JIANGYUANGEMS 12pcs 4mm Birthday Stone 1pcs Per Colors Round Loose Cubic Zirconia Stones Synthetic Ruby 5# Synthetic Spinel 113# (4mm)

Ive fired 2 of these in metal clay so far at 1675 F and they did fine. Im very pleased, especially considering the price!

CZs vary in brilliance. If you are looking for brilliance these are not the best. I purchase 7mm for using with copper metal clay. I torch fired them and they worked PERFECTLY! Cooled them in fire blanket. No cracking or chipping. For this need, I will buy them again and again.

They were exactly what I had been looking for!! Great quality !!

Very pretty;

Excellent sparkle. Well packed parcel. Im very happy with my purchase.

I used these to give as gifts to my students. They loved them because they are so colorful!

There was no March birthstone

IM so pleased with this purchase. I bought a ring with 3 interchangeable stones but wanted more colors and these did the trick
