How much does it cost to buy a 0.50 carat or 1 carat or 2 carat diamond ring in Bangkok, Thailand?


A common question which always pops up is how much does it actually cost to buy a 0.50 carat or 1 carat or 2 carat diamond ring in Bangkok?

Is it cheaper to buy a diamond ring in Bangkok compared to anywhere else in the world?  This question has been discussed before in our other popular blog articles – Where and how to buy diamonds in Bangkok, Thailand?  Or Where to buy the cheapest diamond in Bangkok, Thailand?

But, this still doesn’t answer your question as to how much does it actually cost? So, to give you all actual numbers, I have compiled “an estimate price table.”  In how much a diamond will cost wholesale (in Bangkok or anywhere).

Please note, when compiling these tables I made the following assumptions.  If you do decide to change any of these assumptions prices will change accordingly.



Only Round Brilliant diamonds. For fancy cut diamonds there is a different price list and in general price lower than round brilliants.


All the diamonds in this list are top make grade.  That means excellent cut, excellent polish, and excellent symmetry.  If “Very Good” grade or lower grades are acceptable this will drop the price down from 5% to 10% (on average).


All diamonds are either GIA or AIGS certified.  If HRD, IGI, EGL or no certificate is acceptable this will also reduce the prices drastically.


All diamonds have none or no fluorescence.  If fluorescence is acceptable this will affect prices.


Diamonds are priced based on a price list that is published every week. All dealers, wholesalers or retailers use this as a reference point when buying any diamond transaction.  These price list do change based on market conditions.

From this price list dealers or wholesalers will almost always get a discount price.  While retailers will sell at the list price or higher.  This is true in Bangkok or anywhere.

Based on the diamond assumptions given above.  On average we dealers will get around 10% discount for GIA certified 0.50 carats diamonds. And 15% discount for GIA certified 1.00 carats or 2.00 carats from the price list.


Please note for higher color and clarity diamonds.  Dealers usually get on average a larger discount.  While for lower color (H or below) and clarity (VS2 or below) the discounts are lower.

Again this is because the price for higher grade diamonds starts at much higher point and therefore can afford larger discounts.   All prices below are also just estimates and if you really are interested in buying a diamond ring do contact us for actual diamond pricing based on your criteria.

One thing you will definitely get cheaper in Bangkok than most places in the world is the actual cost of making the ring.  As labor charges is a lot cheaper here.

Prices below does not include the center diamond.

Simple solitaire 18k white gold ring (US Ring size 5 to 6.5):  US$350


Simple solitaire 18k white gold ring with side diamonds (US Ring size 5 to 6.5): US$550 to US$750


Simple solitaire Platinum ring (US Ring size 5 to 6.5): US$750 to US$850


Simple solitaire Platinum ring with side diamonds (US Ring size 5 to 6.5): US$1,000 to US$1,200


As you can see above, the majority cost of a diamond ring is the “center diamond”.  Please remember that the prices shown in this blog are what we wholesalers usually get.  When buying a diamond and manufacturing a ring ourselves.

If you do buy these rings in retail outlets in Bangkok (or anywhere) the prices will usually be much more as they have other overhead costs to cover.

  2. hello sir
    i need price of 0.50 ct size diamond color i clarity vvs1

    1. Hi Raj,
      I wish there is simple answer to your question, however, the price for a 0.50 carat, ‘I’ Color, VVS1-clarity diamond really depends on many factors, which includes the following:
      1) Is the diamond certified by reliable third party certificate (i.e. GIA, HRD, IGI, etc.,). Usually GIA diamonds are sold in premium compare to other certificates. No certificate diamonds are consider a lot cheaper and usually graded higher in two to three color grades higher than comparable GIA certified option.
      2) Do you want the best cut grade which is consider the GIA ‘Triple Excellent’ cut (excellent cut, excellent polish, excellent symmetry) or lower cut grades is acceptable? This grade again will effect the price.
      3) Assume the diamond doesn’t have any undesirable color shades, like brown, green or milky, which will effect the overall look of the diamond.
      Assuming you will like the Top Grade cut – Triple Excellent – GIA certified option, a 0.50 carat diamond will cost around US$1,100 in wholesale (around -33% rap discount) in Today’s market rate.
