I recently went mining in Nevada for turquoise (see some of my earlier posts) and found some great pieces. (I am part owner of a jewelry store and we own some turquoise mines). That made me very curious about turquoise, which is one of my favorite colors.
Today I listed a bracelet on ebay that is made of howlite turquoise. Since the bracelet was so beautiful, I was wondering what howlite turquoise was.
I found this great article to explain it… at wisegeek.org.
Here is the beginning of the article…
Howlite, scientifically called a calcium borosilicate hydroxide, is a silicate mineral often used to replicate turquoise. In nature, the stone is white or grey with dark stripes. Although the mineral is often legitimately sold, it is occasionally pawned by dealers as real turquoise, which raises the price considerably.
The mineral was discovered by and named for Henry How, a 19th century Canadian geologist. Initial deposits were found in How’s native Nova Scotia, but have since been uncovered in Southern California as well. The mineral is now generally mined for its use as an imitation stone, although some New Age practices use undyed stones for meditation.
The mineral has a porous structure that allows it to accept dyes uncommonly well. Because of the characteristic streaks found in turquoise, howlite makes an excellent substitute. The Mohs scale hardness of the mineral is only 3.5, considerably lower than the average turquoise hardness of 5 to 6. This rating means that the imitation is more likely to be scratched or fractured than the authentic stone.
Other than this difference, the two stones are nearly identical, and some claim that even jewelers have difficulty telling them apart in absence of ultra-violet (UV) testing. In UV tests, howlite often appears to give off colored fluorescent glows. It also dissolves quickly in hydrochloric acid without causing bubbling, something turquoise will not do.

Love that vintage tupperware! It really does last forever if you take care of it. Recently I found some pieces that were never used — never even opened up from the plastic bag they were ordered in! These can be valuable items to resell on eBay.
Here’s a serve it all set and a pie taker. The receipts are still in the bag, dated 1987. I will be listing these soon on eBay. I have others listed right now.
vintage tupperware 4 ramekins
Like these 4 ramekins with lids — never used.
vintage tupperware servalier bowls
And these servalier bowls. Remember the harvest colors from the 1970′s?
I just listed these square plates and mugs yesterday and the auction is already past 20.00. These are not new but are in very good condition with a few scratches and 3 of them have stains.
Here’s a sample of some recent ended auctions:
set of 6 pastel tumblers, never opened 181.50
5 qt deep roaster ovenware new but vintage 152.50
6 pastel tumblers with lids, lightly used 119.99
10 servalier bowls with lids 117.50 (like the ones shown above)
vintage tupperware pickle keeper
So check your cupboards and your neighbor’s cupboards and your yard sales! Not everything is super valuable, but the better the condition, the better the value. I just listed this pickle keeper at fixed price for 9.99 in my eBay store. It won’t last long at that price! It has some scratches on the outside but the inside is like new! See it at everythingvintagesteph.com. and thanks for stopping by!
