A north-star moment you can wear. The Polaris Heart features a star-set diamond on a softly domed heart, crafted in 18k gold-plated sterling silver. Inside are two photo windows; the polished reverse is engravable for initials or a date. A smooth hinge and a 45 cm chain keep it effortless for every day—modern sentiment with elevated shine.

• 18k Gold Plated over Sterling Silver for a rich gold lasting shine

• Natural diamond accent

• Locket Size: 16x16mm

• 1 x photo on each side of the locket

• 45cm gold plated Sterling Silver Chain

Layer with a slim satellite or snake chain to echo the star detail, then add medium gold hoops for balance.

Everyday-friendly gold-plated sterling silver. To maintain colour and shine, put jewellery on last after skincare and scent, wipe with a silver polishing cloth after wear, and store clean and dry in a soft pouch. Avoid water exposure and vigorous workouts.

Jewellery Care Tips

A little care goes a long way. Here’s how to keep your LAVANA jewellery looking beautiful.

Stainless Steel with PVD & E-Coating
  • Low-maintenance and water-resistant
  • Safe to wear in the shower, at the beach, or during workouts
  • Rinse and dry after heavy wear (e.g. sweating or swimming)
  • Wipe with a soft cloth to restore shine
Sterling Silver
  • Naturally tarnishes over time — but wearing it often actually helps!
  • Avoid water, chemicals, and sweat where possible
  • Use a silver polishing cloth regularly to restore brightness
Gold Vermeil (2.5 Micron Plated Sterling Silver)
  • Handle with care — remove before swimming, showering, or exercising
  • Avoid contact with perfumes, lotions, or hairspray
  • Store in a soft pouch to prevent scratching and wear
Brass
  • Avoid prolonged moisture, perfume, and chemical exposure
  • Gently wipe after wear and store in a dry, sealed pouch to minimise tarnish
Pearl Care
  • Pearls are delicate and organic — treat them with care
  • Wipe gently with a soft cloth after each wear
  • Avoid sprays, lotions, and perfumes
  • Store separately in a fabric-lined pouch to avoid scratches
  • Pearls should be the last thing you put on and the first thing you take off
Lab-Grown Diamond Care

Lab-grown diamonds are as durable and brilliant as mined diamonds — and with a little care, they’ll stay sparkling for a lifetime.

To keep them looking their best:

Clean regularly with warm water, mild dish soap, and a soft toothbrush

Avoid harsh chemicals and store separately to prevent scratches

Gently wipe after wearing to remove oils or residue

For a deeper clean, use a jewellery-safe ultrasonic cleaner or visit a professional.

Why We Use Three Core Materials

Our collection is made from three carefully selected materials to suit different lifestyles, looks, and budgets. Each one brings its own strengths — whether you’re after strength, softness, or a luxurious finish.

1. Stainless Steel with PVD & E-Coating

Why we use it:

  • Exceptionally strong and resistant to tarnish
  • PVD (Physical Vapour Deposition) coating is 10x more durable than standard gold plating
  • E-coating adds another protective layer to enhance shine and longevity
  • Hypoallergenic and budget-friendly

Best for: Everyday, low-maintenance jewellery you can wear 24/7 — whether at the gym, beach, or in the shower.

2. Sterling Silver with 1 Micron Gold Plating

Why we use it:

  • A timeless fine jewellery metal: lightweight, hypoallergenic, and elegant
  • 1 micron gold plating offers a thicker, more durable finish than most fashion jewellery
  • The perfect balance of quality and affordability

Best for: Refined, stackable gold-look styles that you can wear every day.

3. Sterling Silver with 2.5 Micron Gold Plating (Gold Vermeil)

Why we use it:

  • Reserved for our lab-grown diamond collection
  • 2.5 micron plating is a luxury-grade finish that offers exceptional durability and a rich gold hue
  • Paired exclusively with DEF colour, VS+ clarity lab-grown diamonds for unmatched brilliance

Best for: Heirloom-quality pieces designed to be treasured and worn for years to come.
