Its minimalist structure allows the brilliance and symmetry of the princess-cut stone to stand out, making it a popular choice for customers seeking a modern engagement ring with classic elegance.

The model is engineered for professional jewellery manufacturing, offering smooth surfaces and accurate stone seats optimized for casting, polishing, and stone setting processes. The structure also allows efficient finishing while maintaining durability and aesthetic appeal.
