FREQUENT QUESTIONS

#01. General questions

DFLY is a jeweler from the 21st century. The firm has been created by two complementary talents coming both from gemology and high tech sport. This association stimulates contemporary and comfortable creations always more respectful of human beings and the planet. On top of using lab grown diamonds and recycled gold, DFLY elevates the value of all its pieces of jewelry under the skill and expertise of the French craftmanship. DFLY is the shared experience of professional certified gemologists teamed up with an acute eye on style, environment and technological trends of our time. 

Each and every of these three terms describe the exact same diamond which is duly considered as a diamond, just like the mine diamond is, carrying strictly the same physical, chemical and optical properties according to the independent international institutes (e.g. HRD, GIA, IGI). In France, the arrival of a gem quality lab grown diamond on the open market happened later to the law defining the gem appellations, decree  #2002-65 dated January 14th , 2002. According to article 4, this legal norm imposes the appellation “synthetic diamond” or “synthesis diamond”. It is a bit misleading as the term “synthesis” implies many components which is here not the case as the diamond is solely composed of one single element, (the) carbon. The FTC (Federal Trade Center) in the US has therefore taken out both the term “synthetic” for the man-made diamond and the term “natural” for the geological diamond. A diamond is a diamond regardless of its origin.

#02. JEWELRY & GEMS

A.THE JEWELS

All gold or platinum jewels made in France are stamped with an assay mark. DFLY uses only precious metals with alloy of high standard purity. Thus, the 18 k (750/1000) is stamped with an eagle’s head mark and 950/1000 platinum is stamped with a dog’s head mark . Only small jewels weighing less than 3 g can be exempt from theses hallmarks (like the stud earrings.)  

The jewels made of precious metals manufactured in France are stamped with a diamond-shaped mark called “poinçon de Maître” (Maker’s mark) or “Poinçon d’atelier” (workshop’s mark) Each diamond-shaped marks engraved with the initials and/or symbol of the makers. 

An authenticity certificate is delivered with each DFLY jewel. It is the guarantee of an original DFLY piece of jewelry as well as the respect of the DFLY quality norms such as the fabrication, the finish, the selection and the quality of the used materials. Whenever possible, each jewel carries a printed signature as well as an identification number.

If you don’t know your finger size or your wrist size, DFLY proposes you appropriate ways to measure. On each product page of this site, a size guide allows you to identify your correct sizes.

B. THE GEMS

A lab grown diamond is identical to a mine diamond, it is a diamond; it carries the exact same optical, chemical, physical characteristics, and each stone is unique.

  1. The lab grown diamond respects human beings and nature
  2. The lab grown diamond is especially pure and of good quality (often type II2, those diamonds represent only 2% of the mine diamonds)
  3. Its price is controlled which allows the purchase of a bigger stone (or gem) 

A lab grown diamond is more respectful of the environment because it doesn’t necessitate the digging of the biggest holes ever created by humans, it doesn’t destroy the seabed and the biodiversity. It also frees itself from any human exploitation.

A lab grown diamond is free of any cartel, has much less intermediaries than the mine diamond. The production circuit of the lab grown diamond is short and thus allows a better control of the costs and finally gives a better pricing for the final consumer, you.

DFLY team is made up of professional gemologists, specialized in the diamond grading and appraisal. They will be delighted to introduce you to the discovery of the lab grown diamond and will guide you in the choice of the right best stone for you. By video conference, by phone, or by appointment at the showroom

A laboratory certificate is the scientific grading report of the unique characteristics of each lab grown diamond (the 4 Cs : Carat - Clarity - Color - Cut) issued by independent and worldwide known gemological laboratories 

DFLY is proud of selling lab grown diamonds and pushes for a truly identified market. All our lab grown diamonds (above 0.30 carat) are delivered with their specific gemological grading report that includes the unique micro-laser number engraved on the girdle of the diamond.  

A universal convention determines the quality of a diamond: 

Carat: The carat is the weight unit of the precious stones, 1 carat means 0,2 grams.

Color: The color of the diamond is graded on a scale from D (colorless) to Z (yellow to brown colors). The colorless diamonds being the most precious ones. The diamonds with pink, blue, red…colors are called “Fancy Colors” and are graded from Faint to Fancy Dark.

Clarity: The purity, each stone develops more or less internal and external inclusions during its growth. Often invisible to the human eye, these characteristics are graded on a scale starting from IF (Internally Flawless) to I3 (Included 3).

Cut: The Cut is the sole quality of the 4Cs that only relies on the human eye, three criteria come into play: the polish, the symmetry and the proportions of the stone. DFLY invites you to check our Lab grown diamond page where you will find additional information.

DFLY proposes only lab grown diamonds with a color graded from D to H and a clarity from IF to VS
