The result is a distinctive piece of organic antique jewellery, showcasing the raw material in its purest form.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eThe nugget itself, measuring approx. 10×4mm, displays a classic sponge-like texture. It has been left entirely in its original form, with no shaping or refinement, and is simply mounted on a gold band. Gold nuggets from this period generally test at a natural purity between 21 to 23 karats; this example tests at approximately 22k.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eThe slender band is made of 21k gold and bears a French control mark. The origin of the nugget is uncertain, but it may well derive from one of the major gold-producing regions active at the turn of the 20th century, such as California, Alaska, or Victoria (Australia), all known for yielding high-purity nuggets.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e \u003cstrong\u003eRing size:\u003c\/strong\u003e UK M \/ US 6.25\u003c\/div\u003e\u003cdiv\u003e \u003cstrong\u003eWeight:\u003c\/strong\u003e 1.88g\u003c\/div\u003e\u003cdiv\u003e \u003cstrong\u003eCondition:\u003c\/strong\u003e Band shows some areas of tarnished patina, commensurate with age.
