I purchased the raw stone then had them cut and polised, after that i handed them to the goldsmith and finally make them available on my store. Thats why i am certain about the stone, about what they are and whether they are natural. These are tourmaline and 100% natural. Ideal meaningful gift for your loved one or any special occasion or life event or as a treat for yourself at the important time of your life because my designs are uncommon and my products are endurable and long-lasting ABOUT MY PRODUCT <<<<<Silver>>>>> + For the record, every metal part in any item is silver. It can be 925-silver or 950-silver. <<<<<Gemstones>>>>> + As regard stones, they are all natural stones. I don’t like lab-grown gemstones because for me it doesn’t have a soul. Stones I use can be semi-precious gemstones or gemstones but I would like to call them generally gemstones.
