Natural Fancy Green and Fancy Light Pink Diamond Halo Ring - 0.423ct Pear Centre, PT950/18K Rose Gold, AGL Thai Certified

PT950 platinum and 18K rose gold. Centre: 0.423ct pear brilliant cut natural Fancy Green diamond, VS1 clarity. Inner halo: 17 round brilliant natural Fancy Light Pink diamonds, 0.08ct TDW. Outer halo and band: 89 round brilliant natural diamonds, F/G colour, SI-I1, 0.54ct TDW. Ring size M. Weight 5.82 grams.



Overview

Natural fancy-coloured diamonds are among the rarest material on earth, and this ring pairs two of the most sought-after colours in a single piece. The 0.423ct pear brilliant centre is a certified natural Fancy Green diamond - a genuinely uncommon colour grade graded by AGL Thai Laboratory (Report #0059359, February 2026). The inner halo surrounds it with 17 natural Fancy Light Pink round brilliants, creating a warm-cool colour contrast that is difficult to replicate. The construction alternates PT950 platinum with 18K rose gold: the centre pear sits in a rose gold three-claw cup that picks up the warmth of the pinks, while the platinum framework provides the contrasting cool backdrop for the outer diamonds.



From the photos, the ring is in new, unworn condition. The hallmark on the inner shank reads "PT950/750 D0.423ct" confirming both metals and centre stone weight. The two-tone construction is clearly visible from the back with the rose gold cup standing out against the platinum framework. The scalloped triple-halo design incorporates open cutaway gallery work underneath for maximum light passage. A recent insurance valuation by a FGAA-qualified appraiser (Karma Gems, April 2026) assessed replacement value at AUD $35,700, confirming new condition and natural fancy colour status.



Note: the outer halo and band diamonds are near-colourless F/G round brilliants, not fancy pink, per the independent valuation. Only the inner 17-stone halo contains the certified Fancy Light Pink stones.
