Bespoke Jewellery, Made for You
We start from your idea, a sketch, a photograph or the diamond you have in mind, and make the piece in our production unit in Iași: an engagement ring, wedding bands or any other piece of jewellery in 14K gold, 18K gold or platinum.










































Where to Begin
- From a particular diamond. Tell us what you are looking for: carat weight, colour, clarity, proportions, shape, a GIA, IGI or HRD certificate. We select suitable diamonds for you, from our stock or from our suppliers, and send you a video or a photograph.
- From a design. A sketch, an image or a design of your own. We will tell you how it can be made and what might be worth adjusting.
- From a piece you like. Send us a photograph. We create a piece in the same style, designed for the stone you choose.
- From your own stone. Do you already have a diamond or a gemstone, perhaps from an inherited piece? We create the jewellery around it. Before we begin, we examine the stone and tell you whether it can be set safely.
- From a budget. Tell us the amount and, briefly, what you have in mind, and we will suggest the best stone and design options within it.
- From a logo or a symbol. We make pins, cufflinks and corporate gifts in gold or silver, with coloured details in ceramic composite (COLORIT).
The Diamond
We usually suggest natural diamonds of G colour and VVS–VS clarity, or lab-grown diamonds of D–F colour and VVS clarity. If you have something else in mind, for example a natural D FL diamond or a larger diamond within a set budget, we will source it especially for you.
You can choose any shape: round, oval, princess, pear and others. On request, we also work with coloured diamonds, for example blue, or with natural or lab-grown gemstones such as sapphires, emeralds, rubies and others.
Metal and Details
We agree every detail with you:
- 14K or 18K gold (white, yellow or rose) or platinum;
- stones along the band, a halo or hidden stones;
- earring fittings;
- bracelet or chain length;
- engraving.
How It Works
- You tell us what you would like: your inspiration, budget and preferences for the stone.
- We suggest stones, from our stock or from our suppliers. These stones are not held for you until the deposit is paid, so they may become unavailable in the meantime. If your chosen stone is no longer available, we will suggest the closest alternative for you to approve before we go ahead.
- You choose the stone and confirm the order, with a deposit of at least 60%*. If the stone is not in our stock, we order it for you.
- We create the 3D design. The piece is designed to the exact dimensions of the chosen stone, and we send you a render. You may ask for up to 2 minor changes.
- The piece goes into production once you approve the final version.
* Would you rather see a render first? You can pay a design fee, which varies with the difficulty of the project. The fee is deducted from the final price if you place the order for that project. Otherwise, it is non-refundable.

Diamond engagement rings and diamond jewellery come with the Coriolan Extra Warranty, in addition to the 2-year legal guarantee: free annual maintenance for life. With a diamond engagement ring of at least 2,500 RON you also receive a voucher for 7% off wedding bands.
