Lab-Grown Diamonds: The Modern Choice
Diamonds Certified By :
At Finite Jewels, we understand that selecting a diamond is about more than just beauty—it’s about making an informed, ethical, and sustainable choice. Lab-grown diamonds offer an exceptional alternative to mined diamonds, combining cutting-edge technology with timeless elegance.
What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds, created using advanced technology that replicates the natural diamond-growing process. They have the same physical, chemical, and optical properties as mined diamonds — the only difference is their origin.
Why choose lab-grown?
- Ethically sourced
- Environmentally conscious
- Better value for the same sparkle
A lab-grown diamond is created in a controlled environment using advanced technology that replicates the high-pressure, high-temperature conditions under which natural diamonds form deep within the earth. These diamonds are chemically, physically, and optically identical to mined diamonds, meaning they possess the same brilliance, fire, and durability that diamonds are known for.
Despite being indistinguishable from natural diamonds to the naked eye, lab-grown diamonds come at a more affordable price point and are considered a more sustainable and ethical choice. Unlike mined diamonds, which require extensive excavation, lab-grown diamonds have a significantly lower environmental impact, making them a modern, responsible alternative without compromising quality or luxury.
The Key Benefits of Lab-Grown Diamonds
- Exceptional Quality & Beauty – Lab-grown diamonds are held to the same high standards as natural diamonds and undergo rigorous grading based on the 4Cs: Cut, Carat, Clarity, and Colour.
- More Value for Your Money – Because lab-grown diamonds do not require the costly and labor-intensive process of mining, they are typically 30-40% more affordable than their mined counterparts, allowing you to purchase a larger or higher-quality diamond within your budget.
- Sustainable & Ethical – Mined diamonds often involve extensive land disruption and carbon emissions, whereas lab-grown diamonds require far fewer natural resources, can be produced using renewable energy and require significantly less water than mining. Additionally, they are 100% conflict-free, offering peace of mind when making your purchase.
- Identical Composition – Both lab-grown and natural diamonds are made of pure carbon arranged in a crystal lattice structure, ensuring the same hardness (10 on the Mohs scale) and light performance.
- Certified & Graded – Just like natural diamonds, lab-grown diamonds are independently certified by GIA (Gemological Institute of America) and IGI (International Gemological Institute), ensuring transparency and authenticity in every stone.
At Finite Jewels, we take pride in offering premium-quality lab-grown diamonds that provide exceptional brilliance, ethical sourcing, and remarkable value.
Diamond Certifications Guide – Finite Jewels
At Finite Jewels, we know that purchasing a diamond—whether natural or lab-grown—is a significant deal. That’s why every diamond in our collection comes with trusted certification from world-renowned gemological institutes, ensuring complete transparency regarding its quality, authenticity, and value.
Two of the most widely respected certification bodies in the industry are:
- The International Gemological Institute (IGI) – Specializing in lab-grown diamond certification, IGI provides detailed analysis and grading.
- The Gemological Institute of America (GIA) – The gold standard for natural diamond certification, trusted by the world’s top jewellers.
Let’s explore what these certifications mean and why they’re essential when choosing your perfect diamond.
IGI Diamond Certification – Lab-Grown Diamonds
What is IGI?:
The International Gemological Institute (IGI) is one of the most trusted and widely recognized diamond certification authorities worldwide, with over 29 locations across key global markets. It specializes in grading lab-grown diamonds, providing buyers with the confidence that their diamond has been assessed with expert precision.
At Finite Jewels, every lab-grown diamond above 0.30ct comes with an IGI certificate, ensuring complete transparency in its grading and characteristics.
Why Choose an IGI-Certified Diamond?
:
While lab-grown diamonds are visually identical to their natural counterparts, not all diamonds are created equal. This is why certification is critical. An IGI grading report provides an objective, third-party evaluation of the diamond’s quality.
By purchasing an IGI-certified lab diamond, you can be assured that:
✅ You are receiving the quality you paid for
✅ Your diamond has been rigorously assessed for beauty & durability
✅ It meets the highest global industry standards
How Do I Know If My Diamond is IGI Certified?:
Each IGI-certified diamond comes with a unique report number, visible on:
- The physical IGI certificate that accompanies your diamond
- Laser inscription on the diamond’s girdle (visible under 20x magnification)
- Verification via the official IGI website
Understanding the IGI Diamond Grading Report
IGI’s Diamond Grading Report includes a detailed breakdown of your diamond’s characteristics. Below is an overview of what each section means:
1. Diamond Overview:
This section includes:
- Report date
- Diamond shape & cut style

