Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%An oval cut lab grown diamond in four claws with a round brilliant diamond claw set on each side, on a plain band whose two ends cross beneath the head before running away round the finger.
Round side stones are the oldest and least fussy way to build a three stone ring, and they suit an oval better than most people expect. The usual objection is that a circle beside an ellipse creates two competing outlines. In practice it does the opposite when the proportions are right, because the round repeats the curve of the oval at its widest point and simply stops sooner. Read across the finger you get a small circle, a long ellipse, a small circle, which is a rhythm rather than a clash. It also means all three stones are brilliant cuts, so they behave identically in light. Where a step cut side stone sits quiet beside a lively centre, three brilliants flash together and the whole head reads as one bright object. That is the correct choice for someone who wants maximum sparkle rather than architectural contrast. Beneath the stones the shank crosses over itself in a shallow twist before separating into the band, which lifts the head slightly clear of the finger and opens a small space that a wedding ring can tuck into. Nothing else is decorated. The band is round in section, polished bright and carries no pave.
The shank is round in section and polished bright. Beneath the head its two ends cross over one another in a shallow twist before running away round the finger. The interior is comfort rounded.
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.
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.
We can change the carat weight, enlarge or reduce the round sides, substitute pears or emerald cuts, add a hidden halo, or set pave along the shank. 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 has the same carbon crystal structure, the same hardness of 10 on the Mohs scale and the same optical behaviour as a mined diamond, and it is graded on the same scales by the same laboratories.
Does the ring come with a certificate
Yes. An IGI certificate for the center stone is included at no extra charge.
Do round side stones work beside an oval
Yes, when the proportions are right. The round repeats the curve of the oval at its widest point and stops sooner, so the three stones read as a rhythm rather than as competing shapes.
How is this different from pear or baguette sides
All three stones here are brilliant cuts, so they flash identically and the head reads as one bright object. Pear sides stretch the design along the finger, and step cut sides sit quiet against a lively centre.
What do the three stones represent
The usual reading is past, present and future, which is why the three stone ring is chosen as often for an anniversary or an upgrade as for a proposal.
Why does the shank cross beneath the head
It lifts the setting slightly clear of the finger and opens a small space that a wedding band can tuck into without touching the claws.
Does this ring sit flush with a wedding band
Closer than with a straight shank, because the crossover leaves an open space beneath the head.
How long does the ring take to make
Three stones matched for colour and set level with one another, so allow sixteen to twenty working days before dispatch.
Three brilliant cuts sitting side by side are compared directly, so a side stone even slightly warmer than the centre is obvious at a glance. Lab grown material lets us cut all three to one grade from the same run, with a traceable origin and no mining.
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.
