We have evaluated and summarized the following for grading:

A gem’s value is primarily based on its color. Here are the basics you need:

Color of gems

There are three primary colors (red, blue, yellow) and three secondary colors, which are the result of mixing primary colors (purple, orange, green).

Nature often displays tertiary colors, such as red-orange, yellow-green, or blue-violet, which are a primary color mixed with a secondary color.

When a color is mixed with gray, white, or black, we need the (overlapping) definitions of saturation, hue and tints.

Saturation

Saturation expresses the attribute of perception of gray of the same lightness. All grays have zero saturation. Theoretically a 100% saturation means there is 0% gray in a color.

Hue

Hue is color perceived to be red, purple, yellow, green etc., meaning white, black and gray have no hue.

Tint

A color mixed with white is a tint. A tint is lighter and less saturated than a color without the addition of the white.

Color Grade and Tone

Color grade describes the strength of the main color compared to other colors visible in the stone.

A 100% color grade in blue for example would imply that there are no other colors (like purple or violet) visible in the stone.

Color Grade

Excellent: 1-2

Very Good: 3-4

Good: 5-6

Fair: 7-8

Poor: 9-10

The color grade is simply based upon the purity of primary color. For example, the greener the emerald, the redder the ruby, or the bluer the sapphire, the lower the numerical grade on an AGL scale. The reason the 3.04 sapphire is a 3.5 in this sample is the fact the stone has 65% blue as its primary color. It is that simple. The less primary color, the higher the numerical color grade. For example, a 60% primary color would probably be graded a 4 color.

The color scan will generally break down into three perceived colors that total 100%. In the sample, the sapphire is 65% blue, 20% violet and 15% green.

If there was also no gray in the stone, we would have a 100% saturation with a 100% color grade, but such a stone has never been found.

Generally the rule applies: the purer the color the higher the grade. But grade is nothing without tone:

Color Tone

Any color grade has to be seen in combination with tone.

In the extremes a colored stone could be white (light 5) or black (dark 95) with just a hint of color.

Tone Scale

Very Light: 0-20

Light: 25-35

Light-Medium: 40-50

Medium: 55-65

Medium-Dark: 70-85

Very Dark: 90-100

Basically, tone describes the lightness or darkness of a gemstone. Color considered alone without taking into account the tone will lead to errors in interpretation. If a stone is too light in tone, the color will not be rich enough. Conversely, if a stone is too dark, it will sacrifice transparency and brilliancy.

Raw Material:

There are various kinds of gemstones like ruby, emerald, sapphire, amethyst, citrine, aquamarine and many more. These gemstones are found in different parts of the world and are imported by the suppliers and exporters direct from the mines as rough stones. These rough stones work as raw material for further processing.

Shape and size:

These rough edged stones are further decided to convert into shapes like oval, round, square, faceted, chips, smooth etc. and size as per the requirement.

Cutting and polishing:

The skilled craftsmen in the manufacturing unit cut and polish the stone using modern machines.

Most however, are cut and polished for usage as jewelry. The two main classifications are stones cut as smooth, dome shaped stones called cabochons, and stones which are cut with a faceting machine by polishing small flat windows called facets at regular intervals at exact angles.

Stones which are opaque such as opal, turquoise, variscite, etc. are commonly cut as cabochons. These gems are designed to show the stone’s color or surface properties as in opal and star sapphires. Grinding wheels and polishing agents are used to grind, shape and polish the smooth dome shape of the stones.

Gems which are transparent are normally faceted, a method which shows the optical properties of the stone’s interior to its best advantage by maximizing reflected light which is perceived by the viewer as sparkle. There are many commonly used shapes for faceted stones. The facets must be cut at the proper angles, which varies depending on the optical properties of the gem. If the angles are too steep or too shallow, the light will pass through and not be reflected back toward the viewer. The faceting machine is used to hold the stone onto a flat lap for cutting and polishing the flat facets. Rarely, some cutters use special curved laps to cut and polish curved facets.

Jewelry Making:

Finally these gems are used for making beautiful Jewelry. There are many kinds of jewelry tools that help to connect the beads and metals for making necklaces, rings pendants, earrings etc. Silver, Gold and Platinum are mostly used for making jewelry with semi precious and precious beads.
