A natural oval-cut ruby from Madagascar, weighing 0.53 carats and measuring 5.4x4.3mm. The wider oval at 5.4x4.3mm gives generous face coverage for the weight, with the warm transparent red of heat-treated Malagasy ruby showing clearly across the broader oval face. SI clarity keeps the stone transparent and bright face-up despite the natural inclusions present in this clarity grade.
Madagascar is the primary global source of commercial natural ruby, with heated oval faceted stones in the half-carat range among the most widely available natural ruby forms. At 5.4x4.3mm, the broader oval proportions give good visual presence for a ring feature stone or pendant in silver or gold.

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.