2. Grading Results – The 4Cs
:
This section includes:
- Carat Weight– The diamond’s weight, measured in metric carats.
- Clarity Grade – Evaluates inclusions and blemishes, ranging from IF (Internally Flawless) to I3 (Included, visible imperfections).
- Colour Grade – ERated from D (completely colourless) to Z (noticeable yellow/brown tint).
- Cut Grade – Determines how well the diamond reflects light, impacting its sparkle.
Additional Grading Factors:
- Polish – Measures the smoothness of a diamond’s facets (graded from Excellent to Poor).
- Symmetry – Evaluates how well a diamond’s facets align.
- Fluorescence – A diamond’s reaction to UV light, which can impact appearance & value.
Proportions & Clarity Characteristics

Jewellery Care
Your bespoke jewellery is made to be worn and enjoyed — but with a little care, you can help it stay looking its best for years to come. Below is some simple guidance on how to care for your piece day-to-day, and how to clean it safely at home.
Step-by-step guide
To keep your jewellery looking as good as the day it was made:
- Prepare a cleaning solution – Fill a bowl with warm water and add a small drop of mild dish soap. Avoid anything with harsh chemicals or abrasives.
- Soak the ring– Place your ring in the solution and leave it to soak for around 20–30 minutes. This will loosen any dirt, oil, or residue.
- Gently brush– Using a soft toothbrush, carefully clean around the stone and setting — especially underneath the diamond and around the prongs, where buildup often collects.
- Rinse thoroughly – Run the ring under warm water to wash away soap and loosened debris.
- Dry and polish – Pat dry with a clean, lint-free cloth. If you have a jewellery polishing cloth, you can gently buff the band to restore shine (avoid polishing gemstones directly).
General Care Tips
To keep your jewellery looking as good as the day it was made:
- Avoid exposure to chemicals such as cleaning products, perfumes, hair sprays, or chlorine — these can dull both metal and stones over time.
- Remove your jewellerywhen exercising, swimming, cooking, or cleaning — not only to protect the piece, but also to reduce the chance of accidental knocks or loss.
- Store it properly in a soft-lined box or pouch when not in use, ideally separate from other pieces to prevent scratches.
How to Clean Your Jewellery at Home
Cleaning your ring at home is quick and easy with the right materials — and no need for anything specialist.
You’ll need:
- Mild dish soap.
- Warm water.
- A soft toothbrush or jewellery cleaning brush.
- A soft, lint-free cloth.
- A small bowl or container.
Avoid using
- Household cleaners, bleach or acetone
- Ultrasonic cleaners, unless specifically recommended
- Tissues or paper towels, which can cause micro-scratches
Want a Deeper Clean?
If your jewellery needs a deeper clean or professional check-up, we recommend visiting a reputable local jeweller who offers cleaning services. Most will offer this as a one-off or annual service, especially for engagement rings and pieces worn daily.

How do I care for my jewellery?
Proper care is essential to maintain the brilliance and longevity of your jewellery, it’s important to clean your pieces regularly with a soft cloth, and avoid exposing them to extreme temperatures or harsh chemicals. Contact with these products will make your diamond look grey and dull as they tend to stick to the bottom of the diamond and prevent it sparkling as it should. When not in use, store your jewellery in a soft pouch or lined box to prevent scratches.
What's the difference between lab grown and mined diamonds?
Lab-grown diamonds are created in controlled environments, mirroring the natural process but with significantly less environmental impact. Mined diamonds are formed over millions of years under the earth’s surface. While both types have identical chemical compositions and visual characteristics, lab-grown diamonds are often considered a more ethical and sustainable choice, as they avoid the environmental and social issues associated with traditional mining.
