What does AB mean?

The AB next to the rhinestone color stands for Aurora Borealis, named after the lovely  Northern Lights. Its beautiful array of ever-changing blues, greens, reds, and violets create a dazzling display on the horizon. The same shimmering rainbows of color can also be seen on stones with the AB coating. Its  appearance will change subtly depending on the surface  it sits on and the angle from which you see it.

Hotfix vs. Flatback Rhinestones

Hotfix Rhinestones - are ideally used for garments. They have a glue disk on the back of the rhinestone that when heat is applied the glue melts into the fibers of garments. We suggest applying your rhinestones at 325 for 15 seconds, cool peel and press again for 5-10 seconds.  The 2nd press sets the stones and helps remove any lifting that may happen when removing the sticky transfer tape. This will ensure your Be Createful rhinestones will adhere to your product for years to come. 

Flatback Rhinestones - are used for handplacing projects like tumblers, costumers, shoes and other items. Flatback rhinestones require an adhesive, like SuperTite, Liquid Fusion, or GemTec be applied so the stones will adhere to your finished product. Quality flatback rhinestones have a thin silver backing with the exception of transparent stones.  Transparent stones do not have a backing so the color below the stone can be seen.

*All stones are packaged by weight therefore the actual stone count can vary per bag. 

**AB and Metallic products have coatings applied over the product to achieve their unique color. Products with these coatings can show wear or chip over time with handing or use. 

***Rhinestones are created from color lots. Color lots are also used for products like material, yarn, tile, paint, and many other items. Slight differences in time, temperature, humidity, and other factors can result in different shades of the same color. We work closely with our manufacturer to keep our colors consistent, but there can be slight color differences as each batch of the same color is made.

****We do our best to provide images that represent the most accurate product colors. Due to screen variations for computer monitors, phones, and tablets, colors may appear different depending on the device you view the images on.  

****Our low-lead stones have been tested by the manufacturer and are found to meet federal requirements of containing less than 100ppm lead count. The PPM is based solely on the manufacturer’s testing and official test results can be provided per request. Be Createful has not tested the rhinestones. 

*****Small items such as rhinestones and pearls are a choking hazard to children and pets. Do not allow children or pets to play with rhinestones. Additionally, new “Lead Laws’ advise rhinestones may be unsafe for children 12 and under and should not be used to decorate garments.

Vibrant BLUE

If you a TRUE Blue then Cobalt is it! It vibrancy holds its own against dark backgrounds. In my opinion this is a beautiful color to represent Navy.

Different color

I love everything I had ordered from here except for the bulk Cobalt Blue glass. I started with individual packs of 1440 because I’m doing a big project, I ran out of the small packs so I ordered the bulk and I was really disappointed with the color quality. You can see the difference in colors on my tumblers 🥺 the bulk color is not as reach. Now I can’t give my customer two of the tumblers and she ordered 12 and they will be different colors 😒

This has become my favorite color stone it's so beautiful

Rich G.

First of all this cobalt blue is such a rich and vibrant blue color. The quality of the rhinestones and how much they reflect the light and sparkle is amazing. But more amazing than all of that is the level of support I received from BeCreateful and Annette when I set off on my ambitious project for a public art exhibit - having never done anything like this before! I can not thank you enough!

So lets see I purchase the product on Dec 4th and now Dec 13th still no product sat on hold for almost 2hrs with USPS to be told in route and to have Be Createful to tell me still in Distribution Center. Either way lot of hard earned money to still this day have it saying that it is "Ready to Ship" a Pre Shipment Info sent and they are awaiting the item. So that tells me they do not have the package yet but everyone says different either way, first time customer and last time customer. Lovely you ask me for a review and I do not even have my product maybe you should of turned off the auto review to customers if you know these are issues right now according to what you have now told me 2x that I have called your facility. So who knows when my product will ever come if ever at all. They have till the 21st and then Be Createful will be refunding me my money. Can only blame the USPS for so long. If you know it is an issue with them then use UPS or FedEx instead of losing customers.

Best rhinestone flock EVER

This is hands down the best rhinestone flock I’ve ever used. Easy to work with, easy to weed - others require hours of weeding, this is effortless and easy! Highly recommend. You won’t be disappointed.

Perfect for a sparkle

These strings are used by me to add a sparkle to a hooded shirt. I've used them in both child and adult hoodies. And yes they are longer than needed for a child but that's okay because they are for looks in my crafting. I also want to make a note that these do not tie well because again they are for looks. They are perfect for me.


I have tried so many different rhinestones and these are by far my favorite!


The color and shine on this is beautiful
