Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%Seen from above this is a plain solitaire. An emerald cut lab grown diamond, four claws, a smooth domed band with no stones on it at all. The detail is underneath, where a hidden halo of pave diamonds circles the base of the centre stone and the shank splits into two curved arms that meet like the petals of a tulip.
Hidden halos work because of contrast. Nothing distracts from the step cut when you look straight down at the ring, but from the side there is a bright line of small diamonds under the stone, and the centre appears to float above them. It also lifts the stone slightly, which suits an emerald cut because more of its depth stays visible.
The split tulip gallery is the structural part of the design. Instead of a solid box under the diamond, the band divides into two tapering arms that rise, curve inward and support the head from both sides. The result is open, light and considerably less heavy on the finger than a closed basket, and it lets light reach the pavilion from beneath.
The band itself is domed, rounded on both the outside and the inside, and completely plain. That is a comfortable shape to wear all day and the easiest kind of band to resize.
Made to order 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 or 18K white gold. Yellow gold, shown here, gives the strongest contrast between the warm plain band and the bright hidden halo. White gold and 925 sterling silver make the halo blend into the centre stone. Rose gold sits between the two.
Ring size is fully customisable. Choose your size at checkout or write to us with the size you need, including quarter sizes, half sizes and sizes outside the standard range. A plain domed band like this one is the simplest of all our designs to resize later. If you are unsure, we can help you measure at home.
Every ring is made to order. You can request a different centre carat weight, a different colour or clarity grade, a coloured centre stone such as emerald or sapphire, the hidden halo left out, pave added to the band, or an engraving inside the shank. Write to us at mapplegems.com/pages/contact and we will quote before making anything.
Is a lab grown diamond a real diamond?
Yes. It has the same carbon crystal structure, the same hardness of 10 on the Mohs scale and the same brilliance as a mined diamond. Only the origin differs.
Is a certificate included?
Yes. An IGI certificate for the centre stone is included at no extra cost and lists carat weight, colour, clarity, measurements and laboratory grown origin.
How is this different from your other hidden halo emerald cut rings?
Most of our hidden halo rings also carry pave along the band. This one keeps the band completely plain and adds a split tulip gallery, so the only diamonds besides the centre stone are the hidden halo itself. It is the quietest hidden halo design we make.
Can you see the hidden halo when the ring is worn?
Yes, from the side and at an angle. From directly above it is invisible, which is the whole intention. It is a detail for the wearer and for anyone who looks closely.
Will a wedding band sit flush against it?
Yes. The band is plain and the setting is lifted above it, so a straight wedding band sits neatly against this ring on both sides.
What does the split tulip gallery do?
It supports the head from two sides while leaving the space beneath the stone open. That reduces weight, lets light in from below, and makes the ring easier to clean than a closed basket.
Which carat weight suits this ring?
All four are made for it. With no stones on the band, the centre diamond is the entire design, so larger weights look especially striking here.
How do I clean it?
Warm water, a drop of mild dish soap and a soft brush, paying attention to the hidden halo where dust settles. The open gallery makes rinsing easy. Dry with a soft cloth.
How long does it take to make?
Each ring is made to order, so please allow our standard making time from the day your metal and size are confirmed. We will confirm the schedule when you order.
Lab grown diamonds have the same composition, hardness and optical behaviour as mined diamonds, at a fraction of the price. In a plain solitaire, where nothing distracts from the stone, that saving goes straight into carat weight and quality. Every centre stone we set is grown in a controlled laboratory and graded by IGI before it reaches our bench.
Mapple Gems is a jewellery workshop in Surat, India. A hidden halo has to be set on a curved surface that nobody sees straight on, and the split arms of a tulip gallery have to match each other exactly or the head sits crooked. Our setters do this work by hand every day. Because you order directly from the workshop, changes in carat weight, metal, stone colour or the halo itself are ordinary requests for us.
