Octagon Cut | Learning Guide
Octagonal and emeralds are sometimes very hard to distinguish. Seen from above, the octagonal cut with slightly cut off edges is actually no different from an emerald cut. If you look at the side profiles and see that the parallels are not at the same distances, the differences become obvious.
The octagonal cut, like the green cut, has bevels that run both at the top and bottom of the belt along its length. It is not like a round diamond cut that its caullet arrives at a point, but its faces on the Pavillon join along a spire, similar to the top of a rooftop on a hous.
Recently, contemporary octagonal styles with equally long sides (seen from above) have become more trendy. The large bevelled edge of the cut is perfect for the presentation of gemstones that have a great color and clearness, as the eyes tend to be pulled into the gemstone. There' s no exact cut standards, but almost all the gemstones we have been selling have 41, 49 or 57 beads.
Gemstone grinding is a manufacturing technique in which coarse, uncut gems become gems as we know them, so that they can be used in pieces of jewellery. The cut gives the stone a certain form and creates the real colour and brilliancy of the gemstone. Bottom are the many styles and forms that a editor would consider to give the best value to his client.
Gems can come in a wide range of forms, such as round, bulb, rectangular, octagon, ovals, triangle and cardioid, among many others. Any of these forms can be transformed into many different cut tings, according to how the jeweller uncovers the many aspects of the gem. As an example, the quadratic form can be converted into a princess cut, a radiant cut, an asscher cut and a couch.
Gemstones differ in the number and dimension of the bevels engraved on the stone surfaces. Also known as "Square Emerald cut", it is a mixture of exquisite print and green cut. Instead of producing a bright facetted design that emphasizes the fire of the jewel, the "step-cut" facettes in this cut maximizes the jewel's clearness.
In the newer release, the number of bevels rose from 58 to 74 and broader angles were used. Shaped long and square, baguette-cut gems are a favorite option for accented gems in the jewellery industry. The 14 facettes are grinded gradually along the edge and are reminiscent of a topless pyrramid.
Though not as hot and bright as a round cut, these bricks are cut to maximise clearness. As baguette production takes fewer polishes than other types of gemstones, it is very important to cut them correctly, as there are far fewer bevels to conceal any inaccuracies. In contrast to round rocks, their singular form allows baguette pieces to be placed side by side without any gap, which makes them indispensible in today's jewellery making industries.
Briolette cut is a stone in the form of pears or drops with 84 triangles that cover its whole area. For this reason, the briolette is the most hard to cut one. This cut is not bursting with fire and lustre like a round brilliant cut, but reflects all of its trigonal face.
Briolets are usually not assembled in heavier frames, so that more of the gem becomes apparent. Others, a noble metallic hat is attached to the top of the gem so that the triolette functions as a figur. Some even claim that the concept of briotilette derives from the words "brilliant", which means as much as lively, and "brignolette", which means as much as "dried plum".
In the 19th and 20th centuries, before the advent of more contemporary styles such as Round Brilliant, many briolettes were used in tiara and crown wear by royalty, especially during the Victorian, Edwardian and Art Deco age. Cabochons, also called "cab", are just facetless gemstones.
Traditionally cut cabochons are ovals in form, but any form can be cut in cabochons. The formed and buffed "en cabochon" precious stones date from the early Jewish, Grecian and Latin age. Indeed, this was the only gemstone that was available for a long period of use, apart from the use of precious stones in their original state.
Although most jewellers today still favour facetted gemstyles, certain precious stones are still cut "en cabochon". These are the ones where the particular properties of the precious stones can only be seen in the cabin. Others that can be cut into cabochons are those that are inherently non-transparent or have finite clarity, such as teal, blue-green, blue-green, yellow-green, orange, yellow, jade garnet and garnet; those that have a great colour but some imperfections on their surfaces; or those that are not very permanent.
As cabochons minimise the occurrence of scrapes, many jewellers decide to cut soft gems "en cabochon" so that they are not rubbed off when bevelling. Formerly known as the "Old Mine Cut" or "Old European Cut", this cut presents itself with approx. 64 facettes and features a quadratic base form with softly curved edges that makes it look like a sofa pillow.
Cushions may appear slightly ovate in form. Emerald Cut has the form of a rectangular from above, with cut edges. Approximately 50 facettes mean that this cut has fewer faces than round or square grindings. Colour tends to show very vivid in emerald-cut gems.
On brighter gems, this cut can shine with wider and more conspicuous flashing lights, with the lights jumping between the bright and deep surface of the gems as if looking into a mirror. Finally, this cut was also used for diamond and other precious stones.
Clients were particularly impressed by this singular and classy new styling, as its oblong form looks particularly complimentary on a pen. Cardiac cut is essentially a pear-shaped cut with a gap at the tip. The 59 faceted bevels can be very hot and sparkling.
