Pure purple diamonds are precious stones that are exceedingly uncommon in nature and often occur as synthetic diamonds. Pure purple ranks as the second rarest hue in diamonds.
Colored diamonds can either exist naturally or be made artificially. These gemstones can be manufactured into an array of different shades by using laboratory techniques such as color enhancements, irradiation and intense pressure applications.
Pure purple diamonds without color modifiers mostly occur under the size of two carats. These modifiers, called secondary hues, include red, pink and gray. Synthetic purple diamonds contain needle-like color zones and are categorized into violet diamonds with a blue-gray tint and purple diamonds with a reddish-pink shade.
