Lowest near-colourless grade. Slight warmth visible to a trained eye; still good value for yellow gold settings.
I (Near Colourless): Lowest near-colourless grade. Slight warmth visible to a trained eye; still good value for yellow gold settings.
I is where some viewers begin to detect faint warmth in large stones. In a round brilliant under 1.5ct, I still looks colourless to the unaided eye. In yellow gold, where the metal already brings warmth, I is an efficient grade choice.
Standards bodies: GIA, AGS
Frequently asked questions
Is I colour visibly yellow?
Not in most settings. In a round brilliant under 1.5ct and in any warm metal, I reads as white. In large elongated shapes in white metal, a faint warmth may be visible on careful inspection.
When should I avoid I colour?
When the setting is platinum or white gold and the stone is 2ct+ in an elongated shape. Otherwise I is a fine value choice.
