The Made-to-Order Process

If a piece of jewellery you love is out of stock, we can often handcraft a unique version specifically for you. Because the market value of precious metals and gemstones fluctuates, the price listed is a guide price. Here is how it works:

  • Tap the WhatsApp button below to check current timescales and get an accurate price quote for your preferred metal (e.g., Silver, Gold, or Platinum).
  • We source the materials specifically for your order and confirm the exact time it will take to make (typically 4 to 6 weeks).
  • No obligation: You only pay once we agree on the final design, price, and timeline together.

Description

This elegant radiant cut moissanite ring is a very contemporary design. The gemstone is set going across the finger instead of the traditional angle. This makes the stone look larger as it covers more of the finger width wise but doesn't take up too much room from the knuckle to the finger joint, allowing other rings to be stacked next to it, such as a wedding and eternity ring. The setting has a raised crossover design to the claws and this also means another straight band can sit next to it without needing shaping. 

This design can come in white or yellow gold as well as the platinum one photographed here. 

A radiant cut gemstone is rectangular but it has more facets than a step or emerald cut. This gives it more life. The moissanite measures 7mm by 5mm. It is approximately one carat and a fantastic price for a designer handmade engagement ring. 

Moissanite is a laboratory grown gemstone which means it has not been mined, making it a more environmentally friendly alternative to a diamond. Moissanite has a higher refractive index than diamond which means that light travels faster through it giving it even more sparkle. If you would like to know more about how moissanites compare to diamonds I have a great blog that compares them - Is it time to go green when shopping for diamonds?
