I lost an identical charm and decided to order a replacement from a different company because of the price. It came in a super cute box. My daughter is studying to be an engineer and the little angle with wings made of formulas was a bonus. I see they have all sorts of STEM inspired jewelry! Only thing I would change is shipping method/speed.
I purchased a pendant necklace recently. I am absolutely charmed with it - the quality is top-notch and it looks beautiful. The necklace was delivered in a very timely fashion (especially given today's problems), in a sweet box that I will re-use at some point. I couldn't be happier with the value of my purchase.
