Round-Cut Cubic Zirconia Engagement Rings
Round-cut cubic zirconia engagement rings are one of the most popular stone shapes within the CZ market demanded by those who are about tie the knot. Iconic within popular culture, the modern round-cut has gone hand in hand with a bouquet of flowers ever since being designed almost one hundred years ago and seeks to maximise a stone’s total internal reflection. A milestone in gemology, the modern round-cut was the first cut to be mathematically modelled in order to maximize the reflection, fire and sparkle of diamond. Round-cut cubic zirconia engagement rings feature a CZ stone that imitates this cut. It is interesting to note however that a round-cut CZ stone will not necessarily be in the same proportion as that of a round-cut diamond and this is because of the differences in refractive index and dispersive power of the two stones.
Any deviation will only be to enhance the brilliance of the CZ stone unlike in diamond where deviation from the ideal is sometimes done in order to salvage the largest piece from the raw stone.
Round-cut cubic zirconia engagement rings are popular as solitaires, in three-stone configuration or with multiple side-stones. Given their affordability, 1 carat, 2 carat and even 3 carat cubic zirconia engagement rings are a real possibility.
Both yellow and white gold round-cut cubic zirconia engagement rings are available in a variety of shapes and sizes as well as those constructed from silver and platinum.
Round Cut Cubic Zirconia Engagement Rings by Carat
Set with round-cut CZ stones that are approximately 6.5mm in diameter in order to accurately simulate the size of a 1 carat diamond, 1 carat round cut cubic zirconia engagement rings are attractively sized yet still demure.
2 carat round-cut cubic zirconia engagement rings on the other hand are a bit more flashy as they are approximately 8.2mm in diameter. Note that even though the carat weight of the CZ has doubled in such case, its visible size when viewed from above has not and this is because the increased weight is spread across the depth of the stone as well which is not visible when the stone is set on a band.
Round Cut Cubic Zirconia Engagement Rings by Type
Set as a single stone on a simple band, a round-cut cubic zirconia solitaire engagement ring is a representation of probably the most timeless, classical, iconic and romantic symbol of love that has been presented through the ages.
Britney Spears, Natile Portman, Emily Blunt and Jennifer Aniston all sported round-cut engagement rings when their time came.
Other styles include three-stone round-cut cubic zirconia engagement rings in which there is not one but three stones of equal or different sizes and vintage round-cut cubic zirconia engagement rings which tend to have a broader band styled with elegant twists and turns that evoke an antique charm.
Conceived in 1919 by a Belgian diamond cutter by the name of Marcel Tolkowsky, his masterful study entitled “Diamond Design: A Study of the Reflection and Refraction of Light in Diamond” laid out precise ratios that must exist between the major components of the round-cut in order for it to maximise light return via the internal physical properties of refraction and dispersion.
The resultant shape is one that is made up of a flat top part known as the table that is cut onto a crown which is circular and expands to meet the top edge of a pavilion. The pavilion is conical in shape and tapers down at a steeper angle than the crown to a point at the bottom known as the culet. A thin ring known as the girdle separates the crown and pavilion.
All parts of the structure play a part in ensuring that the finished stone reflects as much light as possible.
Light enters the stone via the table, is allowed to bounce off the sides of the pavilion internally within the stone until it is finally reflected back through the table into the gazer’s eye like a brilliant white flashlight.
Combined with the fire that emanates from the crown, the brilliant, flashing effect of a cut stone is the adamantine sparkle that has kept generations of couples mesmerised throughout the ages.
