{"title":"1克拉以上紅寶石","description":"\u003ch2\u003eNatural Ruby Over 1 Carat — Loose Stones with GIA Reports, Direct from Source\u003c\/h2\u003e\n\n\u003cp\u003eNatural ruby above 1 carat is one of the rarest commercially available gemstones on earth. At this size, fine colour, eye-clean clarity, and the presence or absence of heat treatment each have an exponential effect on price and collectibility. Every stone in this collection is natural corundum coloured by chromium, accompanied by a GIA laboratory report, and sold with complete treatment disclosure.\u003c\/p\u003e\n\n\u003cp\u003eRuby is the red variety of corundum — the same mineral family as sapphire, sharing a Mohs hardness of 9. Only diamond is harder. This makes ruby one of the most durable gemstones available for fine jewellery, engagement rings, and long-term collection.\u003c\/p\u003e\n\n\u003ch2\u003eWhy 1 Carat Is the Critical Threshold for Ruby\u003c\/h2\u003e\n\n\u003cp\u003eRuby pricing does not scale linearly with carat weight. A 1ct ruby in fine colour does not cost twice a 0.50ct stone — it typically costs four to eight times as much. The reason is scarcity of rough. Gem-quality ruby rough large enough to yield a 1ct finished stone with acceptable colour and clarity is genuinely rare. The overwhelming majority of ruby mined globally is either too included, too pale, or too dark to qualify as gem-grade. Among that minority, most is cut into sub-1ct stones to maximise recovery.\u003c\/p\u003e\n\n\u003cp\u003eThe result is a market where every 1ct+ ruby in fine colour and clean clarity is effectively an individual stone with its own story, and where GIA documentation is not optional — it is the instrument that makes a stone verifiable, insurable, and resaleable.\u003c\/p\u003e\n\n\u003ch2\u003eOrigins — Where Our Rubies Come From\u003c\/h2\u003e\n\n\u003cp\u003eThe most prestigious ruby origins in the world are Myanmar (Burma), Mozambique, and Sri Lanka (Ceylon). Each produces rubies with distinct character.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMyanmar (Mogok and Mong Hsu)\u003c\/strong\u003e produces the benchmark for ruby — a pure, vivid red with slight blue fluorescence, described as \"pigeon's blood\" at the finest quality. Mogok rubies are among the most sought-after coloured gemstones in the world and command the highest origin premiums. \u003cstrong\u003eMozambique\u003c\/strong\u003e has emerged since the 2000s as the most commercially important ruby source, producing stones with comparable colour to Burma at lower origin premiums, making them the dominant source for GIA-documented rubies in the current market. \u003cstrong\u003eSri Lanka (Ceylon)\u003c\/strong\u003e produces rubies that tend toward lighter pinkish-red — distinct from the deeper Burmese and Mozambican tones, and often unheated.\u003c\/p\u003e\n\n\u003cp\u003eGIA laboratory reports can confirm geographic origin for many rubies. We disclose origin on every listing and carry GIA origin reports where available. For questions about a specific stone's source, email \u003ca href=\"mailto:crescentgems@gmail.com\"\u003ecrescentgems@gmail.com\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eHeated vs Unheated Ruby — What It Means Over 1 Carat\u003c\/h2\u003e\n\n\u003cp\u003eHeat treatment in ruby — typically involving temperatures of 1,200°C to 1,800°C — is the industry standard, used to improve colour saturation and reduce the visibility of inclusions. Estimates vary but the majority of commercial rubies have been heat treated. The treatment is permanent and accepted universally by laboratories and the trade.\u003c\/p\u003e\n\n\u003cp\u003eUnheated rubies — stones that have received no thermal enhancement — are significantly rarer, particularly above 1 carat. At this size, an unheated ruby with strong colour and a GIA report is a genuinely scarce object. The premium for unheated over equivalent heated stones typically runs 50–200% at the 1ct mark and widens sharply above 2ct. For collectors and investment buyers, unheated status with laboratory confirmation is the highest-value combination in ruby.\u003c\/p\u003e\n\n\u003cp\u003eThis collection includes both heated and unheated stones. Treatment status is clearly stated on every product listing and confirmed by the accompanying GIA report.