Frequently Asked Questions
Diamonds
Éternel selects diamonds that are used to set its creations according to the universal certification established by the GIA (Gemological Institute of America) and based around 4 criteria known as the 4Cs: « Colour », « Clarity », « Cut » and « Carat weight ».
COLOUR
The GIA evaluation uses a colour scale ranging from D (perfectly white diamond) to Z (slightly yellow-tinted diamond).
Éternel only selects perfectly white, colourless diamonds between D and G for its creations.
CLARITY
The GIA’s clarity scale classifies diamonds from FL (« Flawless – a diamond without a single flaw ») to I3 (« Included’ – diamonds with inclusions that are visible to the naked eye). Only diamonds from categories FL to VS (« Very slightly included – diamonds with only very slight inclusions ») are selected for the Eternel's creations. Éternel diamonds do not have any inclusions that are visible to the naked eye.
Each stone is unique and characterised by its degree of clarity, which is determined by the number, size and position of the inclusions. These imperfections are marks left by nature during the diamond’s formation. The inclusions are recorded and mapped on the GIA diamond certificate and AGS Ideal Certificate (Only with diamonds over 1 ct)
CUT
The cut of a diamond finds the balance between proportions and angles in order to achieve optimum brilliance. A very precise cut allows the stone to catch the light and reflect it through its facets, reflecting the brilliance and sparkle back to the eye of the beholder.
The quality of the cut is determined using a scale ranging from « Excellent » to « Poor ». Éternel only selects diamonds of a high quality, either « Excellent » or « Very Good » diamonds.
Éternel by Carranza y Carranza goes beyond the current market of lab-grown diamonds with our remarkable Original Ideal Cut®. The quality of our diamonds' cut are of the highest quality possible to achieve the most light reflection and beauty of the diamond. All of Éternel diamonds come with a GIA Report and a AGS (American Gem Society) Ideal Report, which maps and documents the individual diamond´s unique specifications, Light Refraction Index and Symmetry Report.
CARAT
A carat is a unit of measurement for the weight of a diamond. 1 carat is the equivalent of 0.20 grams, or 5 carats to 1 gram. Combined with the other three « Cs », the weight determines the value of a diamond. The heavier the weight, the more valuable and rarer it is.
Éternel offers diamonds of all sizes and weights in a wide range of settings.
