How to Choose GIA Certified Gemstones

Our shop focuses on a small selection of GIA certified gemstones curated in Thailand’s gemstone hubs of Chanthaburi and Bangkok. You’ll mainly find vivid Certified rubies (GIA) and Certified Sapphires (GIA), chosen for color, clarity, cut and overall beauty. Every listed stone comes with independent documentation you can verify anytime through GIA Report Check. We aim to keep the selection premium and manageable, so you can shop confidently without scrolling endless pages.

Use the filters to explore size, color grade and price. If you’re hesitating between two stones, ask for daylight videos and straight-on photos—we’re happy to provide them. Need a ring? Many clients pair their stone with one of our 18K white-gold settings; we can advise on prongs, halo styles and finger sizes. International buyers appreciate our transparent photos, precise measurements and insured worldwide shipping from Thailand. For peace of mind after delivery, please review our clear Return Policy.

What matters most when comparing GIA certified gemstones

• Color: seek vivid, even color with attractive saturation. Rubies should face up red; royal blue sapphires should avoid grey or black extinction.
• Clarity: eye-clean is ideal, but fine inclusions are common and can confirm natural origin.
• Cut & make: well-proportioned stones return more light and look lively.
• Measurements: always check mm dimensions in addition to carat weight to judge face-up size.
• Paperwork: confirm the GIA number on the report and keep it with the gemstone.
