Natural Vibrant Pink Spinel | 0.45 Carat Oval Cut Loose Gemstone
Bring an undeniable spark of romance and luxury to your designs with this breathtaking Natural Vibrant Pink Spinel. Boasting a larger, eye-catching 0.45 carat weight, this gem features an electric, hot-pink saturation that practically glows against its lush green background.
Perfectly faceted into a classic oval cut, its brilliant sparkle and rich magenta-pink tones make it an exceptional center stone for bespoke jewelry.
