Justin K Prim is an American lapidary and gemologist living and working in Bangkok, Thailand. He has studied gem cutting traditions all over the world as well as attending gemology programs at GIA and AIGS. He is currently working on a book about the worldwide history of gemstone faceting.
How do you facet a gemstone?
Faceting methodology consists of mounting a gem crystal on a metal dowel, (dopstick), which fits into a quill, then rigidly addressing the Height-Angle-Index triangle with the faceting machine, and touching the locked-in-place crystal to abrasive laps in two sequential operations, faceting first the top (called the “
What is a facet on a website?
Facet Joints of the Spine's Anatomy. One pair faces upward (superior articular facet) and one downward (inferior articular facet). There is one joint on each side (right and left). Facet joints are hinge–like and link vertebrae together. They are located at the back of the spine (posterior).
Polish the top of the cut gem against the polishing lap. Grind the outlines of the stone to shape the girdle. Use a 1200 lap disc on your faceting machine to cut the circumference (girdle) of the gem. Set the angle to 90 degrees so you can make symmetrical cuts. Don't lock the index wheel on the machine so you can move it freely and have more control over cutting.The outline you cut will depend on which shape you've chosen.
This could be a feature as simple as list and grid view modifiers. As a disclaimer, you will need one type of browsing preference crawled for Google to index the content. However, you will want to either disallow, or set the other versions of browsing as a canonical to the preferred indexed copy. If you answered yes to both of these questions, you have a facet category, and the links and content should be indexed.

For More information on AJAX Faceted Navigation see this post from Mike Pantoliano about Building Faceted Navigation That Doesn't Suck. I've talked to some of the best SEOs in the business and there is massive confusion and misunderstanding about facets, filters and sorting. There seems to be a misconception that all options that appear on the left hand side that allow users to narrow down their search for products are "faceted" nav. Your post did an an excellent job of explaining that these choices are a combination of facets AND filters and that some combinations are indexed and some aren't. The infamous robots.txt file can help you remedy a situation, but only if your filters have a defined path.
Five Gems Worth More than Diamonds
I recently worked with a Magento website to get rid of some of the issues they were having with indexation and it worked really well. Unfortunately they couldn't afford the development of AJAX navigation for the facet categories, but we did solve their problem using the robots.txt file.

What are gem cutters called?
Behind every exceptional piece of jewelry are extraordinary gem and jewelry experts known as "gemologists." Simply put, gemology is a science that includes intense academic study of diamonds, gemstones, pearls, and precious metals.
After cutting this facet, you have to pre-polish and then polish it. Both of these steps will remove more material.
These are filters that can easily be marked up in URL configuration to not be crawled. I would encourage anyone who is going to use this method to watch the video on configuring URL parameters from Google. It's quite helpful and can help to avoid making scary mistakes. It honestly just depends on what options you have to manipulate the URL and the categories, but still remember the rule of three.
Observe HAI on every facet and you’ll achieve the 4 P’s every time you cut a stone. As for the supplementary heady stuff concerning proper angles, conversion of notch numbers from one index gear to the next, reflectivity, etc., well, that’s a cinch, too. All three HAI controls (mast, quill, index wheel)are routinely locked in during setup before a faceter even starts to cut. As a result, the faceter needs only “patience,” the ability and mind set to hold the locked-in-place stone against an abrasive wheel and watch the progress. Put metal polish on the cloth and rub each facet of the stone against it.
- They’re rare, unusual, and seem to imbue their users with a certain spiritual enlightenment that allows them to cut very nice stones quickly.

How do you cut gemstones?
To cut hard gems, use a faceting machine to grind them into the shape you want. If the gems are softer, like pearl or amber, you can use sandpaper and water to shape the gem. When picking a shape for your gemstone, choose one that's similar to the current shape of the stone so you don't waste a lot of it.
Most Briolettes are cut from white rough, but colored diamond Briolettes, especially fancy and canary yellows, are increasing in demand, followed by cognacs and other champagne colors. The cut is also very popular for color gemstones. A stones refractive index is determined by directing light into the gemstone and then measuring the speed light reflects or refracts off its facets. The numerical result is calculated by comparing the speed of light in air vs. the speed of light in the gemstone. Faceted search has become a popular technique in commercial search applications, particularly for online retailers and libraries.
They’re rare, unusual, and seem to imbue their users with a certain spiritual enlightenment that allows them to cut very nice stones quickly. Rose Cut Diamonds are different than the traditional 'Brilliant Cut' diamond we know in this modern era. With anywhere from 3 to 24 facets, a Rose Cut Diamond resembles the shape of a rose bud. In general, they are flat at the bottom and creating a larger surface area for the stone’s brilliance. Magento would work awesome with this guide.
Lower the head as needed until the crown break facets create a level girdle and come together in the center. Then, cut the remainder of the sequence, checking your progress regularly. The procedures for cutting the crown are nearly identical to cutting the pavilion.
Briolette diamonds are found in antique and estate jewelry from the Victorian, Edwardian and Art Deco eras. Briolettes are one of the earliest diamond cuts. In or about 1476 Lodewyk (Louis) van Berquem, a Flemish polisher of Bruges, introduced absolute symmetry in the design of facets. He cut stones in the shape known as pendeloque or briolette.
An increasing number of enterprise search vendors provide software for implementing faceted search applications. Facets correspond to properties of the information elements.

The French developed this type of jam peg (known as Évention in French) with the mechanical stick, and this is their latest version. The machine boasts an electric motor (as opposed to the traditional hand crank).
The designs being speed cut have high symmetry. No ovals, hearts, marquises, pears, or other complicated designs. They require a minimum amount of angle changes. Changing the faceting machine settings slows down the work, especially if the angles aren’t simple.
The head has 17 or 33 notches, giving you a wide range of preset angles. If you need to go in between the preset angles or “cheat” slight left and right, there are knobs on the head to move to peg holes in both directions. The strength of this machine lies in its speed, due to the mechanical stick that allows you to cut facets very, very quickly. The Ultra Tec is probably the most well-known faceting machine in the world. Though frequently considered the best machine, every faceter who has ever lived has debated its merits.
Put a coarse to medium cutting lap in the machine, depending on how much material you need to remove. Gradually lower the height setting, cutting a progressively larger table. As the table grows, you may find it isn’t level, that it isn’t approaching the top of the main facets equally. The procedure for aligning the table is much like aligning for polishing.
Squirt a dime-sized amount of liquid metal polish on the cloth that's over the cutting board. Take the dry gem and rub it vigorously through the polish on the cloth. Use a faceting machine to preform the gem. Most uncut gems are oddly shaped so you may need to grind it down.
For most gemologists, their passion for jewelry and gemstones leads to a lifetime of continued curiosity and learning. Every gemstone is unique making gemology an endless source of inspiration.
