FAQ

• What are “unheated” gemstones, and how are they different from treated ones?
  Untreated gemstones are natural stones that have not undergone heat or chemical enhancement. Their color and inclusions are entirely formed by nature. Compared with heat-treated stones commonly found on the market, natural unheated gems are significantly rarer and hold greater value for both collectors and investors.
• What should I look for when selecting investment-grade colored gemstones?
  Key factors include rarity, origin, clarity, color saturation, and cut. We recommend choosing stones accompanied by certification from an independent gemological institute—particularly those issued by internationally recognized laboratories, ensuring authenticity, quality, and long-term value.
• Why are colored gemstones suitable for collection and wealth preservation?
  Fine natural colored gemstones are inherently rare and culturally prized worldwide. Their limited supply and enduring beauty give them strong potential for long-term appreciation. Beyond aesthetics, they embody value, legacy, and emotional significance. To learn more about gemstone investment, you’re welcome to book a private consultation.
• Do JUSTLEE pieces come with international certification? What’s the difference?
  All collectible gemstones from JUSTLEE are accompanied by certificates issued by reputable international gemological laboratories.
  Without certification, gemstones may face valuation and resale disputes, making it difficult to ensure the buyer’s protection or the stone’s true worth.
• Which international institutions authenticate JUSTLEE gemstones?
  We work exclusively with world-renowned laboratories, including:
  GIA (USA), GRS (Switzerland), SSEF (Switzerland), Gübelin (Switzerland), and AIGS (Thailand)—each widely recognized for their precision and integrity.
• How do gemological laboratories differ from one another? Which do you recommend?
  Each laboratory may differ slightly in how it defines treatments, terminology, and origin reporting. For accuracy and long-term credibility, we recommend choosing internationally respected institutes such as GIA, GRS, SSEF, Gübelin, or AIGS.
• How does a gemstone’s origin affect its value?
  Origin is a major factor in determining value. For instance, Burmese rubies, Kashmir sapphires, and Colombian emeralds are globally celebrated for their exceptional quality. However, ultimate worth depends on overall characteristics—color, clarity, and cut—which define a gem’s beauty and rarity. To explore more, please book a professional consultation.
• Can JUSTLEE help me source a specific gemstone?
  Absolutely. Please contact us for a private sourcing consultation, sharing your preferences—such as gemstone type, budget, and design style. Our experts will locate suitable options across the global market and provide professional evaluations and recommendations.
• How long does a bespoke creation take, from gemstone selection to completion?
  Once your custom design is confirmed, production typically requires 10–12 working weeks, depending on design complexity and certification schedules. For special techniques or rare materials, we recommend booking in advance.
• What do I need to prepare for a custom jewelry order? Can I use my own gemstone?
  We welcome your ideas and inspirations—our design team will create a piece exclusively for you. To maintain quality and harmony in each design, we currently work primarily with JUSTLEE’s curated gemstones.
• Do you accept international commissions? Is online service available?
  While our bespoke services are primarily based in Taiwan, we also welcome overseas clients to schedule a consultation to discuss international commissions and details.
• Does JUSTLEE provide after-sales service and warranty?
  Yes. Every JUSTLEE piece comes with long-term care and service support. Should you experience any issue during wear, our specialists will gladly provide maintenance and professional repair upon appointment.
• How should I clean my jewelry, and how often?
  Jewelry should be cleaned regularly. For pieces set with gemstones or pearls, professional cleaning is recommended. You may use a soft brush with mild soap and water, followed by a thorough rinse.
  We suggest bringing your jewelry to JUSTLEE once a year for inspection and professional polishing, and checking the structure every 1–3 years—including prongs, clasps, and settings.
• How should I store my jewelry?
  To prevent scratches, store each piece separately in its original jewelry box.
  Necklaces and chains should be fastened and laid flat to avoid tangling. Avoid storing multiple pieces together without protection.
