Cushion Cut Diamonds

A cushion cut diamond is the perfect answer for those torn between round brilliant and princess or square cut diamonds. Cushion cut diamonds were once the standard cut for diamonds, before round brilliant cuts took over. With their soft, rounded corners, cushion cut diamonds bridge the gap between round brilliant cuts and princess cuts. At Schwanke-Kasten Jewelers, we have a beautiful array of GIA certified cushion cut diamonds for your engagement ring or jewelry piece.

PROS & CONS of Cushion Cut Diamonds

Jewelers and recipients alike, enjoy this design for its classic and timeless aesthetic. Furthermore, gemologists have determined these cuts to have the most dispersion of light, or fire. Additionally, the jewelry market typically prices round brilliant cut diamonds higher than cushion cut for two reasons.

Demand
Less waste

However due to the deeper cut needed for this design, you will need to overcompensate with a larger stone than anticipated.

4 C’S

CUT:

Chunky vs Crushed Ice: Jewelers refer to these two terms when talking about the back facets and light reflections. If the light reflections appear in broad flashes, it refers to “chunky” aesthetic, if it appears as broken glass

"Crushed Ice" Cushion Cut — “Crushed Ice”

Length-to-Width Ration: Cushion cuts can come in “square” ratios as well as varying rectangle ratios. We should mention that you ought to avoid a length to width ration between 1.06 to 1.10.
Standard vs Modified Brilliant Cushion Cuts: Beginning in the 1920’s, diamond cutters added an extra row of facets beneath the girdle. However there is minimal affect on the beauty or structural integrity of the diamond.
Depth and Table: look for a cushion cuts with a depth and table under 70%. As well as symmetry and polish that is very good or excellent.

CARAT WEIGHT:

As we previously mentioned, cushion cuts tend to appear smaller than their round counterparts due to the depth of the cuts. That being said, if size is an issue, you may have to go larger than anticipated.

COLOR:

Cushion cuts show more color than round brilliant but this effect is negated by their brilliance and dispersion. However, we suggest looking for cushion cuts with color grades of I or higher.

CLARITY:

Schwanke-Kasten Jewelers tell shoppers to choose clarity grades of SI1 or higher as the integrity of the stone is not compromised as well as the aesthetic.

Green Diamonds | Schwanke-Kasten Jewelers

Gemologists rank green diamonds as among the most rare of the naturally colored diamonds. These marvelously beautiful and unique diamonds have been exposed to cosmic radiation over its million year formation. Other colored diamonds tend to have an additional element such as hydrogen as an inclusion. Please note, holding a green diamond will not make your finger fall off as the radioactive half-life has long since passed by the time it has been found. Diamonds with the natural colors of green, blue or red account for less that 0.07% of all diamonds examined by the GIA.

Green Diamond Formation

As we mentioned before, green diamonds form due to radioactive materials being present during its formation. Moreover, these materials could be uranium or thorium. Geologist have concluded that radiation penetrates the diamond crystal and can knock electrons or carbon atoms out of the specific crystal lattice. This often appears as a shallow “green” skin on the outside of the diamond, but uniform green throughout the diamond can exist although it is much rarer.

Furthermore, because electrons and carbon atoms are displaced in the crystal lattice, the way light enters and is refracted is affected. Hence the green portion of the visible color spectrum is reflected while the rest are absorbed and gives the diamond that appearance.

Additionally, diamonds can also have structural defects due to the presence of nitrogen, hydrogen or nickel atoms that may give the diamond its green appearance. However, natural irradiation is much more common.

Fancy Color Scale:

As for all natural colored diamonds, they follow a similar color grading scale: faint green, very light green, light green, fancy light green, fancy green and fancy intense, vivid and deep. For green diamonds, the more intense, vivid or deep the natural color is, the more expensive the stone is.

Diamond cutting:

As we mentioned before, often times green diamond color is very shallow, so this presents diamond cutters with a problem. How to maximize the natural green color in an exceptionally rare diamond.

Famous Green Diamonds

In fact, Christie’s Auction sold the Aurora Green diamond in 2016 for $16.2 million. The sale made it the most expensive green diamond as well as the largest Fancy Vivid Natural Green Diamond.

Marquise Diamonds

One of the most unique and definitive engagement ring diamond cuts are marquise diamonds. Jewelers and fans also refer to marquise cuts as football cuts, cat-eye cuts and boat cuts because of the highly elongated elliptical shape. This 58 faceted diamond cut is actually a vintage style and looks great on long, slender fingers. Furthermore, this romantic cut breathes an aristocratic air and carries a royal pedigree.

According to the legend, marquise diamonds date back to the 18^th century where “King Louis XV commissioned a jewelry to design a diamond cut that resembled the lips of Jean Antoinette Poisson, his mistress”. Furthermore, these diamonds also signify a rank just below duke, where individuals would actually wear these diamonds to signify said rank.

Additionally, gemologist originally design marquise cuts for diamonds, however jewelers now use these cuts with emeralds, rubies and sapphires.

Marquise Diamonds – TIPS

Marquise cuts are a fairly extreme cut when it comes to diamond cuts, so they are susceptible to chipping, so you may want to look for a mounting with protective prongs along the ends of the diamond.
A higher cut grade is important for the marquise diamond. Typically, elongated shapes tend to form a bow tie effect in the middle of the stone. Additionally, the symmetry of marquise cuts are very important.
One noticeable benefit is that marquise cuts tend to make the center stone look larger.

Do you like marquise diamonds? You know who else does too? Victoria Beckham, aka Posh Spice, Ashley Simpson and THE Catherine Zeta Jones.

