For that few number of records, the result should be returned quick unless you have no index defined on your table, the dataset is massive, or if your table has millions of rows.

Put indexes on these columns:

IDstkStones

IDmstListsShape

IDmstListsClarity

IDmstListsColor

IDmstListsCuletCondition

IDmstListsCuletSize

Reporting by definition is different. Otherwise we would just show it on the screen.

SELECT
       stkStones.ID,
       stkStonesDet.DiamondSKU,mstShape.Name AS ShapeName,
        mstShape.SortOrder AS ShapeSortOrder,

FROM stkStones
       INNER JOIN stkStonesDet on stkStones.ID = stkStonesDet.IDstkStones
       LEFT OUTER JOIN mstLists as mstShape on mstShape.ID = stkStonesDet.IDmstListsShape
       LEFT OUTER JOIN mstLists as mstClarity on mstClarity.ID = stkStonesDet.IDmstListsClarity
       LEFT OUTER JOIN mstLists as mstColor on mstColor.ID = stkStonesDet.IDmstListsColor
       LEFT OUTER JOIN mstLists as mstCuletCondition on mstCuletCondition.ID = stkStonesDet.IDmstListsCuletCondition
       LEFT OUTER JOIN mstLists as mstCuletSize on mstCuletSize.ID = stkStonesDet.IDmstListsCuletSize

Hi,

From your description, they left join same table, mstLists . You could change to AND instead of LEFT JOIN. Please check below query:
```
SELECT
        stkStones.ID,
        stkStonesDet.DiamondSKU,mstShape.Name AS ShapeName,
        mstShape.SortOrder AS ShapeSortOrder,

FROM stkStones
        INNER JOIN stkStonesDet on stkStones.ID = stkStonesDet.IDstkStones
        LEFT OUTER JOIN mstLists as mstShape on mstShape.ID = stkStonesDet.IDmstListsShape
        AND mstShape.ID = stkStonesDet.IDmstListsClarity
        AND mstShape.ID = stkStonesDet.IDmstListsColor
        AND mstShape.ID = stkStonesDet.IDmstListsCuletCondition
        AND mstShape.ID = stkStonesDet.IDmstListsCuletSize
```
Thanks.
