How to choose

Choosing your round ring

Why choose a round diamond?

It returns the most sparkle of any shape and never goes out of style. If you want a ring she will love in thirty years, round is the safe, beautiful choice.

Which setting suits a round diamond?

A solitaire shows the diamond at its purest. A hidden halo adds sparkle from the side. A halo makes it look larger from the top.

Setting	Effect
Solitaire	Pure, classic
Hidden halo	Sparkle from the side
Halo	Larger look from the top

Four prongs or six?

Four prongs show more of the diamond. Six prongs keep the outline round and hold the stone a little more securely.

Questions

Round ring questions

Still deciding? A diamond specialist can walk you through options by video or phone.

Is a lab-grown round diamond a real diamond?

Yes. A lab-grown diamond has the same physical, chemical and optical properties as a mined diamond. Only its origin differs.

Does a round diamond look smaller than an oval of the same carat?

Yes, slightly. Elongated shapes spread their weight over a longer outline, so they read larger from the top.

Is round the best shape for sparkle?

Yes. The round brilliant cut is designed for maximum light return.

How long does a made-to-order ring take?

We make each ring to order in 2–3 weeks. It then ships free and fully insured by DHL or FedEx, arriving in 2–5 business days with a signature required.

Can I return it?

Yes, within 30 days of delivery if unworn. We send a prepaid, insured return label. Custom-designed, engraved and resized pieces are final unless defective.
