23.74 Ct.Tw.Total Carat Weight Blue Aquamarine Pair from Brazil

This exceptional matched pair of transparent aquamarines presents 12.60 carats and 11.14 carats respectively, each masterfully cut in an emerald shape that emphasizes elongated step facets and a broad table for crisp clarity and architectural light return. The dimensions are 20.26 x 11.29 x 7.39 mm, and 20.24 x 11.30 x 6.47 mm, with length and width virtually identical, creating an elegant visual symmetry that is essential for matched stones. Both gems exhibit a light blue color intensity and are graded eye clean at eye level, which indicates that inclusions do not interrupt the visual plane for a viewer without magnification. The polish is excellent, creating sharp facet junctions and smooth planes that maximize brilliance in a step cut. There is no enhancement, the material is natural aquamarine from Brazil, and buyers can expect the typical beryl refractive index near 1.577 to 1.583 and a Mohs hardness around 7.5 to 8, qualities that combine attractive optical performance with reliable durability for wearable designs.

Pairing these aquamarines required technical precision at every stage, from rough selection to final faceting, because achieving a matched set demands strict control of proportions and optical behavior. Emerald cuts rely on proportional relationships such as table size, pavilion depth, and crown angle to control how light travels through the stone, and small variations in depth can alter face up color and windowing, which explains the slightly different depths in this pair and the tasteful balance achieved by the cutter. For the educated buyer, important matching criteria include near identical length to width ratios, comparable table percentages, consistent clarity under loupe and at eye level, and matched polish quality, all of which are evident here. These stones are ideal for paired earrings, a two stone pendant, or an asymmetric yet coordinated ring design where matched width and length are critical to aesthetics. The Natural Gemstone Company offers this pair with transparent sourcing, and we can provide supplementary measurements and standardized photography to assist gemologists, setters, and designers in making an informed decision, ensuring the technical compatibility of the pair for your finished piece.