\u003c\/p\u003e\n\n\u003ch2\u003eUnderstanding the GIA Ruby Report\u003c\/h2\u003e\n\n\u003cp\u003eEvery stone in this collection ships with a GIA Colored Stone Identification and Origin Report or GIA Colored Stone Report. These documents confirm the following for each stone: species (corundum) and variety (ruby), carat weight and dimensions, shape and cutting style, colour description, clarity grade, and treatment status. Where origin determination is possible, geographic source is also stated.\u003c\/p\u003e\n\n\u003cp\u003eThe GIA report is the most widely recognized coloured stone documentation globally. It is accepted by auction houses, insurance companies, customs authorities, and collectors worldwide. For a ruby over 1 carat, a GIA report is the baseline expectation for any serious transaction.\u003c\/p\u003e\n\n\u003ch2\u003eRuby Over 1 Carat for Engagement Rings\u003c\/h2\u003e\n\n\u003cp\u003eA 1ct+ ruby makes a striking and durable engagement ring centerpiece. Ruby's hardness of 9 on the Mohs scale makes it entirely suitable for daily wear — more durable than emerald (7.5–8), tanzanite (6.5–7), or opal (5.5–6.5). A 1ct oval ruby measures approximately 7×5mm; a 1ct cushion runs approximately 6mm across — both proportionate for most ring settings.\u003c\/p\u003e\n\n\u003cp\u003eFor engagement ring buyers, a heat-treated ruby in vivid colour is typically the right choice. The visual result is indistinguishable from unheated, the durability is identical, and the price is significantly more accessible. If budget allows and natural origin matters intrinsically — for investment, collection, or sentiment — the unheated option is available in this collection with full GIA documentation.\u003c\/p\u003e\n\n\u003cp\u003eRuby pairs beautifully with yellow gold (warm contrast) and white gold or platinum (cool contrast, maximises colour impact).

The standard requirements for a Jyotish ruby are: natural corundum, no heat treatment, eye-clean, vivid red with no brown modifier, and a minimum of 1.5–3ct depending on the practitioner. The unheated 1.83ct GIA ruby in this collection meets those specifications. See our \u003ca href=\"\/zh-hant-ca\/blogs\/information-pages-complete-guide\/buying-sapphires-for-jyotish-vedic-astrology\"\u003eJyotish gemstone guide\u003c\/a\u003e for full prescribing specification — the same principles for sapphire apply equally to ruby.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow much does a 1 carat natural ruby cost?\u003c\/h3\u003e\n\n\u003cp\u003eA 1ct natural ruby with a GIA report in good colour and heat treated typically ranges from $2,500 to $5,000 total, depending on colour saturation, clarity, and cut quality. Vivid, eye-clean stones in this size range run $4,000–$8,000. Unheated 1ct rubies in strong colour start at approximately $5,000 and can reach $15,000+ depending on origin and saturation. Price per carat is the most useful comparison metric — every listing in this collection shows it.\u003c\/p\u003e\n\n\u003ch3\u003eIs a 1 carat ruby bigger than a 1 carat diamond?\u003c\/h3\u003e\n\n\u003cp\u003eA 1ct ruby appears slightly smaller than a 1ct diamond face-up because ruby has a higher specific gravity (heavier per unit volume). A 1ct round ruby measures approximately 6mm in diameter, compared to 6.4mm for a 1ct round diamond. In oval and cushion cuts — the most common shapes for ruby — a 1ct stone measures approximately 7×5mm, which gives a larger face-up appearance than a round of the same weight.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between a heated and unheated ruby?\u003c\/h3\u003e\n\n\u003cp\u003eVisually, a well-selected heated ruby can be indistinguishable from an unheated one. The difference lies in rarity and market premium. Unheated rubies — those showing no evidence of thermal enhancement under laboratory examination — are significantly rarer at 1ct+, command a premium of 50–200% or more over equivalent heated stones, and are preferred by collectors, investors, and Jyotish buyers. GIA reports state treatment status definitively. All stones in this collection carry GIA reports with treatment status confirmed.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is \"pigeon's blood\" ruby?\u003c\/h3\u003e\n\n\u003cp\u003ePigeon's blood is a trade term for the most prized shade of red in ruby — a pure, vivid red with a slight blue-violet component and strong red fluorescence, typically associated with Burma (Mogok) origin. GIA and other laboratories can formally designate a stone as pigeon's blood colour grade when it meets the specification. Pigeon's blood rubies command the highest premiums in the ruby market.
