ValueMAX Crystal is a budget alternative to brands such as SWAROVSKI and PRECIOSA crystal. These are superior to glass and acrylic. Scratches and chips are expected since they are not packed individually and factory does not sort the stones by quality. They are good for projects that require large quantity of stones without a high demand in quality, such as interior decor or temporary installation.
For better quality and slightly higher cost, you may consider
PREMIUM CRYSTAL.
