Frequently Asked Questions
What is a cushion cut diamond?

A cushion cut diamond ring blends soft, rounded corners with elegant edges for a timeless yet modern look. Known for its pillow-like shape and beautiful sparkle, cushion diamonds can be square or elongated. It’s a perfect choice for anyone seeking a romantic engagement ring with classic charm and modern brilliance.
Do you offer elongated cushion cut engagement rings?

Yes! You can find cushion cut engagement rings in both our In Stock and Made to Order collections. Our In Stock selection includes hand-selected center stones, with several beautiful elongated cushion cut options available. With our Made to Order collection, you can choose the diamond for your own elongated cushion cut engagement ring. For a more elongated look, select a cushion cut diamond with a length greater than its width. If you need help finding the ideal diamond or selecting the right elongated cushion cut, our customer care team is always happy to assist. 
Do you have colored diamond or sapphire cushion cut engagement rings?

Our in-stock collection of engagement rings occasionally features beautiful cushion cut designs showcasing colored diamonds and sapphires. Since many of these gemstones are one-of-a-kind, availability is limited, and each unique cushion cut engagement ring is only offered until it finds its new home. Cushion cuts are especially popular for colored diamonds and sapphires, so our collection may include both classic and elongated cushion cut styles. If you’re looking for a distinctive colored cushion cut engagement ring, keep an eye on our latest arrivals and sign up for our email updates to be notified when new one-of-a-kind designs become available.
Do you have a cushion cut diamond ring with a lab grown diamond?

With our made-to-order cushion cut engagement rings, you have the flexibility to choose the diamond that best suits your style and preferences. You can select either a lab-grown diamond or a natural diamond for your ring. We also occasionally feature lab-grown diamonds in cushion cut designs from our in-stock collection. Since these in-stock pieces are available in limited quantities, they can only be purchased while supplies last.
How do I choose a wedding band for a cushion cut engagement ring?

When choosing a wedding band for your cushion cut diamond engagement ring, consider the overall style and look you want for your wedding ring set. Both straight and curved bands can beautifully complement a cushion cut center stone. However, if you have an elongated cushion cut engagement ring, a straight band may leave a small gap between the two rings. A delicate diamond wedding band offers a classic and timeless look, while a wider, chunkier band creates a more modern and distinctive style. If you prefer a thicker band, consider a custom wedding band designed specifically to complement your cushion cut engagement ring. Details such as a gentle taper or curved cutout can help the band fit neatly around the center stone, creating a comfortable and cohesive wedding set.
