Pink diamond price – why does color matter so much?
Pink diamond price – this is one of the most common questions asked by customers, fascinated by the unique beauty of these rare stones. Color plays a huge role in valuation – and it's not just about aesthetics. The intensity, uniformity, and rarity of the color have a significant impact on value. A pink diamond can cost from tens of thousands to even several million Polish zlotys!
Pink diamonds are extremely rare. Most of them came from the Australian Argyle mine, which closed in 2020 – meaning their value increases every year. The more intense the pink, the higher the price. Diamonds in the Fancy Vivid Pink shade are the absolute elite of the market.
It is also worth knowing that the color in diamonds is classified from D (colorless) to Z (slightly yellowish). In the case of colored stones like pink, the classification is different and analyzes the intensity of the color: Fancy Light, Fancy, Fancy Intense, Fancy Vivid.
At Diament Expert, you will find pink diamonds with a GIA certificate and a guarantee of the lowest price in Poland. Check our collections and learn more!
Brilliant-cut diamond price and cut – brilliant-cut diamond versus diamond, what you need to know?
The price of brilliant-cut diamonds, including a 0.08 ct diamond price, is an issue that often leads to misunderstandings – many people don't realize that a brilliant-cut diamond is simply a diamond cut in a specific way! It is the cut that makes the stone sparkle and reflect light like a mirror. An ideal cut can significantly increase the value of a diamond.
The brilliant cut is the most popular type of cut – it has 57 or 58 facets and provides maximum brilliance. A diamond of average clarity but an excellent cut can look better (and be more expensive) than a clearer stone with a poor cut.
Quality certificates (e.g., GIA or HRD) classify the cut on a scale from Poor to Excellent. Only stones with a Very Good or Excellent rating should be chosen for high-end jewelry.
Diament Expert offers only brilliant-cut diamonds with the best cut parameters – you can verify everything yourself using 360° photo technology in our database. Trust the experts!
Diamond price – how does origin affect the stone's value?
The price of diamonds varies significantly depending on their origin and how much 1 carat of a diamond costs – whether we are dealing with a natural or laboratory-grown diamond. This difference can be as much as 60%! Although both look identical, they have different emotional and collectible value for the investment and jewelry market.
A natural diamond is a mineral that formed over millions of years deep within the earth under immense pressure. It is rare, unique, and full of symbolism. A laboratory-grown diamond is created in a few weeks using HPHT or CVD technology, under controlled conditions, with an identical chemical composition.
For customers, the 0.08 ct diamond price often matters – and here, lab-grown diamonds win. But for investors, collectors, or people buying for engagement, natural stones have an emotional and prestigious advantage.
At Diament Expert, you have a choice of both types with an authenticity guarantee and certificate – everything clearly described and compared.
Carat to gram conversion – how do carats in diamonds affect the price?
1 carat = 0.2 grams, but to determine how much 1 carat of a diamond costs, don't rely on simple math for valuation. The price does not increase linearly – the larger the stone, the higher the price per carat. That's why a 5-carat diamond can cost not 5x more than a 1-carat diamond, but even 10x more!
The price of a high-quality 1-carat diamond (D/IF) can be 25,000–35,000 PLN, and the price of a 5-carat diamond with the same parameters can reach 500,000 PLN. Large stones are much rarer, and their processing is more difficult.
When buying a diamond, it's also worth knowing about so-called "magic numbers" – for example, the price jumps significantly when exceeding 0.99 ct to 1.00 ct, so it's worth considering buying just below this limit.

How much does a diamond cost – price examples and market comparisons
How much does a diamond cost? From 3,000 PLN to several million – it all depends on the so-called 4Cs: carat, color, clarity, and cut. But there are also other factors: origin, certificate, supplier reputation.
For example:
- 0.3 ct, G, SI1, Very Good – from 3,200 PLN
- 1.0 ct, E, VS2, Excellent – approx. 18,000–25,000 PLN
- 2.0 ct, D, IF, Excellent – over 60,000 PLN
- 5 carat pink diamond, Fancy Vivid Pink – over 1,000,000 PLN
Beware of offers without a certificate or from unverified sellers. The price may be lower, but you don't know what you're buying.
At Diament Expert, you have a guarantee of the lowest price – if you find it cheaper, we'll refund the difference! You can also buy in installments or with a subscription model.
