MIKOSA — Custom Fine Jewellery in Malaysia

Fine jewellery is made with precious metals like gold and set with genuine or lab-grown diamonds, built to last for years. Fashion jewellery, on the other hand, uses plated or base metals with costume stones. It costs less, but it's not made for long-term wear.

Lab-grown diamonds have the same chemical makeup and look as natural ones, but they're grown instead of mined, so they tend to cost less for the same size and quality. Both are graded on the same 4Cs scale, and MIKOSA offers either option for custom pieces.

A custom engagement ring or bespoke diamond piece from MIKOSA usually costs between RM10,000 and RM20,000, depending on the diamond and design you choose. Ready-to-wear pieces are priced lower.

Look for a brand that's upfront about its materials, like gold karat and diamond certification, so you know exactly what you're paying for. Certification from IGI or GIA is one of the clearest signs of that. It also helps to choose a brand that builds pieces around your own design instead of selling from a fixed catalogue, especially for something as personal as an engagement ring.

Yes, MIKOSA's custom diamonds are certified: lab-grown stones through IGI and natural stones through GIA. That means an independent third party has verified the quality and grading, not just MIKOSA.

MIKOSA's custom process starts with a consultation to talk through your design, diamond choice, and budget. From there, the piece is built around those details instead of being adjusted from something off the shelf. Custom fine jewellery like this usually takes a few weeks to complete, depending on how complex the design is.

Yes. MIKOSA's ready-to-wear pieces, including necklaces, bracelets, and earrings, can be bought straight from the site.

MIKOSA offers exchanges within 7 days of receiving an online order, though items generally can't be returned for a refund. Custom, engraved, or made-to-order pieces, including bespoke engagement rings, aren't eligible for exchange, since they're made specifically for you, though MIKOSA may consider exceptions case by case. Exchanged items need to be unused, with original tags, packaging, and your invoice.
