Expert Gemmologist and Gemmology graduate, Valerie Danenberg only offers GIA certified diamonds with the certificate number engraved on the bezel (it is the only laboratory recognized worldwide). They are directly sourced on the international diamond market and are purchased without intermediaries. We scrupulously verify that all our diamonds are mined in accordance with ethical conditions that do not contribute to any type of conflict.
The Carat is the international unit of measurement for diamonds. It corresponds to 0.32 grams per carat. The weight of the diamond is one of the major elements because its price also varies according to its weight.
The clarity of a diamond is determined by the nature, location and number of inclusions present in the stone. These inclusions are either tiny crystals (white) or carbon (black) which is the main chemical element that makes up diamonds.
The color of a diamond is determined by the human's expert eye, relative to standards compared under very specific laboratory conditions. It goes from D (the whitest) to Z (the most tinted).
The ideal diamond cut aims to optimize the refraction of light in its facets in order to obtain an optimal brilliance. It is rated on 3 criterias (cut, polish and symmetry) ranging from poor to excellent.
With their discreet and shimmering color, "Champagne" diamonds are timeless. When they are set with a halo of white diamonds it brings out their beautiful color.
The colors are natural and range from lightest to darker brown. Our gemologist carefully select the shades with the most brightness. In contrast to white diamonds, champagne diamonds are not graduated according to the "4C". Purity does not have the same impact on the price, but the gemmologist selects them in minimum purity SI (small inclusions invisible to the naked eye).
We assist you in your choices
The expert eyes and knowledge of our gemologist will guide you in the choice of the diamond that best suits the design you have selected thanks to her perfect comprehension of the "4Cs" and other less known but equally important criterias for an optimal choice.
We always select the best quality
Valerie Danenberg, gemologist and specialist in colored stones, only selects premium quality gems classified as "AAA". Her "stone hunters" travel the world, reserving the most beautiful sapphires, rubies and emeralds for her designs.
THE SHADES OF PRECIOUS STONES
THE "AAA" RATING FOR PRECIOUS STONES
Unlike diamonds, which benefit from a universal and strictly respected rating system, there is no precise rating system for color stones (rubies, emeralds, sapphires). However, not all gems are equal and vary in color, transparency, etc ...
Professionals have therefore set up a scoring system. « A » quality gem is a good quality stone, "AA" quality is for a superior gem, and "AAA" is when the quality of the stone is really exceptional, which refers to the beauty and intensity of the color, the transparency of the stone and finally to its cut. Thus, a transparent stone with a beautiful color but which has been poorly cut can no longer be qualified as "AAA".
Valerie Danenberg is a gemologist and specialist of colored stones. She exclusively selects "AAA" quality stones and guarantees that her stones have not been chemically treated. Thanks to her expertise acquired through internationally recognized experts and by travelling the world in search of the most beautiful stones, she is able to obtain gems of truly exceptional quality. This is particularly the case for her sapphires, rubies and emeralds.
One of the main difficulties of this system is that there is no difference between type I, type II or type III gems. What is a type I gem? It is a gem that is extracted in its natural state without inclusions. Of course, depending on the stone and its origin, inclusions may nevertheless occur, but it is quite common to find specimens that are perfectly transparent. This is the case for example, for citrins, amethysts, tanzanites...
On the other hand, a type III gem almost never presents itself in a pure form. This is the case in particular for emeralds which almost always have inclusions visible to the naked eye.
Consequently, it is difficult to give an "AAA" rating and to compare an emerald with a tanzanite. An "AAA" emerald will have inclusions but will be very beautiful in color and very well cut, a sign of exceptional quality. An "AAA" tanzanite, on the other hand, will be absolutely pure to the naked eye (and also have a superb color and a perfectly executed cut). An "AAA" classification is not a guarantee of a pure stone to the eye, hence it will depend on the nature of the stone.
Our GOLD is guaranteed of superior quality
Yellow Gold : Initially, gold comes from the nuclear fusion reaction of the stars. Yellow gold is the only metal whose natural color remains the same after its extraction. Yellow gold jewelry retains its original brilliance forever.
White gold with Palladium : It is the metal which highlights diamonds the most thanks to its exceptional white color. It is much more resistant than platinum, therefore it does not get scratched up as much and its claws secure the stone for life.
Rosé Gold : Nowadays, it is the most popular precious metal. We make our own alloy whose subtle color comes from the proportion of copper that we include in our alloy, which makes it attractive thanks to the warmth of its color. It is very resistant, hence you can allow yourself to wear it every day as it is difficult to scratch.
Our gold is guaranteed to be of the highest quality, with 0.30 thousandths more fine gold than what is available on the market, for a better quality of casting and more brightness.
The 13% of palladium added to our white gold gives it a better hardness and whiteness compared to the standard 18-carat gold and replaces nickel, which is sometimes allergenic and probably cancerous. This allow is superior to platinum even though it is less costly.
The color of our rosé gold remains the same because it’s copper dosage is studied to avoid oxidation.
Valerie Danenberg comes from the world of Antique jewelry, she has always worked with recycled and traceable gold as it is important to her to create beautiful jewelry while respecting nature.
