This exceptional blue aquamarine from The Natural Gemstone Company is a beautifully transparent 16.58 carat emerald cut, presented with precise proportions and clean lines, giving it a refined presence suitable for both classic and contemporary jewelry, the stone measures 17.17 x 12.46 x 10.05 mm, and its emerald cut emphasizes broad step facets that create elegant flashes of light along the table and pavilion, the medium intense color intensity delivers a pleasing and versatile blue that reads vividly in natural daylight without appearing overly dark, and the excellent polish produces crisp facet junctions and a silky surface finish that enhances overall brilliance and hand appeal.
From a gemological perspective the aquamarine is an attractive example of the beryl family, exhibiting a clarity grade of eye clean when viewed at normal eye level, this means there are no inclusions readily visible to the unaided eye, a feature that adds significant value for connoisseurs who prioritize clean stones, the stone has been heat treated, a widely accepted and stable enhancement for aquamarine that improves blue saturation by reducing greenish tones, heat treatment is permanent under normal wear conditions and is commonly used by responsible dealers to present the material at its best, the Brazilian origin is notable, as Brazil consistently yields high quality aquamarines with appealing tonal range and good crystal clarity, and the combination of weight, dimensions and cut make this piece a rare find for its size class.
This aquamarine is exceptionally adaptable to customization, and it lends itself to a wide variety of settings for different tastes and lifestyles, for a signature ring a classic four or six prong solitaire will showcase the table and step facets while protecting the corners, a halo of graduated round or tapered baguette diamonds will enhance perceived color and add scintillation, a three stone composition with tapered baguettes or trapezoids will emphasize length and symmetry, for everyday wear a low bezel or semi bezel will provide extra security and a sleek profile, whereas a cathedral or high gallery mounting will give the gem more presence for formal pieces, metal choices will influence the appearance of the blue, white metals such as platinum or 18k white gold will present a crisp modern look, yellow or rose gold will warm the overall feel and can be paired with accent diamonds or colored gemstones for contrast, beyond rings this size and shape are ideal for a striking pendant with a simple bail to allow light through the pavilion, matched pair creation is a thoughtful option for earrings when two similar stones are available, and the substantial depth at 10.05 mm also makes the gem well suited to cufflinks and bespoke brooches or signet style settings that benefit from three dimensional presence.
