In a follow-up post to the beauty of unheated yet beautiful gemstones, though they are difficult to find, at Heritage Gems, it is possible.
Below are just some examples of fine quality unheated blue sapphires
4.68ct unheated medium blue sapphire
2.34ct unheated vivid blue sapphire
4.06ct unheated medium-deep blue unheated sapphire
5.92ct unheated medium-deep blue unheated sapphire
For fine quality sapphires under 3cts, prices can range anywhere from SGD4,000 – SGD5,900 per carat. 3-5cts, prices range from SGD6,000 – SGD7,900 per carat. For sizes above 5cts, prices start from SGD8,000 per carat. These are current prices as of September 2013.
In-house criteria for fine quality blue sapphires:
- consistent colour throughout gemstone (no colour zoning, colour shades)
- well-cut (no window and no extinction areas)
- with lustre and brilliance
Due to tight supply of fine quality sapphires, prices will unlikely come off anytime soon.
