Our Products
Our offered Product range includes Gum Copal and Damar Batu.
Gum copal, also known as manila copal, is a resin produced by the sap of the forest tree (Daniellia sp.), due to common impurities and differences in regions, gum copal ranges in colors from blacks to yellows to whites. Gum copal, along with ivory and slaves, was a significant export from East Africa in the nineteenth century. Gum copal exists in a state very similar to that of amber but with some primary differences. It is commonly mistaken for amber and often times sold at gem shows or other areas as amber. Unlike amber, gum copal is usually only 100-1, 000 years old and it has not yet fossilized. [2] Gum copal usually sells for $750-$1500 USD per metric ton in rock form and $1500-$6500 USD Per metric ton in powder form. [3]
Damar Batu, or Damar Gum, is obtained from the Dipterocarpaceae family of trees in India and East Asia, principally those of the genera Shorea, Balanocarpus or Hopea. Most is produced by tapping trees; however, some is collected in fossilised form from the ground. The gum varies in colour from clear to pale yellow, while the fossilised form is grey-brown. Dammar gum is a triterpenoid resin, containing a large number of triterpenes and their oxidation products. Many of them are low molecular weight compounds (dammarane, dammarenolic acid, oleanane, oleanonic acid, etc.), but dammar also contains a polymeric fraction, composed of polycadinene.
