Quand les diamants de synthèse ont-ils été inventés ?
Title:
Si vous vous demandez depuis combien de temps les diamants de synthèse existent, vous pourriez être surpris par la réponse. Les premiers diamants de synthèse ont été créés en utilisant la technique HPHT (haute pression haute température), et la production a débuté en décembre 1954. Cette méthode reproduit le processus naturel de formation des diamants en laboratoire en nourrissant une minuscule graine de diamant avec des atomes de carbone sous une chaleur et une pression intenses.
Qui a inventé les diamants de synthèse ?
Title:
En 1954, les scientifiques de General Electric à New York ont été les premiers à réussir à créer des diamants de synthèse pour un usage industriel. Au début des années 2000, la technologie des diamants de synthèse avait suffisamment progressé pour que des diamants de qualité joaillerie plus purs puissent être fabriqués en laboratoire. Dès 2010, les diamants de synthèse étaient devenus pratiquement impossibles à distinguer des diamants extraits des mines, si ce n’est par leur origine.
Laboratory Grown Diamonds Step-by-Step
How Long Do Laboratory Grown Diamonds Take to Create?
The length of time it takes for a diamond to form will be determined by its size, but as a guide, a one-carat diamond usually grows in about two weeks using either of the two most commonly used formation processes: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Larger stones may take up to three months to create.
Cut for Brilliance
Swarovski is renowned for its mastery of crystal cutting, and its expertise has been passed through generations of craftspeople since 1895 when founder Daniel Swarovski made the first electric crystal cutting machine. Today, the House only works with laboratory grown diamonds that are precision cut to guarantee the best light performance across all our Swarovski Created Diamonds collections.

The 4Cs Guide of Diamonds
Title:Quality Control
Subtitle:
Universally recognized, the 4Cs are a guiding light in the world of diamonds, helping to determine the quality and value of each stone - the 4Cs stand for color, cut, carat, and clarity. The laboratory grown diamonds in the Galaxy and Eternity collections are graded against these 4Cs by IGI, the International Gemological Institute.

Frequently asked questions
Laboratory Grown Diamonds
How are laboratory grown diamonds made?
Laboratory grown diamonds are crafted using scientific processes. The technology is as brilliant as the diamonds themselves and has evolved over time to be able to create jewel quality diamonds. Each diamond forms in its own unique way.
How long does it take to make a laboratory grown diamond?
The two methods of making diamonds in a laboratory work at similar speeds. One is Chemical Vapor Deposition (CVD) and the other is High Pressure High Temperature (HPHT). The size of diamond being grown will determine the time it takes, but as a guide, a one-carat diamond grows in about two weeks. Larger stones may take up to three months to complete.
How long does it take a diamond to form naturally?
Natural diamonds take millions of years to form deep within the earth's mantle under extreme heat and pressure, conditions that are recreated scientifically in a laboratory to grow man-made diamonds in weeks.
