Description

The Lab Grown Three Stone Cushion Cut Engagement Ring features a cushion cut center stone complemented by round side stones for a balanced three-stone arrangement. A four-claw prong setting secures the center diamond while keeping its cushion shape clearly visible. This Cushion Three Stone ring with round side stone offers a distinctive alternative to a traditional solitaire for USA buyers seeking a structured lab grown diamond engagement ring. Antiquecut offers this design for shoppers comparing three stone solitaire rings with additional diamond detail.

The three-stone layout creates a wider presence across the finger while keeping the cushion cut as the main focal point. Round side stones add definition without distracting from the center diamond. Metal type, exact carat weights, diamond grades, and certification should be confirmed from the selected product specifications before purchase.

Frequently asked questions

How does a larger three stone cushion ring wear?

With centers from 3.0 to 5.0 carats plus scaled side stones, it wears as a full statement across the finger, softened by the cushion's pillowy outlines. Yellow gold warms the whole trio.

Why use four prongs on each cushion?

Cushions have no fragile corners, so four secure points per stone hold everything safely while keeping the faces open to light. Classic engineering for a classic layout.

What quality options does this cushion trio offer?

The IGI certified cushion comes in DE VVS or EF VS quality, with 3.5 carats photographed.

How long will my order take to arrive?

Each piece is made to order by our skilled craftsmen. Production typically takes 8 to 10 business days, followed by 9 to 10 business days for secure international shipping with full tracking. In most cases, you can expect your order to be delivered within 18 to 20 days from the date of purchase.

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are 100% real diamonds with the same physical, chemical and optical properties as mined diamonds. Every center stone we sell comes with an independent certificate.

Can I pay in installments?

Absolutely. We offer flexible payment options, allowing eligible customers to spread the cost of their purchase over time.

At checkout, you may be able to choose:

- Interest-free payments in 2 or 4 instalments

- Monthly financing from 3 to 12 months

- Additional extended financing options, where available
