Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%A round brilliant lab grown diamond in four claws on a fine plain band. From above there is nothing but the stone and a thread of gold. Turn the ring and a short vertical line of tiny pave diamonds appears, running up the gallery post where the basket meets the shank.
This is what a hidden halo becomes when it is reduced to the smallest thing that still works. A full concealed halo wraps the entire outer wall of the basket and needs thirty or forty stones to do it. A pave set gallery post uses five or six, set in a single column on the one part of the setting that is genuinely visible from the side at conversational distance, and leaves the rest of the basket bare. The saving is not only cost. Every stone added to the outside of a basket has to be set into metal that must then be thick enough to hold it, so a full halo forces the whole head to grow. Confining the pave to the post keeps the basket as slender as an unset one, so the ring stays low, the stone stays close to the finger, and the detail is there for anyone who looks from the side without announcing itself from above.
The shank is a fine polished wire left entirely plain, running into the base of the gallery post without shoulders. Because the head carries almost no extra metal, the ring sits low and a wedding band meets it without a gap.
Choose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Every metal is fully hallmarked. Yellow gold is shown in the photographs, where the warm post frames the small column of white stones and makes it read clearly at the side view.
The ring is made to your finger size. Select your size at checkout. If you are unsure, we will send you a printable size guide before we begin work, and we adjust the shank thickness so the proportions hold at any size in our range.
We can change the carat weight, the centre stone shape, extend the pave into a full concealed halo or remove it entirely. Write to us through https://mapplegems.com/pages/contact and our workshop will prepare a quotation and a rendering before any metal is cut.
Is a lab grown diamond a real diamond
Yes. It is carbon in the same crystal structure as a mined diamond, with the same hardness and the same optical properties, graded on the same scales.
Does the ring come with a certificate
Yes. An IGI certificate for the center stone is included at no extra charge.
What is a gallery post
The short vertical bar of metal that joins the basket holding the stone to the shank. It is the part of a setting most visible from the side and least visible from above.
Why not set a full hidden halo
A full halo needs a thicker basket to carry the extra stones, which raises the whole ring. Setting only the post keeps the head slender and the stone low on the finger.
Why is the round brilliant graded differently to other shapes
It is the only cut for which the major laboratories issue a full cut grade, because its symmetry can be measured against an agreed ideal.
Can this ring be resized
Yes, easily. The shank carries no stones, so resizing is done entirely in plain metal.
How long does the ring take to make
Each ring is made to order. Production usually takes ten to fourteen working days before dispatch.
A lab grown diamond gives you a larger stone and a higher colour and clarity grade for the same budget, with a traceable origin and no mining. On a design this restrained, almost the entire value of the ring sits in the centre stone, which is where the grade shows.
Mapple Gems is a jewellery workshop in Surat, India, the city where a large share of the world's diamonds are cut and polished. We grow, cut, grade and set in one place, which is why we can offer certified stones in fully hallmarked gold at workshop prices.
