5.37 Ct. Purple Amethyst from Brazil

This piece is a transparent, faceted purple amethyst with a precise weight of 5.37 carats, and dimensions of 12.92 millimeters by 9.42 millimeters by 6.50 millimeters. The cutting style is a classic emerald cut, executed with stepped rectangular facets that define the crown and pavilion planes. Color has been evaluated as intense, yielding a saturated purple hue with strong saturation across the table and well defined color zoning only at certain viewing angles. Clarity is graded as slightly included when assessed at eye level, and those internal characteristics are subtle within the step facet architecture. The polish has been completed to an excellent finish, producing crisp facet junctions and mirror like facets that enhance transmitted light. There are no enhancements to this material, and the origin of the rough is Brazil, which contributes to the consistent crystalline structure and color stability associated with South American amethyst deposits. This combination of weight, transparency, and faceting quality situates the specimen as a premium choice for bespoke jewelry applications.

From a proportion and faceting perspective, the stone presents an optimal depth profile for an emerald cut, with the depth measuring 6.50 millimeters relative to the average of the length and width, producing a depth of 58.2 percent. That depth proportion balances pavilion depth and crown height to favor even color distribution and efficient light return in a step cut geometry. The emerald cut facet arrangement emphasizes broad flashes of color rather than scintillation, and the cutter has aligned the step rows to the crystallographic axis to preserve color saturation across the table. Facet symmetry is consistent, showing parallel step rows and squared corner bevels that reduce vulnerability in setting applications. The excellent polish contributes to uninterrupted light transmission, and the slightly included clarity at eye level is mitigated by the broad facet planes, which tend to mask small internal features when properly oriented in jewelry. Overall, the faceting and proportions are tuned to maximize the amethyst's intrinsic color and to present a stable, predictable window of light performance for designers and setters.

The physical dimensions and rectilinear outline make this 5.37 carat emerald cut amethyst highly adaptable for custom jewelry work, particularly as a center stone for rings, pendants, and brooches. The 12.92 by 9.42 millimeter table provides a generous visual face up area, ideal for single stone solitaire designs or for being flanked by accent stones in channel or semi bezel settings. The depth of 6.50 millimeters allows for secure seatings in conventional ring shells without excessive raising of the crown, and the squared corners with subtle bevels lend themselves to four corner prong protection or a closed bezel that preserves the step cut silhouette while providing mechanical security. Jewelry designers will appreciate the way the step facets interact with side accent stones, creating a layered optical relationship when paired with tapered baguettes or micro pavé diamonds. For pendant applications, the stone sits proportionally for both vertical and horizontal orientations, and the intense color reads strongly in both natural and controlled lighting, reducing the need for specialized lighting to achieve desired visual impact.

In terms of sourcing, care, and customization options, this amethyst arrives to you untreated, with a provenance from Brazil, and with finishing consistent with high quality lapidary standards. The stability of amethyst on the Mohs scale of hardness is sufficient for everyday wear when set with prudent protective settings and when routine care avoids strong acids and prolonged exposure to high heat. For custom commissions, The Natural Gemstone Company can provide consultation on setting geometry including crown clearance, prong thickness, bezel wall specifications, and complementary accent stone selection to optimize color contrast and structural integrity. Because the material exhibits intense purple saturation and controlled internal character, it rewards precision mounting to maintain its optical performance. For designers and clients seeking a substantial, well proportioned emerald cut amethyst with superior polish and natural origin, this 5.37 carat specimen offers a technically refined platform for a wide range of custom jewelry concepts, and our team is available to advise on secure, elegant mounting strategies that preserve both beauty and durability.
