The AG & CO Difference: Diamonds That Truly Sparkle
✨💎
A diamond can score well on certification but still be dull, hazy, and lifeless. IGI/GIA reports focus on technical grading but don’t include critical visual factors that directly impact appearance, brilliance, and value of the diamond.
At AG & CO Jewellery every diamond is carefully screened & evaluated by our expert gemmologists for:
Luster/Brilliance - The quality of light reflection on the diamonds surface, which creates its sparkle.
Eye-Cleanliness - Whether inclusions or blemishes are visible to the naked eye.
Presence of Brown, Green, or Milky Hues (BGM) - Shades/undertones of Brown, Green/Grey, & milky/cloudy appearance that can dull a diamonds brilliance and sparkle.
A highly graded diamond on paper doesn't guarantee it will be visually beautiful in person. Unfortunately, some jewellers sell lower-quality diamonds at premium prices without disclosing flaws like poor luster or BGM.
