Colored Stone Activity Is Picking Up

MARKET IN BRIEF:April 14, 2005…Early spring found buyers searching for better ruby and sapphire in Asia. Dealers report that more unenhanced material is being offered on the Thai and Sri Lankan market. Buyers, concerned about undisclosed treatments, brought about change by requesting unenhanced material. One buyer who recently traveled to Sri Lanka noted that there is a risk the market will swing too far from treated goods. He recently observed several yellow sapphires with washed-out colors that would have benefited from heat treatment being offered at a big premium. Better natural yellows have a strong market but the pale material that is being offered at high prices is slow to move. However, prices for natural untreated material in general are strong due to higher demand. Sales continue to lag for gems in the commercial and good-quality grades.

Blues, greens, yellows, and purples are influencing fashion this spring. Pink sapphire is still strong and demand for natural yellow sapphire is up.
