Diamond Full Guide
The Diamond: An Eternal Stone
For centuries, the diamond has symbolized purity, light, and commitment.
Its natural rarity and incomparable brilliance make it the most iconic gemstone in fine jewelry.
At GEMNAT, we work exclusively with 100% natural diamonds, carefully selected for their beauty, balance, and individuality.
Each diamond is shaped by the Earth itself over billions of years.

What Is a Diamond?
A diamond is composed of pure crystallized carbon.
It forms more than 150 kilometers beneath the Earth’s surface under extreme pressure and temperature.It is the hardest natural substance known, ranking 10 on the Mohs scale of hardness.
This exceptional durability allows it to withstand the passage of time without losing its brilliance.
A diamond is eternal, symbolically and physically.
About
The 4Cs of a Diamond
A diamond’s quality and value are determined by four universal criteria known as the 4Cs.

Carat – Weight
Carat measures the weight of a diamond.
One carat equals 0.20 grams.
The higher the carat, the rarer the stone.
However, proportions and cut significantly influence how large the diamond appears visually.

Color – Purity of Hue
White diamonds are graded on a scale from D (colorless) to Z (noticeable yellow tint).
The most rare diamonds are completely colorless.
Slightly warmer tones can offer a subtle balance between brilliance and character.

Cut – Brilliance
Cut is the most important factor affecting a diamond’s sparkle.
A perfectly proportioned cut allows light to enter the stone, reflect internally, and return with maximum brilliance.
A well-cut diamond will shine more than a heavier diamond with poor proportions.

Clarity – Natural Purity
Clarity refers to the presence of natural inclusions formed during the diamond’s creation.
Most inclusions are invisible to the naked eye.
A slightly included diamond may appear visually identical to a flawless one without magnification.Each natural diamond carries its own internal signature a trace of its geological origin.

Certification
A diamond may be accompanied by a certificate issued by an independent gemological laboratory such as:
- Gemological Institute of America (GIA)
- International Gemological Institute (IGI)
This document precisely details the diamond’s 4Cs and guarantees its characteristics.
At GEMNAT, each piece is delivered with a certificate confirming the specifications of the selected stone.
FAQ
Are GEMNAT diamonds natural?
Yes.
At GEMNAT, we work exclusively with 100% natural diamonds, formed within the Earth over billions of years. Their origin and authenticity are guaranteed.
Can you see the difference between natural and lab-grown diamonds?
To the naked eye, they can appear similar.
However, only specialized gemological equipment can determine a diamond’s origin.At GEMNAT, every diamond is natural and carefully selected.
What is the most important of the 4Cs?
All four criteria matter, but cut has the greatest impact on brilliance.
A perfectly proportioned cut allows maximum light return, enhancing sparkle and fire.
Does a higher carat mean a better diamond?
Not necessarily.
Carat measures weight, not beauty. A well-cut smaller diamond can appear more brilliant than a larger one with poor proportions.Balance between the 4Cs is key.
What clarity grade is considered “good”?
Most inclusions are invisible to the naked eye.
Grades such as VS or even some SI diamonds can appear perfectly clean without magnification.
Why do diamond prices vary so much?
Pricing depends on:
- Carat weight
- Cut quality
- Color grade
- Clarity grade
- Overall rarity
Even small differences in grading can significantly affect value.
Do diamonds lose their sparkle over time?
No.
Diamonds do not lose brilliance. They may accumulate residue from daily wear, but professional cleaning restores their full sparkle.

What Customers Are Saying
Very highly recommended jewelers who provide an excellent service and expert guidance on creating bespoke jewelry as well as a huge selection of other bracelets, necklaces, earrings and rings.
Very happy, would order again!!
Very happy with this ring for my wife. I keep coming back to Gemnat because their quality and prices are hard to beat. They are a lot more cheaper than other online websites I have checked but the quality is just the same or even better. I highly recommend them to everyone who wants a great quality of jewelry. I'm already planning my next purchase with them hihi
User-friendly website and secure checkout.
Top notch. I've ordered from Gemnat twice and the product and the service level is always flawless.
Luxury Service + Quality
This was my first time buying fine jewelry online and I had zero clue what I was doing 😅. I picked out a morganite ring and was worried about how it would look in real life. When it arrived, I was completely blown away!! The stone sparkles more than I expected, the band is perfect, and the packaging is so elegant! The team even helped me with sizing questions via chat. I’m officially hooked on Gemnat!
This ring went beyond my expectations. Stunning and perfectly crafted.
she said YES!
This ring looked even more stunning in person, just like my now-fiancée. She said YES, shed a few happy tears, and hasn’t stopped admiring it since. We couldn’t be happier. Thank you, GEMNAT! The resizing process was also effortless, thanks to the convenient online chat support.
I AM ALWAYS IMPRESSED!!
This is my third purchase from Gemnat and I’m still amazed 😍. Each piece is gorgeous, shipping is fast, and their customer service is super friendly. Definitely my go-to for jewelry now!

These earrings are so simple but legit sparkle like crazy. Perfect for everyday or when I wanna look fancy. Website was smooth, shipped fast. Obsessed.
There customer service is very very patient when I had a problem with resizing. The ring that I order was a bit smaller but no need to worry since they had it resized for me. Everything was SMOOTH. Will definitely order from this shop again for sure.
The website is so user-friendly. You can easily access everything you want from rings, bracelets, pendants and earrings even wedding rings. They even sort out the colour of stones for buyers. All the designs are super nice it even makes me had a hard time to choose what to buy but I really wanted a tennis bracelet during that time but would probably buy a ring for my girl next time. They are highly recommended!! Customer service was nice because I have to make some adjustments with the chain length and they were patient on every process. Fast replies. Thank you, GEMNAT!!!
