosion properties. Furthermore, this metal’s superior strength makes it suitable for holding large diamonds securely.

Titanium and tungsten carbide can serve as great alternatives to precious metals, with titanium being lightweight with silvery hues but can also come in black shades. It ranks very highly on the Mohs scale of hardness and ranks especially highly for use as men’s rings, often featuring tension settings paired with diamonds. Tungsten carbide, an extremely durable metal that comes in black but may also come in white shades, can be made into multiple styles and colors but must be sized correctly the first time around as it cannot be resized later on!

Tungsten makes an excellent material for wedding bands, offering aesthetics similar to gold but being more resilient and hypoallergenic. Tungsten comes in various widths that can be cut into square or oval shapes; additionally, its surface can be polished up to a mirror finish to provide maximum shine and reflectivity.

Other metals gaining in popularity for ring designs include opal and tantalum. Opal is an uncommon mineral with translucent qualities and a blueish tint, often combined with diamonds to form contemporary designs. Tantalum, on the other hand, is an earth metal that comes in a blue hue and has unparalleled scratch resistance; additionally, it can even be engraved.
