U.P. Thomsonite Demystified

Demystifying U.P. Thomsonite: what is it? where is it found? how does it differ from "true thomsonite"?
Used in Beth's new dreamscape series as well as gemstone rings, U.P. Thomsonite has brought some unique color into our store!

"U.P. Thomsonite" is the close cousin of true thomsonite which is only found along the north shore of Lake Superior. U.P. thomsonite features very similar eye patterns and color bands to it's cousin from the north. Dark eyelets with feathery inclusions create unique patterns commonly sought out for use in jewelry.

U.P. Thomsonite features dark green eyes and variations of pink that are often pastel colors; rarely found in true thomsonite. The pink and green colors in U.P. Thomsonite is actually internal reflections from copper inclusions (additional minerals trapped within the gemstone).

 

 

U.P. Thomsonite is formed in a similar process as agates, trapped air pockets within volcanic basalt fill with prehnite (mineral base of U.P. Thomsonite) and microscopic bits of copper. Prehnite is usually pale green in color (Left picture below), but the copper rich area of Lake Superior has created Pink Prehnite (right picture below). The color intensity in the U.P. Thomsonite is due to the grain size of the copper inclusions within the gemstone.

U.P. Thomsonite is difficult to remove from the Balsalt matrix without breaking the gemstone, so most of the stones are from pebbles collected along the beaches. These stones were naturally removed from the basalt by being tumbled in Lake Superior.

Sizing
Ring Sizing

Purchase this ring sizer to help determine your ring size. This sizing tool is most accurate for double band rings and bands 6mm and under.

Fingers can change size due to many circumstances, the best way to get an accurate size is to check the size a couple of different times to determine your best size. The majority of our rings can be resized, but if the ring has a stone setting other than a diamond, it probably cannot be resized unless otherwise noted in the item listing.

Some of our rings with stones are shown with the stone not set in order for us to size the ring to your specifications and set the stone afterwards. This avoids damage to the stone during sizing. Reference the individual ring listings for more details. Wide Bands 7mm and above have more friction against the finger and will need to be ordered a little larger.

Our double band rings fit like a narrow band, when getting sized for a double band ring, you can get sized for a ring that is narrow.

When getting your finger sized, inform jeweler of the width band you are intending on purchasing and rely on them to determine your ring size.

Look here for more information about resizing items that you have already received.

Engagement Ring Sizing

Purchase this ring sizer to help determine your ring size. This sizing tool is most accurate for double band rings and bands 6mm and under.

There are many sneaky options for getting the size right, but the best way is to have their finger sized by a professional.

You may be able to sneak one of their rings and bring it into a jewelry store and ask to check the size.

Beth Millner Jewelry has wish lists too, so they could come in to the store and fill out a wish list and hopefully they provides their ring size.

Bracelet & Cuff Sizing

Measure wrist circumference. Take your measurement just above the wrist above bone.

Use the chart below to determine the correct size.

The bracelets we make are designed to fit comfortably, but if a looser fit is preferred, the next size up may be suitable.

X-Large 7-7.5 18-19

Bangle Sizing

Bangle Size is determined by hand size, rather than wrist size

Measure hand size by tucking your thumb in, just like when trying on a bangle. Measure around the thickest part of the hand while in this position.

Use the chart below to determine the correct bangle size.

Size Hand Measurement (inches) Hand Measurement (cm)
Small 7-8 18-20
Medium 8-9 20-23
Large 9-9.5 23-24
Pendant & Earring Sizing

When determining the size of pendant or earrings you would like to purchase, please reference the item description which includes the size of the piece.

Also, there will be an image with a hand in the picture to help visualize the size.

When choosing a piece for another person, we find that our customers choose pieces that are similar to their overall stature.

People that are shorter and small tend to like smaller items, tall slender people tend to like our longer larger pieces.

Chain Length

When picking out a chain, 18 inch is the most common length.

This would cause the pendant to sit between the collar bones.
