Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%Seen from above this is a plain emerald cut solitaire on a very slim band. Turn the hand and a secret halo appears, a single line of micro pave moissanite wrapped around the base of the crown and visible only in profile. It is the same idea as a hidden halo but taken further, because the band here is deliberately thin and the head sits high, so the halo is fully exposed from the side instead of half buried in metal.
Thin bands make centre stones look bigger. That is the whole trick of this design. A one point six millimetre shank gives the eye almost no metal to measure the emerald cut against, and the high setting lifts the stone away from the finger so light passes underneath it. The secret halo then adds a bright line exactly where the stone meets the setting, which visually extends the outline of the emerald cut. The result is a ring that looks minimal in a photograph and much larger than its carat weight on the hand.
Four claw prongs hold the corners of the emerald cut in a raised open basket. A continuous row of micro pave moissanite runs around the underside of the crown on all four sides, forming the secret halo. The shank is smooth, round and slim, approximately one point six millimetres, with a comfortable polished interior. The higher profile leaves room for a wedding band to sit flush underneath.
Choose from recycled 925 sterling silver, or solid 10K, 14K and 18K gold in yellow, rose and white. Yellow gold, as photographed, sets up a strong contrast between warm metal and the white line of the secret halo. White gold and sterling silver merge the halo into the setting for a cleaner, icier effect. Rose gold sits between the two. White gold is rhodium finished.
Every ring is made to order in your size. Sizes run from 3 to 13, including half sizes. If you are unsure, pick the closest size to your usual fit and contact us, and we will confirm it before production starts.
A secret halo sits where hand cream collects, so clean the ring every few weeks with warm water, mild dish soap and a soft toothbrush, working the bristles under the crown from all four sides. Rinse and dry with a lint free cloth. Slim bands are more likely to bend than thick ones, so remove the ring before lifting weights or carrying heavy bags.
Is a thin band strong enough for a large stone? Yes, in solid gold at these widths. What thin bands do not tolerate well is repeated crushing force, which is why we recommend removing any slim ring for gym work or heavy lifting.
What is the difference between a secret halo and a hidden halo? They describe the same construction. Secret halo is usually used when the band is slim enough that the halo is fully visible in profile rather than tucked into the setting.
Will this stack with a wedding band? Yes. The raised head leaves clearance, so a straight band sits flush beneath the setting without touching the centre stone.
Which metal should I choose? For maximum whiteness choose white gold or sterling silver. For warmth and contrast choose yellow or rose gold. For daily wear over decades, 14K balances colour and durability best.
