The Popularity of the Radiant Cut Diamond Ring Is No Accident!

Popularity of Radiant Cut Engagement Ring

Radiant cut diamonds are becoming increasingly popular for engagement rings due to the quality of the cut. Radiant cut diamonds are created by combining seven different methods of diamond cutting into one style and produce a rectangular or square shape with beveled corners and brilliance-like facets cut in the lower half (pavilion). The cut presents unparalleled brilliance and provides a unique sparkle known as "Crushed Ice."

Couples who are currently engaged in the UK benefit from the many qualities of the radiant diamond engagement ring:

Maximum Durability & Security:

The trimmed corners of the Radiant cut eliminate the sharp-pronged corners associated with the Princess and Emerald cuts, thus decreasing the likelihood of them chipping. As a result, a radiant cut diamond engagement ring is safer and is a good option for people who wear their ring continuously.

Maximum Size Illusion:

A Radiant cut diamond ring has a wide table as well as the generous diagonal measurement to its facets; therefore, radiant cut diamonds usually look larger than diamonds of other cuts with the same carat weight. This can be a significant consideration for budget-conscious people in the UK, as it provides the most visual impact at the lowest possible price.

Understanding the Cut, Clarity, Colour, and Carat of Radiant Cut Diamonds

The 4Cs of Radiant Cut Diamonds
Selecting the perfect radiant diamond requires balancing the 4Cs specifically for this cut.

Although the cut, clarity, color, and carat of a diamond are the 4Cs that most people associate with all diamonds, each unique diamond cut (including the radiant cut) has its own set of preferences for how to best show off the diamond's beauty and value.

1. Cut (The Most Crucial Factor)

The cut of the diamond refers to the way the diamond was cut and shaped (and not the actual shape of the diamond). When looking for a radiant cut engagement ring, the biggest factor in determining the quality of the cut is the length-to-width ratio, or L/W ratio.

Square Radians:

An L/W ratio of 1.00-1.05 will be the most square.

Rectangular Radiants:

An L/W ratio of 1.20-1.50 is recommended for that elegant and elongated look that many people desire from their radiant diamond engagement ring.

2. Importance of Colour

The ability of a radiant cut diamond to manipulate light has the potential to produce a greater amount of body color than an equivalent round-brilliant-style diamond.

Recommendation:

It is recommended that an H or better stone (H to D color scale) should be selected for engagement ring settings in either platinum or white gold to produce a color "icy white" visual effect on the diamond when viewed against the metal. For yellow and rose gold settings, a color of J or K will look excellent due to the fact that warm metals help to hide the color tints found in the diamond.

3. Clarity (Where to Save)

For purchasers of a radiant cut diamond ring, this is very good news! A radiant cut's complex faceting pattern can mask many minor inclusions (flaws).

Recommendation:

We tell our customers that VS2 or SI1 clarity grades provide an excellent balance of quality and value. You are purchasing a diamond that will be eye-clean without having to pay extra for perfect clarity (Flawless). Every radiant cut diamond engagement rings from Layla Diamonds comes with a guarantee that it will be eye-clean.

4. Carat Weight (Price-Determining Factor)

While the weight of a diamond is determined by carat weight, and that therefore determines the price of a diamond, we have found that radiant cut diamonds tend to look larger than their actual carat weight indicates and provide a good value. When preparing a budget for buying a radiant cut diamond ring, make sure to put the highest priority on cut and color over carat weight.

Select an Engaging Setting for Your Radiant Cut Engagement Ring

Radiant Cut Ring Settings
Choosing the right setting is essential to enhance the stone's natural beauty.

When selecting a setting for your engagement ring, it must be compatible with the stone; therefore, choosing a setting for your radiant cut diamond ring is an essential step in creating the perfect look for your ring.

Below are the most commonly used settings within the UK:

1. Classic Solitaire Setting

Reason for selection: Classic Solitaire settings tend to highlight the incredible beauty of radiant cut diamond engagement rings because they have a very thin band that allows light to pass through the diamond, producing incredible brilliance. Classic solitaire settings are also typically manufactured from either platinum or white gold; therefore, they also pair extremely well with radiant cut diamonds.

Layla Diamonds Suggestions: Use a setting with V-shaped or secure basket prongs to protect the corners of the diamond.

2. The Sparkling Halo Setting

Why it works: A halo setting encircles the center stone with a border of smaller, brilliant diamonds. This immediately increases the perceived size of the primary radiant cut engagement rings and boosts overall sparkle. This is currently extremely popular with those wanting full-on glamour and sparkle.

  • Layla Diamonds Tip: A hidden halo (instead of visible on top), where the diamonds sit just below the girdle, is a subtle but luxe touch.

3. The Three-Stone Setting

Why it works: The surroundings of the center radiant with two smaller stones, perhaps trilliant or trapezoid cuts, add symbolism and an extra dimension. It makes for a very rich, balanced, radiant diamond engagement ring.
