The Short Answer: Yes — With the Right Care
Lab-grown diamonds are physically and chemically identical to mined diamonds. They are graded on the same Gemological Institute of America (GIA) or International Gemological Institute (IGI) scale, and they share the same Mohs hardness of 10 — the highest rating possible. That hardness means a lab-grown diamond resists scratching from virtually any material it encounters in daily life.
However, hardness is only part of the story. A diamond's long-term wearability also depends on its setting, the metal holding it in place, your daily activities, and how consistently you care for the piece. This guide addresses each of those factors directly.
Stone Durability: What Hardness Actually Means
A Mohs 10 rating means a diamond will not be scratched by keys, countertops, or common metals. What it does not mean is that a diamond is indestructible. Diamonds can chip or cleave along natural crystal planes if struck sharply at the right angle — particularly on facet edges and pointed cuts such as princess, marquise, or pear shapes.
A few things to understand about daily stone durability:
- Round brilliant cuts have no sharp corners, making them the most resistant to chipping at the girdle edge.
- Fancy shapes (pear, marquise, emerald) have edges or corners that are more exposed; a well-designed bezel or V-tip prong adds meaningful protection.
- Surface build-up — from lotion, soap film, and natural skin oils — does not damage the diamond, but it significantly dulls its brilliance over time. Regular cleaning restores the light return.

Prong Checks: The Most Overlooked Maintenance Step
The prongs — those small metal claws gripping your diamond — are the single most important factor in keeping the stone secure during daily wear. Metal is softer than diamond, and prongs gradually wear down through contact with surfaces, fabric, and other objects.
Signs that prongs need attention:
- A prong tip catches on fabric or hair when you run your finger over it.
- The prong appears visibly flattened, thinned, or bent when viewed under good light.
- The stone shifts slightly when you gently press it from opposite sides.
- You can see a gap between the prong and the diamond's girdle.
Recommended schedule: Have prongs inspected by a qualified jeweller every 12 months if you wear the ring daily. Rings worn 24/7 in active or manual-work settings may benefit from a six-month inspection cycle.
Do not attempt to re-tip or tighten prongs yourself. Incorrect pressure can crack the diamond at the girdle or distort the setting geometry.
Cleaning: Keeping Brilliance Where It Belongs
A clean diamond reflects light as its cut was designed to. A coated one does not. The good news is that routine cleaning requires nothing more than what you likely already have at home.
At-Home Cleaning Method
- Mix a few drops of mild dish soap (fragrance-free, no moisturiser) with warm — not hot — water in a small bowl.
- Place the ring in the solution and allow it to soak for 20–30 minutes.
- Use a soft-bristled toothbrush to gently scrub under the stone, around the prongs, and along the band. Pay particular attention to the underside of the setting, where the most build-up occurs.
- Rinse under warm running water. Use a sink strainer or hold the ring firmly — do not rinse over an open drain.
- Pat dry with a lint-free cloth and allow to air-dry fully before storing.
What to Avoid
- Ultrasonic cleaners: Safe for diamonds in good condition, but can loosen stones in prong settings that already have worn metal — confirm with your jeweller first.
- Steam cleaners: High-pressure steam can displace stones in delicate settings.
- Bleach, acetone, and chlorine-based cleaners: These degrade gold alloys and can weaken prong metal over time.
- Abrasive cloths or toothpaste: Will scratch the metal surface of the band.
Frequency: A quick soak and brush every two to three weeks is sufficient for rings worn daily. Increase frequency if you apply hand lotion, sunscreen, or perfume regularly.
Activities to Avoid While Wearing Your Ring
Knowing when to remove your ring is as important as how you clean it. The situations below create the highest risk of stone chipping, prong damage, or metal deformation:
- Gym and weightlifting: Grip equipment puts direct lateral pressure on prongs and can bend thinner bands.
- Swimming (pools and sea): Chlorine accelerates metal fatigue in gold alloys. Cold seawater also causes fingers to contract, increasing the risk of the ring slipping off unnoticed.
- Gardening and manual work: Soil, grit, and tool impacts are among the most common causes of prong damage seen by jewellers.
- Applying lotions, perfumes, and hairspray: Apply these before putting on your ring, not after.
- Sleeping: Consistent pressure from bedding can slowly bend prongs over months, particularly on thinner claw settings. Removing the ring overnight is a simple habit that meaningfully extends prong life.
A small ring dish beside the sink and one on the bedside table are low-effort solutions that prevent the majority of avoidable damage.
When to Seek Professional Service
Some maintenance tasks require professional tools and expertise. Bring your ring to a qualified jeweller when you notice any of the following:
- A prong is visibly bent, missing a tip, or no longer making full contact with the stone.
- The stone appears loose or rotates within the setting.
- The band has a visible dent, crack, or thinned section.
- The ring no longer sits level on the finger — a sign the shank has deformed.
- You notice a chip or nick on a facet edge, which can be polished out if caught early.
Professional services to ask about include prong re-tipping, rhodium plating (for white gold bands that have yellowed), band resizing, and full cleaning with ultrasonic and steam equipment under controlled conditions.
As a general rule: if you are uncertain whether something needs attention, have it inspected. The cost of a prong inspection is a fraction of the cost of replacing a lost stone.
Choosing a Ring Built for Daily Wear
The best long-term outcome starts with a setting designed for the cut you love. At IZI, every ring in our lab-grown diamond collection is built with setting integrity in mind — from the gauge of the prong wire to the depth of the seat cut that holds the stone in place.
A few examples from our current collection:
- The Round Brilliant Lab Grown Diamond Ring – 3.32 ct in 18K White Gold pairs the most durable cut geometry with a four-prong solitaire — a combination well-suited to full-time wear.
- The Cushion-Cut Lab Grown Diamond Ring – 2.92 ct in 18K White Gold uses a four-prong setting that protects the cut corners characteristic of the cushion shape.
- The Pear-Cut Lab Grown Diamond Ring – 3.16 ct in 18K White Gold features a V-tip prong at the point — the most vulnerable part of a pear-cut stone — for targeted protection.
- The Emerald-Cut Lab Grown Diamond Ring – 2.13 ct in 18K White Gold sits in a step-cut optimised setting that showcases the stone's hall-of-mirrors effect while securing all four corners.

A Practical Summary
- Lab-grown diamonds are Mohs 10 — they will not scratch in daily life, but can chip on a hard, sharp impact.
- Prongs are the weakest link in any ring: inspect them annually, or every six months for active wearers.
- Clean with warm soapy water and a soft brush every two to three weeks.
- Remove your ring for the gym, swimming, gardening, and sleep.
- Do not wait for a visible problem before visiting a jeweller — a routine inspection costs far less than a lost stone.
