  • 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.

  • Diamond Authenticity & Certification 

    At AG & CO Jewellery, every diamond is certified by IGI or GIA (unless stated otherwise), but we go beyond paperwork. Our expert gemologists meticulously screen and evaluate each diamond to ensure it meets our strict quality standards for brilliance and beauty.

    Our Quality Promise:

    Exceptional Luster & Brilliance – We select only diamonds with superior light reflection for maximum sparkle.

    BGM-Free Diamonds – No brown, green, or milky hues that can dull the stone’s brilliance.

    100% Eye-Clean – Each diamond is carefully inspected to ensure no visible inclusions or blemishes.

    Minimal to No Bow-Tie Effect – For diamonds where this applies, we assess and select only those with optimal light performance.


    When you choose an AG & CO diamond, you’re getting more than certification—you’re getting a truly radiant and flawless diamond.
