Bloodstone has been used and valued for thousands of years, from the ancient Babylonians to the present day. But how much is this unique stone actually worth? Here are some key factors that determine the value of bloodstone:
Rarity – Like many gemstones, supply and demand affects bloodstone pricing. Fine quality bloodstone is relatively rare, especially stones with high concentrations of bright red hematite inclusions. The more intense the color and inclusions, the higher the value. Stones with fewer inclusions are more common and therefore less expensive.
Color – Bloodstone ranges from light green to dark, almost black green. However, deep forest green stones with contrasting bright red hematite inclusions are considered most valuable. Lighter colored stones are less rare and desirable. The red inclusions should appear like blood spots, hence the name bloodstone.
Clarity – As with other quartz gemstones, the clarity of bloodstone affects value. Stones that are more transparent and free from flaws like cracks or pits will be higher quality. Opaque or severely included stones are less valuable.
Cut – Bloodstone is rarely faceted into conventional shapes. The most common cuts are cabochons, tumbled stones, beads, and various ornamental carvings. While faceted bloodstones are unusual, they exhibit excellent cut quality will garner higher prices. Cabochons with a high dome and smooth polish are preferred over flat slabs.
Carat Weight – Like diamonds and other precious gems, bloodstone is measured by carat weight. In general, larger stones are more scarce and valuable. A high carat bloodstone will cost more per carat than a smaller stone.
Treatments – Some bloodstone is heat treated or irradiated to intensify the red color of inclusions. Untreated natural stones are more valuable than treated ones. Buyers should beware of artificially colored imitations like goldstone passing off as bloodstone.
Origin – The majority of bloodstone on the market today comes from India. Australian bloodstone is also quite common. Rare bloodstone from antique European sources, like Germany or Bohemia, can be especially valuable.
With so many factors affecting value, prices for bloodstone can range widely. Small tumbles or beads may sell for $5-$20. Larger cabochons in the 5 to 10 carat range can cost $20-$100. Exceptional collector pieces over 20 carats with perfect forest green and red colors can fetch prices up to several thousand dollars per carat. While not as coveted as fine emeralds or rubies, natural bloodstone is still a unique and valuable collector's gem.
