Because July’s birthstones are a motley crew (see the end of this post), I’m picking out just one of them to feature, since there’s so much to know about turquoise!
Turquoise is the modern, more often seen replacement for the traditional July “Foundation stone”, sardonyx. I’d like to start out by showing you some of the affordable genuine turquoise beads that are available. (I’ll try to show similar-sized beads to make comparison easier.)
For even greater economy, and a wider color range to work with, try some other stones that are called turquoise.
Finally, consider some other stones in the turquoise family (which you can read about in our Gemstone Beads Index). There’s apple-green turquoise and lime turquoise, for example. You can often find specially purchased, special-priced strands of these and similar stones at Rings & Things’ BeadTour bead shows…another great reason to attend when we’re in your town!
Other July birthstones run the gamut: ruby (also Summer’s birthstone), synthetic corundum, emerald (for Cancer), onyx (for Leo), and topaz (St. Matthew’s stone).Thanks once again to Bruce G. Knuths’ “Jeweler’s Resource” book for all of this information!

I’ve recently discovered Yellow Turquoise and have been really enjoying getting creative with it!
Nice to have alternatives to just rubies for July birthstones!
I had no idea that turquoise was also my birthstone (July 23rd). I have quite a bit of it, maybe I had a subconscious draw to it all along!
What list are you looking at for Turquoise being a brithstone for September?
Most lists say turquoise, blue zircon and tanzanite are December birthstones while alexandrite, moonstone and pearl are for June birthdays.
Of course, the lists of stones for each month changes over time as the jewelers promoting such lists want to promote different stone. Google or wikipedia seach for “birthstone” will give you more common lists. Check it out!
Bruce Knuth’s book has turquoise as the alternative “Foundation Stone” birthstone for July. It’s definitely true that a gemstone sometimes shows up in various months of the year, depending on whose birthstone list you’re following. Knuth points out (page 10),
“After various lists had been devised by [various jewelers' associations], a list was devised by the Jewelry Industry Council in 1952. This list was eventually adopted by [those groups].”
I’m sure another factor is how old a birthstone list is. The stones known in Biblical times were a different bunch from what modern jewelers often work with!
