Description from the seller
Ring Black Chalama Opal / new
Set in 925 sterling silver
10.0 mm x 8.3 mm
Weight: 2.66 g / 13.3 ct
New and unused
Ring size:
EU 54 - 55 (sits exactly in between)
UK N - O
US 7.0
FR 14 - 15
Inner diameter: 17.35 mm
Black opals occur, like their other colored counterparts, as rounded to knobby masses without recognizable crystal structure. Their beauty usually reveals itself only when polishing this type of opal.
A characteristic feature of this form of opals is their opalescence, expressed as an intense rainbow sheen.
Additionally, the base layer of this opal is dark, grayish to black, which gave it this name.
Black opals, like other opals, form from silicon-containing fluids that crystallize in sedimentary or volcanic rocks. Their characteristic shine can be traced back to water inclusions within the mineral.
