0.65 Ct. Rainbow Moonstone from Ceylon (Sri Lanka)

This listing presents one transparent 0.65 carat pear shape rainbow moonstone, with precise dimensions of 5.70 by 5.60 by 4.10 mm, cut to a mixed brilliant faceting scheme, carrying a clarity grade of very very slightly included when evaluated at eye level, exhibiting light color intensity, and finished with an excellent polish. The stone is natural with no enhancement, and its origin is Ceylon Sri Lanka. At The Natural Gemstone Company we document these attributes to provide clear, verifiable information for discerning collectors and jewelers who require precise gemological data prior to making a selection. The combination of a measured weight near two thirds of a carat, compact yet well balanced dimensions, and a refined mixed brilliant cut make this piece suitable for applications where optical performance and proportional harmony are priorities.

Visually the gem reads as highly transparent with the characteristic sheen of rainbow moonstone, presenting subtle spectral flashes that shift with movement and light direction. The mixed brilliant cut maximizes the return of light through a balanced arrangement of crown and pavilion facets, translating internal clarity and polish into a lively yet refined appearance. Given the clarity grade of very very slightly included at eye level, inclusions are minimal and do not detract from the gem when viewed in normal wear conditions, so the eye is greeted primarily by clean brilliance and the soft, cool iridescence associated with this material. The light color intensity gives the stone a versatile, near neutral tone that complements both white and warmer metal settings while allowing the internal play of color to remain the focal feature.

Our approach to sourcing and supply chain transparency underpins the presentation of this moonstone, and it is central to how we at The Natural Gemstone Company curate inventory for conscious consumers. This gem was sourced from established artisanal mining areas in Ceylon Sri Lanka, and it was acquired through channels that we monitor for adherence to responsible labor practices and environmental stewardship. The fact that the stone is untreated, with no enhancement, is important for buyers seeking authentic, natural material, as it preserves original formation characteristics and ensures the gem will age and respond to settings in predictable ways. We maintain direct relationships with cutters and local partners in Sri Lanka, and we prioritize small scale operations that provide fair compensation and that are committed to minimizing ecosystem disturbance, while also supporting traceability back to origin in a manner consistent with best practices for ethical procurement.

For the conscious collector, this pear shape rainbow moonstone integrates into a curated collection in ways that reflect both aesthetic taste and ethical standards. Its measured size and elegant cut make it well suited to a refined solitaire ring, an understated pendant, or a delicate pair of stud settings where its transparency and adularescence can be appreciated without excessive bezel mass. Because the gem is natural and untreated, it holds value as an authentic specimen and it aligns with collecting philosophies that favor minimal intervention and durable provenance. We advise that the stone be set with consideration for daily wear, employing protective settings when used in rings, and that routine care be straightforward, using mild cleaning and avoiding exposure to harsh chemicals. Prospective buyers are welcome to request additional images, a detailed inventory sheet, and documentation of origin and handling at each stage of the supply chain, as part of The Natural Gemstone Company commitment to transparency and to supporting informed, thoughtful acquisitions.
