Augustus; meaning 'Great' or 'Magnificent' - is exactly what this nouveau solitaire represents. 

Featuring a single 1.60ct Marquise Diamond carefully hand set atop a simple and delicate solitaire band, this is one setting that won't go unnoticed.
As the Marquise is carefully affixed above the band, it offers the appearance of a 'floating diamond'.

This setting has been carefully designed with those in mind who wish to add a future wedding band below it. The simple and delicate solitaire band will allow for any type of of wedding band or eternity setting to be comfortably worn below it. 

The total carat weight of our Augustus Solitaire is 1.60ct and is available to be be made with any carat or any cut of diamond. 

This handcrafted creation has been designed to highlight the beauty of a simple diamond sitting atop the finger. Finished with its simple solitaire band, this is a truly unique piece.

Why VS1?

Many Lab-Grown Diamonds available to purchase in-store and online are typically supplied as a SI1 standard only. The Prestwick Lab-Grown Diamond is as a VS1 standard.

VS1 is a high clarity grade diamond with no eye-visible inclusions and only small, hard to identify inclusions. These diamonds represent the top 5% of all gem quality stones and are highly recommended as a blend of value and quality. VS1 graded diamond are very clear to the naked eye. 

The Prestwick Place VS1 clarity Lab-Diamonds are two to three grades lower than our VVS1 Lab-grown Diamonds. 

Why D Colour?
Diamond colour is typically graded on a scale descending from D, which means no hint of colour, to Z.  A well-cut D colour lab-diamond has a bright, icy white appearance that looks stunningly beautiful.
It is important to note that D colour diamonds are valuable because they are rare, and we believe in providing excellence over cutting corners when it comes to the colour of a Lab-grown diamond.

The Prestwick Diamond is a lab-created stone, meaning it is both ethically and responsibly sourced.
