Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%An emerald cut lab grown diamond in a four claw head with a hidden halo beneath and pave running down both shoulders. The proportions here favour the stone above everything else. The emerald cut is set high enough that its full depth is visible from the side, the hidden halo sits tight under the girdle rather than spreading wide, and the shoulder pave is kept to a single narrow row so the band stays slim against a large rectangular head. The effect is a ring that looks almost entirely like diamond from above and reveals its construction only in profile. 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. Step cut stones show their body colour more openly than brilliants, so a white metal keeps the emerald reading icy while yellow and rose gold lend it warmth. Because the pave is a single narrow row, a warm metal keeps the band looking slim rather than busy. For daily wear 14K is harder than 18K and better protects the corners of a step cut stone.
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 remove the hidden halo, widen the pave to a double row, leave the shank plain, or set the emerald east to west across the finger. For any other customization request please contact us at https://mapplegems.com/pages/contact and we will quote it before you order.
What is a hidden halo?
A ring of small diamonds set around the base of the centre stone facing outward. From above you see only the emerald cut. From the side it shows as a bright collar underneath.
Why is the setting height relatively high?
An emerald cut has significant depth below the girdle. Setting it a little higher lets that depth be seen from the side and lets light travel through the pavilion rather than being blocked by the shank.
Why does an emerald cut sparkle less than a round?
It is cut with long parallel steps rather than many small facets, so it produces wide mirror like flashes instead of fine glitter. That open surface is also why clarity matters more, and why we set only VVS2 stones.
Does the carat option include the halo and pave?
No. The carat you choose is the weight of the emerald centre only. The hidden halo and pave are additional at every carat weight.
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 matters especially for an emerald cut. Its open table shows inclusions readily, so high clarity is essential, and VVS2 at 4 or 5 carat is only achievable at this price as a lab grown diamond. Every centre stone we set is independently certified.
