Frequently asked questions

What are double prongs on a diamond ring?

Each corner of the blue cushion is held by a pair of slim prongs instead of one, a vintage detail that adds security and a fine jewelry finish. They frame the stone like tiny claws of light.

Why choose platinum for a fancy blue diamond?

Platinum is naturally white and never needs replating, so the cool metal keeps the blue reading true for decades. Its density also makes it the most secure home for a 4.0 or 5.0 carat center.

Is this blue cushion ring certified?

Yes, the fancy blue cushion is IGI certified, with the 5.0 carat version photographed in 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.
