Guide To Different Gemstone Settings

With over a hundred gemstone groups to choose from and thousands of colours to pick, there is only one thing that comes to rescue when you are looking for an immaculate personalized item for collection. Simple gem settings like halo, paves and prongs have been in the gemstone market for centuries and still continue to rule. If you are looking for an engagement ring or a ring for men, you should be able to identify and distinguish between different gem setting types available in the market.
Here is how different gems are set in distinctive pieces of beauty and grace.

  • Prongs and Solitaire settings

This is the engagement ring gem setting preferred for a single stone encrusted or fixed on a metal band or ring. Prong setting for diamonds, rubies, amethyst, garnet, sapphires and topaz is very common as it folds the single stone in place tightly without using too much metal.
Prongs are claw-like holders that can be further classified as:

  • Pointed prongs
  • V-shaped
  • Flat
  • Hooked

V-shaped prong gem setting features exclusively in princess-cut solitaires. It allows more light to pass through the gemstone, magnifying the radiance and brilliance many times over.

  • The Tiffany

The Tiffany gem setting model was conceived by the famous gem makers, Tiffany & Co. in 1886. It is a special type of six-prong gem setting that features a discrete knife-like edge over the shaft and the prongs. It is a patented gem setting exclusively to the brand.
Bezel Setting
Bezel setting for gems is undoubtedly the most preferred look for modern day buyers, especially those who are looking for light coloured stones. It is easy to handle and gives sturdy protection to delicate gemstone settings. The metal rim encircles the gemstone from all sides, and secures it tightly. The rim prevents the rock from three things:

  • Deposition of dirt
  • Scratches due to uneven setting
  • Unsettling of the stone even in thinnest of rim
  • Tension Setting

Tension setting is used for the gemstone when the craftsman wishes to give it a suspended look. The gem rests on the metal band as if it were suspended across the two faces of the shank. It is achieved through lasers and is a high-precision gem setting technique. The band usually has thin grooves so that the gemstone is tightly secured at its place due to the tension of the metal band.
It is comparatively cheap despite its elaborate and complex setting style. It can be used as an added feature even with regular gem setting looks like bezel and pronged ones.

  • Channel Setting 

Channel setting is done for smaller and thinly cut gemstones. It is often done to secure smaller gems set on a band in series. It is very similar to what a flush setting looks like. The gems like rubies, diamonds and topaz are set closely together over the grooves on the channel. Popular styles like stacks and bands are used for thin gemstones as they can’t be set in prongs and bezels.

Four, Six and Multiple prongs

Four prongs is a very popular form of gem setting that is done on lighter stones. It is employed for gems to allow maximum light refraction.

  • Princess cut
  • Medicine wheel cut for sapphire

It has multiple claws, usually in the series of 2s, 3s and 4s.

Full Bezel and half bezel

It is a royal gem setting style that is done on centre stones that are deeply encrusted into a combination metal or any other material. It protects the gemstone that are embedded into and encircled by metal. Emeralds, amethyst, garnet and turquoise are set in full bezel and accommodate shapes in square, oval and flat faces.

Semi-bezel is exclusively made for diamond rings weighing more than 4 carats. It allows maximum light penetration at all angles as compared to the same stone set in full bezel. Conventionally, bigger the gemstone, greater are the chances that it would be set in semi bezel.

Flush sets

Flush set is used for gemstones of darker hue like garnets, amethyst, lapis lazuli and onyx. Moonstones, rubies, cat stones and diamond are other rocks that are conveniently accommodated in flush sets. It is styled on bands and pendants slightly lower than the surface of the base material to protect them from damages and scratches. They resemble an encrusted wall.

Pave sets: Conventional and Mille grained

Gemstones paved on a metal base are placed very close to each other and separated by thin frames. The little beads of metals keep the smaller gemstones from detaching under force or fall. It also allows adjustment of gemstones when the metal expands due to heat. It is preferred for diamonds and rubies cut in bead or cushion sets.

Pave sets with mille grains are done for beaded gemstones to harmonize with traditional paves. It is usually employed for diamond rings set in royal antiquated designs.

  • Nacre
  • Bone

Pearl, obviously is the most fascinating non-mineral organic gemstone in the list.

  • Natural and Artificial

From a collector’s point of view, this is the most basic classification of gemstones. It is not that hard to identify an artificial gemstone from the natural ones if you understand the physical properties well. Artificial are often placed in the categories of refined, treated gemstones. Owing to the improvement in technology and chemical products, it could be a difficult task to distinguish between an artificial and natural stone if you are buying it for the first time.

Some of the popular artificial/ synthetic gemstone varieties belong to:

  • Corundum
  • Zincite
  • Citrine

How Concave Cut Gemstones is made?

There was a time when gem cutters sliced the gemstones as cabochons. The concave cut gemstones have always been very popular since 12th century when the concept of faceted rocks came into the picture. Improved machining tools and techniques since 16th century made it possible for the gem cutters to develop horizontal cutting wheel that created elaborate designs and geometric schemes. Concave cut gemstones in recent times have been produced using 3-dimensional LASER Cutting tools for precision touch.

Here are 5 enticing facts about the gemstone cutting technology used to manufacture them.

The Technology: Concave gemstones in facet cut

The flat symmetrical cut made on the gemstones to achieve 58 facets was always in a vogue. Richard Homer redefined the way gems could be cut to create brilliant effects. Though Homer is believed to be the father of concave cut gemstone idea, it was American lapidary artist Douglas Hoffman patented the technology of producing concave cut gemstones using 3-D.

Concave cut: Why it is made

The gemstone is cut into cone-shaped with 3-d facets with a distinct length and breadth on the surface. The pavilion facets are often cut in concave curves with flat facets sitting over the crown. It results in brilliant reflective patterns, particularly when the gemstone is viewed from top.

One of the advantages of cutting the gem into concave shape is that the light is evenly reflected through it. It creates a homogenous effect unlike any other cut.  The glow exudes from the internal structure and radiates a more uniform blush.

Moreover, the concave cut is a 3-D cutting method. It results in equal radiance when viewed from all angles. It creates depth on the conical facet of the gem resulting in added brilliance and alacrity from commercial point of view. Using the concave facet cutting technique minimizes hot spots from appearing when manufacturing fancy shapes like opal, pear and marquise. It is also the best way to eliminate the colour zoning effect that often mars the light coloured gemstones of bigger size.
Third advantage of having a gemstone cut in concave pattern is that even the smallest of light falling on it is exuded brilliantly. It automatically translates to higher likeability.
Cost of cutting a gemstone in concave style is more economical and time-saving than other methods.

Limitations of using concave cuts

Not all gemstones available in the market are suitable for concave cut. As a thumb-rule, only large sized concave gemstones are known to emit brilliant results when compared to the smaller ones. Also, if the gemstone is light in colour, it is preferred for concave cut over darker shades. Mathematically, using the concave facet cut enhances the colour tone by 25 percent.

Gemstones that transform beautifully when given a concave cut are:

  • Quartz
  • Citrine
  • Topaz
  • Fluorite
  • Aquamarine
  • Amethyst

Gemstones that are least preferred for this cut are:

  • Sapphires
  • Rubies
  • Red Spinel

As expertise improves, concave gemstones are likely to rule the market in coming years.
