There are gemstones that simply tell stories and gemstones that silently carry entire traditions. This cushion shaped bi color ametrine of 6.91 carat is one of those rare stones that feels like a relic from an age when fine jewelry marked life passages and stood as family memory. Sourced from Ceylon Sri Lanka and presented by The Natural Gemstone Company, this transparent ametrine measures 11.52 x 11.45 x 7.93 mm and displays a noble balance between amethyst purple and citrine golden yellow. The mixed brilliant cut has been executed to marry scintillation with the soft flooding of color zones, and the excellent polish lets each facet breathe with light. Evaluated at eye level the clarity is very very slightly included, which means the gem reads clean and luminous to the wearer and observer. The color intensity is medium, which gives the piece a graceful presence that reads both subtle and unmistakable depending on light and angle. Heat treatment has been used to enhance the color, a time honored and widely accepted practice in fine gem cutting that stabilizes the tones and reveals the gem as its finest self.
The cushion shape speaks of antiquity, of Victorian and Edwardian jewels that have passed through generations, while the cut and finish reflect contemporary standards of lapidary excellence. The mixed brilliant faceting pattern was chosen to enhance the bi color appeal, so that the pavilion and crown work together to animate the purple and yellow with lively flashes and calm pools of tone. The dimensions lend themselves to a variety of classic settings, from a solitary bezel ring that honors simplicity to a halo surrounded by fine melee diamonds that references royal practice. On the hand the proportions read as bold but balanced, the kind of presence that elevates a wardrobe and anchors a personal collection. The very very slightly included clarity grade is a testament to careful selection, keeping the optical purity high while celebrating the stone as a natural product of the earth. The excellent polish is the final touch of craftsmanship that allows light to play freely across the surface and that will hold its dignity for decades with proper care.
Owning this ametrine is an investment in beauty and in workmanship that transcends passing trends. As a bi color quartz with refined cut and finish, it carries the dual charm of color and clarity in a format that invites both daily wear and ceremonial use. The enduring appeal lies in its provenance, in the hands that shaped it, and in the intention behind its presentation by The Natural Gemstone Company. From the sourcing in Ceylon Sri Lanka, through the heat treatment and then the patient cutting and polishing, each stage adds artisanal value and ensures the gem enters your life as a finished heirloom ready to be set into a design that will be cherished by future generations. For collectors who value the narrative of a stone as much as its optical virtues, this cushion bi color ametrine embodies a continuity of taste and skill that is both investment grade and emotionally resonant. If you are considering a commission or a setting that honors classic lines and lasting elegance, this gem offers a canvas of color and craftsmanship that will reward thoughtful design and long term stewardship.
