Why Choose a 1 Carat Ruby?
A 1 carat ruby offers an ideal balance between presence and wearability. It is large enough to create a striking focal point in rings or pendants, while remaining practical for everyday jewelry.
1 Carat Ruby for Engagement Rings
A 1 carat ruby is a popular choice for engagement rings thanks to its durability (Mohs 9) and intense red color. Rubies symbolize love and passion, making them a meaningful alternative to traditional diamonds.
Red Ruby Color & Quality
The value of a 1 carat ruby depends primarily on color. Highly saturated red hues with good clarity are the most desirable. We offer rubies in various shades, from deep crimson to vibrant red.

Good selection, using for custom jewlery for my wife.
Overall Rating -> 10
On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc
Overall Rating -> 10
All items were delivered on time with all items meeting or exceeding my expectations. Cut, clarity and color were very close to the photos and description.
Overall Rating -> 9 
I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.
