These 15mm cubic zirconia gems are the most beautiful gems Ive ever seen in my life. The quality is amazing and I love how fast they shipped. I was also very impressed at how it was delivered, each gem was separated on a soft white sort of material and then rolled tightly and snugly into a roll. No gems moved during delivery. That is what you call professional. Who needs diamonds when you can get these,which are better geologically anyway. Diamond is a 10 on the mohs scale so it's resistant to scratches but it has perfect cleavage so it can spilt if struck at the right angle with the right amount of force. CZ is 8, (still pretty hard though) but less resistant to scratches than diamonds. But it has no cleavage so it is actually more chemically stable, resilient and won't crack if it is struck. It's like leather VS glass. Glass is harder (just like diamond) but leather is tougher (just like CZ). I take the toughness over the hardness any day. Absolutely beautiful gems and if you have to wait for them, they are worth the wait. I love these so much I ordered 2 sets so now Ill have 10 gems! I don't use them for making Jewelry I just like to collect gems.

I ordered the 8mm round CZ's.I got them in 2 days and was very pleased with how beautiful, clear, and sparkly they are. I'm inexperienced in my new jewelry making hobby so I wasn't sure how big 8mm round diamond cut would be until actually seeing them. As it turns out they are a very decent size (about the size of a 2 carat real diamond) and a PERFECT and affordable substitute for real diamonds. Thanks to the tutorial by Jewelry Designer, Denise Mathew, I made some pendants by setting them in a wire wrapped bezel using copper and silver wire. I don't own the right size mandrel for making the bezel for 8mm so I have to improvise but the pendants turned out great anyway especially for my first time. These sparkly CZ's made all the difference. I will also be using them to attempt to make some solitary rings. I usually prefer silver jewelry; however, the copper wire bezels enhance the sparkle so much more than the silver wire. These CZ's are really beautiful. I'm so excited I bought them. I feel like I've graduated to a whole new level of jewelry making with these beauties. I can hardly wait to see which of my projects will use them. I'm looking forward to some jewelry making fun!Thanks for making these available to the public! 👠🙂

Aside from the immense sparkle and fire, which is what drew me to these CZs in the first place, I am so impressed with the way they were shipped it's like receiving a tray of diamonds! Each crystal was separated on a very soft multi layer paper then rolled into a tight well protected roll and boxed tightly...no stone was moved during shipping...quality beyond my wildest dream! I was not looking for a diamond look-alike, I just wanted the most fire and shine that I could get in a crystal, and this is it. These 5A CZs are better than any I have ever had. I will most definitely be ordering again, I feel that I have found a wonderful source for all my future CZs. Thanks to all for a quality product and fast and SAFE shipping.

Ha, no but these are so cool in that first off they were much cheaper than diamonds that in my opinion would struggle to look as brilliant. So the price for these is exceptional. They will work perfectly for my walking stick project.

These stones are so much better than I expected. Super brilliant and essentially flawless. The CZ quality is suburb. Also, the price is great.

It definitely has a lot of sparkle, but you wouldn't ever mistake it for a real diamond... even if you're 3 feet away and not an expert. Still giving it 4 stars. A lot of bling/sparkle for the price.
