1.33 Ct. Tanzanite from Tanzania

This specimen is a transparent, 1.33 carat tanzanite cut into an elegant heart shape, measuring 6.21 by 6.83 by 4.55 millimeters. The cutter chose a mixed brilliant faceting scheme to combine strong scintillation with controlled light return, and the result is a lively play of internal facets that enhances the stone carriage and symmetry. Clarity is graded as very very slightly included when evaluated at eye level, indicating that the stone presents as eye clean to typical observation while retaining natural character under magnification. Color is described as intense violet, a hue that communicates depth without becoming overly dark, and the polish is excellent, ensuring crisp facet junctions and high surface luster. The material has been heat treated, a stable and widely accepted enhancement for tanzanite that brings forward its violet to blue tones, and the combination of treatment and precise cutting allows this heart shaped gem to exhibit both saturation and brilliance in a compact, wearable size.

The origin of this tanzanite is Tanzania, a factor that materially contributes to the gem expected value and collector interest. Tanzanite is renowned for its unique geographic restriction, with commercial deposits found only in the Merelani area of northern Tanzania, and that geological singularity creates a scarcity profile unlike many other gemstones. Provenance from Tanzania carries associations of mineralogical authenticity, documented supply chains, and a well established trade history that gem professionals and buyers recognize. For connoisseurs and designers, a Tanzanian origin supports both aesthetic and investment considerations, because geographic rarity and consistent quality from the region are part of what drives market preference. At The Natural Gemstone Company we include origin information in our product specifics to provide transparency and to link each piece to its geological story, and our assessment reflects the established standards for tanzanite grading and disclosure.

From a practical and design perspective, this heart shaped, mixed brilliant tanzanite is suitable for a range of jewelry applications where a focal gem is desired, including pendants, solitaire rings, and bespoke settings where the heart silhouette is highlighted. The intense violet saturation and excellent polish make facet reflections prominent under both natural and artificial light, while the very very slightly included clarity means the stone holds visual purity when set close to the skin. Heat treatment is stable and does not require special handling beyond standard precautions for colored gemstones, and routine care involves avoiding sustained exposure to heat and harsh chemicals, and cleaning with warm soapy water or an ultrasonic cleaner if the mounting permits. The dimensions and weight favor comfortable wear and practical setting options, and our specialists at The Natural Gemstone Company can advise on bezel and prong configurations that protect the heart cleft and apex while maximizing light performance. This tanzanite represents a balance of origin, craftsmanship, and gemological quality, described precisely to support informed selection and confident use.
