Ingredients
7-carat lab-grown marquise diamond, E colour, VS1 clarity — solitaire-set on a hand-forged 18-karat gold band. Worn close to skin, alive on the hand.
The marquise cut traces back to a 1745 commission from Louis XV — a stone shaped to mirror a particular smile. Two and a half centuries of jewelry tradition turned that geometry into an engagement-ring cliché. The Marquise Ring takes the cut back: not for a proposal, not for a vow, but as a daily mark of a self-defined choice. A single 7-carat lab-grown marquise diamond — E colour, VS1 clarity — solitaire-set in hand-forged 18K gold, low enough to clear a sleeve. Worn on whichever finger you prefer; there are no rules embedded in this piece. The shoulders of the band are kept clean so the stone reads as a line rather than as a centerpiece. Real lab-grown carbon, graded 10 on Mohs, same brilliance as a mined stone at a fraction of the extraction cost. For people who picked the cut and refuse the meaning that came with it.
* A signal you carry on the finger.

Customer Info · The Fine Print
Each INVOID piece is hand-forged after you order. Below is exactly what that means for shipping, warranty, returns, and care — written in plain language with no surprises.
Shipping
Every piece is fabricated after your order is placed — there is no inventory shelf. Fabrication takes about 2 weeks, then 3 to 10 business days transit from Singapore depending on destination. You receive a tracking number by email when your piece leaves the studio.
Returns & Exchanges
Each INVOID piece is made to order with lab-grown stones cut to your spec. We still hold a seven-day return window for change of mind: an unworn piece in its original packaging may be returned within seven days of delivery. Outbound shipping is on the studio; return shipping is on the customer. The two exceptions below — defects and sizing — remain fully covered without restocking fees.
Warranty
INVOID guarantees the integrity of every solder joint, prong setting, bezel, and clasp for the lifetime of the piece, under normal daily wear. If something we built fails — a prong loosens, a bail snaps, a clasp gives way — we fix it. Email the studio with your order ID and photos; we respond within 5 business days.
Care
Lab-grown diamonds and sapphires are graded 9–10 on the Mohs hardness scale and tolerate daily life. The metalwork and the jade are softer. The rules below keep every piece looking the way it left the studio.
Support
INVOID does not have a call centre. Every inquiry is answered by the studio team that built your piece. Typical response: within 24 hours on weekdays (Singapore time).
