What is a triangular diamond?
A triangular diamond is a triangular shaped stone, distinguished by its angular design, which symbolises strength, uniqueness and modernity.

A diamond is not just a jewellery piece
A diamond is more than a stone – it is a symbol of love, stability and lasting value. An unpolished diamond is valuable even before it is cut and polished. In the world of gemstones, diamonds occupy an exceptional place due to their physical properties, visual impact and emotional significance.
Diamond and brilliant-cut diamond – what is the difference?
A brilliant-cut diamond is a specifically cut diamond, usually Round in shape with 57–58 facets, which maximally reflect light. A triangular diamond is a different shape, but can also be brilliant-cut, if the principle of light refraction is maintained.
Brilliant-cut diamond or diamond: what is the difference?
A diamond is a natural mineral, while a brilliant-cut diamond is a diamond cut in a specific way. Thus, a brilliant-cut diamond and a diamond are not the same, but a brilliant-cut diamond is a diamond.
Triangular shape and its uniqueness
Triangular diamonds feature 3 symmetrical sides, created for maximum light reflection. They are ideal both as solitary stones, and as side stones for the main brilliant-cut diamond.
Diamond and its properties
A diamond is the hardest natural gemstone, rated 10 on the Mohs scale. It is resistant to wear, therefore particularly suitable for everyday jewellery pieces – rings, earrings, pendants.
1ct brilliant-cut diamond price

The value of brilliant-cut diamonds heavily depends on their certification, which ensures that the stone meets high quality standards. The triangular shape due to its cut specifics can have a slightly lower price than Round brilliant-cut diamonds, but it heavily depends on the cut quality.
Diamond and clarity
Clarity and transparency are some of the most important criteria when evaluating a diamond. The fewer inclusions a stone has, the higher its quality and value. The quality of a gemstone is determined with the help of GIA and IGI certificates.
Certified diamonds: why is it important?
Certified diamonds are evaluated according to official standards, indicating colour, clarity, cut and other parameters. Certification allows comparing different diamonds based on objective criteria.

Meanwhile, triangular shaped diamonds are less common, making them ideal for those who want something unique.
