PHENOMENAL GEMSTONES
Sri Lankan Alexandrite Ring
Introducing a captivating 4.24ct Masterpiece Alexandrite, this unique stone is prized for its colour changing properties and often described as Emerald by day, Ruby by night.
A Global Quest
Alexandrite’s Origins
The Ural Mountains are historically a source of fine Alexandrite, with the first abundant deposits being discovered in 1830. These mines produced high-quality stones renowned for their vibrant hues and dramatic colour change. These remarkable deposits were exhausted by the turn of the 20th century, further increasing the scarcity of this highly prized phenomenal gem. Today, Alexandrite is sourced from variety of small specialist mines across the globe, including ones in East Africa, Brazil and Sri Lanka where particularly fine examples such as this one are found.
The Gem Chameleon
Emerald by Day, Ruby by Night
Alexandrite is famed for its extraordinary ability to transform colour under various lighting conditions, also known as photochromism. Often described as “Emerald by day, Ruby by night,” these gemstones contain chromium and beryllium enabling them to exhibit the highly prized colour change effect. In natural sunlight, Alexandrite shimmers with vibrant forest green hues, while candlelight reveals a deep red shade. This is a particularly exceptional example due to its size (4.24ct), clarity and the intensity of colour change making it a truly phenomenal gemstone sought after by gem enthusiasts worldwide.
Crafting for Colour Change
A Perfect Union
Our Manhattan setting was selected to showcase the exceptional central stone. Set in between ribbons of white diamonds and platinum, the central stone is perfectly paired regardless of the Alexandrite’s Emerald green or Ruby red hues. The panoramic display of gems in the rings shoulders is achieved through the collaboration of the stone setter and cutter, who work in unison to create perfectly paired sets of tapered stones, seamlessly set into the graduated ribbons, wrapping around the platinum band.
A Phenomenal Showcase
Nature's Magic
The final piece demonstrates the most skilful of designs, beauty in simplicity. The colour change is a phenomena so extraordinary it has to be seen to be believed. This particularly fine example exhibits an exceptionally strong change between its natural forest green Emerald hues (under daylight) and a deep Ruby red (when introduced to candlelight). Pragnell Masterpieces carry the numbers 5 & 6 to reflect that all our Masterpieces are designed in numbers 5 and 6 Wood Street, the home of Pragnell.
