Cut — The Most Important C
Cut determines how a diamond interacts with light. A well-cut diamond returns light directly to the eye as brilliance (white light), fire (spectral colour), and scintillation (the pattern of bright and dark areas). ReAurra sources only Excellent and Ideal-cut stones. A poorly cut diamond of high colour and clarity will appear dull; a well-cut stone of modest grade will sing.
Colour — The Subtlest C
The GIA colour scale runs from D (colourless) to Z (light yellow). The difference between adjacent grades is invisible to the untrained eye, but cumulatively significant. ReAurra works within the D–H range — the window in which colour is imperceptible in a face-up stone. Beyond H, warmth becomes visible in larger stones.
Clarity — The Most Misunderstood C
Clarity grades the presence of inclusions (internal) and blemishes (surface). The GIA scale runs from Flawless (FL) to Included (I3). ReAurra sources VS2 and above — at VS2, inclusions are not visible to the naked eye under any reasonable viewing condition. Paying premium prices for IF or FL clarity is rarely justified in stones under five carats.
Carat — The Most Visible C
Carat is a unit of weight (0.2 grams), not size. Two diamonds of the same carat weight can appear very different in size depending on their cut proportions. A deeply cut diamond hides weight in its pavilion; a well-cut stone of the same weight will appear larger. Always assess a diamond in person before purchasing on carat weight alone.
The Fifth C — Certificate
Every ReAurra diamond above 0.5ct is accompanied by a GIA, GRS, or Gübelin certificate. These independent laboratories are the only authorities whose grades we accept without question. A certificate from an unknown or house grading laboratory is worth precisely nothing as a resale document.
