You can not open a women’s magazine without stumbling upon an article about pink diamonds.
New darling of stars, the colored diamond has become the “must have” when it comes to choosing his engagement ring for the “happy few” on the planet.
Is it a simple fashion effect, or on the contrary a phenomenon that has all the chances of continuing thus justifying the pink diamond investment. Which criteria should be favored? Which are the rarest colors, and which ones, in our opinion, should take the most value?
What gives diamonds their color?
The diamond made of pure carbon is white. The color comes from the presence of impurities in the atomic structure of the stone. Simply put, boron gives blue, yellow nitrogen, rose or red hydrogen (sometimes gray), and uranium gives green.
What are the criteria for qualifying the quality of a pink diamond?
Unlike the pink diamond, the more the color is marked, the more the stone is rare and expensive. The color of the pink diamond is qualified for its intensity, its saturation and its homogeneity.
- The color criteria, staggered from least to best, are qualified by the laboratories as follows:
- Very light fancy, fancy light, fancy, intense fancy and fancy vivid
We sometimes meet the qualifiers: fancy dark or fancy deep: dark colors to avoid.
For a purchase pink diamonds investment, we recommend the hues “intense” or “vivid”. These pink diamonds are already very expensive but their rarity is real, the prices are based on tangible elements and they will necessarily take value over time. Stones of high quality, will be, moreover, easier to resell.
Flee the colors “light Fancy”. The “light fancy yellow” color fade that can be likened to a bad color of pink diamond, too expensive for a pink color barely noticeable.
If you like pink diamonds, buy a beautiful pink tourmaline, another stone placement that has made x3 this year since the Chinese take all the crude from Mozambique, but that’s another story …
Green is rarely intense. Beautiful pink diamonds are very rare and the stones are usually treated, absolutely avoid for placement.
The best in my opinion: the pink diamond because it is the most beautiful color for many. Their price goes up every year but there is no reason for it to stop.
It is imperative to buy a GIA certified diamond because treatments, (heating, irradiation) are numerous. On the certificates, Argyle Diamond Investments can sometimes read as a qualifier for the color: “Brown Pink” or “Grayish Yellow”.
This implies that you can have either two shades of color in the same stone or a dominant color with a different color.
Are these diamonds to be evicted? For the manufacture of a jewel: no, because some composite colors are very beautiful (orange yellow for example) and stones are cheaper than when the color is unique.
For a diamonds investment, I would advise against a single color (intense or vivid): “Fancy intense pink” or “Fancy vivid yellow”, for example, are bold colors, easier to understand in the context of a possible resale.
Some colors like blue are very rarely unique.
It is much less important than buying a white diamond, (the most important quality criterion is color). However, avoid stones included, diamonds stitched, which will be difficult to resell to the uninitiated. To give you all the chances of an easy resale, buy a good purity (VS1, VS2). The diamond will be more expensive but you will have no problem to sell it quickly.
On some certificates, the purity of the stone may not have been qualified.
