The earliest diamonds were found in India in 4th century BC, although the youngest of these deposits were formed 900 million years ago. A majority of these early stones were transported along the network of trade routes that connected India and China, commonly known as the Silk Road.

The Old Mine Cut diamond, a historical style of diamond cutting, gained popularity in the late 18th centuries, particularly during the Georgian, Victorian, and Edwardian eras. Originally used to describe diamonds from older mines in Brazil and India, the term eventually encompassed any diamond cut in a similar squarish shape with a high crown, small table, and large culet. These diamonds were hand-cut and known for their unique, often asymmetrical, facets, which produced a softer, more subtle brilliance than modern cuts.

You cannot look at Old Mine Cut diamonds with a formula in mind, its value is object driven. They are a greater challenge in estimating weight once they have been mounted (especially if they are closed back). The Old Mine Cut diamonds are hand cut, which makes them so special. 

In 1953, GIA formally created its diamond grading system, known as the 4 C's. The 4 Cs of diamond quality are the universally recognized diamond grading system still to be used today.  1n 1955, GIA presented its first diamond grading reports, which became the hallmark of grading reports in the diamond industry. Before this time in antiquity clients did not care about diamond grading. It was based more-so on the size of the diamonds ( according to budget), rarity, style, desirability, and sentiment.  

The earliest synthetic gems were Geneva Rubies, produced around 1885, and sold as authentic gems. However, they were actually "reconstituted" fragments of natural rubies melted together. While the creator of these stones remains a mystery, researchers traced their origins to Geneva, Switzerland.

The name is derived from the Spanish platina, meaning "silver." Platinum was discovered in South America independently by Antonio de Ulloa in 1735 and by N. Wood in 1741, but it had been in use by pre-Columbian natives. 

Target rings, characterized by concentric circles surrounding a central gemstone, emerged during the Edwardian (late 19th/early 20th century) and Belle Époque eras as a romantic, symbolic design. They flourished during the Art Deco movement for their geometric symmetry, featuring contrasting stones like ruby/sapphire halos around diamonds

The Art Deco jewelry period circa 1919-1939 emerged post-WWI, emphasizing bold geometric shapes, symmetry, and modernity in contrast to Art Nouveau’s fluid lines. Defined by the "Roaring '20s" style, it featured platinum, diamonds, onyx, and bright gemstones, often inspired by Egyptian and Asian design.
