I can't tell for sure because the engraving is too small, but I believe it's from 4°C. It's from about 20 years ago, and I think it's cute because the prongs holding the zirconia are heart-shaped and the design is elaborate. I remember it was originally a cell phone strap. There are some areas where the crystal part is a little cloudy. Please check the images.
