    treatment

    Stone treatments are sometimes used to change the appearance of a stone. For example, heat treatments are used on nearly all sapphires and rubies because it brings out their vibrant color.

    (H) Heating: The stone has been treated with high heat to enhance or change its color. This technique is permanent and is used on a large amount of fine quality gems.
    (O)Oiling/Resin: Typically used for emeralds, oiling and resin filling helps to minimize the appearance of cracks and enhances the stone's liveliness.
    (I)Irradiation: Irradiation has been used to deepen or change a stone's color entirely. The treatment is stable and permanent.

  • Quality

    Quality

    Unlike diamonds, gemstones are given an overall quality grade based on a variety of factors. These characteristics include color, color consistency, clarity, and cut quality.

    AAA-grade gemstones: considered to be near-perfect, with a color that has high, well balanced saturation, a quality cut, and few to no inclusions.

    AA-grade gemstones: well cut, slightly less vibrant than AAA stones, with very good brilliance and polish. May have slight inclusions.

    A-grade gemstones: less saturated in color, may have moderate-heavy inclusions.

    Commercial-grade stones: are usually cloudy with poor color quality, not suitable for precious gemstone jewelry and not sold by Pratiksha.

    Faceting

    Designed to show the brilliance of a stone, a gemstone’s facets are a series of geometrically arranged, flat surfaces cut on the stone. Some faceting styles include drilling, and sometimes gemstones are polished smooth into a cabochon shape with no facets.

  • Carat Weight(ct)

    Carat Weight(ct)

    The carat of a gemstone refers to its weight, and 1 carat is equivalent to 200 milligrams. Independent of a gem’s size, two stones with the same carat weight may appear slightly different in size. It’s important to understand and evaluate the relationship between a gemstone’s carat weight, color and cut to get the best value out of a stone. Choosing a gemstone that is a few carat weight points below your ideal carat (0.49 carats vs. 0.50 carats) can translate to significant savings.

  • gemstone clarity

    gemstone clarity

    Authentic gems vary greatly in clarity, as natural inclusions are much more present within certain precious stones. Emeralds, for example, often include visible inclusions that add character and evidence of authenticity. Clean stones are determined to not have any inclusions present to the naked eye.

  • Eyeclean %

    Eyeclean %

    A description of whether or not inclusions within the stone can be seen with the naked eye, expressed as 100% eyeclean, 90% eyeclean, or not eyeclean. 100% eyeclean means that inclusion(s) cannot be seen with the naked eye even after they have been located with a loupe. 90% eyeclean means the inclusion(s) are generally not seen by the naked eye and can be seen only after first locating them under a loupe.

  • Gemstone Origin

    Gemstone Origin

    As all gemstones are naturally occurring, it’s helpful to understand the geography of where certain stones are mined and discovered. Many stones are much more elusive and rare from certain parts of the world. Tanzanites, for example, are only found in one place in the world: Tanzania. Russian alexandrites are much more valuable than other alexandrites because they haven’t been produced for over a century.

About Opal

Because opal has the colors of other gems, the Romans thought it was the most precious and powerful of all. The Bedouins believed that opals contained lightning and fell from the sky during thunderstorms.

 

The look of each opal is wonderfully diverse between its background color, pattern, and clarity. This can make well matched pairs or lots of stones particularly valuable.

 

Opal (or “white” opal) is found primarily in Australia and Ethiopia.


Buying Tips

One of the most important component of an opal’s beauty is the size and arrangement of its flashes of color, called its pattern. Like the shapes you see in the clouds, play-of-color takes many forms.

 

Common terms for play-of-color patterns include:

  • Pinfire or pinpoint: Small, closely set patches of color
  • Harlequin or mosaic: Broad, angular, closely set patches of color
  • Flame: Sweeping reddish bands or streaks that shoot across the stone
  • Peacock: Mainly blue and green

 

As with any play-of-color, no matter what the pattern, colors must be bright for the stone to be valuable.

 

The cut of a fine opal should be symmetrical. If it’s a cabochon, the dome should be well rounded. Domed surfaces give the best play-of-color, and make the stone appear vivid from most viewing angles. If the cabochon is flat, it might be vulnerable to breakage, especially during setting into jewelry. If it’s too high, it might be hard to set in jewelry.

 

Given that opal can be fragile, it is often “assembled” as a doublet or a triplet. The doublet is a thin layer of opal cemented to a backing often composed of obsidian, dyed black chalcedony, black glass, natural common opal, or plastic. The triplet is a thin layer of opal cemented between a domed top of colorless quartz or clear glass and a backing of obsidian, chalcedony, or black glass.

Specifications:

Species :

The mineral group to which the gemstone belongs. Examples of species include beryl (emerald, aquamarine), corundum (sapphire, ruby), and quartz (agate, citrine, amethyst).

species Info
Silica

Refractive Index :

A measure used to demonstrate a stone's brilliance.

Refractive Index Info
1.400 - 1.460

Birefringence:

The difference between a stone's refractive indexes, if it has more than one. Colored gemstones with high birefringence may be pleochroic, meaning they change color depending on their orientation to the light (like a polarizing lens).

Birefringence Info
None

Specific Gravity :

A ratio of the stone's density to an equal volume of water. Stones with higher specific gravity are denser and therefore will be smaller in dimension than a stone with equal weight but lower specific gravity.

Specific Gravity Info
1.98-2.25

Hardness (Mohs) :

The hardness of a stone refers to its Mohs hardness, which places the stone on a 1-10 scale with talc at one, the softest, and diamond at 10, the hardest. However, the scale is relative to the other materials on the scale; while diamond is only one hardness higher than corundum on the scale, it is actually four times as hard as corundum in terms of absolute hardness.

Hardness(Mohs) Info
4.5-6.5
