navneetgemsParticipant1. Natural Amethyst
2. Howlite (Dyed Turquoise)
3. Carnelien/Onyx/Amber- Check if weight is extremely light then it is amber
4. Black onyx

navneetgemsParticipantBlack star sapphire it is,
navneetgemsParticipantUse a white light torch and when you face light on top of the stone then you will see a vertical line and when you move stone slowly from right to left or left to right then that line moves also.
navneetgemsParticipant@Himanshu – I second you, why these are not diamonds. Here are the reasons –
- Size is very big that is not possible in natural diamond.
- Diamond rough stones do not come in this type of shapes.
So possibly these are marble stones.
