Picture Frame Pendant

Sunday, April 11th, 2010

p4080175I have come to the realization that I have not talked about any of my new designs in quite a while. My latest picture frame pendant has become my recent favorite, and I think these will become a popular items this year.

My interest has not always been in jewelry making and the lapidary arts. I started out in visual arts, especially water color. When you paint a picture, it always looks better in a nicely matching frame, so I thought why not stones? This got me thinking of all my wife’s beads and especially beads made from Michigan rocks and minerals.  Between the rocky Great Lakes shorelines, stony gifts from the glaciers, and mineral finds in the Upper Peninsula, Michigan has a real variety of stone to choose from.  Many of our Michigan stones are miracles, found here and really nowhere else on earth.  What if I could frame these beads in a collage featuring a variety of the most popular of these Michigan stones, making a picture of Michigan Miracles, or Lake Superior Miracles?

I started playing around last year with sizes and designs for my window boxes and this winter decided that the most pleasing shape and size may be a rectangular box of around 20X30mm. Stones can be arranged in pleasing and artistic ways within these confines. Thicknesses of the frames can also be manipulated to protect the beads therein. I have made a couple of much larger frames also that some people enjoy. Larger, or more stones can be used in these larger frames.

The featured stone in a Michigan pendant could be expected to be our Michigan greenstone (chlorastrolite) which is found in small areas of the Keweenaw Peninsula or on Isle Royale.  We had some very nice Isle Royale Greenstone beads that were drilled incorrectly. These beads were drilled so when they are strung, you can only see the sides of the beads and not the widest and best part of the greenstone. By using a prong-set on these beads I was able to turn the best faces to the front of the pendants, giving folks a very large size greenstone for a reasonable price.  The cost of these gemstones alone is worth our low pendant price.p4080180

I think it is important that the best possible beads be used. If I’m going to make a little piece of art, I want to use the best media (stones), that are available.  I am selecting from a nice variety of Michigan miracles: greenstone, Petoskey stone, datolite, jasperlite, thomsonite, firebrick, kona dolomite, epidote, favosite, hematite, prehnite, copper/silver half breeds, and Lake Superior agate.

Wire wrappers should be warned that these pendants take me three times the time that I commonly spend on a pendant! I also think that it helps to have some training in balance, layout, and color and an artistic eye to make these little treasures.

We have posted a couple of these little Miracle treasures on out website, and hope you will experience the same enjoyment wearing and showing these pendants as I do making them.

Prehnite

Sunday, June 14th, 2009

Sometimes I find wonderful Prehnite on the mine dumps in the Keweenaw Peninsula.

If  prehnite forms in veins, as it does in the Keweenaw Peninsula, it generally associates itself with native copper. I love to find these rare pieces that make lovely jewelry, with the apple green of the prehnite surrounding the shiny copper.prehnite-with-copper1

Most of the Prehnite of the Keweenaw is vein Prehnite.  In vein Prehnite one cannot notice the chatoyant needle-like crystal structure normally associated with larger non-vein Prehnite pieces such as the gemmy pieces found in Australia and other locals around the world. Feather-like Prehnite crystals are seen in U. P. Thomsonite which is actually variegated and non-variegated Prehnite.   Pink, red, and green, and other color combinations can be found, depending on what minerals flowed into the vesicles and veins along with the Prehnite. Locals refer to pastel Prehnite permeated with copper flecks found on the beaches in the Calumet, and also in the Copper Harbor area as “Patricianite”. These Prehnite pebbles can be jewelry grade, and are wonderful to collect as they roll in with the Lake Superior breakers.

Prehnite is very solid, but brittle, so care must be taken when cutting it. Stay away from new grinding wheels and rough grits. Harmonic vibrations can blow apart this material.

High quality Prehnite is available from various locations throughout the world, but when you add the native copper to the Prehnite from the U.P., you can’t beat ours.
