Frequently asked questions

Why does the old mine cut glow instead of sparkle?

It was cut by hand centuries before electric light, with deep facets designed to smolder in candlelight rather than flash. This ring recreates that romantic glow in a lab grown cushion.

How does the split shank suit an old mine cushion?

The divided yellow gold band adds air and movement beneath the antique style center, keeping the heirloom look from feeling heavy. Old soul, light footprint.

Is this old mine ring certified?

Yes, the old mine cushion is IGI certified, made to order 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.

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

Your available plans will be displayed during checkout. Our payment partner determines eligibility, approval, and financing terms.
