RING DETAILS

Each Henry Francis ring is made after your diamond has been sourced, so the setting can be created around the exact dimensions of your chosen stone.

This allows the prongs, basket, gallery, and overall proportions to be made specifically for that diamond, rather than forcing the stone into a generic setting.

Setting

Average Band Width

2mm
Stone

Lab Grown Diamond

Every Henry Francis ring is made with a carefully selected lab-grown diamond.

-D–F colour target
-VVS2+ clarity target
-Excellent or ideal cut where applicable
-IGI or GIA certification
-Visual screening for proportion, spread, symmetry, and overall appearance

For fancy shapes such as oval, pear, marquise, radiant, emerald, cushion, asscher, and princess, we also assess visual factors such as:

Bow-tie effect
Windowing
Length-to-width ratio
Face-up size
Facet pattern
Overall balance

We do not choose diamonds by certificate alone.

Each ring is made to order and dispatched after final quality checks.

Estimated dispatch time: 3-4 weeks

Shipping times vary by destination and will be calculated at checkout where available.

International orders may be subject to duties, taxes, or import fees depending on your country.

If you need your ring for a proposal date, please contact us before ordering.

The Henry Francis Ring Try-On Kit lets you compare 10 shapes on your own hand before your final ring is made.

If you purchase an eligible try-on kit, the kit price can be credited toward your final engagement ring.

This helps you choose with more confidence and less pressure.

Because engagement rings are made to order, changes or cancellations may not be possible once diamond sourcing or production has begun.

Please check your selected shape, size, metal, carat, and ring size carefully before ordering.
