Two stones. A lifetime of meaning.

Customers typically buy between 0.10ct and 2.00ct each ear — the right size depends on what you'll wear them for. Our master jewellers' guide:

• 0.10–0.20ct each — The whisper. Barely-there sparkle for first studs, second piercings, or layered looks.
• 0.25–0.35ct each — Subtle elegance. Perfect for graduations, first-time gifts, and delicate everyday wear.
• 0.50ct each — Our top-selling size. Visible without being showy. Ideal for everyday wear and milestone gifts.
• 0.75–1.00ct each — Classic statement. Catches the light from across a room. The traditional anniversary upgrade.
• 1.50–2.00ct each — Heirloom-scale. For 25th anniversaries, 60th birthdays, and pieces meant to be passed down.

Looking for something even larger? Our master jewellers will design bespoke studs above 2.00ct on commission — book a consultation to discuss.

Still unsure? Use the ear visualiser above to see exactly how each size sits.

Identical to the eye, the microscope, and the lab. Both are real diamonds — pure carbon crystals with the same brilliance, fire, hardness (10 on the Mohs scale), and certification standards.

The difference is origin:

• Natural diamonds formed billions of years ago, deep in the earth, and were mined. GIA certified. They hold long-term value as collectibles and heirlooms.
• Lab grown diamonds are grown in controlled high-pressure / high-temperature chambers that replicate the earth's process — in weeks rather than aeons. IGI certified. They cost 30–60% less for the same size and quality, leaving room for a larger stone or a finer setting.

Both come with our lifetime warranty. Use the toggle at the top of this page to compare prices side by side.

The closure holds the stud in place. Three options, each with a purpose:

• Push-back — The traditional friction-back. Quick to put on, slim profile, ideal for everyday wear.
• Screw-back — Threads onto the post. The most secure option. We recommend it for stones above 1.00ct, frequent travellers, and active wearers.
• Lever-back — A hinged closure with a small lever. Comfortable for sensitive ears and impossible to lose — but adds a small visual element behind the stud.

All closures come standard in the same metal as your setting. We can swap closures any time at any of our studios — free of charge for the life of the piece.

Diamond studs are designed to be worn — every day, in the shower, while you sleep. To keep them performing their best:

• Warm soapy water and a soft toothbrush, once a week. Pat dry with a microfibre cloth.
• Remove before applying perfume, hairspray, or self-tanner — these can dull the surface.
• Bring them in once a year for a free professional clean and a 14-point security check at any Monroe Yorke studio.
• Avoid harsh chemicals like chlorine over time — it weakens the prongs on yellow and rose gold.

Every diamond above 0.25ct ships with a full grading certificate. Natural diamonds are graded by the Gemological Institute of America (GIA), lab grown by the International Gemological Institute (IGI). Both certificates detail the 4 Cs (cut, colour, clarity, carat) plus measurements and proportions — your diamond's unique fingerprint.

The certificate is yours to keep. For diamonds under 0.25ct, we provide a Monroe Yorke Diamonds certificate of authenticity prepared by our in-house master jeweller.

Every Monroe Yorke piece is covered for life against manufacturing defects, prong wear, and post breakage. The warranty includes:

• Free professional cleaning and polishing, any time.
• Free re-tipping of prongs as they wear with daily life.
• Free post replacement if it bends or breaks.
• Free upgrades — bring an older stud back and we'll credit its full retail value toward an upgrade.

The warranty is non-transferable but covers the original purchaser for the life of the piece. Insurance against loss or theft is recommended separately — we partner with Q Report for diamond-specific cover, full appraisal documentation included.

Shipping — Free insured shipping Australia-wide, dispatched within 10 business days of order confirmation. International shipping available on request — fully insured, signature required.
