20.16 Ct.Tw.Total Carat Weight Amethyst Pair from Bolivia

A halo setting is about more than sparkle, it is about presence, contrast, and identity, and these two Bolivian amethysts from The Natural Gemstone Company deliver all three with authority, craftsmanship, and natural beauty. At 9.72 carats and 10.44 carats respectively, each stone already begins with a scale of presence that far exceeds the small center stones commonly offered in the market. Many available amethysts are modest in size, often heat treated or glassy in tone, and designed for inexpensive mass production. These fancy shaped purple amethysts are the opposite. Their substantial carat weights and unusual, elegant profiles announce a design intention rather than compromise, and when set as a pair in matched halo settings they will read as intentional, luxurious, and instantly distinctive. The Natural Gemstone Company sources and presents these gems as natural, untreated treasures, and that provenance matters in a halo that aims to be noticed for its authenticity as much as for its brilliance.

Look closely at the gemological details and you see why these amethysts outclass the commonplace options. The pair measures 17.16 x 13.80 x 8.28 mm and 17.13 x 13.81 x 8.44 mm, a near perfect match that is rare for stones of this size. They are fancy shapes, step cut, with intense color intensity and an excellent polish, characteristics that combine to make halos sing rather than merely shimmer. Step cuts create broad, mirror like facets that emphasize depth of color and clarity, and with a clarity grade of very very slightly included evaluated at eye level these stones maintain a clean, transparent field with only the most minor inclusions visible to a trained eye. Because they are not enhanced, the color is authentically Bolivian, and the light that returns to the viewer is a product of nature and masterful cutting alone. In a halo setting the step facets will interact with the surrounding melee in a complementary way, producing flashes of rich purple within a frame of scintillating white, warm, or colored metal, depending on the design choice.

When comparing these amethysts to other market alternatives, several advantages become obvious. First, many commercial amethyst options are heat treated to even out tone, or they are synthetic and lack the nuanced depth that a natural Bolivian stone offers. Others are standard oval or round shapes that can disappear into predictable design language, especially when paired with a halo that relies solely on small diamonds for drama. These Bolivian step cut amethysts will instead anchor the design. Their large table and deep pavilion invite a halo to act as a stage rather than a mask, so that the surrounding diamonds or colored stones accentuate the purple rather than compete with it. The precision of the excellent polish ensures that light transitions are clean, reducing glare and allowing the halo to pick up and mirror the amethyst color for a cohesive and striking visual. Because the pair is closely matched in size and proportion, a designer can create mirror image halos that read as a set, lending an elevated symmetry that cheap matched pairs rarely achieve. Value wise, selecting natural, untreated stones from a reputable source such as The Natural Gemstone Company means that buyers receive integrity in both material and description, a feature that supports long term satisfaction and potential resell value, unlike mass market alternatives that often rely on undisclosed treatment or inconsistent matching.

Finally, consider practical styling scenarios where these amethysts will stand out. In a white diamond halo the contrast will be electric, the white metal and bright melee producing a ring of light that frames the intense purple like a stage spotlight. In yellow gold the warm metal will add depth and vintage glamour, amplifying the warmth in the purple and creating a regal, heirloom worthy feel. In rose gold the overall effect will be romantic and modern, with the pink of the metal harmonizing with violet undertones for a softer, fashion forward statement. The step cut also lends itself to designs that emphasize geometry, so hexagonal halos, architectural milgrain, and double halo compositions will all benefit from the broad, flat planes of the amethysts. For designers these stones are a dream because their dimensions and matching quality minimize the need for compromise in bezel or prong placement. For clients these stones are superior because the central color and clarity are allowed to read with maximum authority, and because they are natural and unenhanced the wearer will know that the vivid purple is genuine, sourced responsibly, and intended to last as a signature piece in any jewelry collection.

These Bolivian amethysts from The Natural Gemstone Company represent an opportunity to choose distinction over conformity, authenticity over artificiality, and design freedom over constraint. They are a matched pair, 9.72 carats and 10.44 carats, step cut and intensely colored, with dimensions of 17.16 x 13.80 x 8.28 mm and 17.13 x 13.81 x 8.44 mm, clarity graded very very slightly included at eye level, excellent polish, and no enhancement. When set in a halo the result will be a confident focal point that commands attention while remaining refined, a piece that benefits both from its natural origin and from the considered cutting that makes it perform in jewelry. If you are comparing options for a signature halo piece, consider that these amethysts allow the halo to elevate the center stone rather than conceal it, delivering a balance of brightness, color depth, and designer friendly proportions that is difficult to find in the broader market. For a halo that needs to be remembered, these gems will not only stand out, they will define the style.
