About this design
Sapphires offer timeless elegance and symbolise loyalty and truth. They rival diamonds in durability (hardness 9/10) and come in stunning shades of blue. Many famous royals, including Kate Middleton, have worn iconic sapphire rings.
Natural sapphires form over millions of years in the earth, while lab-created sapphires are grown in a controlled environment. Both are chemically and optically identical; the difference is origin and typically price.
A hidden halo is a band of delicate diamonds nestled beneath the sapphire against the shank. It creates an optical glow and added sparkle without distracting from the sapphire's rich colour.
This ring is made to order and typically arrives within 8–10 days of purchase. Every order ships with free insured worldwide delivery and 14-day returns.
Yes — it is covered by our limited lifetime warranty, which includes free professional cleaning and prong tightening for life, plus one free resize within the first year.

Certified standards
Every diamond selected for our custom rings meets strict expert specifications. Here is how we grade each characteristic.
The cut determines a diamond's brilliance, fire, and scintillation. It is the most critical factor of the 4Cs.
We craft our rings exclusively with Excellent to Ideal Cut stones. This ensures maximum light refraction, giving the center diamond its characteristic intense sparkle that reflects from across a room.
Color refers to the presence or absence of trace tint within the diamond, graded from D (colorless) to Z (light yellow).
Our lab-grown diamonds are graded in the elite D, E, and F colorless range. To the naked eye, these stones are completely ice-white, ensuring that your ring reflects pure light without any distracting warm or yellow hues.
Clarity measures the purity of the diamond, observing microscopic inclusions inside the stone or blemishes on the surface.
We offer VS1 to VS2 (Very Slightly Included) diamonds. These stones are guaranteed to be 100% "eye-clean" — meaning any minor microscopic inclusions are completely invisible to the naked eye under normal viewing conditions.
Carat measures the physical weight of the diamond. 1.0 carat is equivalent to 200 milligrams.
We configuration-scale our rings to maintain perfect design proportions across all carat sizes (from 1.0 ct up to 8.0 ct). As the center stone increases, the accent diamonds in the hidden halo are adjusted in scale to keep the ring looking balanced.
Independent Grading
Certification is included only when a natural or lab-grown diamond centre stone over 0.7 ct is selected. Report details are specific to the selected diamond.
