A natural aquamarine from Africa, 7.40ct, in an oval cut measuring 12.8x10.7mm. The stone displays a pale, washed blue-green color, light in tone with a gentle aqua quality and partial transparency. Natural inclusions give a slightly milky, veiled character throughout, consistent with SI clarity in an untreated stone of this size and origin.
African aquamarine tends toward soft, neutral blue tones, and this stone fits that profile honestly. At nearly 13mm face width and over 7ct it is a sizeable piece for the price. Suited to bezel settings that support a larger stone, layered pendant work, or mixed-media designs where the translucent, hazy blue quality is used as a feature rather than worked around.
Natural aquamarine, March birthstone, sold loose.

About aquamarine
Aquamarine is the blue to blue-green variety of beryl. At 7.5 to 8 on the Mohs scale with only poor cleavage, it is a good stone 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. An ultrasonic cleaner is usually fine for a clean faceted aquamarine, but skip steam: sudden temperature changes can crack it.
Wear and storage
Aquamarine is hard enough for everyday wear, and it can scratch softer gemstones stored with it. Harder stones such as topaz, sapphire, ruby and diamond can scratch it, so store it on its own in a gem jar or a soft pouch.
For your jeweler
This aquamarine is untreated. Aquamarine takes normal setting well, but keep it out of direct torch flame: sudden heat can crack it or change its color.
