Dichroic Glass beads
Dichroic glass beads are essentially beads made of Dichroic glass. Here glass is coated with several thin layers - either metal coatings or others in a vacuum. These beads have the ability to reflect and transmit light giving rise to a beautiful play of colors.
A mineral that exhibits one color when viewed from one angle but a different color when viewed from a different. In beads it usually gives them a shimmery, iridescent, metallic look like molten metal.
A glass which contains ultra-thin layers of aluminum, chromium, silicon, zirconium or the metal alloy titanium. The colors are almost holographic in appearance. Addition of the various elements is what produces the bold and dramatic colors. Colloidal Gold may also be added.
Dichroic Glass Beads
A type of lampwork bead with a thin film of metal on its surface, allowing it to change colour as it reflects light.
A reflector that projects light forward while deflecting heat backwards, toward the socket, so the light beam itself is cool. Quartz halogen incandescent light bulbs frequently contain an integrated dichroic reflector which is slightly open around the base of the bulb.
dichroic Of two colors; the characteristic of a transparent substance to divide refracted white light into two distinct rays.
diffraction The modification of white light as it breaks up into the color spectrum.
A property, peculiar to crystals, of reflecting light in two different colors when viewed from two different directions.
Dichroic Glass - this is a type of glass which contains multiple micro-layers of metal oxides. This gives the glass reflective optical properties.
dichroic / dichroism
The property of having more than one color, especially when viewed from different angles. Many minerals are naturally dichroic. This effect can be artificially caused by a thin layer of a metallic oxides that is deposited on the surface of a material.
This incredibly beautiful glass of oily, rainbow iridescent colours is the result of super high-tech aerospace engineering. Multiple layers of metal oxide are applied to a base coat of glass to the thickness of approximately 1/40th of a sheet of paper.
Dichroic gems (like corundum) show two different colors while trichroic gems (like iolite) show three.
Pleochroism will not be observed in SR gems, nor in DR gems when looking through an optic axis direction.

The faceted orange-brown dravite in the photo above (right) is cut so that the c-axis, which is always as saturated, or more saturated than the a/b-axis, comes out of the stone perpendicular to the table.
Dichroic coated glass transmits some wavelengths of light and reflects others, giving it a distinctive metallic appearance.

Strongly dichroic with the ordinary ray having a darker color
Amethyst is dichroic, showing a bluish or reddish purple tinge when viewed from different angles. Its colour is most often caused by iron impurities, though it can also be coloured by natural radiation exposure.
In a doubly refractive crystal, a light beam reflects two different rays. The eye cannot
normally see both rays at the same time, but by moving the stone, the eye will observe
both rays. The result? The stone exhibits one of two or more different colors (or two or ...
SPHENE - A Dichroic Gem
Sphene is a beautiful yellow green to green gemstone which has a very high dispersion. This means that the light which goes into the gem is broken down into a rainbow of colors, similar to diamond.
Axinite: Is a dichroic, boro-silicate of aluminum and calcium, stone that is lustrous and has translucent as well as transparent varieties.
Tourmaline is a dichroic gemstone that comes in many, many different colors; it also appears to have different colors depending on the angle at which it is seen. Tourmaline's name comes from the Sinhalese word "turmali," which means "mixed.
strong dichroic. distinctive pistachio green. Epidote is the principal member of a group of silicate minerals that occur most commonly in low grade, calcareous metamorphic rocks and also in igneous rocks, where they have altered from feldspar, pyroxene, and amphibole minerals.
Axinite is dichroic. Axinite has a hardness of 7 and a specific gravity of 3.3. Axinite is a boro-silicate of aluminum and calcium. It is used only as a mineral specimen and not in jewelry.
This gemstones is strongy dichroic; although Benitoite is blue when viewed from most directions, it appears colorless when viewed in a single direction (the c-axis). Some unusual Benitoite is blue, but pink or orange when viewed through the c-axis.
The most useful is the MR-11 bulb which has a built-in dichroic reflector to focus the light forward. There is a larger bulb with built-in reflector, the MR-16, but it is too big unless you are going to mount the lights in the ceiling or more than four feet from the minerals.
Many minerals (like rubies and axinite) are naturally dichroic. This effect can be artificially caused by a thin layer of a metallic oxides that is deposited on the surface of a material.
Blue fluorescence under short wave UV. Strongly dichroic. Named after the local (San Benito County) where it was first found (1907). This is the only site on earth where it has been found in place.

As tourmaline is the most dichroic of gemstones, a strong multicolor effect is to be expected. However, perhaps due to its unique chemical composition and its distinctly dark tone, multicolor effect is rarely observed in the chrome green gemstone.
It is a dichroic gemstone and appears to have different colors depending on the angle at which it is seen. Lighter colors are considered more valuable than the darker. It ranges in color from pink to green to red (Rubellite) to purple to blue-green (Indicolite) to colorless (Achroite) to black.
One of my favorites ended up being the dagger fringe earrings - made with dichroic cabochons, it turned up being delicious. It's one of the components that kind of called out to me (I could hear the cabs pleading to be made into something pretty).
It is strongly dichroic in pink and blue. All are said to have faded after a short exposure to light, and the color can be restored by irradiation in this particular type of aquamarine.
These typically consist of an excitation filter selecting the range of excitation wavelengths, a dichroic mirror, and an emission filter blocking the excitation light.
It has both transparent and translucent varieties. Axinite is dichroic. Axinite has a hardness of 7 and a specific gravity of 3.3. Axinite is a boro-silicate of aluminum and calcium. It is used only as a mineral specimen and not in jewelry.
Abalones are members of a large class of mollusks that have one-piece shells. These shells have a dichroic, tortoise-like appearance. Abalone is the popular name in the United States for a univalve gastropod mollusk of the genus Haliotis.
An effect where the properties of diffraction in a stone cause it to look a different colour depending on the angle you observe it from. Many stones are dichroic or trichroic.
Plique a Jour
Literally 'glimpse of day'. Transparent coloured enamel windows which allow the passage of light.
I left with a gemstone doughnut, a watch face, some Swarovski crystals, lots of seed beads, a dichroic cabochon, some Bali beads, Beadsmith Fireline, a tube of G-S Hypo Cement, and a package of Bead Stoppers (why didn't I think of inventing that).
Bi-colored and multicoloured tourmalines may be green at one end and pink at the other, watermelon tourmalines are green on the outside and pink on the inside. Some stones are dichroic meaning they appear to change color when viewed from different angles.
