Frequently asked questions

What is an old mine cut diamond?

It is the antique cushion shaped cut of the 1700s and 1800s, hand cut with a small table, high crown and chunky facets that glow softly like candlelight. This ring recreates it in a lab grown stone with modern precision.

What is a signet style engagement ring?

It borrows the signet's low, solid gold profile and sets the three old mine cushions flush within it, bezel protected. The result is heirloom weight with everyday toughness.

Is this old mine three stone ring certified?

Yes, it comes with IGI certification, and the three stone layout carries the classic past, present and future meaning.

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
