custom made jewelry –Precious stones
It is very common to use gemstones on silver jewelry to create beautiful pieces of jewelry with originality because of the patterns and color of the stone. Few stones are alike, and so these jewels with natural stones are almost unique. We invite you to discover the immensity of the variety of fine stones, and much more.
Tanzanite stone is not a precious stone, within the meaning of French law, which only considers diamonds, sapphires, rubies and emeralds as such.
However, the price of Tanzanite stone makes it a gemstone in its own right :
- it is rare in geological sense (1000 times rarer than diamond)
- it has exceptional blue / violet colors
- it is in great demand in jewelry
- we are already talking about the closing date of the only production mine
To better understand the fascinating history of this stone, we invite you to dive into the origins of its discovery.
At the beginning, synthetic diamonds were primarily intended for industry. With technological advances of recent years their quality now equals natural gemstones, to the point that it's impossible to distinguish them with the naked eye.
But the arrival of synthetic diamonds on the jewelry market is a threat for Africa, which is largely absent in this developing market.
Since its discovery, diamond has fascinated men.
While the origin of its exploitation dates back to 3000 years in India, it is its exceptional hardness that first made it famous and pushed men to confer magical powers, using it as an amulet carried in the form of raw diamond.
While today diamond is best known for its brilliance, it wasn't until the mid-fourteenth century before diamond cutting techniques developed.
Previously, diamonds worn in jewelry had an opaque diamond appearance like the one shown in the following photo.
Whether you're looking for a diamond to mount it on a ring, a jewel or invest, you're certainly wondering :

Purity, also called clarity of diamond, is with its color a criterion difficult to appreciate for non gemologists.
This is a comparative classification criterion for diamonds based on the number and size of inclusions (various impurities) present at the heart of the crystal and surface defects of the gemstone. This is one of the 4 criteria for assessing white diamonds quality.
The purity index is evaluated by a gemologist with a magnifying glass x10, analyzing diamond under a cold light (typically LED) held by tweezers on a white background.
Blue diamond may be a diamond, the rarity of its color in nature makes it a gemstone much more expensive than the classic white diamonds. This explains why blue diamonds regularly make headlines, each time beating price records at auctions.
It owes its color to the presence of Bore at the heart of its structure, therefore requiring particular geophysical conditions for its formation. This explains why only three mines in the world produce most of the production of natural blue diamonds:
- Argyle Mine in Australia
- Culligan Mine in South Africa
- Golonconda Mine in India
Black diamond is also called Carbonado.
Black diamonds are much older than white diamonds or colored diamonds on earth, but their discovery is recent since it dates from the mid-nineteenth century (find out more) and the interest of the public and jewelers is even more.
First black diamonds were used in jewelry in the twentieth century only and it's only very recently that they have really started to gain value in the gemstone market.
Pink diamonds are the rarest diamonds of all colored diamonds. It is estimated that only one diamond per 100,000 extracts can be classified as pink.
And only a handful of these can be classified as Fancy Intense or Fancy Vivid. This and the craze of collectors and celebrities for pink stone explains that pink diamond prices have soared recently to beat all records at auctions.
Although yellow diamond is less used in jewelry than pink diamonds (fr) or blue diamonds (fr), they are however much more present in nature than the latter.
Yellow diamond is indeed the most common of all colored diamonds. It owes its hue to the presence of nitrogen atoms in its crystalline structure.
The authenticity certificate of diamond is an official document issued by an independent laboratory that guarantees the quality of the diamond you plan to buy.
The certificate is issued by an independent body of your diamond dealer. It guarantees the characteristics of the diamond that is presented to you, which characteristics justify the price of the diamond.
The physicochemical composition of the diamond makes it possesses particular optical properties, which with its hardness have helped to make it an exceptional precious stone and certainly the most coveted until today.
Possessing a high index of refraction and a strong dispersive power, the diamond sharply diverts the light penetrating it and disperses this light in a rainbow of color as do drops of water to produce the rainbows in the sky.
Anyone looking to buy a beautiful diamond or a jewel set with diamonds of respectable size (0.2 carat) must understand the quality scale applied to diamond in order to classify and estimate their value.
The 4Cs of Diamond for Carat (weight), Color, Clarity (purity) and Cut is an international classification rule valid for all white diamonds.
All jewelers, diamond dealers and gemologists refer to it to understand each other when comparing the quality and price of diamonds.
And so, it's your turn to understand the 4Cs of diamond to choose the best your diamonds.
