Natural Ceylon Alexandrite 1.28ct Modified Cushion Cut

1.28ct Natural Ceylon Alexandrite in a Modified Cushion Cut Discover the understated beauty of this 1.28ct natural Ceylon alexandrite, carefully fashioned into a distinctive modified cushion cut. This rare color-change chrysoberyl combines softly rounded corners with geometric faceting, giving the gemstone an individual shape with an elegant face-up appearance. In cooler daylight, the gemstone presents predominantly soft green tones. Under warmer incandescent lighting, it displays a subtle transition toward muted purplish or brownish hues. Its color change is weak rather than dramatic, making it ideal for clients who appreciate a gentle natural color shift and the individual character of earth-sourced gemstones. With VVS clarity and balanced dimensions of 7.47 × 5.50 mm, this loose alexandrite is an appealing choice for bespoke jewelry, a distinctive engagement ring, a meaningful pendant or a carefully curated colored gemstone collection. Transparent color disclosure: This alexandrite displays a weak and subtle color change. It should not be expected to show the intense green-to-red transformation associated with premium-quality alexandrite. Its appearance will depend on the surrounding light source, viewing angle and environment.

The appearance of this gemstone responds to the spectral qualities of different light sources. Cooler daylight or white lighting emphasizes its green character, while warmer incandescent lighting may reveal muted purplish or brownish secondary tones. Because this particular stone has a weak color change, the transition may be more noticeable when the gemstone is moved directly between separate daylight-equivalent and warm incandescent light sources. Mixed indoor lighting may make the difference appear less obvious. What Could You Create With This Alexandrite? The modified cushion shape offers an individual outline that works beautifully in classic or contemporary jewelry. Its 7.47 × 5.50 mm face-up dimensions may suit: A bespoke alexandrite engagement ring with a natural diamond halo A refined solitaire ring in yellow gold, rose gold, white gold or platinum A three-stone ring with natural diamond or sapphire side stones A meaningful promise ring or anniversary design An elegant alexandrite pendant for everyday or special-occasion wear A rare loose gemstone addition for an alexandrite or colored gemstone collector We recommend asking an experienced jewelry maker to create the setting around the gemstone’s exact measurements rather than relying only on its carat weight.
