How to Clean a Diamond Ring

A diamond ring is more than just jewellery—it’s a symbol of love, worn every day.
Naturally, a little care goes a long way in keeping it luminous.

Best Way to Clean a Diamond Ring at Home
1. To clean your diamond ring at home, fill a bowl with warm water and a drop of mild, non-moisturising dish soap.
2. Soak the ring for 15 to 20 minutes to loosen any residue.
3. Then, use a soft-bristled toothbrush to gently clean around thediamond setting, including the underside where buildup tends to gather.
4. Rinse thoroughly with clean water and dry with a lint-free cloth. Avoid ultrasonic machines at home and steer clear of abrasive cleaners or chemicals—particularly if your ring features pavé diamonds, delicate craftsmanship, or coloured gemstones.

How to Clean Gold Jewellery

Gold is timeless—but like all precious metals, it benefits from a little care to maintain its natural lustre.
Whether it's yellow gold, white gold, or rose gold, regular gentle cleaning keeps your gold jewellery looking radiant.

How to Clean Gold Jewellery at Home
1. To clean your gold jewellery at home, soak the piece in warm water with a few drops of mild, non-moisturising dish soap.
2. After 10–15 minutes, use a soft-bristled toothbrush to gently clean the surface, especially around any settings or intricate details.
3. Rinse thoroughly and dry with a soft, lint-free cloth. This method is safe for yellow gold rings, white gold necklaces,
rose gold earrings, and other fine jewellery.
4. Avoid abrasive materials, harsh chemicals, or commercial cleaners not specifically formulated for gold—especially if the piece includes diamonds, gemstones, or finishes like rhodium plating.

Gold Jewellery Scratches and Professional Cleaning
Over time, all gold jewellery—particularly rings and cuffs—may develop fine scratches or a soft patina from wear. While these marks are part of the character of gold, some clients prefer to restore their jewellery to a high-polish finish.
In these cases, professional polishing is recommended to remove superficial scratches.To preserve the integrity of the piece, polishing should only be done occasionally throughout the life of the jewellery.

How to Untangle a Necklace

Even the most delicate and well-loved necklace can occasionally become tangled.
Whether it's a fine gold chain or a diamond-set pendant, untangling a necklace requires patience, a soft touch, and the right technique.

Step-by-Step: How to Untangle a Necklace at Home

  1. Lay it Flat – Place the necklace on a clean, flat surface with good lighting. A jewellery tray or a soft cloth works well to prevent scratching.
  2. Add a Little Lubrication – Apply a tiny drop of baby oil, olive oil, or even talcum powder to the knot. This helps reduce friction and allows the links to move more freely.
  3. Use a Fine Pin or Needle – Using a pair of sewing pins or a safety pin, gently tease apart the knot. Work slowly, easing the links apart without pulling.
  4. Be Gentle – Never tug or pull—this can damage delicate chain links or stretch fine metal. Patience is key.
  5. Rinse and Clean – If you’ve used oil or powder, clean the necklace gently with mild soapy water and pat it dry with a soft cloth.

When to Ask a Professional
If your necklace is particularly valuable, features fine diamonds or gemstones, or is tightly knotted, we recommend not taking risks at home.
Our specialists in Canturi boutiques in Sydney, Melbourne and Brisbane are trained in the care and handling of fine jewellery and can assist with safely untangling delicate chains or intricate settings.

Engagement Rings

How to Choose an Engagement Ring

Choosing an engagement ring is a deeply personal decision, reflecting love, identity, and commitment. From selecting between natural diamonds and gemstones to finding a design that truly resonates, expert guidance can help you navigate this meaningful journey. At Canturi, our specialists provide personalised consultations in our Sydney, Melbourne, and Brisbane boutiques to help you find the perfect ring.
Read our complete guide on How to choose an engagement ring.

How to Choose the Perfect Diamond

Understanding the 4Cs, Cut, Colour, Clarity, and Carat, is essential when choosing a natural diamond for your engagement ring.
These factors determine a diamond’s brilliance, beauty, and value, making GIA certification a crucial element in ensuring authenticity and quality.
At Canturi, we source only the finest natural diamonds through exclusive partnerships with the world’s most respected diamond cutters, ensuring ethical sourcing and exceptional craftsmanship.

A Comparison - Natural vs. Lab-Grown Diamonds

Deciding between a natural or lab-grown diamond engagement ring comes down to your values and long-term vision. At Canturi, we have spent decades guiding clients who seek rare, meaningful, and lasting symbols of love.
While lab-grown diamonds are a trend, natural diamonds retain their value, hold generational significance, and become treasured heirlooms.
If you’re looking for a ring that truly lasts a lifetime, read our complete guide on Natural vs Lab-grown Diamonds.

Does Canturi use 'Conflict-Free' diamonds?

Canturi ensures all diamonds purchased are from those sources that adhere to the Kimberley Process Certification Scheme of the World Diamond Council.
This international system was created to monitor and eliminate the trade of "conflict diamonds". 
It applies to all rough diamond mined since January 1, 2003 and requires these to be sealed in separate containers and accompanied by numbered certificates to guarantee the diamonds are conflict free.
Canturi applies this system guaranteeing that all diamonds being sold are from legitimate sources not involved in funding conflict and in compliance with United Nations resolutions.

Which Hand Do You Wear an Engagement Ring On?

Traditionally, the engagement ring is worn on the fourth finger of the left hand—often called the “ring finger.” This custom stems from an ancient belief that a vein connected that finger directly to the heart.
But around the world, the tradition varies. In many Asian cultures, including China, Japan and India, the engagement ring is often worn on the right hand. The same applies in parts of Eastern Europe and South America, where wearing an engagement ring on the right hand is a long-standing practice.

So, which hand should you wear your engagement ring on? 
The answer is beautifully personal. Whether you follow tradition or your own instinct, the most important thing is that your ring feels right for you.

At Canturi, we honour the diversity of customs and the individuality of our clients—each engagement ring is designed to reflect the wearer, no matter which hand it's worn on.

Can Men Wear Engagement Rings?

Absolutely—and more men are choosing to wear engagement rings than ever before.
Whether as a symbol of love, equality, or personal style, an engagement ring is simply a meaningful way to mark a commitment—no matter your gender.

Canturi is a destination for Men’s fine jewellery. Stylish clients including Troye Sivan and celebrity stylist Marc Forné choose Canturi for our refined, architectural designs and confident simplicity.
