1.70 Ct. Aquamarine from Brazil

This exquisite aquamarine from The Natural Gemstone Company is a transparent 1.70 carat radiant shape stone, with precise dimensions of 8.70 x 5.52 x 5.18 mm, an excellent polish, and a vivid Santa Maria blue color intensity. The radiant cut has been chosen to maximize both the stone color and its light return, combining trimmed corners with a faceting pattern that amplifies internal fire while maintaining a broad table for color saturation. The vivid Santa Maria tone is rare and sought after by connoisseurs, and because this specimen is from Brazil, it benefits from the classic Brazilian color profile that collectors particularly prize. No enhancement has been applied to this gem, meaning the color and clarity you see are wholly natural, which enhances its desirability to an educated buyer who values authenticity and geological provenance.

Clarity has been evaluated at eye level as slightly included, which in practical terms means the stone contains natural inclusions that are noticeable under careful inspection, but they do not compromise the stone transparency or brilliance in typical jewelry settings. Slight inclusions are common in naturally formed aquamarines and often serve as reliable indicators of natural origin, especially when corroborated with the absence of treatments. For those who value gemological integrity, a slightly included grade is often acceptable and in some cases preferred over heavily treated alternatives, because it preserves the stone natural character. The excellent polish further enhances surface brightness, so the faceting lines remain crisp, and the visual impact of the Santa Maria blue is preserved even in smaller viewing conditions.

From a durability perspective it is important for buyers to understand where aquamarine stands on the Mohs hardness scale, because this will inform how the stone performs in everyday wear. Aquamarine is a variety of beryl, and it scores approximately 7.5 to 8 on the Mohs scale, which places it well above common jewelry minerals such as quartz, and just below topaz which is around 8, corundum which includes sapphire and ruby at 9, and far below diamond at 10. This means the stone is hard enough for regular wear in rings and bracelets, but it is not impervious to abrasion or sharp impacts. For best long term performance we recommend protective setting styles such as bezels or sturdy prongs for finger jewelry, and advise care when engaging in manual work to avoid chipping along facet junctions. The natural toughness of beryl is generally good, but like all gemstones, aquamarine benefits from thoughtful setting and occasional professional inspection.

For the informed buyer considering provenance, the Brazilian origin of this aquamarine adds tangible value, because Brazilian deposits are historically linked to some of the most desirable blue tones, and collectors recognize the Santa Maria designation as a benchmark for pure, saturated blue color. At 1.70 carats and with the radiant cut proportions provided, this gem offers a balanced combination of presence and wearability, suitable for both a high quality solitaire ring and a bespoke pendant where the natural blue can be shown to best effect. At The Natural Gemstone Company we prioritize full disclosure, and this gem is offered as a naturally occurring, untreated aquamarine with documented clarity at eye level, vivid Santa Maria color intensity, and excellent polish. Should you wish, we can assist with recommended mounting options and provide guidance on complementary metal choices that will accentuate the blue while protecting the stone.
