A striking round brilliant diamond gives this platinum solitaire its timeless presence. At 2.05ct, the lab-grown centre stone offers a generous focal point, while the classic six-prong silhouette keeps the design balanced and elegant. The cool white finish of PT950 platinum complements the diamond, creating a ring that feels as enduring as the promise it represents.
Individually certified by IGI, the diamond combines E colour, VS1 clarity and Ideal cut, with Excellent polish and symmetry. Its clean solitaire styling is beautiful worn on its own and pairs naturally with a wedding band. Whether chosen for a proposal, an anniversary or a personal milestone, this is a piece to make part of your story.

Fine jewellery is built to last, but a little care goes a long way — especially for pieces you wear daily. Here’s how to look after your Oscar & Co pieces by material.
Caring for your diamond
Lab-grown diamonds are exceptionally hard and won’t scratch under normal wear, but they can still attract oil and dust that dull their sparkle. Clean gently every few weeks with warm water, a drop of mild dish soap, and a soft-bristled brush (an old toothbrush works well), then rinse and pat dry with a lint-free cloth.
Caring for gold
Gold is a soft precious metal, so it’s the most prone to fine surface scratching over time — that’s normal and part of how gold ages, not a fault. Avoid contact with chlorine, perfume, and household cleaning products, which can affect the finish, and remove gold jewellery before swimming, showering, or exercising.
Caring for platinum
Platinum is dense and highly durable, and it doesn’t lose metal the way gold does when scratched — instead it develops a soft patina over time, which many people love. If you prefer a brighter, polished look, a jeweller can re-polish platinum back to its original shine.
Caring for silver
Silver naturally tarnishes with air exposure, especially if it’s not worn regularly. Store silver pieces in an airtight bag or pouch when not in use, and polish occasionally with a dedicated silver polishing cloth to keep it bright.
General care habits
- Put jewellery on last, after makeup, perfume, and hairspray
- Take it off before swimming, showering, exercising, or cleaning
- Store pieces separately — in a lined box or individual pouches — so they don’t scratch each other
- Have settings and clasps checked by a professional once a year
Annual inspections are recommended, not a condition of our warranty. Stop wearing your piece and contact us if a stone moves or a clasp becomes unreliable. Our lifetime workmanship warranty covers manufacturing defects; normal wear and routine maintenance are excluded. Your Australian Consumer Law rights are unaffected.

Lifetime workmanship warranty
Manufacturing defects are covered for as long as you own your piece.

Unrelated manufacturing defects remain covered. Annual inspections are recommended, not a condition of cover. Your Australian Consumer Law rights are unaffected.

30-day change-of-mind returns
We offer 30-day change-of-mind returns on eligible pieces, measured from delivery. The conditions below apply to change-of-mind returns only. They do not limit your rights for faulty or misdescribed goods under the Australian Consumer Law.
What qualifies for a change-of-mind return
- Item is unworn, unaltered, and in its original condition
- Item is returned in its original packaging, including any certification documents
- Return is initiated within 30 days of the delivery date
Please note: made-to-order pieces, resized rings, and engraved or personalised items are excluded from change-of-mind returns. Your rights under the Australian Consumer Law still apply, including if a fault develops after delivery.
How to start a return
Email customercare@oscarandco.com.au with your order number and the item you would like to return. We will provide return instructions. Customers pay return postage for change-of-mind returns; use a tracked service with suitable insurance for valuable jewellery.
If we confirm a fault or another issue covered by the Australian Consumer Law, we reimburse reasonable return postage costs. Keep your receipts and email them to us. See our warranty claim process for covered warranty claims.
Refunds
Once your return is received and inspected, we’ll process your refund to the original payment method. Refunds are typically processed within 5–7 business days of us receiving the item back.
Exchanges
Prefer a different size or design instead of a refund? Let us know when you start your return and we’ll arrange an exchange once your original item is received.
Faulty or incorrect items
If your piece is faulty, develops a fault or does not match its description, email customercare@oscarandco.com.au with your order details and the issue. We will assess it and provide the remedy you are entitled to under the Australian Consumer Law. The 30-day window, original-packaging conditions and change-of-mind exclusions do not limit these rights.
Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.
