This is a beautiful one of a kind necklace with Hemimorphite Druzy and Dichroic glass, set in Sterling Silver, on a really cool Diamond Bead sterling chain.

I have described below what the types of stones that I used in this piece are.

Size - 2.25 inches x 1 inch x .25 inch thick
length - 21 inches

This druzy is an incredible aqua blue on a white substructure, a totally amazing cabochon. If you have not seen this stone before it is really cool. This color is so rare in nature, and resembles the amazing color of the Carribean sea.

Hemimorphite, is a mineral which has been mined from the upper parts of zinc and lead ores, chiefly associated with smithsonite, which is more boitroidal. It was often assumed to be the same mineral and both were classed under the same name of calamine. In the second half of the 18th century it was discovered that there were two different minerals under the heading of calamine - a zinc carbonate and a zinc silicate, which often closely resembled each other.

The silicate is the more RARE of the two, and was named hemimorphite because of the hemimorph development of its crystals. This unusual form, which is typical of only a few minerals, means that the crystals are terminated by dissimilar faces. Some specimens show strong green fluorescence in shortwave ultraviolet light.

Dichroic glass is glass containing multiple micro-layers of metal oxides which give the glass dichroic optical properties. The invention of dichroic glass is attributed to NASA and its contractors, who developed it for use in dichroic filters for space masks. It is also used in glass filters for dental lighting.

Recently dichroic glass has become available to artists through dichroic coating manufacturers.

The main characteristic of dichroic glass is that it has a transmitted color and a completely different reflected color, as certain wavelengths of light either pass through or are reflected. This causes an array of color to be displayed. The colors shift depending on the angle of view, and the quality of the light.

Basically it reflects and refracts light transmitting the opposite colors of the spectrum at the same time.
