Frequently Asked Questions
Is this blue sapphire suitable for everyday jewellery such as an engagement ring?
Absolutely. With a Mohs hardness of 9, sapphire ranks as one of the hardest and most durable gemstones in existence, second only to diamond. This makes it exceptionally well-suited for pieces intended for daily wear — including engagement rings, stacking bands, and bracelets — where resistance to scratching and chipping is paramount. Its resilience is matched only by its beauty, making it a stone you can wear with complete confidence for a lifetime.
What makes the oval cut a desirable choice for this royal blue sapphire?
The oval cut is a masterstroke of lapidary craft — its elongated silhouette maximises the visible surface area of the stone, allowing more of that rich royal blue colour to radiate outward. The curved facet arrangement creates a continuous play of light across the gem’s face, enhancing its natural brilliance and depth. Measuring 5.5 x 4.3 mm, this particular oval is wonderfully proportioned, lending itself beautifully to solitaire settings, east-west rings, and drop pendants alike.
Which metal settings complement a royal blue sapphire best?
Royal blue sapphires possess a remarkable versatility that harmonises with a broad range of precious metals. Platinum and white gold offer a cool, contemporary contrast that allows the blue to appear vivid and undiluted — a pairing often favoured in modern fine jewellery. Yellow gold, by contrast, lends a timeless warmth and richness that evokes the classic sapphire jewels of royal heritage. Rose gold strikes a romantic middle ground, softening the intensity of the blue with a gentle blush tone. The choice ultimately reflects your personal aesthetic and the setting style you envision.
How should I care for and maintain my blue sapphire gemstone or jewellery piece?
Caring for a sapphire is a pleasingly straightforward matter, owing to its exceptional hardness and stability. To keep its lustre pristine, clean it gently with a soft-bristled brush, warm water, and a mild, non-abrasive soap, then rinse thoroughly and pat dry with a lint-free cloth. Avoid exposing it to harsh household chemicals or ultrasonic cleaners without professional guidance. When not being worn, store your sapphire piece individually in a soft pouch or lined jewellery box to prevent contact with other gemstones or metals that could cause surface abrasion.
