The more light a gem absorbs or reflects means it transmits less light through it. A translucent gem can transmit enough wavelengths of light that we can see light shining through it. A transparent gem is translucent and transmits light with little scattering. This allows us to see images as well as light through a transparent gem. Ulexite has an unusual form of transparency. In addition, it projects that image onto the surface closest to you.
Can You Measure Gemstone Transparency? However, gemologists normally use the commonplace meanings of opacity, translucence, and transparency in gemstone descriptions. A nqked range of transparency can exist even within a single gem species. Tourmalineslike these tumbled specimens, can range from opaque to transparent. Gemstone Transparency in Ultraviolet Light Nevertheless, we should make an important scientific distinction when discussing gemstone transparency. However, there are wavelengths of light beyond visible light, such as ultraviolet UV light. Some gemstones, such as diamondsare transparent into the UV spectrum.
Prices are influenced by the following factors: Better qualities are more rare than lower qualities of the same size see previous Jekstone. Bigger stones are more rare, and so Jemstone naked expensive per carat than the same quality of a smaller size. This is the great intangible. Market factors can dramatically affect price.

Over time, gem dealers have come to rely on skylight for their gem buying. Its major advantage is its strength, which ruthlessly reveals flaws. The quantity of light coming through even a modest-sized window is far greater than even the strongest, color-balanced fluorescent tube or tubes. Another factor appears to be the large radiating area, when compared with the most artificial lights. As a result, gems bought in the tropics will appear slightly darker when taken to more temperate climes. It is a slight, but nevertheless, noticeable difference. Surprisingly, north skylight or south skylight in the southern hemisphere is actually stronger on cloudy days.
Another factor is the Purkinje shift. In bright light, the eye is more sensitive to red; conversely, in dim light the eye is more sensitive to blue-violet light.
Jemstne the color of blue sapphires would be slightly enhanced in dim lighting. The question of north skylight. North daylight skylight, as opposed to direct sunlight has become the standard, because it produces the least glare, but blind adherence to such gemological dogma is just as bad as blind adherence to religious dogma. This is especially true the farther north one goes.

The opposite holds true for those who reside south of the Tropic nwked Capricorn in the southern hemispherewhere the nakrd glare is found using south skylight. Natural light is not constant in spectral composition, but varies according to latitude, time of day, cloud and pollution conditions and whether or not one is using direct sunlight or skylight. The Buddhist temple at Swayambunath, Nepal, silhouetted against a deep blue sky. It is obvious that such skylight would enhance the appearance of blue stones.
