5.62 Ct. Star Ruby from Vietnam

This beautiful opaque 5.62 carat oval shape red star ruby from Vietnam is a striking example of classic asterism, with precise measurements of 10.63 x 9.97 x 4.60 mm, a cabochon cut, and an eye catching six ray star that appears crisply centered when viewed under direct light. The gem displays vivid color intensity, an excellent polish that enhances surface luster, and a clarity grade of very slightly included as evaluated at eye level, which means it appears clean to the unaided eye while retaining the natural silk inclusions that produce the sharp star effect. This piece has no enhancement, a feature that contributes meaningfully to its desirability for collectors and connoisseurs who value natural, untreated rubies. The combination of deep red color and well centered asterism makes this oval cabochon versatile for statement jewelry, while the substantial 5.62 carat weight provides presence without overwhelming a design.

At The Natural Ruby Company we present this Vietnamese star ruby as a rare opportunity to own a naturally occurring, untreated example of asterism, ideal for a bespoke ring or a distinguished pendant that showcases the star in motion under changing light. The cabochon profile and excellent polish lend themselves well to bezel and halo settings that protect the domed surface while allowing the star to be the visual focus, and the durable nature of corundum makes this gem suitable for everyday wear with prudent care. We recommend cleaning with warm soapy water and a soft brush, avoiding harsh chemicals and extreme heat, and consulting a trusted jeweler for secure mounting. For collectors the natural origin and lack of enhancement are important provenance factors, and we can assist with independent laboratory reports upon request. Contact The Natural Ruby Company for high resolution images, mounting suggestions, or to arrange viewing and purchase, as availability of such naturally untreated star rubies is limited and we are happy to help you make this exceptional specimen part of your collection.
