Frequently asked questions

What is an antique green diamond shade?

It is a muted, storied green with an old world softness, closer to heirloom glass than neon. Paired with marquise side stones it feels like a ring with a past, built new.

Why do marquise leaves suit a green center?

The leaf shaped side stones turn the green round center into the heart of a tiny garden. It is nature inspired design told entirely in diamonds.

What sizes does this antique green ring offer?

The IGI certified green round comes in 2.0 or 3.0 carats, with 3.0 photographed, in 10k, 14k or 18k gold or platinum.

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.
