KOKO Diamonds by KT Jewellery

Established by KT Jewellery founder Mr Koko Tchorbadjian, KOKO Diamonds is the culmination of his life’s work and dedication to the Perfect Diamond.

Mr Tchorbadjian, our head master goldsmith, craftsman and designer has over 40 years’ experience in the jewellery trade being a second generation jeweller. His ethos is to most importantly capture the brilliance of a diamond through meticulously crafting our exceptional pieces to the highest standards in our own workshop at our Glen Waverley boutique.

Mr Tchorbadjian works closely with our exclusive diamond merchants located in the heart of the world’s finest diamonds, Antwerp, Belgium, to personally select and pass onto our clients only the finest of diamonds for their bespoke pieces.

KOKO Diamonds’ attributes are more than just the 4C’s (Colour, Clarity, Cut, Carat). Having to be visually independently selected, what is most important is the timeless beauty of the stone and Mr Tchorbadjian’s unsurpassed skill in capturing this beauty and brilliance in the perfect piece.

All KOKO Diamonds engagement rings are independently certified by the GIA (Gemological Institute of America) and IGI (International Gemological Institute), two of the world’s leading diamond and gemstone grading laboratories. These KOKO Diamonds range in Colour from “D” being the highest and most colourless/whitest grade of diamonds to “H” a midrange of near colourless grade. As for Clarity, KOKO Diamonds range from the highest grading of “Flawless” to “Si2” which has the slightest of inclusions not noticeable to the naked eye but only visible under 10x magnification.

Select KT Jewellery Signature diamond pieces, including rings, earrings, pendants and bracelets have been individually hand selected to meet Mr Tchorbadjian’s exacting KOKO Diamonds standards and are furnished with the whitest and cleanest of diamonds.

All KOKO Diamonds engagement rings and selected KT Jewellery Signature pieces are provided with an independent valuation and lifetime warranty consisting of cleaning, polishing and rhodium plating. Regular inspection of all items is highly recommended to ensure the security of set stones and no accidental damage from everyday wear.
