Read on and find out how to evaluate gemstone value!

Rarity

Rarity determinants include the availability of the material, the size, and the clarity. Smaller, rarer stones tend to fetch higher prices when compared with larger, more common specimens.

Furthermore, the origin of gemstone is also highly relevant. Valuable gems come from exotic and hard-to-access locales and are seen as more prestigious when compared with others. So, rarity should always be considered when appraising gemstones. A qualified gemologist should be consulted to get the current market value of a collectible gemstone.

Color

Another key element in evaluating the value is the color of the stone. Gemstones with pure, saturated red, blue, pink, and green hues typically fetch the highest prices. The more intense and even the color, the more valuable the gemstone will be.

Colorless gemstones with crystal-clear transparency are valuable, mainly when emitting a solid sparkle. Though considered pretty, gemstones displaying soft pastel tones lack the vibrancy that collectors look for when evaluating the value of a gemstone.

Clarity

The number, size, and location of inclusions in the gem determines clarity. It can affect the beauty, durability, and value of the gem. It can range from flawless or internally flawless to heavily included.

The fewer and smaller the inclusions, the higher the quality and greater the stone's value. Gemstones with eye-clean to very slightly included clarity are often considered valuable, especially if there is an intense saturation of color.

Size and Shape

Larger stones are often more valuable, as they are rare and unique. Shapes also affect a gemstone's value, as more symmetrical and difficult-to-cut shapes are desirable.

Shape and size can even interact to make certain stones more valuable. For example, a round and large gemstone may be more valuable than a similarly sized gemstone in an irregular shape.

Enhancement Techniques

Enhancement techniques are used to improve the appearance or value of a gemstone. These techniques alter, improve or mask a gemstone's desired look or quality. Examples of gemstone enhancement techniques include applying heat, using dyes, oiling, irradiation, or even glass and plastic treatments.

Collectors need to be aware of such techniques as appraising gemstone values depending on the stone's quality, clarity, and nature. They should become familiar with gemological terms. As these can help to identify enhanced gemstones, as well as assess their value.

Research reputable and experienced appraisers to evaluate different stones. They should also become familiar with the techniques and methods involved in gemstone enhancement. It's also vital for them to know how to spot fake ones.

For example, the stone amethyst is a strong reddish purple or purple with no visible color zoning. After enhancements, there may be some color changes. You can check this site for help on how to spot fake amethyst.
