How to buy a diamond online?

 
Buying a diamond is not a purchase of impulse but a thoughtful purchase: it is important to compare several diamonds and weigh the pros and cons.
 
It is common to hear that to buy a diamond it is better to see it, to be sure of its choice. But the essential is invisible for non-expert eyes. Determining the degrees of whiteness and purity remains a professional job. Many inclusions are invisible to the naked eye without a magnifying glass with X10 magnification and the expert eye of a diamond dealer. And the shades of color are sometimes subtle. It is difficult to evaluate the quality of the brilliance of a diamond without the habit of seeing and comparing it regularly. If you are demanding, choose is after understanding.
 
The characteristics that determine the price and quality of a diamond must therefore be thoroughly explored. They are called 4C: Carat (carat weight), Clarity (degree of purity), Color (degree of white color), Cut (quality of size). On these criteria do not rely on the declarations or certificates of this or that reseller. Always prefer the independent and internationally recognized rating of the 3 most prestigious gemological laboratories: GIA, IGI, HRD.
 
To buy a diamond accompanied by one of these 3 certificates will be for you the guarantee of the authenticity and the quality of your diamond. You will know with certainty what color, what purity is your diamond. You will know the exact weight in carat and all the parameters that define the quality of its size: finish, symmetry ...
 
Beyond the 4C, the 5th C of confidence is just as important. The foundations of this trust are fragile, valuable and based on 3 elements in our opinion: the advice of a diamond dealer, transparency on quality through certificates, and the security of a website regarding payment and delivery methods.

The engagement ring

 
It is the diamond jewel par excellence. And for many, the first purchase of a diamond. Symbol of the rarity and uniqueness of Love, man generally offers a solitary ring, with a single diamond set in the center. Of all the precious stones, the diamond brings to the highest the brilliance and the strength of the amorous feeling. The solitary mount has for mission to put as much value as possible the diamond. Hence the lasting success for decades of the classic diamond claw (4, 5 or 6 claws) whose light and timeless style sublimates the fires of stone set in its center. Most of the solitary diamonds are made with a diamond of brilliant size, of which no other size has been able to dethrone the majesty so far. The round shape is indeed the size that gives the most brilliance to a diamond by the game facets.
 

Wedding alliance

 
There is no marriage without a covenant, a symbol of eternal love because of its ring-like form without beginning and without end. There are many models of wedding rings: all gold without any stone, set with precious stones or precious stones. But the most symbolic is the diamond alliance because it means all the rarity of the union. For this jewel, all forms of diamonds are used. The round brilliant diamond remains the most common choice for wedding rings, but we also make many alliances with diamonds of princess, emerald, heart size ... An alternation of stone shapes is also possible, with for example an alternation round diamonds, baguette diamonds. The combinations are multiple. That said, the brilliant-cut diamond remains by far the most sparkling, so it should be preferred if you are looking for the brilliance of the frame.
 

The diamond pendant

 
It is often offered as a gift at the time of a birth of a girl because it has the advantage of being able to be passed from the mother to the girl (at her 18 years) without worries of setting size. On this occasion, the father usually offers a solitaire diamond pendant. The diamond is then the centerpiece of the pendant, and the mount is the most discreet possible to highlight the brilliance of the stone. Hence the great success of models diamond pendants claws (3 or 4 claws). Timeless and elegant design, this type of frame is great for any type of outfit, especially with tailors.
