{"title":"Teal Sapphire Over 1 Carat - Unheated Natural Loose Stones","description":"\u003ch2\u003eNatural Teal Sapphire Over 1 Carat — Unheated Loose Stones, Ceylon and Madagascar\u003c\/h2\u003e\n\n\u003cp\u003eTeal sapphire above 1 carat is the defining stone of the current decade in coloured gemstones. No colour in natural corundum has attracted more interest from custom jewellers, non-traditional engagement ring buyers, and collectors over the past five years — and for good reason. Teal sapphire sits at the precise intersection of blue and green where no other gemstone category operates at this quality level: it is as hard as blue sapphire (Mohs 9), as colour-rich as the finest Montana sapphire, and — critically — almost universally unheated, meaning you receive a natural-colour stone with no thermal enhancement in a size and price range that remains more accessible than equivalent blue. Every stone in this collection is natural corundum, completely unheated, photographed under standardised lighting, and sold with full disclosure.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Teal Sapphire Actually Is\u003c\/h2\u003e\n\n\u003cp\u003eTeal sapphire is not a marketing invention — it is a specific colour position in the blue-green corundum family. Natural corundum coloured by iron and titanium can produce a range of blue-green hues depending on the exact ratio of those elements and the crystal growth conditions. The teal zone sits where blue and green are approximately equal in visual weight — neither clearly blue nor clearly green, but distinctly both.\u003c\/p\u003e\n\n\u003cp\u003eWithin the teal family you will see several hue descriptions used across this collection. \u003cstrong\u003eTeal\u003c\/strong\u003e proper — a balanced blue-green with equal weight on both sides. \u003cstrong\u003eBluish-green\u003c\/strong\u003e — teal with a slight blue dominance, appearing more blue in daylight and more balanced under tungsten. \u003cstrong\u003eTeal-green\u003c\/strong\u003e — teal with a slight green dominance, appearing more vivid green in natural light. \u003cstrong\u003ePeacock teal\u003c\/strong\u003e — the most prized position, described as the deep, saturated blue-green of peacock feathers, with extraordinary colour shift between daylight and incandescent light. Every listing describes the specific hue of that individual stone accurately.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Over 1 Carat Is Where Teal Sapphire Becomes Serious\u003c\/h2\u003e\n\n\u003cp\u003eSub-1-carat teal sapphire is beautiful and accessible. Above 1 carat, the category changes meaningfully. Fine-colour teal sapphire rough large enough to yield a 1ct+ finished stone in good clarity is not abundant — teal rough competes with blue rough at the source, and fine material is increasingly sought by cutters who understand the demand. The 1-carat threshold is also where teal sapphire shifts from accent stone to centre stone territory, and where individual stone character — exact hue position, colour shift behaviour, clarity, and cut quality — drives value more than weight alone.\u003c\/p\u003e\n\n\u003cp\u003eAt 2ct+, GIA documentation becomes the standard expectation, as it does in any coloured gemstone at this price tier. Two of the stones in this collection carry GIA reports confirming species, treatment status, and colour. Every stone is sold with complete treatment disclosure.\u003c\/p\u003e\n\n\u003ch2\u003eTeal Sapphire and Heat Treatment — Why Almost All Are Unheated\u003c\/h2\u003e\n\n\u003cp\u003eTeal sapphire is one of the very few sapphire colours where heat treatment is genuinely uncommon rather than the default. The teal colour in natural corundum sits in a colour zone that heat tends to push toward blue rather than enhance — heating a teal sapphire often destroys the green component that makes it valuable. The commercial result is that most fine teal sapphires on the market are unheated by commercial necessity, not just by selection. Every stone in this collection is completely unheated, confirmed by independent assessment and disclosed explicitly on the product listing.\u003c\/p\u003e\n\n\u003cp\u003eFor buyers who value natural-colour gemstones — whether for collection, investment, Jyotish, or simply the knowledge that the colour is exactly as nature produced it — teal sapphire is one of the most accessible categories where unheated is the rule rather than the exception. See our \u003ca href=\"\/en-hk\/pages\/heated-vs-unheated\"\u003eheated vs unheated guide\u003c\/a\u003e for full detail on what this means for value and durability.\u003c\/p\u003e\n\n\u003ch2\u003eCuts in This Collection\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eCushion cut\u003c\/strong\u003e is the dominant format for teal sapphire — the cushion geometry concentrates the blue-green across the face while retaining maximum rough weight. Most commercial teal sapphire above 1 carat is cut cushion for this reason. \u003cstrong\u003eRound cut\u003c\/strong\u003e is rare in teal sapphire — round cutting requires significantly more rough for the same finished weight, making round teal sapphires meaningfully scarcer than cushion or oval at equivalent quality. Both round stones in this collection represent a genuine cut premium. \u003cstrong\u003eEmerald cut\u003c\/strong\u003e (step cut) is the most architecturally striking format — the long open facets of a step-cut teal reveal the colour in a window-like display rather than the sparkle of a brilliant cut, producing a different and equally compelling aesthetic. Emerald-cut teal sapphire above 1ct is very unusual. \u003cstrong\u003eOctagon cut\u003c\/strong\u003e sits between emerald and cushion — a hybrid that combines step-cut clarity with a softer outline. \u003cstrong\u003eMatched pairs\u003c\/strong\u003e — the 1.50ctw oval pair in this collection is specifically calibrated for three-stone ring use.\u003c\/p\u003e\n\n\u003ch2\u003eTeal Sapphire Over 1 Carat for Engagement Rings\u003c\/h2\u003e\n\n\u003cp\u003eTeal sapphire is the leading non-traditional engagement ring stone of the current decade. Above 1 carat, it makes a commanding centre stone with a colour that is immediately distinctive and unlike anything available in the standard jewellery market. A 1ct cushion teal sapphire measures approximately 6.5mm across — a proportionate and wearable size for a solitaire. A 1.75ct cushion runs approximately 7.5mm — a strong statement size. The 2ct+ stones in this collection, in round and emerald cuts, are serious centre stones that will read as bold engagement jewellery on any hand size.\u003c\/p\u003e\n\n\u003cp\u003eTeal sapphire pairs exceptionally well with yellow gold (which creates a rich complementary contrast), rose gold (which warms the blue-green), and white gold or platinum (which maximises the cool, peacock character of the colour).

