Five tips for when choosing a blue sapphire for an engagement ring

Colour, Clarity, Cut, Carat and Design

Selecting the perfect sapphire for an engagement ring is an exhilarating experience and Deliqa Gems are ready with the knowledge to assist your choice of sapphire colour, clarity, cut, carat weight and design that best compliments your personality, commitment or love story.

Deliqa Gems has an inspiring collection of coloured sapphires including the famous cornflower blues, champagnes, vivid pinks, padparadscha and harmonious greens to name a few and your sapphire engagement ring colour choice may be determined by past shared experiences, personality or tradition.

The shape or cut of a sapphire is as varied as the myriad of colours. Stunning sapphires for an alternative solitaire, soft cornered cushions, precision cut radiants, delicate ovals or skilfully cut pears from our master cutters, along with the carat weight of a sapphire, can influence what best flatters your ring finger and hand size.

Clarity also plays an important role when choosing the perfect blue sapphire. Sapphires can have inclusions, some of which are visible to the naked eye however this is undisputed evidence that the sapphire is natural. Most of Deliqa Gems sapphires have minimal inclusions and are classed as “eye clean” and thus have beautiful transparency and sparkle.

Blue sapphires make excellent engagement rings. Often the style of an engagement ring is influenced by the shape of the sapphire and design is only limited by your imagination. The sapphire that “talks” to you will also inspire the design. The shape of the sapphire might stand alone as a contemporary solitaire, or the central sapphire may be encircled by a halo of diamonds or partnered with identical side stones as a trilogy ring. Or perhaps your desired look is more a floral cluster, play of colour or a modern organic creation, all of which will play an important part in the overall proportion of a quintessentially hand crafted sapphire engagement ring or jewellery piece.

Should I choose a natural or synthetic blue sapphire?

A natural blue sapphire is extremely rare, formed in nature over many millions of years, mined from the ground, and not produced in a laboratory or subjected to any chemical or heat treatments. Synthetic blue sapphires have the same chemical, optical and physical properties as a natural sapphire but are man-made and produced in a laboratory. “Lab-grown” or “created” sapphires are produced in large quantities and therefore, less expensive than natural sapphires, and must be disclosed by the vendor. To select a natural or synthetic sapphire comes down to personal choice and whether you want something just for the look and wear as opposed to value for rarity and investment.

Are heated blue sapphires as durable as unheated blue sapphires?

Heat treatment is a stable process that enhances the intensity of colour and clarity of sapphires and does not impact on their durability or longevity. Read more about heated vs unheated sapphires here

Does heat treatment diminish the value of a blue sapphire?

Good quality, unheated natural sapphires are increasingly rare to find and for this reason will demand a significant premium price. Heat treatments are permanent and irreversible and used to improve the colour and clarity of a sapphire by recreating the conditions within the earth present during their formation. Heat treated sapphires still have great provenance, however this treatment must be disclosed by the vendor. Heat treatment improves the value of a natural gemstone that may otherwise not be as beautiful, however an equivalent quality unheated sapphire will be more expensive. 

Which is more expensive blue sapphires or diamonds?

Blue sapphires are unique as no two are alike. Attributes of blue sapphire such as their incredible richness of colour, brilliant sparkle, durability and fewer visible inclusions increase their value and make them a popular choice for engagement rings. Sapphires are rarer and more affordable than diamonds and thus allows engagement rings to have a bigger sapphire at a lower cost.

Are blue sapphire engagement rings valuable?

The greatest influences on a sapphire’s value is consumer demand, colour and carat weight. Blue sapphires have been a traditional choice and the most valued of these have a velvety royal blue colour with a vivid saturation or the famous cornflower blues from Ceylon. The rarity of larger size natural sapphires in nature also directly affects the price - the larger the sapphire then the higher the price per carat. Sales of untreated natural sapphires both as individual gemstones and presenting in engagement rings and fine jewellery command higher prices as supply decreases and consumers become more aware of their value. Other sapphire colours are also increasing in popularity and value.

How much are custom made blue sapphire engagement rings?

A one carat custom made blue sapphire engagement ring can start from $3,000 and can be up to $10,000 depending on the quality, colour, colour intensity and provenance.
