Custom Antique and Old Cut Diamond Ring

Meet

This is your chance to design your own ethical natural diamond engagement ring. Most of these are new diamonds of Indonesian origin, mined by artisanal miners in South Kalimantan, and polished by hand by independent local diamond cutters. 

Now the design...

Choose a diamond that speaks to you and let's get started!

Diamond settings:

• Classic bezel setting with gold all the way around the diamond
• Open bezel setting, which goes around the girdle (edges) of the sapphire, but exposes the culet (the bottom) of the stone
• Prongs
  • Prongs only; The prongs rise up from the base of the ring, without any additional support or security.
  • Wire basket prongs; The prongs rise up from the base of the ring, with a thin wire around halfway at the pavillion (underside) of the stone for extra support.
  • Basket prongs; The prongs rise up from a base or 'basket' into which the gemstone or diamond is set. This offers more security, but can look bulkier than prongs only, especially when the stone has a higher profile.
  • 4 prongs compass, positioned North, East, South and West
  • 4 prongs in the corners

Our white gold is rhodium plated, and the rhodium plating tends to wear off the prongs. So white gold prongs need more care and maintenance. Because the rhodium plating is done by one of our partners, this takes an extra week. 

For stones over 3.5 mm deep, we recommend an open bezel setting rather than a regular bezel setting. This will avoid the bezel setting looking too "chunky" considering the stone has a high profile.

The diamond can be positioned vertically (North to South) or horizontally (East to West).

Band shape:

• Half round band, flat on the inside and rounded on the outside, for a comfortable fit. Around 1.8 mm wide. Can be engraved. 
• Round band, this band tends to spin more and is not recommend if your knuckles are wider than the part of your finger where the ring sits. Around 1.3 mm wide. No engraving possible. 

Additional small stones in the band:

• Plain band, no additional diamonds
• Small sparkling white Canadian diamonds (G-H color, SI clarity) - you choose how many
• Small salt and pepper diamonds from Botswana (you choose how many)

Engraving is on us!

We offer complimentary hand engraving up to 24 characters on the inside of your gold diamond ring to personalize it even more. This is only possible for half round bands, as the round bands are too dainty, and can be selected in the dropdown menu.
