Rz® simulated-diamond jewellery

Rz® is Roselle's diamond-simulant product line. An Rz® stone is not a diamond and is not a lab-grown diamond. It is offered for customers seeking a diamond-like jewellery appearance at a lower purchase price.

Know what you are choosing

Roselle sells separate product categories. Lab-grown diamonds and natural diamonds are diamonds; Rz® is a simulant. A simulant has a different composition and does not receive a diamond grading report. Always check the product description and stone type before ordering.

Rz® or lab-grown diamond?

• Lab-grown diamond: choose this for a real diamond, diamond specifications and an independent report for eligible stones.
• Rz® simulant: choose this when a lower-price, diamond-like fashion appearance is the priority.

Prices, sizes and available settings vary by product. The product page and order confirmation are the authoritative descriptions of the item being purchased.
