{"title":"Ceylon Blue Sapphire Over 1 Carat","description":"\u003ch2\u003eNatural Ceylon Blue Sapphire Over 1 Carat — Loose Stones, Direct from Sri Lanka\u003c\/h2\u003e\n\n\u003cp\u003eCeylon blue sapphires above 1 carat occupy a different category from sub-carat stones — in price, in presence, and in collector significance. The 1-carat threshold is a genuine step change: prices per carat rise sharply, unheated stones become rarer, and GIA documentation becomes the standard expectation. Every stone in this collection is natural, sourced directly through our buying offices in Colombo, Beruwala, and Ratnapura, and sold with full treatment disclosure.\u003c\/p\u003e\n\n\u003ch2\u003eWhy 1 Carat Is the Threshold That Matters\u003c\/h2\u003e\n\n\u003cp\u003eIn coloured gemstones, carat weight thresholds affect price non-linearly. A 1.00ct Ceylon blue sapphire does not simply cost twice a 0.50ct stone of similar quality — it typically costs three to five times as much. This happens because fine-quality rough large enough to yield 1ct+ finished stones is genuinely scarcer, and because market demand concentrates heavily at and above the 1-carat mark for engagement rings and collector acquisitions.\u003c\/p\u003e\n\n\u003cp\u003eAbove 1 carat, individual stone character becomes the dominant value driver. Two 1.5ct Ceylon blues in the same hue range can differ by 300% in price based on saturation, clarity, cut quality, and whether the stone is heated or unheated. This collection brings together the full range so you can compare directly.\u003c\/p\u003e\n\n\u003ch2\u003eWhat to Look for in an Over-1-Carat Ceylon Blue Sapphire\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eHue and saturation.\u003c\/strong\u003e The most prized position in blue sapphire is medium-vivid to vivid saturation with a pure blue to slightly violet-blue hue — what the trade calls cornflower blue at the lighter end and royal blue at the deeper end. Stones that appear inky or very dark lose colour in low light. Stones with strong greyish or greenish modifiers are valued significantly less. We describe colour honestly on every listing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTreatment status.\u003c\/strong\u003e At 1ct+, the heated versus unheated distinction carries serious financial weight. A vivid, unheated 1.5ct Ceylon blue sapphire with GIA documentation can command two to four times the price of an equivalent heated stone. Browse our \u003ca href=\"\/en-jp\/collections\/ceylon-blue-sapphire-natural-unheated-sri-lankan-stones\"\u003eunheated blue sapphires\u003c\/a\u003e specifically if natural-colour origin is your primary criterion.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGIA documentation.\u003c\/strong\u003e For stones above 1 carat, a GIA report documenting weight, dimensions, treatment, and where determinable, origin, is the industry standard. Most stones in this collection ship with GIA reports. For those that do not, independent lab reports are available and disclosed on the listing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCut.\u003c\/strong\u003e At this weight, cut quality significantly affects perceived size and brilliance. Oval and cushion cuts dominate the over-1-carat Ceylon blue market because they retain more of the rough's weight while producing a large face-up appearance. Round cuts are rarer and command a premium at this size. Emerald and radiant cuts suit modern geometric settings.\u003c\/p\u003e\n\n\u003ch2\u003ePrice Ranges at Over 1 Carat — What to Expect\u003c\/h2\u003e\n\n\u003cp\u003ePricing at 1ct+ in Ceylon blue sapphire spans a very wide range depending on quality. As a general guide: heated stones in good colour and clarity from 1.0–1.5ct typically run $800–$2,500 per carat. Vivid, eye-clean heated stones in the 2–3ct range run $2,500–$5,000 per carat. Unheated stones in vivid colour start at $1,500–$3,000 per carat at 1ct and rise steeply above 2ct. GIA-documented unheated stones in fine colour above 3ct can exceed $5,000–$10,000 per carat. Every listing shows the price per carat alongside the total price so you can compare across sizes.\u003c\/p\u003e\n\n\u003ch2\u003eCeylon Blue Sapphire for Engagement Rings — Over 1 Carat\u003c\/h2\u003e\n\n\u003cp\u003eFor an engagement ring solitaire, a 1.0–1.5ct Ceylon blue sapphire in an oval or cushion cut is the most popular choice — large enough to have strong visual presence, proportionate on most hand sizes, and accessible relative to 2ct+ pricing. A 6.5–7.5mm oval in this weight range sits well in most standard settings. For a more dramatic statement piece, 2ct+ stones are available in this collection with GIA documentation.

