An oval-cut natural ruby from Madagascar, 0.25 carats, measuring 4.3x3.3mm. Heat treated, the stone shows a warm pinkish-red color - vivid and transparent, typical of heated Malagasy ruby at this weight. Clarity is SI, with inclusions visible under magnification but the stone presenting a lively and reasonably clean appearance face-up. The oval outline is well proportioned, making it a practical choice for setting.
Madagascar is the primary source of affordable natural rubies globally, with heat treatment applied as standard practice to most of the commercial material. At 0.25ct, this stone has enough presence to work as a solo accent or in small cluster settings - suitable for rings, pendants, and earring designs. Natural ruby, loose gemstone, July birthstone.

About ruby
Ruby is the red variety of the mineral corundum. At 9 on the Mohs scale it is second only to diamond, and it is also very tough with no cleavage, so it rarely chips or splits when knocked. Together that makes it one of the most durable gemstones for everyday wear, rings included.
Cleaning
Warm water, a drop of mild dish soap and a soft toothbrush are all you need. Brush behind the stone too, where dust and skin oils collect, then rinse and dry with a soft cloth. Ultrasonic and steam cleaners are usually fine for a faceted ruby, but skip them if the stone has fissures that reach the surface.
Wear and storage
Ruby is very hard, so it can scratch softer gemstones stored with it. Only diamond can scratch it, so keep it apart from diamonds and store it on its own in a gem jar or a soft pouch.
For your jeweler
This ruby is heated, and the color from heating is stable. Ruby handles normal setting, re-tipping and polishing well. If the stone has fissures that reach the surface, keep it out of direct torch flame and acid pickle.
