This truly breathtaking natural Alexandrite & diamond platinum ring displays an extraordinary, optical phenomenon: it shifts color from a deep teal-green in daylight to a warm fuchsia pink in candlelight. Set with a stunning heart cut Alexandrite and six round brilliant cut diamonds, this is a one-of-a-kind ring that will never be repeated. 

Natural, sharp color-changing Alexandrites are among the rarest collector items on earth. Contemporary jewellery designer Christine Sadler sourced and hand-selected this rare gemstone directly from an expert gemologist, who verified its origin as the legendary riverbeds of Tunduru, Tanzania. 

Inspired by our signature Hearts On Fire design silhouette, this unique ring is sculpted to represent a profound, passionate love story:

  • The Band: The fluid platinum band curves like the energetic spark of a first connection, radiating outward in waves of heat.
  • The Claws: Each delicate claw is shaped into miniature flames, symbolizing the power of a love that lights up your life.
  • The Heart: The center heart-cut stone sparkles alongside six round brilliant-cut diamonds, creating a fire that will never go out.

View in Scotland or Secure Online Ordering

As this is a completely unique 1-of-1 piece, we invite you to view its color-shifting properties in person or secure it online with total peace of mind.

  • In-Studio Viewing: Arrange a private appointment at our Ayr, Scotland studio to view the stone under different lighting environments.
  • Secure UK Delivery: Includes complimentary, fully insured, secure UK next-day delivery.

Note on Custom Sizes: If you require a different finger size, this exact Alexandrite gemstone will be unset and a brand-new bespoke platinum band in your chosen size will be made within six to eight weeks.
