Tanzanite comes from a single source on earth, the area around Mount Kilimanjaro in Tanzania, and at 15.34 carats, this princess cut stone represents a substantial size within that limited supply.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe princess cut is a square or rectangular brilliant style known for maximizing brightness and fire through its faceting pattern, and it suits tanzanite well by highlighting the stone's pleochroism, the way its color shifts subtly between blue and violet depending on the viewing angle. Measuring 13.53 x 12.25 x 10.96 mm, this stone has real presence as a center piece, whether set into a ring, pendant, or custom jewelry commission. D-Block material at this carat weight represents the upper end of what the tanzanite market produces, since the combination of top grade color and substantial size doesn't come to market often.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eDetail\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eInformation\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e15.34 Carats\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e13.53 x 12.25 x 10.96 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShape\u003c\/td\u003e\n\u003ctd\u003ePrincess\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor Grade\u003c\/td\u003e\n\u003ctd\u003eD-Block (Top Saturation Tier)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClarity\u003c\/td\u003e\n\u003ctd\u003eNot specified in source data\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTreatment\u003c\/td\u003e\n\u003ctd\u003eNot specified in source data\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eTanzania\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardness\u003c\/td\u003e\n\u003ctd\u003e6 to 7 (Mohs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFamily\u003c\/td\u003e\n\u003ctd\u003eZoisite (Tanzanite Variety)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cstrong\u003eGemstone Properties\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eBirthstone: December\u003c\/li\u003e\n\u003cli\u003eZodiac Sign: Sagittarius\u003c\/li\u003e\n\u003cli\u003eChakra: Third Eye Chakra, Crown Chakra\u003c\/li\u003e\n\u003cli\u003eHealing Properties: Tanzanite is often associated with clarity of thought and spiritual insight, tied to the upper chakras in crystal healing practice.
