GIA-certified 0.86 carat oval cut natural untreated Brazilian alexandrite and 0.23 carat tapered baguette diamond solitaire drop pendant in platinum 900, featuring a transparent color-change alexandrite graded bluish green to purple by GIA in a four-prong setting below a tapered baguette diamond accent, suspended on a platinum 850 ball chain.

Total weight 3.63 grams; GIA Report No. 6541806807; chain included.

The pendant is constructed in platinum 900 as a clean, minimalist vertical solitaire — the GIA-certified oval alexandrite sits in a four-prong basket at the base, connected by a slim platinum stem to a tapered baguette diamond accent positioned between the split bail above. 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.

This 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.