Several stones in this collection meet these criteria with GIA origin documentation.

Unheated stones in the same size start at $1,500 and rise significantly with colour quality. Fine vivid heated stones with GIA reports sit toward the upper end of that range.\u003c\/p\u003e\n\n\u003ch3\u003eIs a 1 carat sapphire big enough for an engagement ring?\u003c\/h3\u003e\n\u003cp\u003eYes. A 1ct oval Ceylon blue sapphire measures approximately 7×5mm and has strong visual presence in a ring setting. A 1ct round measures approximately 6.3mm. Both are proportionate for most hand sizes. For buyers who prefer a larger look, a well-cut 1.2–1.5ct oval or cushion can appear significantly larger than a round stone at the same carat weight due to its elongated shape.\u003c\/p\u003e\n\n\u003ch3\u003eDo over-1-carat Ceylon sapphires come with GIA reports?\u003c\/h3\u003e\n\u003cp\u003eMost stones in this collection ship with GIA reports.

Unheated stones are rarer, more collectible, and command a premium of 50–200% over equivalent heated stones. For investment buyers and collectors, unheated is the strong preference. For engagement ring buyers whose priority is colour and beauty, a well-cut heated stone delivers equivalent visual performance.

Ceylon Royal blue in an emerald cut at 1.32 carats is genuinely uncommon in the market, where oval and cushion formats dominate. The AGCL report (#M263858) confirms the weight, dimensions, and heat treatment. The step facets in a vivid deep blue create a hall-of-mirrors effect that makes this stone look larger and more architectural than its carat weight suggests.\u003c\/p\u003e\n\n\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eKey Benefits of this Natural Blue Sapphire\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCeylon Origin\u003c\/strong\u003e\u003cbr\u003eSri Lanka — the primary source for vivid, transparent blue sapphire at the fine commercial level.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmerald Cut Distinction\u003c\/strong\u003e\u003cbr\u003eArchitectural step-cut format — the choice when depth and structure matter more than brilliance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoyal Blue Visual Weight\u003c\/strong\u003e\u003cbr\u003eRichly saturated, medium-dark tone — maximum visual presence in blue sapphire.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUncommon Format-Color Combination\u003c\/strong\u003e\u003cbr\u003eEmerald-cut Ceylon Royal blue at this size is not commonly available in the market.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable for Daily Wear\u003c\/strong\u003e\u003cbr\u003eCorundum at Mohs 9, second only to diamond.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003eCarat Weight: 1.32 Carats\u003c\/li\u003e\n\u003cli\u003eGem Type: Natural Blue Sapphire\u003c\/li\u003e\n\u003cli\u003eVariety: Blue Sapphire\u003c\/li\u003e\n\u003cli\u003eDimensions: 7.24 x 5.53 x 3.40 mm (per AGCL report)\u003c\/li\u003e\n\u003cli\u003eShape: Emerald Cut\u003c\/li\u003e\n\u003cli\u003eCut Style: Emerald Cut (Step Cut faceting)\u003c\/li\u003e\n\u003cli\u003eOrigin: Sri Lanka (Ceylon)\u003c\/li\u003e\n\u003cli\u003eTreatment: Heat Treated — Indication of Heating (per AGCL report)\u003c\/li\u003e\n\u003cli\u003eColor: Royal Blue\u003c\/li\u003e\n\u003cli\u003eClarity: Eye-clean — no visible inclusions under normal viewing\u003c\/li\u003e\n\u003cli\u003eHardness: 9 on the Mohs scale\u003c\/li\u003e\n\u003cli\u003eCertification: AGCL (Arctic Gem Certification \u0026amp;