Symetry is an important factor in the selection of a good heart-shaped cut gem. Seldom used as betrothal ring, heart-shaped gems are still a favourite option for jewel ryestones. It is another variant of the "step cut", in which the stones are worked with lines of broad, shallow, concentric facettes that look like stairs around the gem.
There are 53 different bevels in an octagon cut. Octagonal cut gems are perfect to represent the depth of colour of any stone. Also it shows any inclusion a stone can have, so it is important to look for gems that are particularly nice in colour and free of inclusion when looking at the octagon cut.
This oval cut was designed by Lazare Kaplan in the 1950s - early 1960s. Seen from above, it has an elliptic form and can be described as a combination of round and marquises. It is a modification of a 69-faceted diamond cut that gives the user the lustre and fire of a round gem in a truly original state.
The long outline is an added benefit as it gives the impression of a bigger gem and allows a digit to look longer and sleeker when worn. Renowned oval-cut betrothal bands embrace the breathtaking 12 karat elliptical ring that Kate Middleton got from Prince William, who was the property of his deceased dam Princess Diana; and an elliptical 5 karat ring that Katie Holmes got when she got married to Tom Cruise.
A pear-cut gem in the form of a shiny drop can be described as a mixture of an oval cut and a marquise cut with a tapering tip at one end. It' a kind of round brilliant cut and therefore has 71 different faces that nicely reflects the sunlight and brings out the colour to the full.
In 1458, the first pear-cut diamonds were produced by the Flemish polishers Louis van Berquem from Belgium. It is important to ensure a perfectly symmetrical shape when producing a pear-cut gem. Gems with a 6 tine cut need a specific 6 tine set to hold their delicate tip.
Although most females carry the pointed end of the pear-cut gem in the area of the nail, this largely depend on the selection of the person wearing it. A pear -cut ring's oblong shape extends and makes the wearer's fingers slimmer, making it an appealing option not only for ears and necklaces, but also for necklaces.
Peach cut wedding bands were carried by famous people like Katherine Heigl, Avril Lavigne, Bethenny Frankel and Jessica Simpson. The second most favoured cut is the quadratic cut, directly behind the round diamond cut. Actually it is known as " squares edited brilliance " because it is essentially a quadratic variation of the Round Diamond cut.
There are between 58 and 76 different aspects that make the sunlight rebound from its surfaces and make it a form with the greatest shine. The best way to underline its beneficial properties is to use lightweight, translucent gems. It has a square-cut stone that keeps 80% of the raw stone, while the round-cut stone only keeps 50%, making it interesting for clients and cutting tools as well.
This fashionable polish cuts the four edges of a squares or octagons in a single line instead of beautifully rounded off like a pillow polish. Offering the contemporary quadratic form without compromising the brilliancy and fire of a round gemstone. Known as "Round Brilliant", "American Ideal" or "American Standard".
The 57 facet cut is the most effective way to capture the lustre and shine of a gem. Over the years, the round cut has experienced many, many changes in order to best possible modify the facettes and to optimise the scattering of colour in a gem. The most remarkable round styles are the " Old Single Cut", "Rounded Single Cut", "Old European Cut", "Jubilee Cut", "Royal Cut" and "Basic Brilliant Cut" or "Ideal Cut", or the "Tolkowsky Cut", which was created in 1919 by the polar mathematical artist Marcel Tolkowsky.
With his doctorate in round brilliancy from the University of London, Tolkowsky established himself as the pioneer of cutting-edge cylindrical grinding. Initially designed solely for the use with stones, the Round brilliance cut is now also widely used for precious stones. Trillian cut gems have a triangle form.
You can round the sides slightly or cut them off evenly in three-sided steps. A round diamond, its 31-43 facetted, equilaterally -sided shape is known for maximizing luminosity and gemstones. When used as a solitary piece, the Trillian gem requires a special frame to help preserve its sensitive nooks.
Since trillian cut gems are flat cut, they are prone to creating the impression that they appear heavier than their given light. It is also known that the trillian cut minimizes the wastage of raw stone during the grinding operation. This, together with a truly refined and singular form, make trilliants an outstanding value, whether used as solitaires or as side pieces.
The cut unites the features of the two classical styles - cabochons and bevelled edges. While the top is vaulted in a combo-cut, the underside of the gazebo under the belt contains facettes. Because of its facettes, this cut still retains a certain radiance and provides the impression of deepness when looking into the middle of the gemstone.
Buff Top cut is a favourite for men's jewellery, possibly because the gem's sleek and shiny cupola is much less easy to scratch than the facetted gem surfaces and therefore provides greater strength.
