ピンクダイヤモンドネックレス

Natural pink diamonds account for less than 0.01% of global diamond production. Their rarity increased dramatically following the closure of the Argyle mine in Western Australia in 2020, which was responsible for the vast majority of the world's supply. With no significant new source to replace it, existing stones are becoming increasingly scarce and sought after.

Pink diamonds are graded by the GIA (Gemological Institute of America) on a scale from Faint through to Fancy Vivid. The more saturated and intense the color, the rarer — and more valuable — the stone. At Weiss, we carry pink diamonds across a wide range of color grades, from accessible Faint Pink stones through to deeply saturated Fancy Pink, so there's an option for different budgets and preferences.

Yes. Every pink diamond at Weiss comes with a GIA or CGL certificate, which independently verifies the stone's color grade, clarity, carat weight, and other key characteristics. This is especially important for pink diamonds given the premium their color commands — certification protects your investment.
