The split bail allows the platinum 850 ball chain to pass through freely, keeping the pendant centered and face-forward on the décolletage at all times. The overall design is intentionally restrained — a platinum frame that recedes completely so the color-change phenomenon of the alexandrite center stone becomes the sole focus of the piece in every lighting condition.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cstrong\u003eAbout the Stone:\u003c\/strong\u003e\u003c\/div\u003e\u003cdiv\u003eThis GIA-certified 0.86 carat oval alexandrite — GIA Report No. 6541806807 — is graded bluish green changing to purple, with transparent clarity and a brilliant crown over step-cut pavilion that optimizes both color saturation and light return simultaneously. GIA's geographic origin determination confirms Brazilian provenance, and the untreated status places this stone among the rarest category of alexandrites available — natural, unheated, with a fully documented color change from bluish green in daylight to purple under incandescent light verified by one of the world's most respected gemological laboratories. Brazilian alexandrite measuring 7.23 x 5.02 x 3.05mm at 0.86 carats with this quality of color change and GIA certification represents a genuinely collector-grade stone — alexandrite with strong, clean color change of this size, from a documented source, with independent laboratory certification is among the most sought-after colored gemstone categories in the fine jewelry market globally.\u003c\/div\u003e","brand":"ASSAY","offers":[{"title":"Default Title","offer_id":47712133480638,"sku":"POTC2647P","price":15000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0508\/5724\/6910\/files\/GIA-Certified-0_86-Carat-Brazilian-Alexandrite-Diamond-Platinum-Drop-Necklace-Necklace.jpg?v=1782338322","url":"https:\/\/assayjewelers.com\/ja\/products\/gia-certified-0-86-carat-brazilian-alexandrite-diamond-platinum-drop-necklace","provider":"ASSAY","version":"1.0","type":"link"}
