Diamonds are the most desirable stones in jewelry – they are rare, captivate with their brilliance and perfection. However, it is worth knowing that both the prices of diamonds themselves and the jewelry in which they are found can differ significantly, even if these items appear almost identical at first glance. What determines the price of a diamond, and what markings should be paid attention to when looking for the perfect diamond?
Diamond vs. diamond – what is the difference?
The interchangeable use of the terms “brilliant” and “diamond” is common. However, it is worth knowing that this nomenclature does not refer to the same jewelry product. A diamond is a very rare gemstone, being a crystalline form of carbon. It is the hardest mineral in the world, formed in the deep layers of the Earth’s crust under the influence of high pressure and temperature. This process takes millions of years.Diamonds have a matte surface and only after undergoing jewelry processing can they be called brilliant cuts. Brilliants owe their name to the most commonly used diamond cut, which allows the stone to reveal its perfect sparkle. The brilliant cut, considered the pinnacle of jewelry artistry, makes the stone perfectly symmetrical and round and has a minimum of 58 facets.
Engagement ring with a brilliant diamond – a symbol of love
The popularity of diamonds in engagement jewelry is primarily due to their symbolism. The diamond, from which diamonds are made, is a symbol of perfection, indestructibility, and purity. In relation to the feelings connecting future spouses, a diamond symbolizes fidelity and the unbreakable nature of the relationship. A diamond set in a ring is not only a beautiful gift but also a declaration of love and a statement of the desire to spend the rest of life with one’s chosen partner. For this reason, it is worth taking a closer look at the stones set in jewelry in order to choose the perfect diamond.
The Four Cs, or the basic criteria for evaluating diamonds
Most people, when dealing with diamonds, primarily pay attention to their size. However, considering only this aspect, we may be surprised by the fact that stones of the same size can differ significantly in price. The weight of the stones is not the only determinant of their value, which is why it is worth learning to read the jewelry markings of different criteria for evaluating gemstones.
The basic criteria, which are the global market standard determining the estimated value of diamonds, are known as the “4C” principle, whose name comes from the first letters of the English words describing the individual parameters of the stones.
- Carat Weight
Carat (ct) is a unit that specifies the weight of gemstones and equals 0.2 g. Its name comes from the plant Ceratonia siliqua L., whose small and almost identical seeds were used in ancient Greece as weights to measure the weight of metals and gemstones. It is worth noting that two diamonds weighing 0.20 ct each will be cheaper than one stone weighing 0.40 ct with the same parameters, due to the rarity of larger stones.
- Colour
The color of diamonds, professionally classified as shades of white, is most often in the range from transparency to yellowish or brownish tint. The highest-rated diamonds are completely transparent – marked with the letter D. However, these are rare (similarly to stones with clarity E and F, included in the same clarity group). Almost colorless diamonds are those marked as G, H, I-J; the next group is toned white (Faint Yellow) K-M, then toned (Very Light Yellow) N-R, and finally slightly darkened (Light Yellow) S-Z.
The best value for money is considered to be diamonds combining H color (white) and SI clarity (inclusions not visible to the naked eye).
- Clarity
The clarity of a stone is another parameter that determines its price. When assessing the clarity of stones, both inclusions (internal imperfections, called ‘needles’) and blemishes (external features) are taken into account. The arrangement of these microscopic imperfections has a significant impact on the light refraction effect (brilliance), so the fewer and smaller they are, the more valuable the specimen. The clarity of stones is evaluated under multiple magnifications.Perfectly clean diamonds marked as LC (Loupe Clean) are rare. The next clarity grades are: VVS – very, very small inclusions, VS – very small inclusions, SI – small inclusions, invisible to the naked eye, and P, which means inclusions noticeable to the naked eye.
- Cut
The cut of a stone, in turn, is a criterion directly related to the jeweler’s craftsmanship. It is worth knowing that an incorrect cut can cause even a 50% loss in the stone’s value. A full brilliant cut consists of 56 facets, the table, and the culet. The evaluation of the stone’s cut involves analyzing the proportions, finish, and symmetry of the diamond. It is presented on a 5-point scale: Excellent (EX), Very Good (VG), Good (G), Fair (F), and Poor (P).
Certified Diamonds – Beauty and Investment
Of course, proper independent evaluation of diamonds is unattainable for most people, which is why, when choosing the perfect diamond, it is worth deciding to purchase only one whose quality is confirmed by a reliable certificate, guaranteeing its authenticity and value. Diamond certificates are issued by the most renowned gemological institutes in the world.These include: IGI (International Gemological Institute), GIA (Gemological Institute of America), EGL (European Gemological Laboratory), HRD (The Hoge Raad voor de Diamant), and DPL (Diamant Prüflabor GmbH).
Custom jewelry – a unique gift
The exceptional sparkle, flawless cut, and perfect clarity of a diamond, along with its symbolic significance, make a diamond ring the most popular engagement gift. If you want to find a truly unique model, it is worth opting for a custom design. Custom engagement rings allow for personalization of the gift and its full adaptation to the fiancée’s preferences.
