Our stones are sourced and cut by our sister company Crimson Gems in Chanthaburi, Thailand's gem-trading town, and every piece is set by hand in our own Bangkok workshop.

Care
How big is it?
Every piece lists its exact size in centimetres and its weight in the Specifications on the product page. If you would like a photo of the piece next to a ruler, or help with ring sizing, ask our jeweller.
Are the stones real, and can I get a certificate?
Yes. Our gemstones are natural, sourced and cut by our sister company Crimson Gems in Chanthaburi, and any treatment is stated in the Specifications. An independent laboratory certificate can be made to order: add the Gemstone Certification Add-On to your cart.
Will I pay customs duties or taxes on delivery?
No. Shipping is free and insured, and duties and import taxes are included in the price you pay, so there is nothing more to pay on delivery. See our shipping policy.
What if I want to return it?
You can return any piece within 30 days of delivery, unworn and in its original packaging. Refunds go back to your original payment method. See returns & cancellations.
Will the gold plating wear off?
18K gold plating softens gradually with everyday wear. Keep it away from perfume, lotion and water to make it last, and whenever it fades, send it to our Bangkok workshop and we will re-plate it for life. See warranty & care.
