Why Choose a Ruby Cabochon?
Ruby cabochons are valued for their smooth, rounded appearance and natural character. Unlike faceted rubies, cabochons emphasize color saturation and can display unique optical effects such as silk or subtle star-like phenomena.
Ruby Cabochons for Jewelry Making
The curved shape of ruby cabochons makes them ideal for bezel settings and artisan jewelry. They are popular choices for rings, pendants and vintage-style designs where rich color is the main focus.
Star Ruby Cabochons
Some ruby cabochons may display asterism, a star effect caused by internal inclusions. Star ruby cabochons are highly collectible and especially desirable for unique statement jewelry pieces.
Oval, Round and Fancy Ruby Cabochons
Choose from oval, round and freeform ruby cabochons in various sizes. Multiple shapes allow jewelers and collectors to find gemstones suited to both classic and modern jewelry styles.

Ruby as a Birthstone

FAQs
Are your ruby cabochons natural?
Yes, all ruby cabochons sold by GemSelect are natural gemstones. Any treatments are fully disclosed on each product page for complete transparency.
What is the difference between faceted rubies and ruby cabochons?
Faceted rubies are cut to maximize sparkle, while cabochons have a smooth polished dome that emphasizes color, natural inclusions and unique optical effects.
Are ruby cabochons good for rings?

Many ruby cabochons are available in calibrated sizes suitable for standard jewelry settings, while others are offered as unique free-size stones for custom designs.
Can I buy ruby cabochons wholesale?
Yes, we offer ruby cabochons individually and in lots or parcels, making them suitable for jewelers, designers and gemstone collectors.

I wish there were options for jewelry settings
Overall Rating -> 10 
No problems. I had a minor address issue in the past and someone got back to me very quickly and we resolved the issue satisfactorily. I appreciated the quick, concerned response. So important when buyer/seller are so far apart in distance. Thank you Gem Select. Keep up the good work!

the gems were smaller than I thought but I was at fault for not reading the complete discrimination

I was looking for high-quality amethyst on this site, and I was able to compare size, color, and weight in detail before making a purchase.

All good
Overall Rating -> 9
I was looking for a small gift for a friend- the process is the same as every other time and was very simple, and she even got her gift early! On the downside, there's no way to easily keep track of multiple Shipping Addresses, so if I want to send a gift to Friend A and to Friend B, I have to overwrite everything and it's a fair bit clunky in that regard.
