The price of a pear diamond is determined by its carat, purity, color and therefore its size. In this case, the pear cut here.
For example, for a diamond of color D and purity IF or FL of 1.00 carat, the price will vary between 10,000 and 20,000 euros per stone.
The price is always calculated based on the 4Cs. These criteria are essential to calculate the price of a diamond.
Without a certificate of authenticity, it is more difficult to evaluate the price of a diamond, especially if it is old.
The certificate is an identity card for the diamond, without it, it is difficult to give an accurate estimate. In this case, depending on the jewelry stores where you would bring your diamond, there will be a price difference announced on the estimate.
The price of a round brilliant diamond will always be higher than that of a pear diamond of equal weight. As the demand for round-brilliant diamonds is stronger than that of the pear, its price is necessarily affected. It is therefore more economical to buy a pear shape if your budget is limited.
● The value of a diamond is not proportional to weight: A 1.00 carat diamond will not be 2 times more expensive than a 0.50 carat diamond.
● The color of the diamond also influences its value, the whitest color is D, a Z diamond will have a yellow tint visible to the naked eye.
● Purity is essential to determine the value of the diamond: A scale has been developed by diamond dealers to define diamonds with a lot or conversely few impurities. The cleaner the diamond, the more expensive its price will be
Other criteria:
● The quality of the cut: A diamond ideally cut will have more value than a poorly cut or poorly proportioned diamond. A poorly cut diamond will be recut to resell more easily and gain value, but it will lose weight and therefore its carat will be reduced.
● The polish or symmetry: If the diamond is not symmetrical it will lose up to 10% of its value. Specifically for the pear cut whose symmetry must be perfect.
● Fluorescence: Fluorescence is seen thanks to an ultra-violet ray. If a diamond has a lot of fluorescence it will generally be milky therefore less sought after by consumers.
In a market where prices are dictated by supply and demand, customers are looking for a diamond with little or no fluorescence.
● The gemology certificate: A diamond that does not have a certificate will be much harder to estimate.
