Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%A round brilliant lab grown diamond raised on a hidden halo, set on a band deliberately kept narrow. This is a design that has to be looked at from the side to be understood. From above it appears to be a plain solitaire, nothing more, and the halo is invisible. Turn the hand and a full collar of small diamonds appears beneath the centre stone, wrapping the base of the setting in light. That is the whole appeal of a hidden halo. It is a private detail, seen properly by the wearer and by anyone close enough to look, rather than a decoration announced to a room. Keeping the band fine rather than pave set is what makes the effect work, because there is nothing else on the ring to distract from it. E colour, VVS2 clarity throughout, free IGI certificate for the centre stone. Made to order in Surat in ten metals and four carat weights.
Available in 925 sterling silver, 10K yellow gold, 10K rose gold, 10K white gold, 14K yellow gold, 14K rose gold, 14K white gold, 18K yellow gold, 18K rose gold and 18K white gold. On a fine band the metal is a thin line rather than a mass, so the colour reads as an outline around the stone. Yellow gold draws that outline warmly, white gold makes the band nearly disappear so the diamond seems to float. For daily wear 14K is harder than 18K, which matters on a narrow shank that carries all the structural load.
Every ring is made to your finger size, so choose your size at checkout. If you are unsure, measure the inside diameter of a ring you already wear or ask us for a free size guide before ordering.
We can widen the band, add pave along the shoulders, remove the hidden halo entirely, or raise the setting into a cathedral profile. For any other customization request please contact us at https://mapplegems.com/pages/contact and we will quote it before you order.
Will anyone actually see the hidden halo?
From directly above, no, which is the point. From any side angle it is clearly visible as a bright ring of small diamonds under the centre stone. The wearer sees it constantly.
Does a hidden halo make the ring look bigger?
Not in the way a visible halo does, because it does not widen the outline seen from above. What it does is lift the centre stone off the band, which lets more light travel underneath and makes the diamond look brighter and better presented.
Why keep the band plain rather than pave?
Because a pave band competes with the halo for attention. Leaving the shank fine and polished means the only decorative element on the ring is the halo, which is what gives the design its quietness.
Is a fine band strong enough for daily wear?
Yes, at the thicknesses we make. If you are particularly hard on jewellery we can add half a millimetre to the shank at no extra cost, which is invisible but noticeably more rigid. Just ask before ordering.
Is a lab grown diamond a real diamond?
Yes. Same carbon structure, hardness and brilliance as a mined diamond. Only the origin differs.
Do I get a certificate?
Yes. A free IGI certificate for the centre stone comes with every order, listing colour, clarity, cut grade and carat weight.
How long does it take to make?
Production usually takes ten to fourteen working days, plus shipping time to your address.
A lab grown diamond gives the same hardness, brilliance and fire as a mined stone at a fraction of the price, which is what makes a certified 4 or 5 carat round brilliant achievable. It is created without mining, so there is no excavation and no doubt about origin. Every centre stone we set is independently certified.
