| 説明 | (10 millimeters across at its widest)---------------------------This is a brilliant cut, synthetic gemstone called "titania", which is titanium dioxide, TiO2. This chemical exists naturally as the mineral rutile. Titania is produced as a diamond simulant - it is can be near-"colorless", but is often pale yellowish. Compared with diamond, titania has greater "fire" but is much softer.---------------------------See info. at:en.wikipedia.org/wiki/Rutile#Synthetic_rutile |
