Gemstone and Shape
Gem Cuts and Styles - Bulk Gemstones
Gemstones are one of nature's most exquisite creations. Their brilliant shine, magnificent colors, and perfect shapes captivate the eye and heart. However, the godly appearance of a gemstone is not entirely natural. Most precious stones are enhanced before they are sold. When gemstones are mined from the earth, they are covered with impurities and have irregular shapes. These gemstones are then cut and polished to enhance their physical appearance, making them more appealing.
Tumbling and Polishing
Tumbling and polishing is the simplest and earliest method of enhancing a gemstone's quality and giving it a definite shape. In this process, a gemstone is placed in a tumbling machine, which moves it in a circular motion. The grit motion continues for several days or weeks until all the edges and surfaces of the stone acquire a smooth and polished round surface.
Why is a Gemstone Cut?
Gemstones are cut for several reasons beyond just achieving a specific shape. One major reason is to enhance the stone's shine. Simple tumbling and polishing do not produce a sparkle. To achieve this, multiple flat planes called facets are cut into the stone's surface. These facets reflect light, creating a sparkling effect. Cutting a gemstone enhances its outer appearance while preserving its chemical properties, significantly increasing its value by showcasing its unique characteristics and brilliance.
What is Gem Cutting?
Gem cutting, also known as lapidary, is the process of cutting and polishing gemstones to enhance their physical beauty, such as color and sparkle. This process is essential after gemstones are mined in their crude form, covered with unwanted particles and having a dull appearance. Gemstones are then transformed into brilliant, colorful, and perfectly shaped stones suitable for jewelry making.
Gemstone Cuts
Cabochon
The cabochon is one of the oldest forms of gemstone cuts. It is not exactly a cut, as there are no facets. Instead, the gemstone is tumbled and polished to achieve a smooth, shiny surface and then trimmed. Opals and moonstones are common examples of cabbed gemstones.
Old Mine Cut
The old mine cut is similar to the Mogul cut and the old European cut. Its primary aim is to achieve maximum brilliance with larger facets and a taller shape, giving gemstones a vintage look.
Step Cut
In the step cut, facets are added in horizontal layers resembling steps. This cut highlights vibrant colors and clarity.
Brilliant Cut
The brilliant cut is complex, requiring multiple facets at different angles to maximize sparkle. It has many variations, depending on the size and shape of the newly mined stone.
Barrion Cut
The Barrion cut combines the brilliant and step cuts, creating facets that form a cross-shaped pattern in the center of the stone.
Rose Cut
The rose cut features a round cabochon base with a faceted top in a triangular pattern. This cut has been popular since the 1520s.
Divine Cut
The divine cut is a variation of the brilliant cut, designed to increase brilliance and light refraction. The stone acquires a parachute-like shape with a flat, smaller top surface.
Checkerboard Cut
In the checkerboard cut, facets are made in a square shape, often paired with cushion-shaped gemstones for best results.
Eight Cut
The eight cut is a simpler version of the brilliant cut, with only eight facets made in accordance with the stone's center.
Ceylon Cut
The Ceylon cut is a mixed cut with sides cut in steps ascending to the center, similar to the brilliant cut.
Gemstone Cutting Tools
With technological
advancements, many tools have been developed to cut gemstones with precision and sophistication. A good cutting tool enhances a gemstone's clarity and intricacy without compromising its innate traits. Modern tools often feature polishing pads, grinders, angle scales, setting pins, faceting adjustments, diamond or silicon carbide tips, ease of use, and proper illumination.
How to Choose the Right Gem Cutting Machine
Choosing the right gem-cutting machine is crucial. Key characteristics to consider include repeatability, speed, accuracy, and reliability. A good machine should produce consistent results, operate at a suitable speed, cut accurately, and remain reliable over time.
Types of Gem Cutting Machines
The Jam Peg Machine
A traditional gem-cutting
machine with greater speed but less accuracy. It requires a longer time to master.
The Mast Machine
A technologically advanced machine used in developed countries. It offers high accuracy and is easy to use but has a slower speed.
The Hand Piece Machine
A balanced combination of speed and accuracy, easier to use and maintain, offering long-term reliability and producing brilliant gemstones.
