7.38 Ct. Tanzanite from Tanzania

This exquisite blue tanzanite offered by The Natural Gemstone Company is a standout among similar gems on the market, a rare combination of size, color, and clarity that immediately places it above more common offerings. We present one beautiful transparent 7.38 carat oval shape tanzanite, with precise dimensions of 13.55 x 10.53 x 7.28 mm, a mixed brilliant cut that maximizes light return, and an excellent polish that produces crisp facet reflections. The clarity grade is eye clean, evaluated at eye level, which means the gem will read as visually flawless to most observers without magnification. The vivid color intensity is striking, a deep saturated blue that leans toward velvety violet in certain lighting, and the stone has been heat treated, a standard and stable enhancement that intensifies hue without compromising integrity. In comparison to many tanzanites that trade in lighter or less saturated tones, or that show visible inclusions, this example offers superior visual impact and durability for fine jewelry.

The origin of this gem in Tanzania elevates its value in a way that many buyers overlook, because tanzanite is essentially unique to a narrow zone in the Merelani hills. That geographic rarity gives Tanzanian tanzanite an inherent story and long term desirability, because supply is finite and concentrated, unlike sapphires or other commercial blues that are found across multiple countries. This provenance also influences market perception and resale potential, collectors and connoisseurs prize stones with verifiable origin, and The Natural Gemstone Company takes care to document and communicate origin so that buyers understand they are acquiring a stone that is both natural and regionally distinct. The association with Merelani enhances emotional and monetary value, making this gem a better long term investment than many lab grown or ambiguous origin alternatives.

When comparing this tanzanite to other gemstones in the same price range, the advantages become clear, beginning with color saturation, moving through clarity, and finishing with cut quality. Many natural tanzanites offered online are lighter in tone, heavily included, or poorly cut, which reduces apparent sparkle and requires more metal in the setting to compensate. In contrast, the mixed brilliant cut on this oval shape has been executed to balance fire and broad flash, creating lively movement across the table and step crown, which results in a gem that reads as larger visually than its carat weight might suggest. Eye clean clarity reduces the need for closed back settings and allows jewelers to design open back mounts that showcase the stone from all angles, increasing perceived value. Heat treatment on tanzanite is industry standard, stable, and accepted, and it produces a color that is more comparable to prized natural blues than many untreated alternatives, providing better value than similarly colored stones that are synthetic or heavily filled.

Choosing this tanzanite from The Natural Gemstone Company means selecting a gem that not only looks exceptional, but that is backed by expertise in sourcing and grading, which distinguishes it from mass market offerings. Our direct sourcing in Tanzania and our emphasis on ethical procurement give buyers confidence that they are acquiring a responsibly sourced, high quality gem with a documented story. For customers seeking a statement ring, a unique pendant, or a custom commission, this 7.38 carat oval tanzanite balances rarity and wearability, large enough to create a centerpiece yet cut and polished for everyday brilliance. In comparison to other blue gems such as synthetic sapphires, blue spinel, or lower grade tanzanite, this stone offers richer saturation, superior clarity, and a pedigree that supports long term collectability, qualities that matter to discerning buyers who value both beauty and provenance.
