How to Identify Rare Gemstones: Understanding the Key Differences

Rare gemstones worldwide possess their distinct beauty, rarity, and identity. Gem identification involves examining and assessing a gemstone's chemical attributes and unique structure. This procedure necessitates gemological techniques and a skilled eye.

Once you know your gemstone is a natural one, you can evaluate its rarity with this guide and see this purchase as an investment.

In this article, we will go through the key differences that make rare gemstones stand out from the fake ones.

Rare Gemstones: Identification Through Observation

. The Color

An examination of the rare gemstones has to take place in 3 different positions; one will be with the top up, facing you, the other will be with the bottom up, and the last will be on its side, where you will see the girdle. Then examine to find what level of colour you have, this will be a range of very light to very dark color. Colour charts showing the levels of hue you can find in coloured gemstones will help to identify the appropriate hue you see in the stone.

. The Transparency

The transparency of gemstones can fall along the spectrum from opaque to transparent in terms of their ability to transmit light. Opaque stones do not transmit any light, but transparent ones enable you to see objects clearly when looking through them because they transmit light. A good rule of thumb is that rare gemstones are more transparent.

. The Cut

The different cutting styles of the rare gemstones may provide a small indication of their identity, since some stones are more often cut in certain styles. Any faceted stone with a shape other than round would be considered a "fancy cut" stone.

. The Phenomena

Both inside and outside of the gem's background color, there will be an optical effect that appears to either float or be a part of it. This is a result of the gem's interaction with the light within the gem's structure. By understanding some of the different types of phenomena, you can eliminate many options in your search for identification and specificity. Common examples of phenomenological effects are asterism, color change, play of color, chatoyancy, and orient. The added rarity of these stones and their overall appearance will enhance each stone's beauty and appeal.

. The Dispersion

When white light breaks up or is separated into its different constituent colors, this phenomenon can be seen visibly as a fire or colored light. To identify rare gemstones as opposed to simulated ones, one way to tell the difference between the two stones is to measure and observe the measurement of the amount of dispersion present in each gem. Fire quality in a stone can help to determine what the actual stone is and provide more information about its quality.

Common Differences Found In Imitations

. Orange Peel Effect

A feature that most rare gemstones lack is this effect. The orange peel effect describes a surface that appears uneven and dimpled, often observed on the reflective surfaces of glass and plastic replicas.

. Swirl Marks

Swirl marks, or flowlines, occur during the creation of imitation stone when the ingredients are insufficiently blended. They resemble curved stripes but tend to be coarser and less uniform than synthetic curved color banding.

. Gas Bubbles

Air bubbles can often be seen in what can be called faux stone, and they are more rounded and larger than those found in real or manufactured stones. The natural and rare gemstones do not have such bubbles. Large gas bubbles that are located near the edge or point of a swirled mark would provide a strong indication that the stone is fake. If several gas bubbles exist together in a small area of the stone, it will appear similar to a fingerprint inclusion, so be careful to compare the gas bubble size and shape with that of the other inclusions.

Rare Gemstones List

Some gemstones are among the most valuable and rarest in the world. These minerals are extremely scarce and hard to acquire, mainly because there are so few of them in circulation. Here is a ‘rare gemstones list’ to have a better understanding of their rarity.

. Painite

Until very recently, Painite was considered by many to be the most difficult mineral on Earth to find; only a handful of pieces had been discovered by man and recorded as existing before then.

. Red beryl

Red beryl is another elusive crimson colored gemstone, around 80 times rarer than regular emerald, that has only been discovered primarily within the state of Utah.

. Benitoite

Because of its vibrant blue color, the stone is an exceptional example of fire in gemstones and has exhibited greater fire than diamonds when produced from Benitoite's only known site in California.

. Alexandrite

One of the most loved gemstones due to its remarkable hue-changing abilities is alexandrite. This gemstone can display either an emerald green hue when viewed in daylight or a ruby red hue when viewed under incandescent light.

. Grandidierite

Grandidierite is one of the extremely rare gemstones and valuable bluish-green minerals because of its limited availability, but also because of its highly intense color. It is mostly found on the island of Madagascar.

A Final Word

Only authentic gemstones hold their worth today during purchase and also in the future at a potential resale. Most rare gemstones are worth even more and serve as an investment in the future, as well as a token of true love in jewelry.
