Blackoste is a demi-fine jewellery brand offering high-quality, hypoallergenic, and anti-tarnish pieces inspired by Korean style and everyday elegance. Our designs combine meaning and minimalism, making them perfect for gifting or daily wear.

We are based in India and ship our jewellery across the country, ensuring quick delivery and safe packaging.

Yes! All our pieces are designed for daily use, with durable finishes and materials that are resistant to tarnishing and safe for sensitive skin.

Blackoste specialises in demi-fine jewellery, crafted from premium materials like stainless steel, sterling silver, and high-quality gold plating. Every piece is hypoallergenic, nickel-free, skin-friendly, and anti-tarnish, designed to last for years while maintaining its shine and comfort.

Demi-fine jewellery sits between fine jewellery and fashion jewellery — it combines premium metals and plating for lasting durability but at a more accessible price than solid gold or platinum. This means you get the luxury look and feel without the high-end price tag, and it’s safe for everyday wear.

Many of our designs feature AAA-grade cubic zirconia, high-quality crystals, and select semi-precious stones chosen for their brilliance, durability, and affordability. While we do not use high-value precious stones like diamonds or emeralds in most designs, our pieces are carefully crafted to give the same elegant, luxurious look.

Anti-tarnish means the jewellery has a special protective layer that prevents dullness, discolouration, and rust over time — even with regular wear.

Yes! All our jewellery is nickel-free and tested to be gentle on sensitive skin.
