Frequently asked questions about tanzanite jewelry
What's the difference between gold-filled, gold-plated, and solid gold?
Solid gold (10K, 14K, 18K, 24K) — durable, hypoallergenic, holds value. Costs $100-500+ per piece. Gold-filled — a thick layer of gold mechanically bonded to base metal, lasts 10-30 years before wear. Gold-plated/vermeil — a thin gold electroplated layer over silver or brass, wears off in 1-3 years. For everyday wear, solid gold or gold-filled. For occasional wear, plated is fine.
Where can I buy real jewelry that won't tarnish?
Solid 14K or 18K gold (Mejuri, Ana Luisa, Catbird) and sterling silver (.925) are tarnish-resistant if not exposed to chemicals (chlorine, perfume, soap). Brilliant Earth and VRAI offer real gold + lab-grown diamonds at lower-than-traditional jeweler prices. Avoid 'fashion jewelry' under $50 — almost always plated, will turn green or strip in months.
How do I clean gold jewelry at home?
Soak in warm water + few drops mild dish soap for 15-30 minutes, gently brush with soft toothbrush, rinse, dry with microfiber cloth. Skip ultrasonic cleaners for pearls, opals, emeralds (loose stones). Polish silver with a silver-polishing cloth (Wright's, Hagerty's). For diamonds and hard stones, the gentle soap method works well.
Lab-grown vs natural diamonds?
Lab-grown diamonds (VRAI, Brilliant Earth, James Allen) are chemically and visually identical to mined diamonds, cost 30-50% less, and have zero ethical concerns about origin. Resale value is lower than natural (the gap is widening as labs scale up). For engagement rings, lab-grown is the smart-money choice in 2026. Natural still holds prestige for some buyers.
What jewelry holds its value?
Solid gold (always — gold rarely loses value, often appreciates), branded pieces (Cartier Love bracelet, Tiffany Lock series, Van Cleef Alhambra), and certified diamonds over 1 carat with strong cut/color/clarity. Avoid investing in random fashion jewelry, gold-plated pieces, or trend-driven brands — those depreciate the moment you walk out of the store.
How can I tell if jewelry is real?
Look for hallmarks (10K, 14K, 18K, 925, PLAT) stamped on the metal. Magnet test: real gold and silver are not magnetic. Acid test kits ($15 on Amazon) verify metal purity at home. Jewelers offer free authentication. For diamonds, fog test (real diamonds disperse fog instantly; fake diamonds hold fog longer) is a quick at-home check.
