You can not open a women’s magazine without stumbling upon an article about colored diamonds.
New darling of American 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 investment in a colored diamond. 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 colored diamond
Unlike the white diamond, the more the color is marked, the more the stone is rare and expensive. The color of the 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 investment, we recommend the hues “intense” or “vivid”. These 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 white diamond and the “light fancy pink”, 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 …
The most at least rare colors: Red (some stones every year only), green, blue, pink, orange and finally yellow.
“Fancy vivid yellow” = the color of “daffodil diamonds” you’ve probably heard about.
For an investment: It all depends on your financial means: the red is untouchable to me and corresponds to a separate market: Example: US $ 2,667,567 dollars for 2,26 carats at Christie’s in November 2007 (buyer Laurence Graff)
Green is rarely intense. Beautiful blue diamonds are very rare and the stones are usually treated, absolutely avoid for placement.
The intense yellow is an established color and the risk of falling prices is very low.
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.
For the pink diamond of very good quality, there is only one address: the Argyle mine in Australia.
It is imperative to buy a GIA certified pink diamond because treatments, (heating, irradiation) are numerous. On the certificates, we can sometimes read as a qualifier for the color: “Brown Pink” or “Grayish Yellow”.
This implies that you can have either two shades of colors in the same stone or a dominant color with a different color.
Are these stones to be evicted? For the manufacture of a jewel: no, because some composite colors are very beautiful (orangy yellow for example) and stones are cheaper than when the color is unique.
For an 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.
Everything is a question of budget. Avoid stones that are too small as far as possible. If your budget does not allow you: change color or change stone placement, (Tanzanite, Rubellite)
The colored diamond is so expensive that you will find all the possible shapes on the market.
The lapidary optimizes the raw to make a maximum of weight and “out” the most beautiful color possible.
Do not look for a classic round cut. Colored diamonds are insider stones that can be sensitive to a nice radiant size or a nice pear for example. Avoid the shuttle size that is out of fashion.
Attention, however, the quality of the size that may have been sacrificed by the lapidary always for the same reasons. Do not buy a stone cut too thick or on the contrary, very spread out, a shuttle cut in lamella or a pear, “super drop”, cut lengthwise. Avoid very big rounders or microscopic tables.
Your stone must shine brightly, if it is not the case, run away.
