When Were Laboratory Grown Diamonds Invented?
Title:
If you’re wondering how long laboratory grown diamonds have been around, you may be surprised by the answer. The first man-made diamonds were crafted using the High Pressure High Temperature (HPHT) technique, with production starting in December 1954. This method replicates the natural diamond formation process in a laboratory by nurturing a tiny diamond seed with carbon atoms under intense heat and pressure.
Who First Invented Laboratory Grown Diamonds?
Title:
Scientists at General Electric in New York were the first people to successfully create laboratory grown diamonds for industrial use in 1954. By the early 2000s, laboratory diamond technology had advanced enough that clearer, gem quality diamonds could be made in labs. By 2010, diamonds were consistently being produced that were indistinguishable from mined varieties in every way but origin.
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.

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.

Guide des 4C du diamant
Title:Contrôle de la qualité
Legenda:
Reconnus dans le monde entier, les 4C sont une référence dans le monde diamantaire pour évaluer la qualité et la valeur d’une pierre, selon quatre critères : la taille (cut), la clarté (clarity), la couleur (color) et le caratage (carat). Les diamants de synthèse des collections Galaxy et Eternity sont également évalués en fonction des 4C par l’IGI (International Gemological Institute).
