Diamond shape: Choose the perfect gemstone according to your taste
Diamonds are considered the most valuable gemstones, but their appearance can vary greatly depending on their shape and cut. A properly chosen diamond shape not only enhances the stone’s beauty but can also significantly alter the gemstone’s value. If you are considering buying diamonds, in this article you will find everything you need to know about diamond shapes, their differences, known cuts, and how to choose the ideal stone according to your needs. Discover the different diamond shapes and selection options we will discuss in this article.
What is a diamond and a brilliant-cut diamond?
Often, a diamond and a brilliant-cut diamond are confused, but there is a fundamental difference between them. A diamond is a gemstone mined from carbon, which features incredible hardness and brilliance properties. A brilliant-cut diamond is a special diamond cut, known as a brilliant cut, which means a traditional round shape with 57 or 58 facets, designed to maximise light reflection and fire. Brilliant-cut diamonds are especially valued for their precise cut and exceptional brilliance. The classification of brilliant-cut diamonds depends on the cut quality, symmetry, and other evaluation criteria. For a diamond to become a brilliant-cut diamond, special processing and techniques are applied to achieve the desired shape, clarity, and brilliance. Thus, a brilliant-cut diamond is a diamond shape, but not all diamonds are brilliant-cut diamonds.

Gemstones: the place of diamonds among other gemstones
A diamond is one of the most valued gemstones in the world, standing out for its unique beauty and lasting value. Among other gemstones, such as rubies, sapphires, or emeralds, diamonds differ not only in their exceptional brilliance but also in their extraordinary hardness – a diamond is the hardest natural stone, making it very resistant to daily wear. Diamonds can be chosen in various shapes – from the classic round to heart or oval shapes, so everyone can find the most suitable option for their taste. Moreover, diamonds are evaluated by their colour, clarity, and carats, and their versatility allows them to be used both in luxury jewellery and as an investment asset. Since ancient times, a diamond has symbolised love, exclusivity, and luxury, and thus remains one of the most desired stones among all gemstones to this day.

Diamond value: what determines the price and investment potential?
The value and price of diamonds depend on many factors, so each diamond is unique. The most important criteria by which diamonds are evaluated are clarity, colour, carats, and shape. The higher the clarity level, the whiter the colour, and the larger the carats, the higher the price of the diamond can be. It is also very important whether the diamond is certified – GIA, HRD, or IGI certificates ensure that the stone meets the highest quality standards and is accurately evaluated. Certified diamonds are valued more, as their properties are reliably confirmed. The price of diamonds also depends on market demand and supply, making them a great long-term investment. Diamonds are often chosen as an alternative to traditional investments because their value remains stable even during economic fluctuations. By investing in diamonds, you can be sure that you are acquiring not only an exceptional gemstone but also an asset that retains its value over time.
Lab-grown diamonds: a modern alternative
Modern technologies allow the creation of lab-grown diamonds, the properties of which hardly differ from natural diamonds. Such diamonds are a great alternative for those looking for a sustainable and environmentally friendly choice. Lab-grown diamonds are significantly lower in price than natural ones, but their quality, brilliance, and appearance remain the same. This is an excellent solution for those who want to purchase a diamond but do not want or cannot invest in a natural stone. In addition, lab-grown diamonds are increasingly valued for their ethical origin and the possibility to choose from various shapes and sizes.
Diamond care: how to maintain brilliance
For diamonds to remain sparkling and not lose their value, it is essential to care for them properly. Although diamonds are very hard, they can be damaged if carelessly cleaned or stored together with other diamonds. It is recommended to clean diamonds regularly with mild soapy water and a soft brush, avoiding strong chemicals. It is also important to store diamonds separately from other diamonds so they do not scratch each other. If you notice that a diamond has lost its brilliance or looks damaged, it is worth contacting professionals who can perform an inspection and, if necessary, restore the stone. Proper diamond care will ensure that your gemstones always look flawless.
It is also important to mention that the delivery of our diamonds and jewellery is carried out safely and with high quality, so they reach the customer in perfect condition.
Each diamond is unique
Although choosing a diamond shape can be difficult, the most important thing is to remember that each diamond is unique. Its shape, colour, and quality contribute to what price will be offered for this gemstone. Additionally, the choice of a diamond may depend on your personal preferences and the projected use of the jewellery pieces.
