Ingredients
Hand-forged 18-karat gold cuff, set with seven 0.70-carat lab-grown sapphires in royal blue — 4.90 carats total, eye-clean, bezel-set. A deep-blue refusal of permission.
Royal blue sapphire is the rarest of the corundum family — when mined, it is the colour collectors fight over and the colour that rarely makes it into casual jewelry because each stone is too valuable to set freely. Lab-grown changes that math entirely. The Sapphire Cuff carries seven 0.70-carat lab-grown royal blue sapphires across the wrist, bezel-set in hand-forged 18K gold — 4.90 total carats of saturated blue you can wear to the grocery store. Same chemistry as a mined stone, same Mohs hardness of 9, same fire. None of the geopolitics behind it. Open-back cuff so it slides on without a clasp; sized once, worn always. The seven stones are matched for saturation so the line of blue reads continuous across the wrist — no one stone steals the read, nothing drops out under shadow.
* Same fire as the earth, none of the scars.

Everything You Should Know Before Wearing INVOID
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
Made to order. Hand-forged in Singapore.
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.
- Singapore — flat SGD 10
- International (27 countries: US · CA · UK · EU · AU · NZ · JP · KR · HK · AE · IL · MY) — flat SGD 30
- Orders ≥ SGD 135 — shipping is on the studio, worldwide
- Countries outside that list: email the studio to arrange shipping
Returns & Exchanges
Seven days to change your mind. Return shipping is on you.
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.
- Change of mind — request a return within 7 days of delivery. Piece must be unworn and in original packaging. You cover return shipping; we refund to the original payment method once the piece is back at the studio.
- Defects or shipping damage — report within 14 days of delivery with photos. Studio repairs, replaces, or refunds; we pay return shipping both ways.
- Ring sizing (sgn-03 · sgn-04) — request a resize within 14 days. You cover round-trip shipping plus a SGD 50 craft fee. Once per piece.
- Pieces that have been altered by another jeweller, lost their original packaging, or arrive past the stated window are excluded.
Warranty
Lifetime structural warranty on every piece.
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.
- Covered — solder failures, loose prongs/bezels, clasp/bail breakage on undamaged pieces, original-stone replacement if a stone drops within 30 days of delivery
- Not covered — physical damage (impact, crushing, chemical exposure, chlorinated water, bleach), natural patina on oxidised silver, modifications by another jeweller, normal cosmetic wear
- Stone loss reported more than 30 days after delivery is treated as wear-and-tear and is excluded — inspect your piece on arrival
Care
Wear it daily. Protect it deliberately.
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.
- Take it off before swimming, showering, sleeping, and any contact sport
- Avoid bleach, chlorinated pools, hot tubs, and salon chemicals — these dull gold and pit silver
- Clean at home with warm water, mild soap, and a soft cloth — no ultrasonic cleaners on the jade pendant
- Send any piece back to the studio for complimentary professional polishing once per year
Support
Talk to the studio directly.
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).
