What Makes Moissanite a Smart Choice?
Moissanite is one of the most popular diamond alternatives in the UK, offering exceptional sparkle, strength, and ethical value at a fraction of the cost. With a refractive index of 2.65, it reflects more light than a diamond, giving engagement rings a bright, eye-catching shine.

Because moissanite is lab-grown, it avoids the environmental harm and labour issues associated with diamond mining. This makes it a leading choice for uk shoppers who want ethical, conflict-free jewellery.
Another major advantage is affordability. Moissanite can cost up to 90% less than diamonds, allowing uk buyers to choose larger carat sizes or more intricate designs while staying comfortably under £500.
With DEF colour, VVS clarity, and proper certification, moissanite provides premium beauty and long-lasting value.