Current market reference points for natural unheated teal sapphire above 1 carat: \u003cstrong\u003e1.0–1.5ct, unheated, good colour, cushion or oval:\u003c\/strong\u003e $700–$1,400 total. \u003cstrong\u003e1.5–2.0ct, unheated, vivid colour, cushion:\u003c\/strong\u003e $1,400–$2,500 total. \u003cstrong\u003e2ct+, unheated, vivid colour, GIA:\u003c\/strong\u003e $2,500–$5,000+ depending on colour position, cut, and clarity. Round and emerald cuts at any weight command a premium over cushion for cut rarity. Every listing in this collection shows the total price and the price per carat for direct comparison.\u003c\/p\u003e\n\n\u003ch2\u003eCollector and Investment Considerations\u003c\/h2\u003e\n\n\u003cp\u003eNatural unheated teal sapphire above 1.5 carats in vivid colour with strong colour shift is genuinely scarce relative to current demand. The supply from Sri Lanka, Madagascar, and Africa is not keeping pace with buyer interest — custom jewellers who built their reputations on teal sapphire are now competing with collectors and institutional buyers for the same fine material. For buyers considering teal sapphire as a long-hold collector piece, the 2ct+ unheated GIA stones in this collection represent the quality tier where appreciation is most historically supported.

It scores 9 on the Mohs hardness scale, identical to blue sapphire, making it entirely suitable for daily-wear jewellery. The colour is predominantly natural and unheated, which is unusual among sapphire colours where heat treatment is the commercial standard.\u003c\/p\u003e\n\n\u003ch3\u003eHow much does a 1 carat teal sapphire cost?\u003c\/h3\u003e\n\u003cp\u003eA natural unheated teal sapphire at 1 carat in good colour typically ranges from $700 to $1,400 total depending on hue position, saturation, clarity, and cut. Cushion cuts at this weight are the most common format. Round cuts command a premium for cut rarity. Vivid peacock-position stones sit toward the upper end of the range. Every listing shows price per carat alongside total price for easy comparison.\u003c\/p\u003e\n\n\u003ch3\u003eIs teal sapphire always unheated?\u003c\/h3\u003e\n\u003cp\u003eThe vast majority of commercial teal sapphire is unheated because heat treatment tends to push the colour toward blue, eliminating the green component that defines the teal hue. As a result, unheated is the norm rather than the exception in this colour category. Every stone in this collection is confirmed unheated and disclosed as such on its product listing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between teal sapphire and Montana sapphire?\u003c\/h3\u003e\n\u003cp\u003eMontana sapphire is a specific geographic origin — sapphire mined in Montana, USA, which produces blue-green stones in a similar colour space to teal. Ceylon and Madagascar teal sapphire are different origins producing overlapping but not identical colour ranges. Montana sapphires carry a strong American-origin premium and are typically in the sub-1ct range commercially. The stones in this collection are from Sri Lanka and Madagascar — different origins, similar colour family, typically larger sizes and more accessible pricing.\u003c\/p\u003e\n\n\u003ch3\u003eIs a 1ct+ teal sapphire good for an engagement ring?\u003c\/h3\u003e\n\u003cp\u003eYes — teal sapphire is the most sought-after non-traditional engagement ring stone currently on the market. Its Mohs 9 hardness makes it the most durable coloured gemstone option for daily wear. Above 1 carat, it makes a distinctive, commanding centre stone. A 1.3ct cushion measures approximately 7mm across — proportionate for most hand sizes in a solitaire setting.\u003c\/p\u003e\n\n\u003ch3\u003eCan I try a teal sapphire before committing?\u003c\/h3\u003e\n\u003cp\u003eYes — select stones in this collection are available through our Try-On programme.