Yellow Diamonds – Colored Diamonds

Enter into the exciting and highly exclusive world of fancy colored diamonds, where the traditional notions of diamonds being colorless shatters that concept. The first color diamond Schwanke-Kasten Jewelers will explore with you, is the yellow diamond; also known as the canary diamond.

Yellow Diamonds – A Canary Delight!

In the Superman comics, the hero crushes a lump of coal (carbon-based material) so hard that it produces enough heat and pressure to form a diamond for Lois Lane. While coal, under immense heat and pressure does not create diamonds, although they possess similar atomic makeups. However, when nitrogen enters the rigid structure of the composition of diamonds, they absorb blue light and give off a yellow shade in the visible light spectrum. The amount of nitrogen present in a yellow diamond will affect how light or dark the color is. Moreover, this logic of wanting more nitrogen, an impurity, naturally present in a yellow diamond is the opposite of a flawless white diamond. Additionally, gemologist give recognition to fancy color yellow diamonds a secondary hue such as orange or brown.

Yellow Diamond Engagement Ring from Schwanke-Kasten Jewelers

The GIA grades yellow diamonds slightly different than traditional white diamonds. Diamonds Pro sums it up nicely, “if the white diamond color scale [D – Z], were to continue past Z – all the way to a rich, yellow color – you’d have a Fancy Vivid Yellow Diamond”. Essentially this means that the best quality yellow diamond will be fully saturated with yellow and have no traces of whiteness.

Colored Diamond Scale:

Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid/ Deep/Dark

Gemologists estimate that one out of about every 10,000 carats of diamonds are a natural colored diamond. Furthermore, 60% of those natural colored diamonds are yellow. So, while they are common among natural colored diamonds, they are still exceptionally rare among the grand scheme of things.

Princess Cut Diamonds

Your true love is your princess; it’s only fitting to propose your undying love for her with a princess cut diamond engagement ring? This beautifully and interestingly square cut diamond is actually the second most popular style of diamond cut, below round but above cushion! At Schwanke-Kasten Jewelers, we decided to share with you all there is to know about princess cut diamonds

Princess Cut Diamonds History:

Surprisingly, diamond cutters have been only creating this style of cut for around 40 years to 50 years. Although it is hard to pinpoint, gemologist argue that a man named Basil Watermeyer created the cut as the Barion Cut in the 1970’s, however this was a combination of an emerald cut and a marquise cut. Others point to Arpad Nagy, a London Based diamond cutter, who created the what was then known as the “profile cut” back in 1961. started seeing demand for this style around the 1970’s. Israeli diamond cutters, Betzalel Amber and Israel Itzkowitz popularized Nagy’s cut several years later under the name Princess Cut, which was a “fancy French inspired cut”.

The Cut:

The princess cut was designed to have a modern, clean and feminine look to it. It is actually a modified square cut stone. Typically, princess cut diamonds appear as square, sometimes rectangle. On the profile, the stone has an inverted pyramid shape with four beveled sides. These stones typically have between 60 to 70 facets. Furthermore, because they retain, on average, 80% of the original rough stone, they are prone to having more inclusions than a round brillian cut. Which is not a negative, this allows the uniquely cut ring to have a very interesting and gorgeous light play to it!

The Cost:

Because Princess Cut Diamond only lose 20% of the rough stone when being cut (compared to 40-50% of a round diamond) they are a less expensive cut when all other factors are held constant (i.e. the 4 C’s).

Similar Cuts:

Cushion Cuts – have larger facets than princess cuts which increase their brilliance and highlight the clarity. However, they do not have as sharp of a sparkle and have an older, more vintage feel. Furthermore, they do not have as sharp of edges as princess cuts.

Round Brilliant – The most popular style of ring tends to look bigger when comparing the same carat weight stone. However, due to the cutting process, they are more expensive when all factors are held constant.

Asscher Cut – Similarly cut to a princess cut but with step cuts (a commonly found on emeralds, hence the name, emerald cut).

In fact, halo rings can be traced back to the Georgian era in Europe (1714-1837), where round diamonds and pearls were surrounded by smaller stones. During the Victorian era (1837 – 1901) the style grew even more popular with the rise of colored gemstones as engagement rings. Finally the modern sense of a halo ring arose during the Art Deco Movement.

Colored Diamonds – Natural Blue

It is a well-known fact that diamonds are among the rarest gemstones on Earth, naturally colored diamonds are even more so. So much so, that gemologists and geologists are still learning about how diamonds obtain color. The Gemological Institute of America (GIA) just published a report on blue diamonds. The study, conducted by GIA, took place over two-years using 46 blue diamonds submitted to the GIA.

Colored Diamonds – Blue Diamonds, A GIA Study

Evan Smith, a Lead Researcher at GIA, estimates that 0.02% of mined diamonds containing the trace element boron. Scientists largely conclude boron is responsible for natural blue diamonds color. This explains why in recent auctions, blue diamonds are fetching record prices. Moreover, finding these diamonds with natural, solid inclusions is even harder.

The Process

Gemologists concluded in this article that blue diamonds form an estimated 4 times deeper in the Earth’s mantle (most form between 93 – 124 miles below in continental plates brought up by Kimberlite eruptions). Researchers hypothesize diamonds fuse with boron in the sublithospheric mantle (superdeep) from oceanic rock. Furthermore, they state oceanic rocks are subducted 410 miles or deeper over a billion years by plate techtonics!

In addition, geologists make inferences from inclusions in these diamonds. This information tells gemologist about the surrounding minerals and known locations of said minerals.
