3 Ct Cushion Cut Lab Grown Diamond Ring
We have created this cushion-cut diamond ring for jewelry lovers who adore rich and antique craftsmanship. The halo setting allows the stone to rest beautifully at the centre. This setting is stunning for those who want sleek craftsmanship while adoring the centerpiece.
This piece uses a 3 ct elongated cushion cut diamond, which gives the ring a slightly longer look without making it feel oversized or heavy. It keeps the classic shape but stretches it enough to make it look refined, clean, and very wearable.
What makes this design stand out is the hidden halo. It isn’t the kind of halo that you see from the top. Instead, it sits quietly under the center stone, adding a soft brightness when the ring moves.
The halo uses small round diamonds, and while it is subtle, it adds depth to the center stone without changing the minimal look of the ring. People notice it only when the ring tilts in the light, which makes the detail feel personal rather than attention-seeking.
Center Stone Features
-
3 ct elongated cushion-cut lab-grown diamond
-
E color, VS1 clarity
-
Balanced sparkle without harsh reflections
-
Elongated proportions that make the finger look slimmer
-
Lab-grown for transparent sourcing
The stone has a clean, bright appearance, but it doesn’t look artificially icy. The faceting gives a soft glow, which is exactly what people love about cushion cuts. Because the diamond is lab-grown, you get the same durability and structure as a mined diamond, but with full traceability.
Ring Specifications
-
Hidden halo with round brilliant diamonds totalling 0.08 ct
-
14K solid gold (Yellow, White, or Rose Gold options)
-
Approx. 1.5 mm band width
-
Smooth, polished band for everyday comfort

Setting height adjusted to avoid snagging
The band is intentionally simple. A diamond of this size already carries enough presence, so the rest of the ring stays clean and minimal.
Made In-House, Not Outsourced
Each ring is crafted at rustic and gold is crafted from start to finish.
Nothing is mass-produced, and nothing goes through unknown factories.
One jeweler works with the loose stone, builds the head, positions the hidden halo, and also sets each prong with precision. This slow, controlled process helps the ring look neat from all angles and sit comfortably on the finger.
Our team checks:
-
prong alignment
-
stone symmetry
-
polish and finish
-
hidden halo spacing
-
band balance
This reduces the bulky look many cushion-cut rings tend to have and keeps the design sleek.
Ethical and Responsible Materials
-
Lab-grown center diamond with documented origin
-
Recycled 14K gold
-
Ethically sourced natural accent stones
We use ethical materials because transparency matters. This is not “ethical” as a marketing word — it’s something we follow throughout the sourcing and production process.
Customization Options

You can adjust:
-
