Product Description

Royal blue has always commanded a room. This ring makes sure you do too.

A generous, big-carat lab-grown sapphire in deep royal blue, set in S925 Sterling Silver with an adjustable band that fits any finger. This is not a subtle piece — it is a statement, worn with the quiet confidence of someone who knows exactly what they like.

Why You'll Love It

  • Bold, saturated royal blue — lab-grown sapphires are among the most vivid blue gemstones available, known for their skin-brightening colour effect
  • Big carat presence — a generously sized stone that makes an immediate impression without feeling overdone
  • Adjustable fit — one band, any finger, any hand. No sizing needed, ideal for gifting
  • S925 Sterling Silver — hypoallergenic, durable, and polished to a brilliant finish
  • Guilt-free luxury — ethically created with the same optical and chemical properties as a mined sapphire, at a fraction of the environmental cost

Frequently Asked Questions

To keep your LabGrownPro jewellery looking its best:

  • Avoid contact with perfume, cosmetics, chlorine, and perspiration
  • Gently wipe with a soft cloth after wearing
  • Store each piece separately in a jewellery pouch or box to prevent scratching
  • Clean occasionally with mild soapy water and a soft brush, rinse thoroughly and pat dry
  • Store S925 silver pieces in a sealed bag when not worn to prevent tarnishing

Lab-grown gemstones are created in a controlled environment using the same natural processes that form gemstones underground — just faster and without the environmental impact of mining. They are chemically, physically, and optically identical to mined gemstones, and are graded by the same standards. At LabGrownPro, every gemstone is ethically created, visually stunning, and offered at a fraction of the cost of mined alternatives.

We use standard Australian (AU/UK) ring sizing. To find your size, measure the inner diameter of a ring that fits well, or wrap a strip of paper around your finger and measure the length. Visit our Ring Size Guide for a full size chart, measurement tips, and international size conversions. If you are between sizes, we recommend choosing the larger size.
