Fluorescent Cabochons - cabs made from minerals that fluoresce in either short-wave (SW) or long-wave (LW) ultraviolet light. Some pieces are free-form and suitable for wire-wrap jewelry or simply for collecting; others (where indicated) are standard sizes for mounting in various jewelry findings.  To see the fluorescent colors, you need a special ultraviolet lamp. For most pieces you will need a Short-Wave (SW) unit, which puts out a wavelength of 254 nanometers. 

Item in picture is the same one that's for sale. Each cabochon or piece of jewelry is a unique item.  Stones are natural in origin;  in a few cases (where noted) stone may be treated with epoxy to fill small pits or strengthen it.  Normally, however, we prefer not to treat stones.

Bustamite & Willemite with Andradite, etc. - Franklin, NJ.  In SW only the willemite responds (bright green).  However, LW (350 nm) gives a pleasant surprise:  the bustamite glows  bubble-gum pink, with the willemite responding green.  The color combination is  reminiscent of watermelon. 

Photo shows piece in LW.  We do not have a daylight photo available.  The piece appears ivory- or marble-white in daylight, with dark honey-brown spots (andradite) and some black veining 

This is one of only 4 or 5 cabs that came from a single rock.  We haven't seen material quite like it before or since.

Large oval cabochon, max. dimensions 40 mm x 30 mm

#CT1106 ... $35.00

Willemite & Calcite  - Franklin, NJ.  Angular freeform.  This willemite is green in natural sunlight due to FL response caused by the sun's UV.  Perhaps not coincidentally, it is also FL in LW to a considerable extent, though it is brighter and more vivid in SW.

FL photo shows piece in SW.

Size: about 33 mm (widest) x about 40 mm (tallest)

#CT1112.... $18.00

Willemite & Calcite with Glaucochroite, etc.  - Franklin, NJ.  Freeform.  This is primarily a SW-piece, with willemite (green in SW) and calcite (red-orange in SW).

There are beautiful daylight colors in here as well, thanks to the willemite ("grape" red-purple) and rhodonite (pink).  The glaucochroite also appears either pale lilac-purple or blue-gray, depending on whether it's viewed under incandescent or white fluorescent light.

Size: about 20 mm wide x about 33 mm long.

#CT1092.....$20.00
