STARLANKA buys rough at source and cuts it in-house in Bangkok, so a stone reaches you without the layers of margin a sphene normally collects between the mine and a retail counter. The price shown is the price — no negotiated tiers.
Retail price is our estimate of what a comparable stone typically costs at traditional retail. It is a comparison figure — not a former price at which this stone was offered.
