Our diamonds
At AUCLAIRE, each stone is chosen with exacting standards.
We work exclusively with lab-grown diamonds of VVS1 quality, D color, all certified by GIA, the most recognized international standard in jewelry .
What is a laboratory diamond?
Un diamant de laboratoire est un véritable diamant, créé par l’homme dans des conditions qui reproduisent fidèlement celles de la nature.
Il possède la même structure cristalline, la même dureté, la même brillance et la même composition chimique qu’un diamant extrait de mine.
La seule différence réside dans son origine :
-
le diamant naturel se forme sous terre pendant des millions d’années
-
le diamant de laboratoire est cultivé en quelques semaines
À l’œil nu, ils sont strictement indiscernables. Même un gemmologue a besoin d’équipements spécialisés pour les différencier.
How are our diamonds made?
Our diamonds are created using high-tech processes that replicate the extreme conditions of nature (pressure, temperature, pure carbon).
The crystal develops layer by layer until it forms a stone with properties identical to a natural diamond.
Each diamond is then:
precisely cut
analyzed according to the 4C criteria (Carat, Cut, Color, Clarity)
individually certified by the GIA
Only VVS1 Color D
At AUCLAIRE, no compromise is made on quality.
The result: diamonds of exceptional purity, with a clear, cool and perfectly controlled brilliance.
VVS1
microscopic inclusions, invisible even under magnification
Color D
the highest existing grade of whiteness
Size of excellence
for maximum shine
