Many buyers now choose to buy lab grown diamonds Australia because they offer the same physical and optical properties as mined diamonds at a more accessible price. Modern technology produces these diamonds under controlled conditions that replicate the natural formation process. As a result, buyers can enjoy certified diamonds without compromising on appearance or durability.
Whether you are shopping for an engagement ring, earrings, or a custom jewellery piece, understanding how lab grown diamonds are graded and sold helps you make an informed purchase.
Why Buy Lab Grown Diamonds Australia?
Australia has seen growing demand for lab grown diamonds across all jewellery categories. Consumers appreciate the balance between quality, transparency, and value.
A lab grown diamond is made from carbon, just like a natural diamond. It has the same hardness, brilliance, and crystal structure. Independent gem laboratories grade lab grown diamonds using the same standards applied to mined diamonds.
Many Australian jewellers now offer certified stones, including lab-grown options, in a wide range of shapes and sizes. Buyers can compare specifications online or visit showrooms before making a decision to buy lab grown diamonds Australia.
Understanding Lab Grown Diamonds
The term lab grown diamonds refers to diamonds created using advanced manufacturing methods instead of geological processes underground.
Two production methods dominate the industry.
- High Pressure High Temperature (HPHT)
- Chemical Vapor Deposition (CVD)
Both methods produce genuine diamonds rather than diamond simulants. Unlike cubic zirconia or moissanite, lab grown diamonds consist of pure crystallised carbon.
Professional grading laboratories evaluate these diamonds using the well-known Four Cs.
- Cut
- Colour
- Clarity
- Carat weight
These factors influence both appearance and price.
How Certification Protects Your Purchase
Certification gives buyers confidence in a diamond’s quality.
Reputable laboratories examine each diamond under controlled conditions and issue a grading report that describes its characteristics. A certificate typically includes measurements, colour grade, clarity grade, cut grade, fluorescence, and identifying information.
Many certified lab grown diamonds also feature a microscopic laser inscription that matches the grading report.
Always ask for certification before purchasing a diamond, especially for engagement jewellery.
Buy Lab Grown Diamonds Australia for Better Value
One reason many Australians choose lab grown diamonds is price.
A lab grown diamond usually costs significantly less than a mined diamond with comparable specifications. Savings vary depending on carat weight, cut quality, and market conditions. Lower prices allow buyers to select a larger stone or a higher colour and clarity grade within the same budget.
This value makes lab grown diamonds particularly attractive for engagement rings and anniversary gifts.
Choosing the Right Diamond Shape
Diamond shape affects both style and brilliance.
The most popular option remains the round brilliant cut diamond engagement ring because the cut maximises light return. Its symmetrical design creates exceptional sparkle and suits both traditional and contemporary settings.
Other popular shapes include:
- Oval
- Cushion
- Emerald
- Princess
- Pear
- Radiant
- Marquise
Each shape offers a distinct appearance. Elongated shapes can make the diamond appear larger, while square cuts provide a modern look.
How Many Facets in a Round Brilliant Cut Diamond?
Many buyers ask, how many facets in a round brilliant cut diamond?
The modern round brilliant cut typically features 57 facets if the culet is absent. If the diamond includes a culet facet, the total becomes 58 facets.
These carefully positioned facets reflect and refract light throughout the stone. Proper facet alignment contributes to brilliance, fire, and scintillation.
Another common question is how many facets does a round brilliant cut diamond have. The answer depends on whether the culet is included, but the standard design contains either 57 or 58 facets.
This cutting style remains the benchmark for maximum sparkle because every facet serves a specific optical purpose.
Understanding the Four Cs Before Buying
Comparing diamonds becomes much easier when you understand the grading system.
Cut
Cut determines how efficiently a diamond reflects light. An excellent cut often appears brighter than a larger diamond with poor proportions.
Colour
Colour grades generally range from D to Z.
Diamonds graded D to F appear colourless. G to J diamonds offer excellent value because slight colour differences remain difficult to detect without comparison.
Clarity
Clarity measures internal inclusions and external blemishes.
Many diamonds with VS or SI clarity appear eye-clean, meaning imperfections cannot be seen without magnification.
Carat Weight
Carat measures weight rather than size.
Two diamonds with identical carat weights may appear different depending on their proportions and cut quality.
Tips for Buying Online in Australia
Online shopping gives buyers access to larger inventories and competitive pricing.
Before placing an order, compare several certified diamonds with similar specifications. Read the grading reports carefully instead of relying only on photographs.
Check these details before purchasing:
- Independent certification
- Clear return policy
- Warranty information
- High-resolution images or videos
- Secure payment options
- Australian consumer protections
A reputable retailer should answer technical questions about grading, origin, and manufacturing methods.
Selecting the Right Ring Setting
The setting influences both appearance and durability.
A solitaire setting highlights the diamond without distractions. A halo setting surrounds the centre stone with smaller diamonds to create greater visual impact. Three-stone rings symbolise the past, present, and future, while pavé settings add sparkle along the band.
Metal choice also matters.
Platinum offers excellent durability and naturally white colour. White gold provides a similar appearance at a lower cost. Yellow gold creates a classic contrast, while rose gold adds warmth and a distinctive style.
Caring for Lab Grown Diamonds
Lab grown diamonds require the same care as mined diamonds.
Clean jewellery regularly using warm water, mild soap, and a soft brush. Rinse thoroughly and dry with a lint-free cloth.
Avoid exposing jewellery to harsh chemicals during cleaning or gardening. Store each piece separately to prevent scratches from contact with other jewellery.
Professional inspections every year help ensure that prongs remain secure and the stone stays safely mounted.
Common Questions Buyers Ask
Many first-time buyers want reassurance before making a purchase.
Lab grown diamonds are genuine diamonds, not imitations. They receive professional grading, display the same hardness as mined diamonds, and can last for generations with proper care.
Another common question involves resale value. Like many luxury goods, resale prices depend on market demand, certification, quality, and condition. Buyers should view jewellery primarily as a personal purchase rather than an investment.
