5.19 Ct. Ametrine from Ceylon (Sri Lanka)

If you have been searching for a single gemstone that answers the call for rarity, beauty, and versatility, this transparent 5.19 carat emerald cut bi color ametrine from The Natural Gemstone Company will end that search, its graceful proportions and unique color story offering a ready solution for collectors and bridal customers alike. Measuring 14.58 x 7.48 x 6.69 millimeters, and cut in a classic emerald shape, this stone presents a long elegant table and step facets that emphasize clarity and color separation, the medium color intensity of the purple and golden yellow zones showing with even saturation and pleasing balance. Evaluated at eye level as very very slightly included, and finished with an excellent polish, the gem reads as clean and luminous, large enough to command presence on a ring, pendant, or bespoke piece, while still being comfortable for everyday wear. Heat treated to enhance stability and color harmony, and sourced from Ceylon Sri Lanka, this ametrine combines trustworthy provenance with the kind of visual drama that collectors seek and couples want as a signature engagement statement.

When people talk about brilliance they often mean the intense white light return and scintillation that diamonds are famous for, and by that measure diamonds will always retain an advantage due to their higher refractive index and strong dispersion. That said, brilliance is only one aspect of gemstone beauty, and this ametrine excels at the visual effects that matter when you are looking for something truly distinct. Compared to common colored stones such as amethyst or citrine, which show a single tone, this bi color ametrine offers two complementary palettes in a single crystal, so it creates an immediate contrast and depth that single tone gems cannot replicate. Against sapphires and emeralds, which deliver saturated color and a rich, jewel like depth, this ametrine trades pure saturation for a dynamic color field that shifts with viewing angle and light source, producing broad flashes of yellow and purple rather than the pinpoint sparkle of a diamond. The emerald cut further amplifies these attributes, its long step facets acting like parallel mirrors that emphasize the clean planes of color, so when light moves across the stone you see elegant bands of color and a sophisticated glow rather than busy scintillation. The excellent polish maximizes light flow through the gem, and the very very slightly included clarity grade means those color bands are seen without distraction, producing a refined and modern kind of brilliance that stands out by virtue of rarity and compositional harmony.

If your goal is an engagement ring that tells a different story, or a standout addition to a gemstone collection that will invite questions and admiration, this 5.19 carat Ceylon ametrine is a perfect solution, its size and clarity making it especially suited to a solitaire or three stone setting where the bi color nature can be showcased. At The Natural Gemstone Company we understand that buyers want both beauty and confidence, so we present this gem with full disclosure of its heat treatment and origin, and with close attention to how it will perform in wearable form, the emerald cut offering predictable siting in a bezel or four prong mounting that protects the corners while allowing the long table to display its color zones. For collectors seeking a specimen with museum quality appearance, this ametrine offers provenance and visual drama that is uncommon in quartz family gems, and for those planning a bespoke engagement piece it allows a wearable statement that is both romantic and unmistakably singular. If you are ready to make this gem the centerpiece of your next design, we will be pleased to discuss mounting options and to ensure the gem is shown to best advantage, because when the search is for something unforgettable, this ametrine completes the quest.
